The U.S. Medical Licensing Exam

The U.S. Medical Licensing Exam (USMLE) is a three-step examination for medical licensure in the United States. The USMLE assesses a physician's ability to apply knowledge, concepts, and principles while demonstrating fundamental patient-centered skills that constitute the basis of safe and effective medical care. Step 1and Step 2 are only applicable to medical students. Step 3 is for residents.

Step 1

Assesses whether the student understands and can apply concepts of science that are basic to the practice of medicine.

Step 3

Content

Step 3 is only applicable to graduating medical residents. Unsupervised clinical encounters (initial, continued, and emergency care scenarios) and physician tasks, including:

  • History taking
  • Physical exam
  • Diagnostic studies
  • Formulating a diagnosis
  • Severity evaluation
  • Identifying disease mechanisms
  • Patient management

Format

Step 3 examinees are tested using multiple-choice questions and Primum computer-based case simulations (CCS). During the CCS portion, the examinee provides care for a simulated patient and the computer records each step taken in caring for the patient and scores the examinee's overall performance.

As simulated time passes, the patient's condition changes based on the underlying problem and examinee interventions. The patient's simulated chart facilitates review of vital signs, progress notes, patient updates, and test results.
