The USMLE (United States Medical Licensing Examination) is a multi-step examination required for medical licensure in the United States. It assesses a physician’s ability to apply knowledge, concepts, and principles essential for effective patient care. The exam is divided into Step 1, Step 2 CK (Clinical Knowledge), and Step 3. Each step evaluates progressively more advanced clinical and scientific skills. The exam is administered by the NBME and FSMB, and candidates must meet specific eligibility criteria, including being enrolled in or a graduate of a medical school listed in the World Directory of Medical Schools.
