  1. Unofficial transcripts of your grades

Application Information

All applications for graduate study are processed through the Graduate Admissions Office, which provides an online application. Our school code for 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 the 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. Applicants will be notified of a fee waiver decision within one week after the applications are submitted. Please email gs[at]princeton[dot]edu with any questions. Participants in the National Institutes of Health's Enhancing Neuroscience Diversity through Undergraduate Research Education Experiences (ENDURE) program may request fee waivers by emailing Ed Clayton at ec12[at]princeton[dot]edu.
