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.

Graduate School

Ph.d. requirements.

• Academics & Research
• Programs & Requirements

Brown University awards more than 200 doctor of philosophy degrees annually.

The Brown Ph.D. is primarily a research degree. Teaching is an important part of many doctoral programs, and many departments require candidates for the Ph.D. to have teaching experience.

Brown University offers substantial financial support to doctoral students. All incoming doctoral students are guaranteed five years of support, which includes a stipend, full tuition remission, health-services fee, and a health-insurance subsidy. Doctoral students in the Humanities and Social Sciences are guaranteed six years of support. All promises of student support are subject to students making satisfactory academic progress, as determined by their programs of study. Please see related links for additional details regarding the University's commitment to doctoral education.

Ph.D. Funding

Funding guarantee, four general requirements for the doctor of philosophy.

The candidate must be formally admitted to his or her degree program.

The normal residency requirement is the equivalent of three Academic Years of full-time study beyond the bachelor's degree. Students who enter a PhD program at Brown already holding a master’s degree in a related field have a residency requirement equivalent to two Academic Years of full-time study upon entering the PhD program at Brown. Use of a previously earned master’s degree to reduce PhD residency requirements is contingent upon approval of the program Director of Graduate Study. Graduate work done at other institutions and not used in fulfillment of the requirements for any doctoral degree elsewhere may, on the approval of the program Director of Graduate Study, be counted in fulfillment of up to, but not exceeding, one year of the residency requirement. A student who desires credit for work done elsewhere should file a timely application with the program Director of Graduate Study; transfer credit forms are available through the  Office of the Registrar .

A student is advanced to candidacy for the Ph.D. when he or she has completed satisfactorily all the requirements, departmental and general, requisite to beginning work on the dissertation. Candidacy is determined by the department or program of study and certified by the Registrar. Most departments require a preliminary examination before advancing any student to candidacy. Most departments also require a final examination or defense. The examination is conducted by professors in the department and by such other members of the faculty as may be appointed.

The candidate must present a dissertation on a topic related to his or her area of specialization that presents the results of original research and gives evidence of excellent scholarship. The dissertation must be approved by the professor or committee under whose direction it is written and by the Graduate Council. All requirements for the Ph.D. must be completed within five years after advancement to candidacy.

Faculty Member Leaves Brown

If a faculty member working with a doctoral student leaves Brown for any reason before that student has completed his or her degree requirements, it may not always be possible for that faculty member to continue working with the student as an advisor. In such cases, departments will work with students to help them locate a new advisor.

Additional Requirements

Individual departments and programs may have additional requirements regarding the number of courses to be taken, proficiency in foreign languages, special examinations, and theses. The department should be consulted for specific information.

• PhD in USA – A Guide for 2024/25
• 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 2024 , 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.

• PhD/Master's Application Process

Who is Eligible to Apply? 

If you have completed your undergraduate degree (bachelor's or equivalent) or will have completed it prior to your intended matriculation date at Yale, you may apply to the Graduate School of Arts and Sciences (GSAS).

A Master's degree is not required to apply for a PhD at Yale, although some programs give preference to applicants with post-baccalaureate training. Consult your program of interest directly for information on how it evaluates applications.

We value diversity of all kinds at the Graduate School, and we encourage students from all backgrounds to apply if Yale is a good fit for your intellectual and professional goals. All are welcome to apply, without regard to citizenship or immigration status, socioeconomic level, race, religion, gender identification, sexual orientation, disability, etc.

Requirements for All PhD and Master's Degree Applicants

You will need to provide the following with your application for admission:

• A statement of academic purpose. You will find the prompt for the statement of purpose in our Application Question FAQs . 
• A list of all the prior colleges or universities you have attended, accompanied by unofficial transcripts from each school. Unofficial transcripts should be uploaded with your application. Official or paper transcripts are not needed at this time. 
• Three letters of recommendation. Enter the names of your recommenders directly in the application and they will receive a link to upload a letter on your behalf. 
• $105 application fee or fee waiver. 
• Standardized tests . GRE requirements vary by program. TOEFL or IELTS are necessary for most non-native English speakers. 
• Resume/CV . 
• Some programs have additional requirements, such as a writing sample . You can find information about any specific requirements on the program's website. 

Where Do I Begin?

Decide whether you will apply for a PhD or a terminal Master’s (MA, MS) in one of the programs available at the Graduate School of Arts and Sciences . (Note that you will earn one or more Master's degrees en route to a PhD.) Learn about the program: its faculty, course offerings, and resources. Read the faculty's research publications. If you can identify and articulate why the program is a good fit for you and show how your preparation and interests align well with it, you will have a strong application.

A note to students applying to one of Yale’s professional schools or programs:

• If you are applying for a PhD in Architecture, Environment, Investigative Medicine, Law, Management, Music, Nursing, or Public Health; for an MS in Public Health; or for an MA in Music, be sure to use the Graduate School of Arts and Sciences PhD/Master's application.
• If you are applying for any other degree at one of the University’s professional schools (Art, Architecture, Divinity, Drama, Environment, Global Affairs, Law, Management, Medicine, Music, Nursing, and Public Health), visit that school’s website for further instructions. Those programs have separate admissions policies and processes that are administered by the professional schools, not GSAS.

Application deadlines vary by program, so please see Dates & Deadlines for information about your program of interest. 

All new students matriculate in the fall. The admissions process begins nearly a year in advance of matriculation.

Some PhD and Master’s degree programs require Graduate Record Examination (GRE) scores. Check your program's standardized testing requirement before you apply. 

In addition, applicants whose native language is not English may need to take an English Language test (TOEFL or IELTS).

The application for Fall 2025 entry is now available. 

Be sure to complete and submit the application before your program's application deadline. 

Your application fee or an approved fee waiver is due upon submission of your application. 

Your letters of recommendation do not need to be received before you will be able to submit your application. However, since programs begin reviewing applications shortly after the respective application deadline, please be sure that your letters of recommendation are submitted promptly.

What Happens After I Submit My Application?

The faculty admissions committee in each department and program begins reviewing applications shortly after their application deadline. Led by the director of graduate studies (DGS) or director of graduate admissions (DGA), the committee will recommend students for admission to the Graduate School. Once confirmed by the deans of the Graduate School, the admissions office will release final decisions to applicants.

Unlike undergraduate admissions, the admissions office and staff of the Graduate School maintain the application, the application process, and other administrative transactions, but the admissions staff does not review applications or make admissions decisions. That responsibility is handled by the faculty of each department or program.

Most admissions decisions are provided between February and early March. You will receive an email notification when your admissions decision is available.

If you are accepted for admission, you will need to decide if you wish to accept our offer by April 15. We abide by Council of Graduate School's April 15 Resolution , regarding graduate financial support.
