Do the Steps have to be taken at particular points during my medical education and career?
You must pass Step 1 and Step 2 before you are eligible to take Step 3. In LCME-accredited medical schools, although Step 1 and Step 2 can be taken in any order, most students will take Step 1 at the end of their second year and Step 2 in their fourth year; Step 3 is usually taken during the first or second year of postgraduate training. Students and graduates of medical schools outside the United States and Canada should contact the ECFMG for information on ECFMG certification and Step 1 and Step 2 eligibility.
Most medical licensing authorities require completion of USMLE Steps 1, 2, and 3 within a seven-year period, which begins when you pass your first Step. Check the FSMB website for further information on such requirements.
