Who Takes Them?

Prospective graduate school applicants take the Subject Tests. Applicants come from varying educational and cultural backgrounds, and the GRE Subject Tests provide a common measure for comparing candidates' qualifications.

GRE Subject Test scores are used by admissions or fellowship panels to supplement your undergraduate records, recommendation letters and other qualifications for graduate-level study. Some Subject Tests yield subscores that can indicate the strengths and weaknesses in an individual test taker's preparation and may also be useful for guidance and placement purposes.

Who Accepts Them?

GRE Subject Test scores are accepted by thousands of graduate schools, including individual departments or divisions within these schools. See a list of Institutions and Fellowship Sponsors Approved to Receive GRE Scores.

Although the scores may not be a requirement for admission to a particular program, admissions committees are likely to consider the scores if they are submitted. It's best to contact the specific graduate program you're interested in and inquire about their requirements.
