Admissions Requirements

The GRE General Test is required. Other than that, there are no department-specific prerequisites for admission. Applicants for whom English is a secondary language are required to take the Test of English as a Foreign Language (TOEFL) and earn a score of 575 or higher (paper-based) or 233 or higher (computer-based) in order to be considered for admission.

The Department Process

After reviewing applicant files, the faculty invites those students who seem most promising to spend a full day at Penn. Prospective students who are invited to visit meet with faculty and graduate students and learnmore about our facilities, setting and program. Any interested student is of course welcome to attend one of our Monday workshops.
