NBME Subject Exams help medical schools measure their students’ knowledge across a broad range of topics.

Demonstrate Your Knowledge and View Performance Feedback

The Basic and Clinical Science Subject Exams are often used as a final assessment at the end of a course or clerkship, while the Comprehensive Exams are used to gauge readiness for the USMLE®.

Taking an NBME Subject Exam enables you to demonstrate your mastery of the knowledge and skills needed to become a successful physician and progress on your journey through medical school. Plus, with performance feedback reports that identify your relative strengths and weaknesses across content areas, you can learn where you need to improve and better target your studies going forward.
