How to apply for a PhD depends on the route before it depends on the university: in the UK you either apply for an advertised, often funded, project or propose your own, while most US programmes ask for a statement of purpose rather than a proposal. EdCitation publishes this guide, and every requirement in it comes from a university's or funder's own page, read on 27 September 2026 for 2027 entry. Places and studentships are competitive, and no guide can promise either.
Begin with the programme's own rules. Check your paper, free on EdCitation, turns application instructions into a list of word limits, headings, sources and style, and quotes the sentence behind every rule. EdCitation writes no part of an application or a proposal, and that is the point: several universities below forbid AI-written applications, and every sentence you submit must be yours. The proposal itself is covered in how to write a research proposal; this guide is about the application around it.
What does a PhD application ask for?
Most PhD applications want a proposal or a statement of purpose, a personal statement, a CV, transcripts and referees, plus a writing sample in some subjects. The table gives each page's requirements and limits as it states them.
| University | What the application asks | Limits | Source |
|---|---|---|---|
| Edinburgh (UK) | Research proposal for most research degrees; personal statement; references as the programme sets | Statement at most 3,500 characters, about 500 words; none, one or two references | University of Edinburgh (n.d.-b, n.d.-c, n.d.-d) |
| Bristol, School for Policy Studies (UK) | Personal statement; research proposal; two references, one academic; transcripts; at least one preferred supervisor named | Statement up to 500 words; proposal up to 1,200 words, reference list not counted | University of Bristol (n.d.) |
| Birmingham (UK) | Proposal if proposing your own research; personal statement; one or two references; example work if the tutor asks | Statement about 5,000 characters | University of Birmingham (n.d.-a, n.d.-b) |
| Imperial, Computing (UK) | CV; personal statement; research statement; transcripts; at least two reference letters; three or four named supervisors | Statement 1 to 2 pages; research statement 3 to 4 pages | Imperial College London (n.d.-c) |
| Harvard Griffin GSAS (US) | Statement of purpose; personal statement for some programmes; three letters; writing sample for some programmes | Statement of purpose at most 1,000 words unless noted; personal statement 500; Anthropology's writing sample at most 20 double-spaced pages | Harvard (n.d.-a, n.d.-b, n.d.-d) |
| Stanford (US) | Statement of purpose; optional 500-word statement; three recommendations; optional CV; programme questions | Statement of purpose: 1,000 words is the "maximum recommended length" | Stanford (n.d.-b, n.d.-c) |
| Sydney (Australia) | A supervisor's written agreement first; research proposal; two referee reports on the university's forms | Proposal up to 2,000 words | University of Sydney (n.d.) |
| The programme you choose | Its own page and form | As its own page sets them | Paste them into EdCitation's Check your paper, free, and get each limit listed |
What the table does not settle
Edinburgh and Birmingham leave the proposal's length to the programme, and Imperial says a proposal is not always required. Deadlines vary too: Harvard's PhD in Anthropology closes at 5:00 pm on 1 December 2026, and Stanford's Electrical Engineering PhD at 11:59 pm PST the same day. Oxford's, UCL's and Melbourne's pages would not open for us, so they are left out.
Funded project or your own proposal?
An advertised project comes with a topic, a supervisor and often the money, and you apply to it; a self-proposed PhD starts with your idea, and you find the supervisor and the funding. Birmingham runs the two as separate routes: for an advertised PhD you read the project's funding, entry requirements and deadline, and for your own research you find a supervisor and write a proposal first (University of Birmingham, n.d.-a, n.d.-b). Imperial adds that on a funded project your supervisor is usually the academic who won the funding (Imperial College London, n.d.-a).
How UKRI studentships and doctoral training partnerships work
UK Research and Innovation pays for its studentships through universities and other providers, and students cannot apply to UKRI directly; they apply to the university or other provider offering the studentship (UK Research and Innovation, 2026b). From 1 October 2026 the minimum stipend is £21,805 a year, or £23,805 with London weighting, which the EPSRC does not offer. UKRI pays fees only up to the home rate, £5,238 at minimum for 2026 to 2027, so an international student may have to contribute.
UKRI now funds doctoral training through two kinds of award: landscape awards, broad and spread across subjects, and focal awards, aimed at strategic areas. Existing doctoral training partnerships sit with the landscape awards and centres for doctoral training with the focal ones (UK Research and Innovation, 2026a). So a "DTP" and a "DLA" may be the same scheme under an old and a new name.
Two partnerships, two routes
Cambridge's NERC partnership, CREATES, offers fifteen 3.5-year studentships for October 2027. It lists topics and supervisors but no finished project titles: you name your preferred topics in order, write a 250-word summary of your research interests, and shape the project with your supervisors in the first term. Deadlines are 8 December 2026 or 6 January 2027, depending on the department, with references due by the same date (University of Cambridge, n.d.-b).
The White Rose Social Sciences DTP, as York describes it, funds candidates who propose their own project through Pathway Awards. You apply for a place first, by your department's earlier internal deadline, and the department selects who goes forward; the final form is due by 20 January 2027, and a department's choice is a nomination, not an offer. The ESRC limits awards to international applicants to 30%, and winners are expected by 23 April 2027 (University of York, n.d.).
Edinburgh's proposal guide warns that funding does not always guarantee a place, and that funders reject applications breaking format rules, such as font size or page count, before review. Start about a year ahead, it says (University of Edinburgh, 2025).
How to email a potential PhD supervisor
Email a potential supervisor when the programme expects it, and check first whether it does: universities differ most here.
- Sydney: outside Law and Business, you must secure a supervisor before applying. The email covers your background, research experience, topic and how it fits their work, with your resume, transcripts and an initial proposal attached (University of Sydney, n.d.).
- Bristol, School for Policy Studies: contact staff to discuss your proposal before you write the application; the School says applicants who have done so have a greater chance of an offer (University of Bristol, n.d.).
- Imperial: a formal email that shows you know their expertise and past work. Once the project is discussed, ask how many students they supervise and how often you would meet (Imperial College London, n.d.-a).
- Edinburgh: check the staff profile says they take supervision enquiries; some are already at their limit, and you may need a proposal ready (University of Edinburgh, n.d.-a).
- Toronto: in most units finding a supervisor is the student's job, and securing one may be a condition of admission (University of Toronto, n.d.).
- Stanford Electrical Engineering: contacting faculty is not required and does not guarantee admission, because the admissions committee decides (Stanford University, n.d.-a).
Stanford's School of Humanities and Sciences (n.d.) says that in some fields you are admitted to one professor's group, so there you should write; if there is no reply, wait a week and try once more.
Our template for a first email
This outline is ours, built from the advice above; the words are yours. Subject line: your intended topic and start year. Paragraph one: who you are and your degree. Paragraph two: the paper of theirs you read and the question it left you with. Paragraph three: your idea in three or four sentences. Close with one specific question, such as whether they are taking students for 2027. Attach your CV, and your proposal where the programme asks for it.
How to write a PhD statement of purpose
A US statement of purpose sets out your research interests, preparation and reasons for choosing the programme; both schools we read put the limit at 1,000 words. Harvard's graduate school asks for your reasons for doctoral study, the experiences that shaped your research ambitions, a brief word on career aims and your past work, and a separate 500-word personal statement that complements rather than repeats it (Harvard Kenneth C. Griffin Graduate School of Arts and Sciences, n.d.-d). Its Anthropology page is blunter: a statement of purpose "is not a biographical narrative", and applicants should read the publications of the faculty they hope to work with (Harvard, n.d.-a).
Stanford's prompt asks for your reasons for applying to the programme, your preparation, research interests and career plans, and warns that a programme's own prompt may differ (Stanford, n.d.-c). For how a personal statement differs, and what Berkeley and Cornell ask, see how to write a personal statement.
Letters of recommendation
Harvard wants three letters through its portal, at least one from a faculty member where you took your most recent degree unless you left more than five years ago, and asks whether you waive your right to see them (Harvard, n.d.-c). Stanford says recommenders must write their own letters: drafting one yourself, even when asked, breaks its terms (Stanford, n.d.-b). Edinburgh is the other way round: references there cannot be confidential, and referees should share them with you (University of Edinburgh, n.d.-c).
What the AI rules say
Harvard allows AI only for minor edits and grammar and forbids it for developing the work (Harvard, n.d.-b). Imperial's Computing department expects every statement to be written without generative AI, and Bristol's School for Policy Studies treats a proposal developed with generative AI as plagiarism. The scholarship programmes' rules are in how to write a scholarship application.
What happens at a PhD interview?
A PhD interview, as the pages below describe it, is a short talk on your interests or past work, then questions on the field and on your fitness for research. Imperial interviews every applicant before an offer, with at least one and normally two staff plus the Director of Postgraduate Studies or the head of department, by video if you cannot visit (Imperial College London, n.d.-b). Its Computing department adds that you may present a past project or discuss papers your potential supervisor asks you to read.
Cambridge's CREATES panels are three or four academics on Zoom for 25 to 30 minutes. You give a five-minute presentation, then answer core questions asked of everyone and some of your own: the open questions in the field, the skills you bring, and what makes a good doctoral researcher. Your questions at the end are not assessed (University of Cambridge, n.d.-a). Interviews are expected in the week of 22 February 2027.
Stanford's Humanities and Sciences advice: read your interviewers' papers, prepare a question or two for each, summarise your own research in one to two minutes, and rehearse in a mock interview. See also how to prepare for a graduate interview.
A checklist for your PhD application
The checklist is ours. It orders the work; the writing is yours.
- Choose the route: an advertised project, your own proposal, or a US-style statement of purpose.
- Gather every set of instructions: programme page, central admissions pages, funder. Run each through EdCitation's Check your paper and keep the limits it lists.
- Note every deadline, including department and funding deadlines that come before the main one.
- Contact supervisors as the programme advises, well before its deadline.
- Find the reading for your proposal in Find sources, which searches about 300 million published works, free.
- Draft the proposal to the length set (see how to write a research proposal), then the statements, without repeating one in another.
- Build and check the references with Cite a source and Verify references.
- Brief your referees early with your CV and proposal.
- Read each programme's AI rule, then submit before the deadline, not on it.
How EdCitation helps with a PhD application
EdCitation reads the rules and checks the references, and leaves every word of the application to you. For the rules, Check your paper is, in our view, the best first step: it is free with no account, it quotes the sentence behind each rule, and it lists what it set aside, so you see exactly what it read and what it left to you.
Check your paper on application instructions of our own
We wrote eleven lines of application instructions for an imaginary PhD, marked as ours and no university's, and pasted them in. Nine rules came back: Font, "Times New Roman"; Font size, 12 pt; Line spacing, 1.5 ×; Margins, 0.98 in (from "2.5 cm margins"); Word count, 1,500 to 2,000 words; Sources, at least 15; Source dates, "Most of the sources: from the last 10 years"; Citation style, "Harvard"; Required headings, Background, Research Questions, Methodology, Timeline and References.
It set aside six lines:
- "Your personal statement must be no more than 3,500 characters."
- "Your CV must be no longer than two pages."
- "Submit a writing sample of up to 20 double-spaced pages."
- "Name one or two potential supervisors and confirm you have contacted them."
- "Provide two academic references by the closing date, 15 January 2027."
- "Do not use generative AI tools to write any part of your application."
The nine rules are the ones a proposal can be checked against; the six set-aside lines are the tasks and documents around it, for your own list.
References, and a check of the whole draft
A proposal's references can be checked against the record, so check them before a reader does. Cite a source builds each from the publisher's record, and Verify references, free, looks every entry up and returns it verified, "check this" or not found, flagging retracted papers and never showing "could not check" as not found. Theoretics QA, part of Max at $24 a month (see pricing), judges a draft against its own instructions, quoting it and rewriting nothing. It promises no place.
Quick questions
How long should a PhD research proposal be?
As long as the programme says. Among the pages we read, Bristol's School for Policy Studies allows up to 1,200 words, Sydney up to 2,000, and Imperial's Computing department 3 to 4 pages.
Can I apply to UKRI for PhD funding?
No. UKRI funds studentships through universities and other providers, and students apply to the provider offering the studentship.
Do I need to contact a supervisor before applying for a PhD?
It depends on the university. Sydney requires a supervisor's agreement before you apply, Bristol's School for Policy Studies expects contact first, and Stanford's Electrical Engineering department says contact is not required.
How long is a PhD statement of purpose?
Harvard's graduate school sets at most 1,000 words unless a programme says otherwise, and Stanford gives 1,000 words as the maximum recommended length.
Can EdCitation check my PhD application's requirements?
Yes. EdCitation's free Check your paper lists the limits, headings, sources and style an application's instructions set, quoting the sentence each came from. It never writes or edits any part of the application.
