Admission to the Ph.D. program is highly competitive. Previously successful applicants generally present a grade point average above a 3.5 on a 4.0 scale, a quantitative GRE score above 160 (760) and a verbal GRE score above 153 (500). International students from non-English speaking countries are required by the Graduate School to achieve minimum scores on each of the subsections of the TOEFL exam (see below).

Ph.D. applications are accepted for the Fall semester only. The deadline for Fall admission is December 15. This is the deadline for the applicant to submit the application—reasonable amount of time is allowed for letters of recommendation and official test scores to be received once the application has been submitted.
