Applicants must have passed steps 1, 2 and 3 within three attempts. Four attempts are allowed if currently licensed in another state and currently certified by a specialty board of ABMS, AOABPE, RCPSC, or CFPC. USMLE Step 3 must be passed within 5 years of Step 2 or before the end of residency training. Applicants must pass each step with passing scores as recommended by the USMLE program. Combinations of FLEX, National Board, and USMLE (as outlined in the USMLE bulletin) may be accepted by the Board as comparable to existing exam sequences, but all exams must be passed within three attempts and completed prior to the year 2000
