We do not have a minimum GRE score requirement, and we do not track average scores for admitted applicants.
TOEFL - Applicants whose first language is not English must submit TOEFL scores from a test taken within the last eighteen months. The TOEFL is waived for individuals who have earned a U.S. bachelor's or master's degree from a college or university accredited by a regional accrediting association in the United States or the equivalent of either degree from a non-U.S. college or university of recognized standing where all instructions is provided in English. This exception does not apply if the courses were completed in a country where English is spoken but not all instruction is provided in English. Scores must be reported directly to Stanford from ETS. Your minimum score must be 100 (internet based) OR 600 (paper based). Please see the Graduate Admissions Office website for additional information about required exams. Stanford does not accept IELTS scores.
* Students are strongly advised to take the GRE and TOEFL no later than mid-October to ensure scores are transmitted by application deadline.
Letters of Recommendation
Following the instructions in the electronic application system, request that your three letters of recommendation be submitted electronically by the deadline. It is required by the University that at least one of the recommenders 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. Substitutions for faculty recommendations may include work associates or others who can comment on your potential for graduate work. All letters of recommendation must be received by the application deadline. Applicants are responsible for notifying references of the deadline.
What transcripts are required and how many?
A scanned version of the official transcript from every postsecondary institution you have attended for at least one year as a full-time student is required. Also request that ONE official transcript from all colleges and universities listed on the application, or in which you have attended full time for at least one year be emailed/mailed directly to Earth System Science (ESS) at the address below, to be received by the application deadline. While the University states that two transcripts are required, ESS needs only one for review purposes. The second transcript will be requested from admitted students prior to matriculation.
What is an ‘official’ transcript?
The PDF version of the transcripts you upload on line are considered "unofficial." The university requires "official" transcripts that are produced and sent directly by your university in a sealed envelope. eTranscript Service within the graduate application is available to current Stanford students and alumni who have active SUNet IDs.
Emailing/Mailing official transcription?
The University reserves the right to require additional academic documents, if we are unable to verify the nature or authenticity of your academic documents, we may ask you to obtain an evaluation from a foreign credential evaluation service.
Arrange for your official transcripts to be sent by the institution(s) to our department. An official transcript must be an original document bearing the institutional seal and official signature of the Registrar or copies verified by a school administrative officer and is one that is sent to Stanford in one of four ways:
Electronic delivery: The use of secure electronically-delivered transcripts that are pass code protected is necessary. 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.
CollegeNET Document Service: Applicants from international institutions are encouraged to use the CollegeNET Document Service within the graduate application to request and submit authenticated transcript(s) and other academic documents. This service provides official certified documents to the department to which you are applying.
eTranscript Service: Stanford students and alumni who have active SUNet IDs can use the eTranscript Service within the graduate application. See instructions in the application.
Postal service: You may send official transcripts yourself as long as the envelope has not been opened, as indicated by an unbroken seal with a signature or stamp across it. Find our program's mailing address below. Note: If sending paper transcripts, two sets are required; an official transcript is one that has been signed and sealed by the college/university registrar and is received by Stanford in its original, sealed envelope.
Transcripts must bear the official seal of the institution and signature of the Registrar.
- Academic records should give detailed information on the content and quality of your performance, courses taken each year, and grades received.
- The grading scale of the institution and your rank in class should be noted whenever possible.

Generally all Ph.D. candidates within ESS are provided full financial support for the first four years and for the duration of their doctoral work. There is limited funding for MS students.
Prospective students are strongly encouraged to apply for external fellowships, such as the National Science Foundation or equivalent funding opportunities. If the external fellowship is not sufficient to cover the standard department support level, a supplement will be provided by the University, the department or a research advisor. These fellowships strongly enhance your resume for your future career.
