USMLE
United States Medical Licensing Examination
The three-step pathway to medical licensure and residency in the United States.
About the exam
The USMLE assesses whether you can apply medical knowledge safely in patient care. Step 1 is now pass/fail, which has shifted residency selection weight onto Step 2 CK, research, clinical experience and letters.
International graduates apply through ECFMG certification, so the exam calendar has to be planned backwards from the residency Match timeline.
