The Subject Examinations are used by medical schools to measure their students' knowledge across a broad range of topics.

They include both the Basic and Clinical Science exams, which serve to assess students at the end of a course or clerkship, and the Comprehensive exams, which help to gauge readiness for the USMLE®.
