Admissions & Application Details


The graduate program in Mathematics leads only to the Ph.D. degree. Students are not accepted for an M.S. degree.

Applicants must demonstrate mastery of the material required for an undergraduate major in mathematics.

We welcome applications from and admit students with various mathematics backgrounds.

Application Guidelines

Complete an application online and upload the following by December 15, 2022:

  • A statement of purpose in which you describe your experiences and goals in mathematics. This essay is a great way to draw the attention of the admissions committee to your accomplishments.

  • Three letters of recommendation. Additional letters are allowed. 

  • Transcripts (either official or unofficial) from the institution at which you are currently enrolled and/or from any institution from which you have received or will receive a degree. All transcripts must be combined into one PDF document and uploaded. If it is against an institution’s policy to send official transcripts to you, please request an unofficial copy for yourself and scan that document. Paper copies will be accepted only if the first two options are not available to you. If you are subsequently admitted and accept the offer of admission, we will require a formal and official paper transcript prior to matriculation.

GRE scores will not be considered.

Cornell University expects all applicants to complete their application materials without the use of paid agents, credentials services, or other paid professional assistance. The use of such services violates University policy, and may lead to the rejection of application materials, the revocation of an admissions offer, cancellation of admission, or involuntary withdrawal from the University.

TOEFL Requirement

TOEFL (Test of English as a Foreign Language) scores are required for international students whose native language is not English. Only students who have studied full time for two or more years at a college or university located in a country where English is the native language and where English is the language of instruction are exempt from the TOEFL at the time of application. More information on language requirements.

The minimum TOEFL requirements are as follows: IBT test (replaced CBT) after September 1, 2009:

20 Writing
15 Listening
20 Reading
22 Speaking

All four scores must be reported. Applicants will not be considered if any minimum score is not met.


The Graduate School requires an overall band score of a 7.0 or higher on the IELTS (International English Language Testing System). Scores must be delivered electronically through the IELTS E-Delivery service to the Cornell University Graduate Admissions e-download account. E-delivery may also be referred to as an e-TRF by your test center.

Admission Decisions

The first round of admission decisions are made in mid-February. We typically continue to consider applications and make offers until April 15. Under the rules of the Council of Graduate Schools, students have until April 15 to make their decisions.

Financial Aid

Everyone who applies for admission to the graduate program in mathematics is automatically considered for financial aid. For many years the field has been able to provide financial support — through a teaching assistantship, fellowship, or graduate research assistantship — to every graduate student who is making satisfactory progress towards the Ph.D. degree, and it expects to continue this practice.

Some of our students have fellowships from the National Science Foundation or other sources. However, most are supported by Teaching Assistantships, which pay $28,654 for 15 hours per week in 2021–2022. Duties may be (i) grading for advanced courses, (ii) giving recitation sections, or (iii) teaching a section of calculus. Assignments to courses are made by the Director of Teaching Assistant Programs, Senior Lecturer Kelly Delp, but are based on the students' requests.

Summer Aid

We try our best to find summer support for any student who would like to remain in Ithaca during the summer. We also encourage students to apply for other forms of summer support that enhance their graduate education.

Equal Opportunity

It is the policy of Cornell University to actively support equality of educational and employment opportunity regardless of race, religion, national or ethnic origin, sex, age, or handicap.

Applied Mathematics

We accept applications from students interested in Applied Mathematics. Note that Cornell University has a separate Ph.D. program in Applied Mathematics and students can apply to both programs.
