2024 Best Grad Schools in the United States for Doctorate Degrees

There are lots of options to choose from today when trying to decide which grad school to attend. College Factual was founded, in part, to help students make the decision as to what would be the best school for them. Our Best Doctor's Degree Colleges ranking is part of that endeavor.

What's on This Page: * Our Methodology

• Best Graduate Schools List

Choosing the Best Grad School for You

Our analysis looked at 691 grad schools in the United States to determine which ones have the best doctorate degree programs. Our ranking for the best grad schools is based on objective factors. We steer clear of subjective measures since they don't give a clear picture when determining how one school compares to another. The following gives more info on what goes into our ranking factors and why we consider those factors.

Higher Than Average Earnings

To determine the overall quality of a graduate school, one factor we look at is the average early-career salary of those receiving a doctorate degree from the school. Recent students who earned a doctorate degree in the United States entered the job market making an average of $75,260 while those in the top 20 schools on our list made an average of $88,513.

Taking Out Student Loans

Graduate students may also take on a lot of debt while working on their doctorate so we factor that into our rankings as well. The average amount taken out in student loans for graduates at a particular school may be crippling for those who earn less than average wages after graduation.

More Ranking Factors That Are Important

We also analyze a number of other factors in addition to average post-graduation earnings and average student debt when coming up with our yearly Best Doctorate Degree Schools ranking. On a broad level, other factors that go into our rankings include such things as the demand of the school, the student body caliber, if the school has online options, and the educational resources provided by the school.

We go into more detail on these factors on our graduate school ranking methodology page.

• PhD in USA – A Guide for 2020/21
• Finding a PhD

A PhD in USA takes approximately 5 – 6 years of full-time study and can cost between $12,000 – $45,000 per academic year. PhD programs in USA differ from that in the UK and Europe in that students must first take taught classes, coursework and exams before starting their research project.

Why Do a PhD in USA?

The United States has long had some of the most distinguished universities and advanced PhD programmes in the world. Combined with curriculum flexibility, rigorous teaching methods, vast funding opportunities, breathtaking campuses and significant career prospects, it’s no wonder that it is one of the most sought-after study destinations for research students.

In addition to comprehensive training standards, here are a few other reasons why a student may choose to undertake their PhD in the United States:

• Longer learning timeframes – A PhD in the US lasts longer than a PhD in the UK or Europe. This allows students to more confidently transition from undergraduate to postgraduate studies; more commonly referred to as ‘graduate studies’ in the US. This gives you the opportunity to learn more about your subject, research methods and academic writing in general before starting your research project.
• World-class universities – It’s no secret that some of the most well-known higher education institutions that continue to dominate global rankings are based in the United States. Although many factors go into determining whether a position is right for you, a PhD at a high-ranking American university will undeniably have many benefits, from excellent learning standards to access to innovative equipment and deep expertise.
• International network – The US has long been a popular choice among PhD students around the world. As such, the US hosts a diverse and multicultural learning environment in which many research students will quickly feel at home.
• Opportunities – With over 4,000 universities in the US, we can safely say you will have plenty of opportunities to find the ideal combination of project, supervisor and university that works for you.

Universities in USA

Universities in the United States can be divided into two types: public universities and private universities.

Public universities are financed by the state in which they are based. Because of this, public universities charge less for students from within the state and more for students from outside the state, including international students.

Private universities are not financed by their state, but by private donors, research funds and tuition fees. For this reason, private universities generally charge higher tuition fees than public universities and require all students to pay the same amount, regardless of whether they come from out-of-state or abroad.

According to the Times Higher Education World University Rankings 2021 , eight of the top ten universities in the world are located in the United States. These are:

Method of Study

The main difference between a PhD in the US and a PhD in Europe lies in the program structure. Whereas a European PhD essentially consists of a single phase lasting three to four years , an American PhD consists of three different phases, each with its own time frame.

• Phase One – The first phase lasts approximately two years and focuses on building a basic foundation for the doctoral student. This phase consists largely of taught components such as lectures, tutorials and laboratory sessions, in which the student learns more about theoretical concepts and research methods within their discipline.
• Phase Two – The second phase can be considered an assessment phase, which runs both periodically alongside and at the end of the first phase. Here, students complete coursework and take exams on the basis of the material they have covered of which they must pass in order to proceed to the third phase.
• Phase Three – The third phase lasts approximately three years and resembles the European PhD structure. During this period, the student undertakes an independent research project, including forming a research design, conducting experiments, writing a thesis (more commonly referred to in the USA as a dissertation) and sitting a viva exam.

Teaching Requirements

Besides structure, a key difference between a PhD program in the US and in Europe is the focus on teaching requirements. In the US, doctoral students are expected to lecture, lead tutorials, host laboratory sessions, mark coursework and provide office hours for undergraduate students. Although students studying in European will likely contribute to these at some point during their study, this would normally be on a voluntary basis and involve less time commitment.

Research Flexibility

Another difference is project flexibility. In Europe, students typically apply to a PhD project predetermined by a supervisor, and although there may be some scope to adapt the project, depending on the funding provider , it will usually be limited to how the project is carried out rather than what it is about. In the US, however, a student applies to become a doctoral candidate within a department rather than applying for a particular research project. This is because students are expected to decide on their thesis topic (also commonly referred to as a dissertation research topic) near the end of their first phase after they have developed a better understanding of their subject and know where their interests lie. Therefore, research students in the US generally have more flexibility and influence in the direction of their research than students in the United Kingdom or Europe.

PhD Admission Requirements in USA

PhD admission into US universities can be highly competitive, both because of the limited number of positions and the large number of annual applicants.

The eligibility requirements for a doctoral program in the USA can generally be divided into four sections:

• Grade Point Average (GPA) – in the US, a scoring system known as Grade Point Average is used to measure academic ability. A student’s GPA is calculated as a weighted score of the subjects they study during their undergraduate degree; an equivalent score is calculated by universities for international applicants. Although universities rarely set minimum GPA requirements for doctoral study, it’s worth being aware that a GPA of 3.0 is equivalent to a UK second class honours (2:1); the typical entry requirement for UK universities.
• Graduate Records Exam (GRE) – most universities will require you to take a series of examinations known as Graduate Records Exams, which are used to determine your suitability for graduate study. GREs will assess your analytical, reasoning and critical thinking skills as well as your depth of your subject.
• Student aptitude – in addition to academic ability, US universities also look for characteristics of a strong researcher. These include traits such as engaging in the subject in your own time, e.g. by attending talks and conferences, demonstrating a high degree of independence and enthusiasm, and a general passion for your subject.
• English Language Proficiency – international students whose first language is not English must sit language exams such as IELTS or TOELF to demonstrate their English language proficiency.

International students will also require a F1 student visa in order to study in the US, however, you would typically apply for this after you have secured a place into a doctorate program.

How to Apply for PhD in USA

When applying for a PhD position at a graduate school, the application process will differ between universities, however, they will all typically ask for the following:

• Academic CV – a short document summarising your educational background and current level of experience .
• Personal statement – a document which outlines why you believe you are suitable for PhD study and your passion for the subject.
• Academic transcripts – a complete breakdown of the modules and their respective marks you have taken as part of your previous/current degree.
• GRE scores – a transcript of your Graduate Records Exam results.
• Research statement – a condensed version of a research proposal outlining your general research interests, if required.
• Recommendation letters – references from several academic referees who endorse your qualities as a person, your abilities as a student and your potential as a doctoral researcher.

Application Deadlines and Fees

Since PhD programs in the United States have taught components, they commence at the same time as all other taught degrees, and therefore share the same application deadlines and start dates. This corresponds to an application period that typically begins in August and ends in February. Admission decisions are typically made in April, with successful students starting in August/September.

When you apply to a graduate school, you will be expected to pay a fee for each doctorate application to cover the school’s administrative costs for processing your application. The fee varies from university to university, but typically ranges from $50 to $100 .

Funding your PhD in USA

It’s very common for a PhD student to receive financial aid in the form of a PhD scholarship; in fact, this will be the case for the vast majority of students in the US.

PhD funding can be ‘fully funded’ covering the student’s graduate program tuition fees, accommodation and living costs, or ‘partially funded’ covering the student’s tuition fee only in part or full.

Besides funding, a graduate student can take on an assistantship, such as a graduate teaching assistant or research assistant, in which they take on a part-time salaried position at the university alongside their studies.

Due to the international and collaborate nature of American universities, there are also a number of international scholarships available, such as the Fulbright Scholarship and the AAUW International Fellowship .

PhD Duration in USA

In the US, a PhD takes approximately 5 – 6 years to complete if studying full-time, and 8 – 10 years if studying part-time.

If you already have a Master’s degree, your first phase can be shortened by one year at the discretion of the university.

Cost of a PhD in USA

The cost of a PhD program in the US can vary considerably depending on the type of university, i.e. whether it’s a public or private university, the doctoral course, i.e. whether it’s in a STEM subject such as computer science, engineering or a non-STEM subject, and whether you are a home or international student.

In general, however, the typical annual tuition fee for a PhD in the US is between $12,000 and $45,000 per academic year.

As with any doctoral degree, additional costs may include travel for collaborations, bench fees, accommodation and living expenses.

Studying a PhD in The USA - The Complete Guide

Find your perfect postgrad program search our database of 30,000 courses.

The USA is a favourable postgraduate study destination for international students due to the high standard of academic study and the wide variety of subjects. By undertaking a PhD in the USA, you will find yourself becoming an internationally recognised expert in your chosen field.

A Doctor of Philosophy (PhD) from the USA is considered the highest awarded degree in many US universities and institutes for most fields of study. For many international students, it's a dream course that offers an exciting new life chapter.

Attending Grad School for a PhD in the USA is not the same as undertaking a PhD in Europe or the UK , it can often be a different experience. However, studying abroad will improve your global cultural understanding in addition to your network of contacts for your future career. A PhD degree is often required when you apply for high-level management jobs, government expert positions, and careers like a university professor, researcher, or scientist in many fields.

There are a multitude of reasons why the United States is a fantastic choice for your PhD studies. Here’s everything you need to know about studying a PhD in the USA.

1. PhD course length

The total length of a PhD in the USA is between 4-8 years for full-time students and 8-10 years for part-time students, depending on your field of study. PhDs can be completed in 4-5 years for students with a masters degree in an appropriate subject. Students typically dedicate 1-4 years on coursework, followed by 2-4 years of dissertation work. In the USA, the academic year is divided into two teaching semesters: August to December and January to May. 

Having a longer duration for your PhD allows for greater opportunities to adjust to your course and find your footing. This enables you to concentrate on developing a more comprehensive understanding of your chosen subject at a more relaxed pace.

2. World-class universities

The US repeatedly tops the charts of worldwide ranking universities, so what better place to do your PhD studies? Although rankings shouldn’t be the main deciding factor when making your PhD choice, they're a great indicator of educational expertise.

There are many factors to consider when choosing the location for your PhD. Does the university have a high employability rate after graduation? Are you wanting to go public or private university? What kind of research facilities do they have? 

Be sure to do some research before making a decision on your perfect place of study.

3. International community

The United States is a popular choice for international students from all over the world – making it an inspirational and cosmopolitan choice for your PhD studies. No matter what your choice of academic study is, you are guaranteed to find a diverse community that welcomes students from all backgrounds. 

4. Affordable tuition fees 

There are various tuition fee options available for PhD students regardless of your budget. The American higher education system is often associated with high fees and substantial student debt, but in fact, studying at an American university isn't always expensive, and many institutions offer affordable courses. For instance, PhD costs range from $28,000 to $55,000, which shows that finding a PhD course that’s more affordable is possible. 

5. Student experience

American universities typically have vibrant campus communities with a wide range of extracurricular activities, clubs and organisations. As a student, you will have the opportunity to engage in various social, cultural and recreational activities alongside your academic studies.

6. Student Support

American universities typically provide comprehensive support services to assist you on your PhD journey. These services may include academic advising, counselling, career services, libraries, writing centres and various student organisations aimed at fostering your personal and professional development.

7. Land of opportunity

It's fair to say that student life in the USA offers something for everyone, regardless of what you're looking for from a PhD. With 50 states, six time zones, and thousands of higher-education providers, there's an opportunity waiting for every individual across the globe.

So let’s take a look at some of the key factors to consider when studying for a PhD in the USA.

Studying a PhD in the USA: top tips

Who is eligible for a phd in the usa.

To be eligible for PhD in the USA, generally students should have completed a graduate degree with a minimum GPA of 3.0, provide proof of English language proficiency, GRE scores and other supporting documents.  The eligibility criteria for a PhD in the USA can vary depending on the specific university and program. 

Can I get a PhD without a masters degree?

Yes, you can pursue a PhD without having a masters. Universities in the USA do not require a masters for you to apply. 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.

The eligibility criteria and requirements for direct entry PhD programs vary among institutions and fields of study, so it is advisable to check the entry requirements of the specific university or course you are interested in.

How to apply for a PhD in the USA

When applying for your chosen subject in the USA, you should expect to provide relevant information and statements to the university. This will include:

Completed application form – provided by your preferred university.

A personal statement – on why you want to study the subject, your research interests and career goals. Be sure to include any extracurricular activities and achievements within the body of your statement.

References – universities will expect that your referees will recommend you for the chosen course.

Test scores and grades – you will generally need to submit scores from standardised tests like the Graduate Record Examination (GRE) or the Graduate Management Admission Test (GMAT). 

English Language Proficiency – international applicants whose native language is not English usually need to provide proof of English language proficiency through tests like the Test of English as a Foreign Language (TOEFL) or the International English Language Testing System (IELTS). It varies from institution to institution, but international students in the USA are required to have a TOEFL score of about 90.

Samples of work – it is recommended that you provide some work you have done that is relevant to your chosen subject. You may even be asked to complete a small task during the application process.

Method of study

Compared to the UK and Europe , studying a PhD in the USA involves several key differences. Students in the USA are usually in direct contact with their professor, compared with those in the UK where students might find that their PhD program is headed by a professor who gives them a little less flexibility to change their research and study areas. There can be several cultural differences between UK, Europe, and USA university lifestyles. US students are expected to undertake a great deal of teaching and marking, as opposed to PhD students in Europe. 

As a result, you may have less free time outside of the university when pursuing a PhD in the USA.

Application for PhD In USA

When applying for your chosen subject, you should expect to provide relevant information and statements to the university. This might include:

A personal statement on why you want to study the subject. Be sure to include any extra-curricular activities and achievements within the body of your statement.

References. Universities will expect that your referees will recommend you for the chosen course.

Test scores and grades. It is important that you provide a list of your awarded grades from previous courses you have studied.

Samples of work. It is recommended that you provide some work you have done that is relevant to your chosen subject. You may even be asked to complete a small task during the application process.

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.

Application requirements for all doctoral programs (phd).

All of our doctoral programs are designed to develop outstanding educational researchers who have a deep understanding of the scientific, practical and policy issues they study. All require full-time study, and we promise five years of full-time financial support for every student we admit. Our doctoral programs are small, typically ranging from about 25 to 35 new students a year. The small size of our doctoral cohorts creates big educational advantages for students: the classes are almost always small, students receive individualized attention from their advisors, and they have many opportunities to develop close collegial relationships with fellow students.

It is extremely important to demonstrate in your statement of purpose that your interests converge closely with the current research of faculty who work in the program to which you are applying. Other doctoral applicants will certainly do this, and if you don't, you will forfeit an important competitive advantage to them. 

If you wish to contact faculty, please read our Which Degree Which Program article, by Professor Eamonn Callan, which outlines the appropriate process for contacting faculty with whom you share research interests. 

• Program website:  Degrees and Programs/PhD
• Length of Program:  5 years (average length)
• Tuition: fellowship/assistantship salary and tuition guaranteed for first five years of the program (autumn, winter and spring quarters) for all students, including international students. Funding includes two summers.

Application Requirements:

Application form.

Complete and submit Stanford's graduate online application .

Application Fee

The application fee is $125 , is non-refundable, and must be received by the application deadline.

Application Fee Waivers

Stanford offers three types of application fee waivers for which GSE applicants may apply and be considered:

• GRE Fee Reduction Certificate-Based Waiver
• Diversity Program Participation-Based Waiver
• School-Based Waiver

Please visit the Stanford Graduate Diversity website for instructions, deadlines, and the fee waiver application form.

Statement of Purpose

A Statement of Purpose is required. Your statement should be typed, single-spaced and should be between one to two pages . Describe succinctly your reasons for applying to the proposed program, your preparation for this field of study, and why our program is a good fit for you, your future career plans, and other aspects of your background as well as interests which may aid the admissions committee in evaluating your aptitude and motivation for graduate study. You may indicate potential faculty mentors as part of your study and research interests. Be sure to keep a copy for your records. What's a Good Statement of Purpose?

A resume or CV  is required of all applicants, depending on which document is most appropriate for your background. There is no page limit for resumes or CVs, though we typically see resumes of one page in length. Please upload your resume or CV in the online application.

Three (3) Letters of Recommendation

Applicants are required to submit three letters of recommendation . In the online application, you will be asked to identify your recommenders and their email addresses. Please notify your recommenders that they will receive an email prompt to submit their recommendation online. You can submit your request for letters of recommendation through the system without submitting the entire online application.  Stanford GSE only accepts online recommendations through the application system ; Stanford GSE cannot accept mailed, emailed or faxed recommendations.

Recommendations should be written by people who have supervised you in an academic, employment, or community service setting. We very strongly recommend that at least one of these letters be from a university professor familiar with your academic work. Your recommendations should directly address your suitability for admission to a graduate program at Stanford GSE.

It is the applicant's responsibility to ensure that all three letters of recommendation are submitted through the system by the application deadline , so please work closely with your recommenders to remind them of the deadline.

College and University Transcripts

Transcripts are required from every college and university you have attended for at least one academic year as a full-time student. When submitting your online application, transcripts should be uploaded to the application as a scanned copy or PDF ; this is sufficient for the application review process. Please refrain from sending a secured PDF/transcript with a digital signature as our system cannot upload these properly. The best way to ensure we receive an upload-able document is for you to print out the secured transcript, scan it, and upload the scanned copy (not to exceed 10MB) as a PDF. 

If you earned a degree at the institution from which you are submitting a transcript, please ensure that the degree conferral date and the degree conferred is clearly visible on the document. If you are currently enrolled in a degree program and will not have earned the respective degree by the time of submitting your GSE application, you should submit your most recent in-progress transcript from your institution.

Only if admitted will we contact you with instructions on sending two copies of your official transcripts to our office. We cannot accept mailed, emailed or faxed copies of your transcripts during the application process. Please note: the instructions for sending transcripts on the online application and on the general Stanford Graduate Admissions Office website differ from this Stanford GSE requirement.

Concerning course work completed in a study abroad program

If the coursework and grades are reflected on the transcript of your home institution, you do not need to submit original transcripts from the study abroad institution.

Concerning foreign institutions

If your institution provides a transcript in a language other than English, we require that you submit a translation of the transcript that is either provided by the institution or a certified translator. Translations must be literal and complete versions of the original records.

If your transcript does not include your degree conferral date and the degree conferred , please submit a scanned copy of your diploma, a conferral statement, or a conferral document in addition to your transcript . If you are currently enrolled in a degree program and will not have earned the respective degree by the time of submitting your GSE application, you should submit your most recent in-progress transcript from your institution.

Stanford University requires the Test of English as a Foreign Language (TOEFL) from all applicants whose native language is not English. The GSE requires a minimum TOEFL score of 250 for the computer-based test, 600 for the paper-based test or 100 for the internet-based test in order to be considered for admission. The Test of Written English (TWE) portion of the TOEFL is not required. Applicants who have completed a four-year bachelor's degree or a two-year master's program (or its equivalent) in the U.S. or at an institution where English is the main language of instruction are not required to take the TOEFL. For more information on TOEFL requirements, please refer to the Required Exams  page on the main Stanford Graduate Admissions website. You may register for the TOEFL test directly at the ETS website .

TOEFL Dates and Deadlines

PhD applicants who are required to take the TOEFL should plan to take the internet-based TOEFL test and have official TOEFL scores sent electronically to Stanford at institution code 4704 (department code does not matter) no later than November 1 . This will give your official TOEFL scores time to be sent from ETS and be received by our system in time for the December 1 deadline. PhD applicants to Knight-Hennessy Scholars should plan to take the internet-based TOEFL test no later than October 16 so your scores can be received by our system in time for the November 16 KHS GSE deadline. Please note that the TOEFL may be taken no earlier than 18 months prior to the application deadline.

Does Stanford accept tests other than TOEFL?

No. We accept only TOEFL scores; we do not accept IELTS or other test scores.
