As you all know, ECFMG has already eliminated the 2-digit scores and replaced it by the 3-digit scores which is more reflective of the applicant performance at any test. As per August 2013 the minimum passing scores for the USMLE tests are as following:
USMLE Step 1: 188
USMLE Step 2 CK: 203
USMLE Step 2 CS: Pass
USMLE Step 3: 190
These numbers are subject to change depending on research and other stuff the board conducts. We will hopefully keep you posted about any change. We wish you the best in your USMLE journey.
