You are now only one step away from getting licensed to practice medicine independently. The USMLE Step 3 is vital in your dream journey of becoming a doctor. But before you even start preparing for the exam, it is crucial to understand it. Hence, in this article, we will get an overview of the USMLE Step 3, its scoring, exam format, and content outline.

What Is The USMLE Step 3?

USMLE Step 3 assesses your knowledge and skills for providing independent care to patients in an ambulatory setting. The last step in the USMLE sequence will allow you to practice medicine without supervision.

Examination materials are prepared by examination committees that represent a wide range of medical specialties. Among the members of the committees are academic and non-academic expert practitioners, as well as state medical licensing board members.

Step 3 tests your ability to perform as a generalist medical practitioner in the United States. The test items and cases simulate the clinical situations you may encounter as a general yet undifferentiated physician in a specific setting.


To be eligible to take Step 3, you should have fulfilled the following requirements-

  • Gotten passing scores in Step 1 and Step 2 CK. AND
  • An MD or DO degree from a US or Canadian medical school accredited by the LCME or COCA or a medical degree from a college recognized by the World Directory of Medical Schools as satisfying the ECFMG eligibility requirements and obtaining ECFMG certification in the same level of the MD degree from a school outside of the US and Canada, AND

It is also recommended that you complete at least one year of post-graduate training in an authorized US graduate medical education program that complies with state board licensing requirements.

Exam Format:

The USMLE Step 3 consists of Multiple-Choice Questions (MCQs) and Computer-based Case Simulations (CCS). It is a two-day exam in which you will be tested on the Foundations of Independent Practice (FIP) on the first day and Advanced Clinical Medicine (ACM) on the second.

You can increase your break time by finishing the block or the optional tutorial before time.
