The United States Medical Licensing Examination (USMLE) is a three-step examination process for medical licensure in the United States. It assesses a physician's ability to apply knowledge, concepts, and principles important for effective patient care. The exam is designed for medical students and graduates who wish to practice medicine in the U.S. The three steps of the USMLE include Step 1, which tests basic medical sciences; Step 2, which evaluates clinical knowledge and skills; and Step 3, which assesses the ability to manage patients in a clinical setting. Passing all three steps is required to obtain a medical license in the U.S.
