Want to know what’s covered on the USMLE Step exams? Review the USMLE Content Outline and the USMLE Physician Tasks/Competencies documents.
The USMLE Content Outline is an important resource that includes a complete description of the concepts and principles examinees are responsible for knowing for the USMLE Step exams. The USMLE Physician Tasks/Competencies provides an outline of the tasks and competencies assessed throughout the sequence of USMLE examinations.
