PhD Admissions Frequently Asked Questions
Prospective Applicants (PhD)
While there are no specific prerequisite courses to complete before applying, previous experience has shown that before starting the core courses students need to have mastered the material in courses such as Stanford's Math113, Math115, Stats116, Stats200, and CS106A (or their equivalents at other universities), as demonstrated by very strong and relatively recent grades. Descriptions of these courses may be viewed on Stanford's ExploreCourses course listings pages. Note that up to and including academic year 2015-16, the Stats305ABC sequence is called Stats305, Stats306A and Stats306B respectively. Where this background is missing or not recent, admission to the Ph.D. program will involve working with the Graduate Director to design an individual program to make up the necessary courses.
The Bechtel International Center works with students, staff and faculty and their families on issues including immigration policy, academic and financial difficulties, transactions with foreign governments, English proficiency, housing, and adjustment to life at Stanford. Contact the center at 584 Capistrano Way, Stanford, CA 94305-8245, (650) 723-1831, or visit the Bechtel web site.
No, we only matriculate students in autumn quarter and therefore all applicants must meet the annual Ph.D. application deadline.
No. It is not possible to complete a degree online in the Statistics Department. The department offers a small number of courses online through SCPD, mostly in summer, but the majority of courses must be completed on campus during normal business hours.
Please visit Estimated Expense Budget for information about the estimated cost of living on-campus as a graduate student (this is only an estimate; your actual expenses may differ).
Please visit Student Housing for information about campus housing at Stanford, including information on eligibility, application process, and deadlines.
Students with a strong mathematical background who wish to go on to a PhD in Statistics should consider applying directly to the PhD program. Completing the MS in Statistics does not help one's chances of admission to the PhD program.
No, you may apply to only one degree program per academic year. An exception is within the Biosciences, in which you may apply to up to three PhD programs within your one application. However, you may apply concurrently to one departmental program and to a professional school program (law, medicine or business).
We receive approximately 120 PhD applications each year, and usually admit 10-12 new students each year.
Graduate Exam Requirements (PhD)
Applicants applying to the doctoral program in Statistics must take the Math subject exam.
Note: Unlike the general test, the math subject test is only offered three times each year. Check here for dates. Applicants interested in biostatistics are also required to take the math subject test.
The General GRE is required of all applicants applying to a graduate program in statistics at Stanford University, including applicants who have previously attended graduate school.
The Statistics M.S. degree application only requires the General GRE. Please arrange to take the exam early to ensure that your scores reach us by the application deadline. If you will not have your unofficial scores by the deadline, then it will be too late for you to apply. We cannot update an applicant's scores after the application deadline.
We do not have minimums required for application, but do expect students to have earned high a GPA and GRE scores.
Applicants who have already earned a Ph.D. degree, or have Ph.D. studies in progress with a degree conferral date prior to the intended start quarter, may request a GRE General Test waiver by emailing stat-admissions-PhD@lists.stanford.edu with the following information: full name, institution attended, degree earned, and degree conferral date. Use the subject heading 'GRE General Test Waiver Request'.
The average scores of admitted Statistics PhD applicants:
- General GRE scores (percentiles):
- Quantitative 95%
- Verbal 90%
- Analytical Writing 74%
- Math Subject GRE score (percentile): 90%
No, we do not accept any tests in lieu of the GRE general and math subject tests.
Please make sure to have your electronic scores sent to Stanford prior to their expiration date.
GRE scores are valid for approximately five years from the exam date.
TOEFL scores submitted to Stanford must be from a test taken within the last 18 months. (If your scores are still valid, but are close to the 18 month cut-off, please submit them to Stanford ASAP.)
ETS will not send scores that have expired.
Applicants should have the Educational Testing Service (ETS) send scores electronically to Stanford. Our university code is 4704. It does not matter what department code is specified. You will either self-report your scores or indicate the date you will take the test(s) in the online application. Self-reported scores will not be considered official until Stanford receives the electronic record.
Please verify that you do not have to take the TOEFL by visiting the Graduate Admissions Required Exams webpage:
Once you have received confirmation from the Graduate Admissions Office that your TOEFL waiver request has been approved, you must forward this notification to email@example.com
Applications checklists can only be updated with the TOEFL exemption when the application has been submitted and official transcripts have been reconciled with application.
Note: To bypass the entry of TOEFL scores in the application, enter a future exam date. You can add in the Additional Information section of the application that you have received a waiver from Graduate Admissions. https://gradadmissions.stanford.edu/about/frequently-asked-questions/gre-and-toefl
The University does not accept IELTS scores in lieu of the TOEFL. https://gradadmissions.stanford.edu/about/frequently-asked-questions/gre-and-toefl
(The University does not accept IELTS scores.)
Recommendation Letters (PhD)
Your recommenders are required to submit their letters through the online application by the deadline of the round in which you apply. You are responsible for ensuring the letters are submitted on time. You will be able to see the status of each letter (either notified, started, or submitted) and you will also be able to send a reminder via the online system to any recommender who has not yet submitted as the application deadline draws near.
- Register your recommenders. Go to the “Letters of Reference” tab on the application, and enter each recommender’s information carefully. It is essential that you enter the recommender’s email address correctly so that your recommender can access the instructions and form. Read the waiver statement for each letter of reference and determine whether or not you will waive your right to review each recommendation. You cannot change this later.
- Your recommender receives an email with log in information.
- Your recommender completes and submits his/her recommendation.
- You and your recommender receive an email confirming the recommendation has been submitted.
Waiving your FERPA Access Rights
Once you are an enrolled student, the Family Educational Rights and Privacy Act of 1974 (FERPA) provides you with a right of access to your education record, including letters of reference if they are retained by the school. The law also permits you to waive that right of access to your letters of reference if you so choose. Waiving your right of access to your letters of reference is optional; your decision to waive or retain that right will have no bearing on the handling of your application.
The recommenders whom you notify will be able to see whether or not you have waived your FERPA right of access during the letter of reference submission process. You must waive or retain your rights of access to your letters of reference (using the online application system) before you invite recommenders to submit information for you.
Letters must be submitted using the electronic application. As part of the online application, the applicant will be required to register the names and contact information, including e-mail addresses, of each recommender. Recommenders will then receive an email with directions on how to proceed. For additional information, please visit the Letters of Recommendation page provided by the Office of Graduate Admissions. Letters must be received by the published deadline. It is the applicant's responsibility to ensure that letters are submitted to the electronic application by the published deadline. Do not email, mail, or fax letters of recommendation that have already been submitted through the online application.
Yes. If this applies to you, you will still need to enter information for each recommender in the online application, including e-mail addresses which will automatically generate the email to each recommender requesting a letter. It is your responsibility to contact them to let them know to disregard this email and to use the university's letter service.
The department only requires three letters of recommendation. It is the quality, not the quantity, of letters that supports the graduate application. At least one recommender should be a faculty member at the last school you attended as a full-time student (unless you have been out of school for more than five years). Your application will still be reviewed if you submit more than three letters of recommendation. Note: If you have any concerns that one of your recommenders will not be able to submit their letter by the deadline, you may want to consider requesting letters from a total of four recommenders. This will increase the likelihood that three letters will be submitted by the deadline and that your application will be considered complete.
You should choose individuals who:
- Know you well through significant, direct involvement with you within the last three years
- Will provide detailed anecdotes and examples to support their assertions
- Are truly enthused to write a recommendation for you and will spend sufficient time writing a thoughtful letter
All applicants are required to send official transcripts to the degree program in which they are applying by the application deadline. Transcripts are documents establishing an applicant's academic record from their previous institution for one year or more (full-time enrollment).
What not to submit:
- Hard copies of your transcripts from continuing studies programs; extension schools; online courses; all other transcripts that reflect less than 1 year of a full-time degree program. [These can be included under the Additional Information: Document Uploadssection on page 15 of the application.]
Receipt of official transcripts will be recorded in the applicant checklist (Activity Status page and viewing your checklist). Transcripts cannot be reconciled with the student's application until the it has been submitted. We recommend sending your transcripts to the department within 7 days of submitting your application.
Please note, the purpose of the checklist is to allow applicants to monitor the status of their application materials. Please allow up to 3 weeks for official transcripts to be recorded as "RECEIVED" on the application status page.
Arrange for either one (1) physical official transcript or one (1) official electronically submitted transcript to be sent by the issuing institution(s) to the department by the application deadline. An official transcript must be an original document bearing the institutional seal and official signature of the Registrar or is verified by a school administrative officer.
Electronic transcripts are strongly preferred to facilitate and expedite processing of applications and should be sent to stat-admissions-PhD@lists.stanford.edu.
E-transcripts are secure electronically-delivered transcripts that are pass code protected. The document's certified digital signature embedded in the document PDF assures us that it has been prepared by the college/university and that the document is original and unaltered. Please check with the registrar's office of your college/university to see if they provide secure electronic certified transcript service. Transcripts sent as email attachments are not accepted.
Please mail your official (paper) transcripts to:
Statistics Ph.D. Graduate Admissions
Statistics Department, Sequoia Hall
390 Jane Stanford Way, Room 222
Stanford, CA 94305-4020
Official transcripts from Chinese university's will now be processed via CHESICC and routed through the graduate admissions application system. This service is optional, however, it is preferable to receiving hard copy transcripts by mail.
If you choose to use this service, you will still need to upload your transcripts in the application and then proceed with the request to process your transcripts within the application. When your CHESICC electronic documents are processed and received by Stanford, applicants will not need to send official paper transcripts to the department.
If the institution does not issue records in English, original language records must be submitted with official English translations. We accept translations issued by the institution or a professional translating service. Translations must be literal and complete versions of the original records. Transcripts submitted through a credentials evaluation service will also need to be accompanied by the original documents. https://gradadmissions.stanford.edu/applying/international-applicants/transcripts-academic-records.
International students do not need to submit transcripts via an evaluation service unless your institution does not offer these documents in English.
Application Submission (PhD)
No. We do not allow deferral of admission. Students who are accepted but cannot enroll may reapply for a future year when they are available to begin their studies.
Yes, you must submit a complete application, pay the application fee and submit new letters of recommendation and official copies of transcripts.
Applicants who indicate that they would like to be considered for the Master's program in the 'Application Options' section of the online application are eligible to request that their application be reviewed by the MS Admissions Committee. In order to pursue this option, the applicant must directly respond to the PhD admissions decision email within three business days indicating this request. However, we cannot guarantee that the Graduate Admissions Committee will accept your application request for the master's program. You will be notified via email whether your request has been granted.
