Featured Expert: Dr. Charlene Hoi, PhD

How long does it take to get a PhD? On average, PhD programs are 4 or 5 years long. The time it takes to get a PhD is slightly longer in the US, between 4-6 years, because these programs tend to be more structured. If you want to know how to get a PhD in Canada or Europe, you can expect it to take 3-5 years. However, there are PhD programs that take longer, such as part-time programs, or are extremely short, like online accelerated PhD programs. Ultimately, how long it takes to get a PhD is up to you. In this article, we’ll look at the average PhD program lengths, the typical PhD timeline, and tips on how to get your PhD finished faster.

How long does it take to get a phd.

On average, it takes 4-5 years to complete a Doctor of Philosophy (PhD) program. In the US, most PhD programs are between 4-6 years, while in Canada they are typically shorter, around 3-4 years.

Some students take longer than 6 years to complete their PhD, but in general the longest time it takes to get a PhD is capped at 8 years. If you’re enrolling in a part-time PhD program, for instance, your timeline will probably be extended to 6-8 years.

The shortest PhD programs out there are accelerated or sometimes online PhD programs. Some of these are only 1-2 years long, but there are comparatively fewer programs available, and they are only suitable for certain fields and careers which require less intensive research which defines most PhD programs.

One of the main reasons why it takes many years to get a PhD is because these programs are comprehensive and the requirements to graduate are extensive. Most have a set number of credit hours you need to complete, examinations to write, plus you’ll need to write your PhD thesis or dissertation, unless you pursue a PhD without dissertation .

There are certainly ways to shorten the PhD application timeline and time to graduate, which includes enrolling in a shorter program if possible, increasing your course load or the number of research hours you can dedicate per week, but generally a PhD will still take some time.

Even if you want to do a PhD without a master’s degree first, such as by applying to a direct entry PhD program, the program is still usually 4-5 years long.

We’ll take a look at the typical PhD timeline and how long it takes to get a PhD normally. After, we’ll cover some tips on how to get your PhD done faster or how you can avoid dragging things out.

In North America, the typical PhD program is divided into two stages. The first stage is where you complete all the required coursework, comprehensive exams and other academic requirements, depending on the program. The second stage is when you submit a proposal for original, independent research, get it approved and start working on your thesis or dissertation. Your PhD culminates with your thesis defense. Once your thesis has been approved, you’ll be eligible to graduate.

This timeline is somewhat flexible, as you might complete the first stage in 1 or 2 years but take longer to complete your dissertation. For the purpose of this general PhD schedule, we’ll assume your PhD program is a typical length of 4-6 years.

Application Stage

We’ve included the application stage of getting your PhD here first because the grad school application timeline can take several months to put together your application package and hear back about acceptance to a program. Secondly, because the application stage involves some critical steps you’ll need to complete in order to get your PhD.

1. Research proposal

To apply to a PhD program, you’ll most likely be required to submit a research proposal and be prepared to answer any research proposal questions your advisor will have. This is your “proposal” of what research question you will explore during your studies at a program, or an outline of what research topic you want to pursue. If you’re not sure how to write a research proposal, check out these Oxford PhD proposal samples or a Cambridge PhD proposal sample.

2. Application materials

The admission requirements for a PhD can vary from program to program, but here are the general components of a PhD application:

• Required prerequisite coursework
• Official transcripts (and minimum GPA)
• Graduate school statement of purpose
• CV for graduate school or research resume
• PhD motivation letter

Some programs may also ask you to submit additional essays, such as a letter of intent, research interest statement or grad school career goals statement .

Many PhD programs also invite you to a grad school interview to get to know you better. Be ready for common graduate school interview questions such as “ tell me about yourself ” and “ why do you want to do a PhD ?”

PhD Years 1-3: Coursework Stage

1. orientation.

Your PhD program will usually begin with your orientation, where you’ll learn about the program’s individual structure, requirements and expectations. You’ll also either choose or be assigned an academic advisor and schedule an initial meeting with them. Your advisor will be a member of the university faculty who will act as your support while you complete your research and write your thesis.

2. Coursework

The first year or two of your PhD will involve completing required advanced coursework in your field. You’ll attend lectures and seminars and you may participate in research projects with department faculty or fellow graduate students or even lab work, depending on your field.

3. Electives

Along with required coursework, you’ll have the chance to take elective courses that interest you or relate to your field. It’s important to choose electives that will enrich your program. Choose ones that really interest you, that might help inform your PhD research or that will help you fulfill your credit requirements.

4. Extracurriculars

PhD programs sometimes have extracurricular activities or additional requirements outside the classroom. This can include internships or a practicum you need to complete for credit, or you might be interested in attending academic conferences or relevant events to socialize and network you’re your colleagues in the field.

5. Comprehensive exams

The coursework stage of your PhD program will end with comprehensive exams , sometimes called qualifying or preliminary exams. These are your “final exams” to make sure that you completed the necessary PhD coursework and that you’re ready and qualified to take on your own independent research in the next phase.

1. Thesis proposal

You may recall that you submitted a research proposal as part of your PhD application, and this step of the process is similar. Your thesis proposal is just like your research proposal, but it’s a more refined and developed version. Throughout your coursework, your research question might have changed or you might have changed course a little bit. If you’re still thinking about your PhD topic , take the time to solidify it before you reach the thesis proposal stage.

Your research proposal might have been a first draft, while your thesis proposal is your official announcement of: this is what I propose to research in this PhD program.

Depending on your field and the program, you thesis research might involve a great deal of lab work, or data collection or fieldwork. Whatever the case, your thesis proposal is a complete outline of what you intend to do for this independent research project and the steps you’ll take.

2. Thesis approval

Once your proposal is written, you’ll submit it for approval. Your academic advisor, PhD supervisor or the PhD committee overseeing your program will review it and either approve it or make suggestions for changes. Once it’s been polished and finalized, you’ll be given the go ahead to start conducting your research.

3. PhD research

Your research alone will probably take you several semesters to complete. On top of the fieldwork, lab work or data collection and analysis you’ll be completing, you’ll be using this time to write and review. Writing your thesis or dissertation takes a fair number of hours to outline, draft, edit and complete. It also means hitting the books to complete a literature review of your research topic so you have a complete background understanding of your chosen topic and how it will inform your research.

Your research and the preparation of your thesis is really the biggest part of this second stage, and is probably the longest part of your PhD altogether.

4. Extra requirements

When you’re not deep in your research, you’ll be completing other requirements of your PhD program or additional duties that enrich your education. Some programs require you to dedicate some hours to teaching, whether it be leading seminars for undergraduate students or acting as a teaching assistant for university faculty.

You’ll also be strongly encouraged to publish as a graduate student , so you may be involved in the research projects of faculty members or other grad students when you’re not working on your dissertation.

5. Thesis submission and preparation for thesis defense

When you’re finished writing your thesis and you’re ready to submit it, it’s critical to know how to prepare for thesis defense . Because not only do you have to complete this original, new body of research work, you have to get the approval of your PhD committee to put it out into the world.

Your thesis defense is essentially the final presentation of your PhD.

6. Thesis defense

Your thesis defense is an oral presentation of your research project, but it also involves submitting your written document to be reviewed. Essentially, you’ll present the entirety of your thesis to the PhD supervising committee, including your findings and conclusions. From there, the committee will ask thesis defense questions . Your answers will defend your methodology and results to the committee, basically proving the value and validity of your work. While this is an evaluation of sorts, it is also your opportunity to share your original ideas and invite further research into your topic.

After your defense, the PhD committee will either approve your thesis or send it back to you with edits or changes to be made before it can be formally approved.

Graduation and Postdoc

Once your thesis has been approved, congratulations! You’ll be eligible for graduation and be awarded your degree. Now that you’ve finished this marathon, you can choose to pursue further studies or start looking for a job after grad school .

With a PhD, you have many different options for positions in your field. You might want to know how to find a job in academia or how to get a tenure track position at a university if you’re interested in teaching others. PhD graduates who decide to transition from academia to industry or who would rather work outside the realm of academia can find industry jobs after PhD that suit their skills and experiences.

Either way, you’ll need to prepare for how to find a postdoc position, explore what the career options are for you, decide what your career goals are and start sending out applications. Remember to prep your postdoc resume and get read for postdoc interview questions , since the job hunt will begin soon after you finish your PhD!

Is it possible to get your PhD done faster? What are some ways you can speed up the process and avoid taking 8 years to complete your graduate studies? Luckily, there are many key ways you can make your journey through grad school easier and speed things up a little, from the type of PhD program you choose to the habits and skills you cultivate during your program.

#1 Enroll in an accelerated program

The first way to guarantee it will take less time to get your PhD is to, of course, enroll in a shorter PhD program. Direct entry PhD programs allow you to enroll once you’ve completed your bachelor’s degree in exceptional circumstances. Note that these are not the easiest PhD programs to get into , as your academic record needs to be excellent, and you’ll likely need prior research experience and you may even need to have publications already. However, a direct entry PhD program is around 4-5 years, but it allows you to skip the 1-2 years it would take to earn a master’s degree.

You can also choose to enroll in an online or accelerated PhD program that is designed to be much shorter than the traditional PhD. Once again, though, these programs are not available to students in every field, so you may need to research whether there are any options for you.

#2 Choose the right mentor

One of the first things you can do to ensure your PhD is smooth sailing is to choose the right mentor or academic advisor. Many programs allow you to choose your advisor, while some assign one to you. Whatever the case, it’s important to establish a strong working relationship and clear expectations early on.

One of the first things you’ll do as a PhD student is meet with your advisor. Take the time to discuss with them what your expectations for the program are, ask questions and ask them what their expectations are of you. Your advisor is there to help you and advise you, and they have resources and connections you can use to your advantage. But they are also working with a busy schedule and might be advising more than one PhD student, too. A mutually respectful relationship with open communication will ensure fewer interpersonal hurdles down the road.

#3 Earn credit hours faster

One way you can shave some time off your PhD is by earning your credit hours faster and getting to the research and thesis-writing stage faster. This might mean you take on a full-time course load or ask your advisor for ways to earn extra credit, such as participating in research projects. Some PhD programs will give you course credit for previous graduate level coursework you might have completed during your master’s degree, or for certifications and professional education you completed outside of school.

#4 Keep your thesis focused

When you get started on your research, it’s easy to feel overwhelmed with the amount of work you need to complete, with the writing of your thesis on top of it all. One way to keep your research hyper-focused and on point is to keep your thesis topic narrow. If your subject is too broad, you’ll be spending way too much time in your research. Give yourself clear objectives and scope, and don’t deviate from your PhD proposal if you don’t have to.

There may be a million questions you want to explore within your PhD topic, but there will be other opportunities to explore them. Keep your focus narrow so you don’t spend years and years asking and answering research questions!

One of the best things you can do to get your PhD done faster and adjust to the experience of graduate school is to change your thinking. Adopt a growth mindset so that you’re open to new learning, willing to listen to constructive feedback on your proposal or thesis and willing to grow your skills. A PhD is an advanced program, and you’ll already be very skilled, but it is also an opportunity to learn and grow. There will be challenges for you, so be ready to meet and overcome them instead of letting them draw you back or slow you down.

#5 Develop your professional skills fast

A PhD is an opportunity to grow your professional skillset as much as it is an opportunity for you to contribute meaningfully to your field. If you haven’t already been working on skills such as communication, presenting or lecturing and writing, now is the time to start.

Strong writing skills will help you get your thesis finished and edited faster, as you’ll be more familiar with the process and understand what makes a strong document. It’s also a useful skill to learn how to write effective funding proposals or grant proposals. You may need to do so to secure funding for your research, but it’s a highly valuable skill in the workforce, too.

Good presentation skills will help you during your thesis defense or if you’re asked to present during a conference. They will also help you build confidence in your voice and ideas and make you a better communicator when you’re networking or job searching.

#6 Keep to your schedule

This is maybe the most important skill if you want to finish your PhD faster: make a detailed schedule and hold yourself accountable to it. If you like, you can plan out your entire PhD week by week from Day 1. Write down what your course schedule is, when you’ll do research and how many hours, when you’ll write and how many hours, what extracurriculars or personal activities will take up your time and so on.

A detailed schedule gives you an overview of your PhD and a timeline of when you’ll finish. It will keep you organized and accountable, so you can avoid procrastinating or avoidable speed bumps that might slow you down. It also helps you compartmentalize the many items on your to-do list so you don’t stress out about how much you need to accomplish.

When creating your schedule, especially during the research stage when there is no formal class schedule for you to adhere to, focus on deliverables. Set a date when you will submit a section of your thesis to your advisor, or when you will complete your literature review. Setting goals and clear outcomes will keep you on track and focused.

#7 Take initiative and be independent

The last tip to help you get your PhD done faster is to take initiative. Remember that a PhD is a largely independent endeavor. You’ll have the support of a committee or advisor, but you can’t rely on them to do the work for you or put everything on hold if they aren’t available when you need them. Be flexible and adaptable so you can keep working and moving forward, even if your schedule gets interrupted or needs to change to suit your situation.

It's also important to take the initiative in your learning. Take advantage of opportunities for growth, networking, and gaining experience where you can. Get the most out of your PhD program and use your experiences to fuel your end goal of completing your thesis.

On average, it takes 4-5 years to get a PhD. There are a few factors that can influence the time it takes to complete your PhD, from program length and structure to what country you are earning your PhD in, to your own personal work ethic and schedule.

PhD programs in the US are on average 4-6 years. In Canada and the UK, they are usually 3-5 years long. Part-time PhD programs may take up to 7-8 years to complete. Direct-entry PhD programs and dual master’s and PhD programs are typically 5 years long. If you’re enrolling in an online, hybrid or accelerated PhD program, the timeline is usually 2-3 years, but there are some extremely short 1-year PhD programs offered online for specific disciplines.

Yes, you can finish your PhD before the “normal” timeline. For example, if you complete your coursework early, if you finish writing your thesis faster than average and get it approved, or if you otherwise complete all your PhD program requirements before the anticipated finish date. 

Yes, there are online PhDs available for certain fields and disciplines. These typically range from 2-3 years, although there are some traditional 4-year PhD programs offered online. There are also some “accelerated” online PhDs which last 12-18 months.

A PhD program is not necessarily shorter if you first complete a master’s degree, but having gone through a master’s program can better prepare you to finish your PhD faster. Some PhD programs accept credit hours from your master’s degree towards the coursework requirements for a PhD, and if you’ve previously written a master’s thesis or completed some research during your graduate studies, this will be an advantage. Since you’ll already be familiar with the process of writing a thesis and conducting your own research, you can avoid some stumbling blocks in your PhD program that might otherwise slow down your progress.

Yes, it is possible to get a PhD without first completing a master’s degree. There are direct entry PhD programs that allow students with a bachelor’s degree to enroll, so long as they meet the admission requirements and have exceptional academic records. Some online PhDs also waive the master’s degree requirement.

Yes, it is possible to complete a traditional PhD program in a shorter amount of time than anticipate. This usually means dedicating yourself to full-time study or taking on a larger course load and increased research hours. It takes significant work, but it can be done with the right schedule and commitment.

The fastest PhD programs are the short, 1-year accelerated programs. These programs have fewer credit hours to complete, and some have no dissertation requirement, only qualifying exams to finish. However, there are not many programs out there, and they are not available for every field of interest.

How Long Does It Take to Get a PhD?

If you aspire to rise to the top of your field, then you may have your sights set on a PhD.

Earning a doctoral degree can be a years-long process, but choosing an accelerated doctoral online program may help you complete your program more quickly.

Editorial Listing ShortCode:

Whether you’re wanting to earn one of the highest paying doctoral degrees or you have a specific one in mind, this guide can help walk you through how long it takes to complete your PhD program.

For a traditional, campus-based PhD program, the average time to finish a PhD is 8 years. Fulfilling the program’s requirements will often demand a serious investment of your time.

Even still, some people are able to finish their programs in just 3 to 6 years. Multiple factors may influence the overall length of your program.

Required Credit Hours

Many PhD programs require you to earn 120 credit hours before entering the exam and dissertation phases.

Fortunately, there are PhD programs without such high credit-hour demands. For example, at some universities, you may earn a PhD with only 60 credit hours.

Full-Time vs. Part-Time Schedule

Enrolling in a doctoral program part-time may allow you to keep up with your regular job. You’ll have to decide whether you prefer the flexibility of part-time schooling or the faster schedule of full-time studies.

Final Project Requirements

Many PhD programs end with the completion of a dissertation. This assignment may take years to complete, so PhD students often end up in the all-but-dissertation (ABD) phase for quite some time.

University Scheduling

Some schools promote their ability to help you through the PhD process faster than normal. Accelerated class schedules with eight-week online courses may speed your studies along. Focused attention from dissertation advisors may help as well.

PhD Program Components

Before you enroll in a PhD program, it’s important to know some of the basic requirements:

Prerequisites

Most schools require you to already hold a master’s degree, but some offer bachelor’s-to-PhD programs.

Length to Completion

On average, it takes eight years to earn a PhD. Even still, completing doctoral coursework and a dissertation in three to four years is not unheard of.

Topic of Interest

PhD stands for Doctor of Philosophy, but that doesn’t mean you’ll be getting a philosophy degree. Your field of study will depend on your interests and the programs that your university offers. You may tailor your doctoral focus though your choice of a dissertation topic.

Steps to Completion

You’ll take advanced classes before sitting for comprehensive exams. After passing your exams, you’ll likely begin working on a dissertation. You must defend your dissertation before finishing your program.

Doctoral studies begin with a series of classes through which you may increase your knowledge of your field of study and learn about conducting research. These are advanced classes, so they should be more in-depth than the ones you took during your undergraduate and master’s programs.

The number of courses that you need to take can vary significantly. It’s not uncommon for PhD programs to require 120 credit hours of coursework. That amounts to about 40 classes.

At other schools, the requirements are lower. Your university’s program may involve just 60 credit hours or, possibly, even fewer. A less intense course load may significantly slash your time to completion.

Your university may require you to maintain a GPA above a minimum threshold. An unsatisfactory GPA may keep you from moving on to the next step of the PhD process.

Comprehensive Examinations

Universities often require students to demonstrate their readiness for a doctoral project before advancing to the next stage of their studies. Readiness is proven through comprehensive exams , which may also be known as:

• Preliminary examinations
• Major field examinations
• General examinations

Often, comprehensive exams take the form of written or oral tests. In other situations, faculty may assess students’ readiness on the basis of a portfolio evaluation or a written paper.

Dissertation and Defense

A dissertation, also known as a graduate thesis, is a body of work that presents original research in your field. This manuscript focuses on a unique idea and includes evidence to support your thesis. During your doctoral studies, there are classes designed to help prepare you for your dissertation work.

The dissertation process may take several years. Once your manuscript is complete, you must defend it to the doctoral program faculty. After your defense, you may need to do further work on your manuscript, or the committee may decide that your dissertation is complete.

Not all programs require a dissertation. Instead, there may be an alternative doctoral project. Although both dissertations and capstone projects are rigorous, projects can sometimes be completed within a shorter time frame.

Average Time to Complete PhD by Field of Study

Students in some disciplines usually take a lot more time to finish their doctoral work than students in other fields.

If you’re studying in the following scientific fields, you may be more likely to earn your on-campus degree in seven years or less:

• Physics — average of five years
• Psychology — average of five to seven years

On the other hand, if your field of study relates more to the humanities, your on-campus degree program may take longer:

• History — average of eight years
• English — average of eight years
• Education — average of 13 years

These are the traditional figures. There are ways to finish faster.

Why Does It Take So Long to Finish a Traditional PhD?

Some schools require doctoral students to take around 40 classes, which, in a traditional on-campus setting, may take years. After completing the coursework, you must write your dissertation and defend it. The dissertation process alone might take multiple years.

Doctoral programs online may help shorten the PhD process to three or four years. Fewer credit hours may be required, and the classes may be delivered in an accelerated format.

Schools with an emphasis on quick doctoral programs may also offer dissertation advisors to efficiently guide students through that phase. Alternatively, some universities allow students to complete capstone projects that don’t take as long as dissertations.

Getting a PhD Online vs. Campus

Online education has changed students’ options for earning a PhD. These days, aspiring students may choose whether to attend classes on a college campus or online.

Traditional programs may require you to relocate to the university’s campus and attend school full-time. On average, it takes just over eight years to complete those programs. The benefits of choosing an online school instead may include:

Faster Progress

Accelerated eight-week courses may allow you to finish your course load sooner. You may complete your entire program in just three or four years.

Multiple Start Dates

Online programs often let you join throughout the year, so you don’t have to put your studies on hold until the fall semester.

Flexibility

Not being required to move to campus or come to class at set times may allow you to work your studies around your schedule.

Equal Status

Online programs are just as rigorous as on-campus ones. As long as your university is accredited, your degree will be just as valuable as one from a traditional university setting.

Cost-Savings

Finishing your doctoral studies faster may mean that you pay less tuition.

How to Finish Your PhD in Less Time

Although you can’t earn a doctoral degree overnight, you shouldn’t have to spend the majority of your working years striving toward PhD-completion. The following tips for accelerating the PhD process may help you finish your studies more quickly than the average doctoral student.

1. Use What You Already Know

Every school requires a minimum number of credit hours that you must earn in the pursuit of your degree. To help you meet this threshold, some schools will allow you to transfer in credits from other doctoral programs. Universities may also give you credit for your professional experience. Reducing your class load may save you both time and money.

2. Look for Short Classes

Accelerated course schedules are one of the best ways to speed through the degree process. Every eight weeks, you’ll begin a new set of classes. Over the course of a year, there may be five different sessions during which you can take classes.

3. Work on Your Dissertation Throughout the Program

Traditionally, dissertation work begins once the classroom portion of your studies is over. Quick doctoral programs may allow you to begin the dissertation process while you’re still taking other classes. This approach, known as an embedded dissertation, may reduce the likelihood that you’ll drop out before finishing your final project. It might also speed up your doctoral timeline.

4. Ask for Help

A lack of support can lead some doctoral students to drop out. On the other hand, having a good support system can help you push through and finish your program more quickly. Build a team of family, friends, and academic mentors who can encourage you, guide you, and lend practical help when you’re feeling overwhelmed by school.

Why Get a PhD?

You may need to earn a doctoral degree to achieve your career goals . For example, if you want to become a clinical psychologist, this level of study is essential. Many scientific and research positions require doctoral studies. University faculty typically need to hold terminal degrees as well.

Even if a doctorate is not a requirement for your desired line of work, it may help you achieve greater success. You might be granted higher levels of responsibility, and you may earn more money. In some fields, those who hold PhDs make around 20% more than those with master’s degrees, according to the Bureau of Labor Statistics .

Do You Have to Have a Master’s Degree to Get a PhD?

Many schools consider a master’s degree an essential prerequisite for PhD admission. If you don’t already have a master’s degree, a bachelor’s-to-doctorate program may allow you to earn a master’s and a PhD for less time and money than it would take to pursue them separately.

How Long Does It Take to Get a PhD After a Master’s?

You may be able to complete your doctoral program in three to four years if you opt for an accelerated online program. On average, traditional on-campus PhD programs take around eight years to complete.

How Hard Is It to Finish a PhD?

Doctoral studies are challenging. That shouldn’t come as a surprise; if doctorates were easy to acquire, nearly every college graduate would end up with a PhD behind his or her name.

Approximately 50% of students who begin a PhD program don’t end up finishing. Many quit within two years of starting. Another large portion gives up upon reaching the dissertation phase.

Although all PhD programs are challenging, the flexible nature of online programs may help you find success. Choosing a doctoral track that doesn’t require a dissertation may help as well.

What Is the Easiest PhD to Get?

All PhD programs are demanding, but you might have an easier time if you select a program that aligns with your interests and your career goals. The flexibility of online study may help your doctoral program seem less burdensome. In addition, capstone projects are sometimes easier than writing dissertations.

If earning a doctoral degree in a short time frame is important to you, then consider the many potential benefits that online programs have to offer. Within just a few years, you may be able to place the letters “PhD” at the end of your name.

UK and Europe students decide on their PhD thesis subject area before they apply . While taking classes at a graduate level, prospective PhD students in the USA spend up to a year or two deciding on their specific research subject. It is normal to apply for up to six institutions for a PhD in the USA, and students apply to each institution separately as there is no central organisation. 

Students in the UK and Europe are expected to apply with an understanding of the subject already, usually in the form of a masters degree, and be ready to start studying at the PhD level straight away. In the USA it is expected that students do not have an in-depth understanding of their subject as they usually only have an undergraduate degree when they apply. 

When should I start applying for a PhD in the USA?

Deadlines for applications to PhD programs in the USA tend to be between December and February, and institutions should let you know about your application by April. Most US institutions recommend that you apply as far in advance as you possibly can to give them, and you, plenty of time to make arrangements. 

Universities in the USA do not require a masters for you to apply as well. Because of the graduate programs in the US, you will receive your masters degree once you have completed your coursework stage. This practice combines the masters and PhD into one.

It varies from institution to institution, but international students in the USA are required to have a TOEFL score of about 90.

Funding your PhD in USA

PhD students are very likely to receive financial support in the form of PhD scholarships ; some USA PhD students also receive PhD studentships .

Making your PhD application in plenty of time allows you more time to apply for and arrange your PhD funding. Many students find that funding can cover much, or all, of the cost of their PhD studies in the USA, which ranges between $28,000 and $40,000. Deadlines for funding applications can be as early as December before starting your studies in the Autumn/Fall. 

There are two types of PhD funding: fully funded, which pays for the student's graduate school tuition fees, accommodation, and living expenses, or partially funded, which pays for the student's tuition only partially or fully.

Can a PhD be fully funded?

Yes, many top universities in the USA offer fully funded PhD programs for eligible students. This funding pays for the student's graduate school tuition fees, accommodation and living expenses. Partially funded PhDs only cover the student's tuition in part or in full.

Some PhD students will receive a stipend from their institution with an assistantship position, but this varies between institutions and between departments within institutions. Other students can find funding from both their own and the American government, and there are plenty of American government schemes like The Fulbright Program that offer funds.

This ambition has led you to consider pursuing a PhD, a journey that represents the highest echelon of academic achievement.

But before you dive into the world of research, scholarly papers, and intellectual debates, there’s a critical question that looms large—how long will it take to earn that coveted Doctor of Philosophy degree? The answer isn’t as straightforward as one might hope. It’s a complex equation, influenced by various factors, and it’s a puzzle that many aspiring doctoral students grapple with.

Understanding the time commitment of a PhD is not merely a matter of academic curiosity. It’s a pivotal factor that can shape your life’s trajectory in significant ways. This introduction explores the intricacies of a PhD journey, from the initial spark of academic passion to the profound understanding of what it takes, in terms of time, to turn that passion into a doctoral reality.

Earning a PhD is a highly individualized journey, and its duration can vary significantly from person to person. This section will delve into the myriad factors that play a role in determining the length of a PhD program. It’s important to understand that the timeline is not a fixed number of years but is influenced by various variables. Here are some key factors:

• Field of Study: The nature of your research area has a significant impact. Some fields, such as the natural sciences or engineering, might require extensive laboratory work and data collection, which can lengthen the Ph.D. process. In contrast, fields like humanities or social sciences might involve less time-intensive data collection but demand extensive writing and analysis.
• Country: The country in which you pursue your PhD can greatly affect the duration. Different countries have different academic systems and expectations. For example, in the United States, it’s common for PhD programs to last longer compared to some European countries where they tend to be shorter and more structured.
• Research Focus: The specific focus of your research project can influence the time required. If your research involves cutting-edge, complex topics, it might take longer to gather and analyze data or develop new methodologies. On the other hand, a well-defined and less ambitious research question could lead to a quicker completion.

Let’s take a closer look at the intricate web of factors that influence the duration of a PhD program. Imagine two students, both embarking on their journeys to earn a PhD, but in different fields.

Student A is pursuing a PhD in physics. This field often involves conducting elaborate experiments, gathering extensive data, and fine-tuning intricate instruments. The pursuit of new discoveries in the realm of physics can be time-consuming, and the PhD program might extend to several years to complete all the necessary research.

Student B, on the other hand, is studying literature and cultural studies. Their research involves in-depth analysis of existing texts, interpretations, and critical theories. While the reading and writing process is extensive, it may not require as many years as Student A’s experimental work.

Now, consider these students in the context of the country in which they are pursuing their PhD Student A is in the United States, where doctoral programs typically span several years. Meanwhile, Student B is in a European country known for its structured and shorter Ph.D. programs.

Lastly, let’s factor in research focus. Student A’s project is ambitious, attempting to uncover the mysteries of the universe, which can be a time-intensive endeavor. In contrast, Student B’s research question is more narrowly defined, making the path to completion relatively shorter.

These examples illustrate how the combination of field of study, country, and research focus can significantly influence the duration of a PhD program.

Understanding the average duration of a PhD program can help prospective students set realistic expectations. This section will provide an overview of the typical timeframes for completing a PhD.

• Average Duration: On a global scale, a PhD program often spans between 5 to 7 years. This period includes coursework, research, and the writing and defense of a dissertation. However, it’s important to note that this duration can vary significantly. In the United States , for instance, it’s common for PhD programs to take longer, often 5 to 7 years or even more, due to the inclusion of coursework and comprehensive exams. In contrast, in some European countries, PhD programs are designed to be shorter, typically around 3 to 4 years, as they are research-focused with less emphasis on coursework.
• Variations by Field: The average duration can also differ based on the field of study. Fields requiring extensive data collection, such as the natural sciences or engineering, might take longer, while fields like humanities or social sciences with more writing and analysis may have shorter timeframes.

When it comes to the average duration of a PhD program, the common adage ‘it’s a marathon, not a sprint’ certainly applies. The typical journey to a PhD is a long and demanding one, taking aspiring scholars through a series of rigorous academic challenges.

Globally, a PhD program often spans between 5 to 7 years. This period includes the initial coursework phase, where students delve deep into the theoretical foundations of their field. This is followed by a substantial research phase, during which they gather data, conduct experiments, or engage in extensive fieldwork. Finally, the culmination of this journey is the completion and defense of a dissertation, a written document that contributes new knowledge to their field.

However, it’s crucial to remember that these timeframes are general averages and can vary significantly based on various factors. In the United States, for example, it’s quite common for PhD programs to extend to the longer end of the spectrum, taking 5 to 7 years or even more to complete. This is because American PhD programs often include a significant coursework component and comprehensive exams before the dissertation phase begins.

On the other hand, in some European countries, PhD programs are designed to be more streamlined and research-focused. They typically take around 3 to 4 years to complete, reflecting a shorter timeframe. This structure is influenced by the belief that students entering PhD programs are already well-prepared in their chosen field, and the primary focus is on conducting independent research.

Additionally, the duration can also vary based on the specific field of study. Fields that require extensive data collection or experimental work, such as the natural sciences or engineering, tend to have longer PhD programs. In contrast, fields like humanities or social sciences, where research involves more reading, writing, and analysis, may have shorter timeframes.

Keep in mind that these are general guidelines, and individual PhD experiences can deviate from the average.

Ph.D. program durations can vary significantly between countries due to differences in educational systems and academic traditions. This section will explore how and why PhD programs’ lengths differ by country.

• United States: In the United States, PhD programs are known for their comprehensive structure. They often include a combination of coursework, comprehensive exams, and dissertation research. This makes them typically longer, often spanning 5 to 7 years or more.
• European Countries: In many European countries, PhD programs are more streamlined and research-focused. They tend to be shorter, typically around 3 to 4 years. European programs often assume that students have a strong foundation in their field when they enter the Ph.D. phase.
• Other Countries: The duration of PhD programs can also vary in other parts of the world. For instance, in some Asian countries, the length of a PhD program can be influenced by the nature of the research and the institution’s specific requirements.

When contemplating the pursuit of a Ph.D., it’s important to recognize that the path you tread can be markedly different depending on the country in which you choose to study. The world’s countries have diverse academic systems and traditions, and these intricacies play a significant role in shaping the duration of PhD programs.

Consider the United States, a country renowned for its rigorous academic programs. Here, PhD programs are known for their comprehensive nature. Students often undergo a period of intensive coursework, followed by comprehensive exams to assess their knowledge. This is in addition to the research phase, which involves conducting experiments, gathering data, or delving deep into the chosen area of study. As a result, PhD programs in the United States are often among the longer ones, frequently taking 5 to 7 years or even more to complete.

In contrast, many European countries have adopted a more streamlined approach to PhD programs. These programs tend to be research-focused from the outset, with the assumption that students entering PhD programs already possess a strong foundation in their chosen field. The result is a shorter program, typically spanning around 3 to 4 years. In countries like the United Kingdom, the Netherlands, and Denmark, students can transition directly into their research, which contributes to the shorter duration.

Outside of the United States and Europe, PhD program lengths can vary significantly depending on the country’s educational system and specific institutional requirements. For instance, in certain Asian countries, PhD programs might also be research-intensive and shorter in duration, or they might extend to accommodate the complexity of the research involved.

It’s important to understand these country-specific variations when considering a PhD program, as they can have a profound impact on the length of your academic journey.

A Ph.D. program is not a single, continuous journey but is typically divided into distinct stages. This section will provide an overview of the common stages of a PhD program, which include coursework, research, and dissertation writing.

• Coursework: The journey usually starts with a coursework phase, where students dive deep into the theoretical foundations of their field. During this stage, students take classes and seminars to build a strong academic foundation. The duration of this stage varies by country and field but generally lasts from 1 to 2 years.
• Comprehensive Exams: In some countries, notably the United States, students are required to pass comprehensive exams to demonstrate their mastery of their field. This stage can add a few months to a couple of years to the timeline.
• Research Phase: After coursework and exams, students transition into the research phase, which is the heart of a Ph.D. program. This phase involves conducting original research, experiments, fieldwork, or in-depth analysis, depending on the field of study. It can last several years, usually 3 to 5 years or more, depending on the complexity of the research and the progress made.
• Dissertation Writing: The final stage involves writing the PhD dissertation, a comprehensive document that presents the research findings and contributes to the academic field. The duration of this stage varies but often takes at least a year.

A PhD program is akin to an academic epic, with distinct stages that collectively make up the hero’s journey. As an aspiring doctoral candidate, it’s essential to understand the key stages you’ll encounter along the way.

The odyssey begins with coursework. During this initial stage, students embark on a voyage into the theoretical underpinnings of their chosen field. They attend classes, seminars, and lectures to deepen their understanding. This coursework phase, which can last anywhere from 1 to 2 years, serves as the foundation upon which the rest of the journey is built.

In some countries, particularly the United States, there’s another formidable challenge—comprehensive exams. These exams test the student’s mastery of the field’s core concepts and are often required before moving on to the next stage. Comprehensive exams can extend the journey by several months to a couple of years.

The heart of the PhD journey lies in the research phase. This is where students immerse themselves in original research, which could entail conducting experiments, gathering data, or engaging in extensive fieldwork, depending on their field of study. The duration of this stage is the most variable, spanning approximately 3 to 5 years or even longer, depending on the complexity of the research and the progress made.

Lastly, the culmination of the PhD adventure is the dissertation writing stage. Here, students craft a comprehensive document that presents their research findings, methodology, and contributions to the academic field. This final stage can vary in length but often takes at least a year to complete.

These stages collectively shape the journey towards a PhD, and understanding them is vital for anyone embarking on this academic odyssey.

While earning a Ph.D. is a significant commitment, there are strategies to expedite the process. This section will discuss strategies and approaches that can help shorten the timeline of your PhD journey .

The knowledge, skills, and methodologies you’ve acquired can significantly expedite your research and data collection, potentially helping you complete your PhD in less time.

These strategies, when applied thoughtfully, can make the road to a PhD a bit smoother and shorter, ultimately allowing students to achieve their academic goals more efficiently.

While shortening the Ph.D. journey is a common goal, there are situations that can unexpectedly lengthen the timeline. This section will discuss various reasons a Ph.D. might take longer than expected, including research challenges and personal circumstances.

• Complex Research Challenges: Research is at the core of a Ph.D., and sometimes, research challenges can extend the timeline. For instance, unexpected technical issues, data collection difficulties, or unanticipated roadblocks in the research process can delay progress. Dealing with these complexities often requires additional time and problem-solving efforts.
• Scope of the Project: Sometimes, students may underestimate the scope of their research project. If the research topic turns out to be more extensive or multifaceted than initially anticipated, it can lead to a longer journey. Expanding the research scope can also be driven by a desire to make a more substantial contribution to the field.
• Personal Circumstances: Personal circumstances can also play a significant role in lengthening the timeline. Life events, such as family responsibilities, health issues, or other personal challenges, can disrupt the academic trajectory and extend the Ph.D. program.

While aspiring doctoral candidates often set out with the goal of completing their PhD as efficiently as possible, it’s important to acknowledge that unexpected factors can sometimes extend the journey. Let’s delve into some of the reasons a PhD might take longer than initially expected:

One of the most common factors is research challenges. Research is the backbone of a Ph.D., and it’s not uncommon to encounter unanticipated complexities along the way. For instance, imagine a Ph.D. student in the field of environmental science who encounters technical issues with specialized equipment required for data collection. These unexpected hurdles can require additional time and effort to resolve, extending the research phase.

Another factor that can elongate the timeline is the scope of the project. Sometimes, students may begin their research with a particular understanding of the project’s scale, only to discover that the topic is more extensive or multifaceted than initially thought. This realization can lead to an expansion of the research scope, often driven by the desire to make a more significant and impactful contribution to the field. While noble in its intent, this expansion can result in a longer and more extensive research phase.

Personal circumstances can also have a profound impact. Life doesn’t always adhere to the academic calendar, and various personal challenges can disrupt the PhD journey. These challenges can include family responsibilities, health issues, or other unforeseen life events. Balancing these personal circumstances with academic commitments can sometimes lead to a longer timeline for completing a PhD.

It’s crucial to recognize that while we often have our sights set on a timely completion, the PhD journey can be influenced by a myriad of unforeseen factors. Overcoming these challenges is a testament to resilience and dedication in the pursuit of knowledge.

To sum it up, figuring out how long a Ph.D. takes is like solving a puzzle. In the U.S., it’s a bit like a long journey, taking about 5 to 7 years, while in Europe, it’s more like a focused sprint, finishing in about 3 to 4 years.

We also learned about the different stages of a Ph.D., from classes to big research and a huge paper called a dissertation. Some folks speed up their Ph.D. by managing time well, picking a good advisor, or using past research experience. But unexpected stuff, like tough research problems or personal things, can make the Ph.D. journey longer.

In Ph.D. land, time is like money you spend to learn and get smart. Whether someone is thinking about starting a Ph.D. or already on the journey, it’s their special story. Enjoy the good parts, handle the tough bits, and feel proud of becoming a real expert, adding to what everyone knows together.

• How Long Does A PhD Take?
• Doing a PhD

Sometimes, just knowing how long a PhD takes can be enough to sway your decision on whether a research degree is for you. So with that in mind, exactly how long does a PhD take?

In the UK, a full-time PhD takes 3 to 4 years to finish whilst a part-time PhD takes twice as long at 6 to 7 years. Alongside these average durations, there are time limits on how long you can be enrolled on to a PhD programme. To discover these limits, the factors which most influence doctoral degree durations and how the UK durations compare to international PhDs, continue reading on.

How Long Does It Take to Get a Full-time PhD?

In the UK, a full-time PhD will typically take you 3 to 4 years. You will usually spend the first three years on the technical aspects of your doctorate. This includes undertaking independent research, designing your research methodology and collecting and analysing data. You will then spend an additional academic year on writing up your PhD thesis and sitting your viva.

How Long Does It Take to Get a Part-time PhD?

In the UK, a part-time PhD will typically take you 6 to 7 years; twice as long as doing a full-time PhD. The reason for this is that as a part-time PhD student, you would dedicate around 20 hours per week to your PhD as opposed to the typical 40 hours full-time students would put into their subject.

How Long Does a Distance Learning PhD Take?

Similarly, distance learning PhD’s take an average of 6 to 7 years to complete. This is because the vast majority of students who undertake a distance learning PhD do so because they can’t relocate closer to the university. Although these commitments will differ, they often mean the student isn’t able to dedicate 40 hours per week to their studies.

Students in STEM disciplines will often take longer to finish a distance learning doctorate degree than those in non-STEM disciplines. This because the progress of a STEM PhD student will be limited by how often they can access a laboratory for experiment work.

How Does Funding Impact a PhD’s Duration?

In reality, the actual time it will take you to complete your PhD degree will depend on your funding situation.

If you’re receiving  funding , it will usually only cover you for 3.5 years if you’re studying full-time or for 7 years at half the stipend if you’re studying part-time. Although this could vary slightly, most PhD funding providers, e.g. Engineering and Physical Sciences Research Council (EPSRC), follow this timescale as indicated on their ‘ length of PhD studentships’ page. Because of this, most students who obtain scholarships try to complete their PhD within the timeframe of their funding so they don’t incur additional fees which they need to cover themselves.

It’s also worth noting that some funded PhD positions have additional conditions attached to them as part of their eligibility requirements. For example, they may require teaching undergraduate students, hosting laboratory sessions or attend presentations and conferences. This will be especially true if you’re on a Graduate Teaching Assistantship (GTA). Although these shouldn’t add considerable time to the length of a PhD programme, they have the potential to do so if they aren’t managed properly.

As self-funded students cover their own annual tuition fees and other associated costs, how long they’ll spend to complete their PhD project will largely depend on their own personal financial situation. Because of this, most self-funded PhD students find it best to complete their PhD study in the shortest time-frame they can manage.

Are There Deadlines?

Yes – unfortunately, all good things must come to an end! Within the UK, the deadline for your PhD is defined as the last date which you must submit your final thesis by. This date is set by your university’s overall regulations and varies depending on the arrangements of your PhD, e.g. whether it’s full or part time. In the vast majority of cases, the adopted deadlines are four years for full-time PhDs and seven years for part-time PhDs from the date you were officially registered onto your programme, as shown below from the University of Leicester’s registration guidance page .

This time-frame may vary from university to university. For example, the University of Sheffield adopts an additional year for part-time PhDs as shown below.

Can I Complete It Faster?

Although it’s possible to complete a full-time PhD in under 3 years, it’s a significant feat that’s rarely heard of. When these feats occur, they’re usually where the doctoral student already has extensive knowledge and experience in their field before undertaking their PhD.

Whilst it’s possible to complete a part-time PhD in under 6 years, it largely depends on your commitments outside your studies. For example, if you have a part-time career alongside your PhD, it’s unlikely that you’ll be able to commit the additional hours required to complete your doctorate a year faster.

However, if instead of a steady part-time job you take on occasional work as a freelancer, you’ll be able to set aside many more hours towards your doctoral degree.

Will Having only A Bachelor’s Degree or Being an International Student Limit My Rate of Progression?

Not at all. While there are benefits to having a Master’s degree such as an additional year of learning and greater research experience due to your fourth-year dissertation project, this doesn’t mean not having one would limit you. A PhD is very different to both Bachelor and Master degrees due to being heavily research-based, therefore, both types of students will have just as much to learn on their way to completing their doctorate.

Similarly, whether you’re an international student will bear no influence on the duration of your PhD.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How Does This Compare to the Duration of EU and US PhDs?

PhD hosted by universities within the EU, such as those in France, Norway and Spain, have the same programme structure as those within the UK. As a result, there are no noticeable differences in the time to complete a doctorate between UK and EU institutions.

However, this is not the case in the US. Compared to PhDs conducted within the UK or EU, PhDs conducted within the US take considerably longer to obtain. According to a  2017 study conducted by the National Science Foundation, a US government agency which supports research and higher education, the average time to get a PhD within the US is 5.8 years. Besides this, the average completion time can further increase depending on the disciplines. For example, they found doctorates within the humanities and arts to take an average of 7.1 years to achieve.

The primary reason for this difference is the way PhD degrees are structured within the United States. As mentioned previously, PhDs conducted within UK and EU universities are essentially broken into two sections – one covering the analytical aspects and the other covering the writing up aspects. However, within the US, doctorate programmes comprise additional sections. PhD students are first required to undertake 2 to 3 years of courses, which cover a broad range of topics related to their schools’ discipline. This is then followed by coursework and several examinations, which only once passed can the PhD candidate then start working on their research project and dissertation.

How Long Does It Take to Get a Ph.D. Degree?

Earning a Ph.D. from a U.S. grad school typically requires nearly six years, federal statistics show.

(CAIAIMAGE/TOM MERTON/GETTY IMAGES)

A Ph.D. is most appropriate for someone who is a “lifelong learner.” 

Students who have excelled within a specific academic discipline and who have a strong interest in that field may choose to pursue a Ph.D. degree. However, Ph.D. degree-holders urge prospective students to think carefully about whether they truly want or need a doctoral degree, since Ph.D. programs last for multiple years.

According to the Survey of Earned Doctorates, a census of recent research doctorate recipients who earned their degree from U.S. institutions, the median amount of time it took individuals who received their doctorates in 2017 to complete their program was 5.8 years. However, there are many types of programs that typically take longer than six years to complete, such as humanities and arts doctorates, where the median time for individuals to earn their degree was 7.1 years, according to the survey.

Some Ph.D. candidates begin doctoral programs after they have already obtained master’s degrees, which means the time spent in grad school is a combination of the time spent pursuing a master’s and the years invested in a doctorate. In order to receive a Ph.D. degree, a student must produce and successfully defend an original academic dissertation, which must be approved by a dissertation committtee. Writing and defending a dissertation is so difficult that many Ph.D. students drop out of their Ph.D. programs having done most of the work necessary for degree without completing the dissertation component. These Ph.D. program dropouts often use the phrase “ all but dissertation ” or the abbreviation “ABD” on their resumes.

According to a comprehensive study of  Ph.D. completion rates  published by The Council of Graduate Schools in 2008, only 56.6% of people who begin Ph.D. programs earn Ph.D. degrees.

Ian Curtis, a founding partner with H&C Education, an educational and admissions consulting firm, who is pursuing a Ph.D. degree in French at Yale University , says there are several steps involved in the process of obtaining a Ph.D. Students typically need to fulfill course requirements and pass comprehensive exams, Curtis warns. “Once these obligations have been completed, how long it takes you to write your dissertation depends on who you are, how you work, what field you’re in and what other responsibilities you have in life,” he wrote in an email. Though some Ph.D. students can write a dissertation in a single year, that is rare, and the dissertation writing process may last for several years, Curtis says.

[ READ: What Is a Doctorate or a Doctoral Degree?  ]

Curtis adds that the level of support a Ph.D. student receives from an academic advisor or faculty mentor can be a key factor in determining the length of time it takes to complete a Ph.D. program. “Before you decide to enroll at a specific program, you’ll want to meet your future advisor,” Curtis advises. “Also, reach out to his or her current and former students to get a sense of what he or she is like to work with.”

Curtis also notes that if there is a gap between the amount of time it takes to complete a Ph.D. and the amount of time a student’s funding lasts, this can slow down the Ph.D. completion process. “Keep in mind that if you run out of funding at some point during your doctorate, you will need to find paid work, and this will leave you even less time to focus on writing your dissertation,” he says. “If one of the programs you’re looking at has a record of significantly longer – or shorter – times to competition, this is good information to take into consideration.”

Pierre Huguet, the CEO and co-founder of H&C Education, says prospective Ph.D. students should be aware that a Ph.D. is designed to prepare a person for a career as a scholar. “Most of the jobs available to Ph.D. students upon graduation are academic in nature and directly related to their fields of study: professor, researcher, etc.,” Huguet wrote in an email. “The truth is that more specialization can mean fewer job opportunities. Before starting a Ph.D., students should be sure that they want to pursue a career in academia, or in research. If not, they should make time during the Ph.D. to show recruiters that they’ve traveled beyond their labs and libraries to gain some professional hands-on experience.”

Jack Appleman, a business writing instructor, published author and Ph.D. candidate focusing on organizational communication with the  University at Albany—SUNY , says Ph.D. programs require a level of commitment and focus that goes beyond what is necessary for a typical corporate job. A program with flexible course requirements that allow a student to customize his or her curriculum based on academic interests and personal obligations is ideal, he says.

[ READ: Ph.D. Programs Get a Lot More Practical.  ]

Joan Kee, a professor at the University of Michigan  with the university’s history of art department, says that the length of time required for a Ph.D. varies widely depending on what subject the Ph.D. focuses on. “Ph.D. program length is very discipline and even field-specific; for example, you can and are expected to finish a Ph.D, in economics in under five years, but that would be impossible in art history (or most of the humanities),” she wrote in an email.

Jean Marie Carey, who earned her Ph.D. degree in art history and German from the  University of Otago  in New Zealand, encourages prospective Ph.D. students to check whether their potential Ph.D. program has published a timeline of how long it takes a Ph.D. student to complete their program. She says it is also prudent to speak with Ph.D. graduates of the school and ask about their experience.

Bennett urges prospective Ph.D. students to visit the campuses of their target graduate programs since a Ph.D. program takes so much time that it is important to find a school that feels comfortable. She adds that aspiring Ph.D. students who prefer a collaborative learning environment should be wary of graduate programs that have a cut-throat and competitive atmosphere, since such students may not thrive in that type of setting.

[ READ: 4 Fields Where Doctorates Lead to Jobs.  ]

Alumni of Ph.D. programs note that the process of obtaining a Ph.D. is arduous, regardless of the type of Ph.D. program. “A Ph.D. is a long commitment of your time, energy and financial resources, so it’ll be easier on you if you are passionate about research,” says Grace Lee, who has a Ph.D. in neuroscience and is the founder and CEO of Mastery Insights, an education and career coaching company, and the host of the Career Revisionist podcast.

“A Ph.D. isn’t about rehashing years of knowledge that is already out there, but rather it is about your ability to generate new knowledge. Your intellectual masterpiece (which is your dissertation) takes a lot of time, intellectual creativity and innovation to put together, so you have to be truly passionate about that,” Lee says.

Erin Skelly, a graduate admissions counselor at the IvyWise admissions consulting firm, says when a Ph.D. students struggles to complete his or her Ph.D. degree, it may have more to do with the student’s academic interests or personal circumstances than his or her program.

“The time to complete a Ph.D. can depend on a number of variables, but the specific discipline or school would only account for a year or two’s difference,” she wrote in an email. “When a student takes significantly longer to complete a Ph.D. (degree), it’s usually related to the student’s coursework and research – they need to take additional coursework to complete their comprehensive exams; they change the focus of their program or dissertation, requiring extra coursework or research; or their research doesn’t yield the results they hoped for, and they need to generate a new theory and conduct more research.”

Skelly warns that the average completion time of a Ph.D. program may be misleading in some cases, if the average is skewed based on one or two outliers. She suggests that instead of focusing on the duration of a particular Ph.D. program, prospective students should investigate the program’s attritition and graduation rates.

“It is worthwhile to look at the program requirements and the school’s proposed timeline for completion, and meet current students to get their input on how realistic these expectations for completion are,” Skelly says. “That can give you an honest idea of how long it will really take to complete the program.”

How Long Does it Take for PhD in USA?

How Long Does it Take for PhD

Embarking on the academic journey towards a PhD is akin to setting sail on uncharted waters, where the duration of the expedition is as variable as the vastness of the scholarly ocean. As an individual who has successfully navigated the intricate channels of doctoral studies , I can attest that the question of how long it takes to earn a PhD does not succumb to a universal answer.

Average Duration

The journey towards a PhD in the United States typically takes about 5.5 years, with 5 years being the ideal goal.

On average, the pursuit of a Ph.D. in the United States spans around 5.5 years, with the golden standard being a five-year trajectory. In recent times, a growing number of scholars in various fields find themselves investing six years to achieve this academic milestone.

Variability

Some scholars may take up to 6 years, while a few exceptionally diligent individuals may complete it in 4 years. However, caution is advised with shorter timelines.

There exist a few exceptional cases where individuals of extraordinary diligence manage to conclude their doctoral journey in a commendable four years. However, it is crucial to approach such an ambitious timeline with caution, as it may not always be advisable or feasible.

Real-life Stories

Examples include a Physics PhD candidate in Santa Barbara reaching a 9-year mark and an English PhD candidate in her 8th year, facing challenges due to limited job prospects in her field.

Insightful Perspective

A PhD takes as long as it takes. Rushing is not advised; the focus should be on having solid research and a clear vision for the future.

Individual Journey

The duration varies based on the depth and complexity of the research. It’s not a race against time but a profound exploration into the realms of knowledge.

Story of a PhD Researcher

Anecdotes from the academic terrain reveal instances that border on the surreal. I recall a Physics PhD candidate in Santa Barbara, California, who found himself on the precipice of a ninth year in pursuit of his doctorate. While this might sound like a surreal scenario, it serves as a reminder that the Ph.D. odyssey is as diverse as the landscapes it traverses.

Similarly, an English Ph.D. candidate, already eight years into her scholarly expedition, faced a unique set of challenges. The confluence of her extended doctoral journey and the limited job prospects in her field painted a challenging picture, resembling more of a nightmare than a dream.

In reflecting on these varied timelines, one of my esteemed professors shared a profound insight: a Ph.D. takes as long as it takes. Rushing through the process for the sake of a premature conclusion is rarely beneficial.

The key lies in ensuring that the research is in a robust state and that the dissertation is a testament to the scholarly rigor that defines a PhD candidate. Moreover, a clear vision of the research trajectory for the next decade or more is a critical component of a successful PhD journey.

In conclusion, the individual researcher uniquely tailors the duration of a Ph.D. journey. The depth and complexity of the undertaken research dictate its organic unfolding, rather than a predetermined timeline binding it.

As aspiring scholars embark on their academic odyssey, the wisdom lies in embracing the ebb and flow of this intellectual voyage, understanding that a PhD is not a race against time but a profound exploration into the realms of knowledge.

Study PHD in USA | Eligibility, Application Process (2022 Guide)

Accessibility

  PhD student in USA does not require  to focus immediately on dissertation proposal but will  have the time to first develop a more detailed understanding of your subject as the basis for your own research. That is why PHD in USA are longer as compared to UK.

World-leading universities and research

Rankings aren’t everything, but the upper reaches of global league tables continue to be dominated by US institutions. As there is a substantial investment in research output and expertise.

International community

  Whatever and wherever you study you’ll be welcomed as part of a diverse academic community .

Innovation :

America was the second country (after Germany) to adopt the modern PhD degree and its own structured approach to doctoral training is now influencing PhD study in the UK and Europe.

Breadth of opportunity :

With 50 states, six time zones and thousands of higher education providers you will find a huge opportunity after your PHD

NOTE : The fact that matters is, one needs to look for the quality and the number of research paper’s that are being published in the top journals in the industry country wise. 

In most cases the US is the best place to do your PHD. But do your research and find which country produces the best research work and go there for better learning and growing experience.

1.2) 5 Reasons Why one should pursue a PHD in the USA rather than a Master's/ Bachelors?

PHD is free/Cheap:

When it comes to Bachelors and Master’s, there are quite some options for us to get funding from or get scholarships. But the problem is that not a lot of students get full scholarships and they would be forced to pay the remaining tuition fees and alot of other costs that comes along while living in the USA.

We are all aware that education in the US is more on the expensive side and a lot of students find a way to pull it off with as many part time jobs as possible. But this affects their schedule and routine and drains their mental energy and consumes alot of their study time

Whereas PHD in the USA is a different story. The programs are fully funded and you even get paid to study there and there is no need to pay the tuition fee.

Fee waivers, assistantships and stipends are guaranteed in a PHD program and the stipends are quite high for PHD students in the US when compared to any other country. So for doing PHD, US can be considered the best place!

PHD saves us from the worst possible outcome:

When it comes to pursuing a degree abroad, what is the worst possible outcome that could come out of it?

We finish the degree there and yet we get shipped back to our home country with a bunch of huge educational loans and we have to find a job here with a currency that much lower in value and work hard to pay back all the educational loans

Whereas a PHD student wouldn’t have to be too scared about this fact since their educational expenses are usually taken care of via stipends and assistantships and other funding sources. And even if one doesn’t secure a job there, they could always get well paying great jobs back in India or any developing country which has so many universities.

Networking:

“ You are the average of 5 people that you hang around with the most”

Imagine getting enrolled into a good university in the US for PHD. What would be the quality of people there? 

While doing your bachelor’s degree, one would be surrounded by all kinds of people from all around the world with different lifestyles and mindsets and there you could find alot of people who tend to fool around and be less focused or live by ideologies that you might totally disagree with. 

Whereas when it comes to master’s degree, the quality of the crowd increases tremendously and with PHD, only the most motivated, interested and focused people get here. So you could learn and grow as a community while doing your PHD. Another important fact is, everyone doing a PHD is there by their own choice which makes them a group of highly interested and talented people with whom you would be spending most of your time with.

Friendships with Mentors:

“ PHD students are like 10 year projects”

• University Mentors

In research based universities, most of the professors tend to spend a huge amount of time with the PHD students than the ones in bachelors and master’s degree programs. Bachelors students are more focused on learning the basic concepts and master’s students are usually busy with course work and won’t stay for too long in the campus.

So, one of the biggest advantages of being a PHD student in the US is that you get to spend 4-6 years researching and further continue the work for years to come and hence the mentors and the professors would be more open to building a good relationship with you and that would make way for so much of learning and growth.

Come out of it matured and better:

One of the things that a PHD student would experience is this : They start earning money a lot later than the general population. Some would even take over 30 years to get their first paycheck and when you spend your 20s learning and researching and focusing while managing the possible financial hardships that come your way, makes you financially mature.

Pros and Cons of Studying in USA

Cons of studying in the USA

• To be a student in the USA, one of the primary requirements is to write a TOEFL exam. This ensures that you have a good command of the English language.
• For other engineering and business studies, you will be required to write GRE, TOEFL, GMAT, SAT, etc. To be a doctor, you will be required to write a different set of entrance examinations.
• The cost of education and accommodation in the USA is higher when compared to your home country. Due to this, you may have to get a student loan.
• It is not that you will get a job if you study in any university in the USA. More of your knowledge and skills matter the most. But studying in the prestigious universities in the USA will be a feather on your cap!
• The standard of education will be initially hard to manage as you need to get used to the different curricula.
• The climatic conditions in the USA are very different and hence you should be able to adjust to them.
• The living expenses can also be higher. To manage this, you need to take up a part-time job.
• The testing in these universities can be rigorous and challenging, especially if you are a student of the most prestigious universities in the USA.

1.3) Is PHD the right choice for you?

Some students might be wondering if pursuing a PHD is a right thing for them.

It depends on the career you are in and if you are interested in research. For instance if you have a master’s in biology or in any of the languages or history, the jobs available for you would be scarce. So doing a PHD in such instances can open up a whole new alot of opportunities.

Now when it comes to research it can be categorized into two things : Discovering phenomenons in nature and inventing new stuff.

If research, discovery and inventions are something you desire, then PHD is the right choice for you.

PHD FAQ’s: Eligibility and More

2.1) intake seasons for phd programs, two teaching semester’s:.

The academic year in the USA consists of two teaching semesters: 

• August-December 
•  January-May.  

These will be when your classes and assessments take place. 

Most graduate programmes admit students in the autumn (or ‘fall’) semester because of the following reasons:

•  The scholarships and financial aids are aimed at this semester.
• There are not many financial aid opportunities as well as job opportunities available for the Spring semester

2.2) Duration of the PHD Program

The length of a PhD program in the USA is usually 4-6 years (full time ). 

Students spend 2 years on the coursework stage of their programme and 2-4 years working on their dissertation.

The minimum and the maximum durations would vary depending on the university and the field of study but traditionally a PHD program is for 5 years and there will be a year limit within which one should potentially finish their research to get their PHD.

There are students who find a way to get their PHD in 3 years as well. So expect anywhere between 4-6 years to get your PHD

Coursework : 

• Core classes (Essential )
• Elective classes (Optional )

Dissertation : 

  It’s the research proposal submitted as part of a PhD application.

2.3) AGE A FACTOR FOR PHD?

Is there any age limit for pursuing PHD or is it a good choice to start doing PHD after the age of 30? Would the age be a factor in getting jobs after?

Age is not any issue and there are people who start their PHDs even after the age of 40. So there are no age limits and in the United States they value the background and the profile and will not discriminate based on their age. So go for it if you really want to.

2.4) PHD AFTER BTECH?

Can we do a PHD right after bachelors or B.Tech Degree?

If one has decent research experience in Bachelors level itself and if it’s good quality research and if you have published papers and have some achievements to show, then yes, your chances of getting admissions into PHD would increase.

But it is generally recommended that we spend a little more time exploring the topic of interest in our master’s before jumping into a PHD program. Doing a master’s also strengthens your knowledge on the field which would be needed to be able to successfully complete your PHD.

But yes, it is totally possible to do your PHD right after bachelors. Even if the background of your profile doesn’t match with the PHD course you want to pursue, you can still get admissions if you can impress the professor you want to work with and these scenarios have happened in the past.

2.5) INTERNSHIPS DURING PHD:

Internships during PHD, Recommended or not?

The answer to this question would depend on the field you are in. 

Here’s the logic you need to look for. PHD is a degree where you are trying to become a researcher. Internships are jobs where you “work for the company and find ways to make them money”. Sometimes these two do not add up.

For instance, if you are in the Computer and software field, it’s completely alright to work in google or facebook or in some booming startups because it would help you become better in the particular field which would help with the research.

In most fields it is generally not recommended to do internships while being a PHD student since it would take your focus away from research.

What are the requirements to do a PhD in the USA?

3.1) phd in usa - requirements:.

Universities and graduate schools will set their own admissions procedures, but for most of the universities have following requirements :

• Academic transcripts  
• Research Statement
• Writing Samples
• Test Scores: General GRE And GRE Subject.

PS :   Some PhD subjects may use other graduate entry tests in place of (or in addition to) the GRE. The most common tests are:

GMAT – for DBA degrees and other programmes in Business and Management

LSAT – for JD programmes

MCAT – for MD programmes

DAT – for dental programmes

  You won’t necessarily need a Masters to apply for a PhD in the USA.  

This is because American graduate programmes effectively combine Masters and PhD study –some students actually receive a Masters at the end of their coursework stage.

If you do already have a Masters you may be able to receive credit for it and spend less time on the coursework stage of your program. This decision is made by your graduate school , who will decide how relevant your existing degree is.

Secure that dream admit

Right from lor, university shortlisting, sop, application reviews till visa counselling. galvanize has your back., phd experience.

For the first two years one would be required to take courses and will have to maintain a GPA over 3 -3.3.

Now remember there are various types of PHD programs available and what you experience might be a bit different from what’s described here but one can get a rough picture of what they will be up against.

The courses that you take in the first two years will mould you to become a better researcher and many of these courses would have projects which could potentially turn into a journal publication.

Selecting Dissertation Advisors:

Within the first year or the first two years, the student would have to analyze the professors, their areas of interest and expertise and their character to better select their own dissertation advisors.

In most cases we might have to select and come up with our own projects and research ideas whereas in some cases your dissertation advisor might already be working on the topic of your interest and in such cases you could join the research and contribute

Comprehensive/Qualifier Exam:

After completing the required set of courses in the first two years, the phd students are then required to take a comprehensive exam or a qualifier exam. Now the way in which this exam is conducted varies a lot based on the field and the university that’s conducting it.

In some cases, the students who fail this comprehensive exam would have to quit the PHD program. We do get to attempt this exam more than once and the number of re-attempts would also depend on the university conducting it. So this is an important step.

This exam most probably won’t be like the written 3 hour exams that we are used to writing. This exam would test your ability to be a successful researcher and the students might be given tough time intervals to complete research based tasks and even oral tasks.

Anyways reach out to the students in the university you are planning to take to get accurate details about what you would be facing in this comprehensive/Qualifier exam

Committee of professors and Proposal Defense:

In a proposal defense, the students have to be ready with the complete dissertation plans stating the papers and the projects that one has planned to work on. What kind of data one needs to collect, the kinds of analysis that one needs to do.

We also need to select a committee of professors and one of the professors in the committee should be outside your own department or university and schedule a meeting where you propose to them your project details

After the proposal defence, the professors would have to analyse if the research project is worthy for a PHD degree and if it is realistic and achievable

Once your proposal defence is approved, you would be working full time on your dissertation and would be expected to complete the research project proposed.

In many universities the PHD students are required and expected to teach subjects to B.Tech and Master’s students for a few semesters.

NOTE : Even within the same industry, different universities would have very different PHD programs where some universities would completely focus on quantitative research and some would focus more on a case study approach. So to get a clear idea, reach out to the PHD students in the university you are hoping to get admissions into.

PHD Experience FAQs

How many papers should we publish in our dissertation and is there a minimum requirement of any sort.

The number of papers that one can publish completely depends on the area of study and research since in certain areas one can publish over 10 papers easily whereas in other areas publishing 2 or 3 would be a great achievement.

There are students who just publish one paper in their dissertation and there are other who publish over 10. So it depends on your field of study and your dissertation advisors expectations and your capabilities.

How much stipend can one expect during their PHD in USA?

The stipends could vary from $10,000 or lower to over $50,000 depending on the university, the city and the cost of living in that area, the university and the area of study. Again to know exactly what to expect, reach out to PHD students in the university that you want to get into.

What kind of research assistantships and teaching assistantships can we expect to get during PHD for funding?

Research and teaching assistantships are for masters programs and by default traditional PHD programs in the US are fully funded. 

The point to note here is that in many universities, the PHD student has to teach and if one doesn’t do so, their stipend would not be given. So the fact is you are already working and researching for a stipend which should be enough to live through your PHD days in the US.

LIFE AFTER PHD:

Employment opportunities after phd in usa.

Here’s what could potentially happen after you finish your PHD:

Note : This is a generic question and the answer’s vary vastly based on the area of study, area of specialization and the country you live in. Anyways here’s all the possibilities that one could face after a PHD.

POST DOC POSITION :

Post doc basically means that after getting the doctorate degree one would continue do their research potentially in a university or research setting

Basically once you go from being a PHD student to a PHD graduate, you would still get to continue the journey you started during your PHD days and having a post doc position would mean it would be fully research oriented.

Usually you could get the Post doc position in the same university that you got your PHD from. There are three types of people who use a research center in an university

• Professors 
• PHD students

RESEARCH ORIENTED WORK IN THE INDUSTRY IN THE SAME AREA:

This is the dream job for any PHD student who has a love for research and publishing papers. In this job you would be researching and innovating full time publishing papers and journals and will have the funds and the space to explore and work on deeper research for the company.

JOB IN A ACADEMIC RESEARCH SETTING IN THE SAME FIELD:

With an impressive profile and a recognizable PHD from the US, there is a good chance that one could land a job in the same field that they did their PHD in. This way the work they do is directly aligned with their training 

PROFESSOR JOB IN A TEACHING FOCUSED UNIVERSITY:

Becoming a professor who could also be a researcher is a hard position to get and so many PHD graduates do take professor jobs that primarily or entirely focuses on teaching

PROFESSOR JOB IN A RESEARCH UNIVERSITY:

Only 5% of PHD graduates become assistant professors in research based universities right after graduation.

The research expectations in these colleges are way higher than the smaller universities or community colleges that are focused on teaching. Here in these universities there will be less number of classes to teach so the professor could have enough time for research.

CONTRACT BASED TEACHING POSITIONS IN UNIVERSITIES:

These are positions where you would be called a visiting professor/asst.professor. These would mostly consist of teaching work and there won’t be too much expectations or needs for research.

JOB IN A NON-ACADEMIC RESEARCH SETTING IN A DIFFERENT FIELD:

It has been seen that people who have PHD’s in mathematics, statistics and so on get jobs as data scientist and similar roles where they partly use the skills they have learnt in PHD

OPPORTUNITY IN AN UNRELATED FIELD:

There are cases where people get PHD in a certain field and yet work in a completely unrelated field where there are more job opportunities

UNEMPLOYED:

It would not be true if anyone said that after PHD there is no chance of being unemployed. This does happen in some cases.

ENTREPRENEUR:

The last and yet the best option for anyone is entrepreneurship. PHD students in general are smart and work on innovation and research and invention and sometimes they start a company based on the research work they started during the PHD journey. 

For instance, the tech giant google itself is a company that was started by a PHD student who dropped out of a university to eventually become a billionaire.

So, the outcome that one could expect from a PHD in US could vary vastly from being unemployed to becoming a professor, researcher and an entrepreneur 

OTHER FAQs ON LIFE AFTER PHD IN USA

What is the difference between a phd career and a mba career.

The main difference is that PHD is a research based degree and MBA is a management degree. But oftentimes PHD students do take management roles in companies for their sound experience and knowledge about the subject involved.

What is the main difference between being a professor in a university and being a researcher in a lab?

Being a professor in a university means there will be alot of teaching responsibilities whereas a researcher wouldn’t have to teach. But professors do have this added advantage of having the freedom to pick the topic of interest and work on it

What should students do in their master’s to get better chances of getting into a PHD program and prepare for the transition as well?

The first thing the master’s student should do is to start making friends who are currently doing PHD and try and be a part of their research. This way one can understand if they are interested in the deep level of research that a PHD student would be doing.

Is it better to have an older dissertation professor or a younger one?

First things first, your whole PHD experience relies a lot on your dissertation professor and hence it is an important factor to consider. 

Now generally students would prefer an older dissertation professor since they would have more seniority in the particular field and more experience in publishing. But if there are younger professors who are more energetic, enthusiastic and with many interesting ideas, then go with them.

Just look at that professor’s passion for research and if his personality matches with yours because having a good relationship with your advisor is the most important factor because there are cases where students even quit their university because of the bad relationships they develop with their advisors.

So it is advised that we first take courses and check if you like your professor and if you think you could potentially get along well with them and if they publish quality work.

How to deal with leaving family and mental health during your PHD in USA?

One just cannot afford to be home sick if they have big ambitions and dreams. Right? Not just about studying abroad but just about anything in life has it’s good and bad sides. We cannot avoid the bad aspect of the things in our lives

So what’s the answer? Learn to deal with it. Adapt. Shift your focus towards the mission. Grow. 

Mental Health is becoming a huge issue in today’s world and the best way to deal with it is to be open and honest about everything in your life to yourself. Maintaining a journal, meditation and self help books do come in handy.

Is it okay to take our family with us during our PHD program and will the stipend be enough to get by?

In most cases the students are either already married or they get married during the course of the PHD. The stipend itself can be enough to run a family but it is recommended that you stay in an affordable neighborhood with your partner working as well so there will be less financial burden on you.

Getting admissions for MS and PHD. What are the differences in the admissions process?

When it comes to PHD, the student would have to explain why they are interested in research and where they wish to work on and for what reason and with which professor. In addition to that the aspiring student would have to sit for either multiple interviews with the professors from the particular university or a panel interview.

Whereas getting admissions for a master’s degree generally won’t require any interviews and would be as simple as stating why you wish to pursue a MS course offered by the university.

This is because master’s programs take 1-2 years whereas when it comes to PHD the professors would have to invest a lot of time in you (Around 10 years) and hence they would access what kind of person you are and if your interests and personalities match.

How do we approach professors? And is it necessary to approach professors even before getting admissions and how do we find the professors?

Any student can find the profiles of the faculty of a university on their website and they can examine their profiles for their current topics of interests and research. It is recommended that we approach professors even before admissions to look for guidance and form a bond with them if possible and the best way to approach is to reach them via email.
