Applications will be accepted in September for the incoming Class of 2017. The Deadline to apply is November 28, 2016. The admissions deadline this year is earlier than usual. Please check the graduate school webpage for additional information.

We require a completed web based application including:

  1. Official transcripts of your grades
  2. Three letters of recommendation
  3. For students whose native language is not English and who have not received their undergraduate education in a U.S. college or university: official TOEFL exam scores from ETS

Applicants are required to take the GRE examination from ETS and to request that scores be sent directly to Princeton. This test can be taken all over the world. Almost all applicants submit scores for the GRE General Test. Many applicants also submit scores for one of the science Subject Tests.

Application Information

All applications for graduate study are processed through the University's Graduate Admissions Office, which provides an on-line application.

Our school code for GRE and TOEFL is 2672. No department code is required.

Requests for application fee waivers will be considered for U.S. citizens or permanent residents on the basis of significant financial hardship, or if you have participated or are currently participating in one of several eligible programs (see Fee Waivers). Proof of program participation will need to be uploaded along with your application. The fee waiver option is accessible through the payment section of the admission application. If you choose that option, the fee waiver application will become part of your admission application and must be submitted by the application deadline of November 28th. Applicants will be notified of a fee waiver decision within one week after the applications are submitted. Please email gs[at]princeton[dot]eduwith any questions.

Financial Support

All admitted students receive full financial support for the duration of their Ph.D., including tuition, a competitive stipend, and health benefits. This support is made possible through a combination of funds from Princeton University, federal grants to PNI, generous private donations, and grants to faculty members.

For complete details and deadlines see The Graduate School at Princeton University.
