It was recently announced that starting July 1, 2011, USMLE would begin the process of eliminating the reporting of results on the 2-digit score scale to all score users except the examinee and the state licensing authority to whom results are reported at the examinee’s request.
Other users of USMLE results who have focused on the 2-digit score scale in the past will need to transition to using the 3-digit score. A table that will allow users to look up the 3-digit score(s) that corresponds approximately to a specific 2-digit score on recently administered Step 1 (since January 2010) and Step 2 CK (since July 1, 2010) examinations has been posted on the USMLE website. This table will not apply for results reported October 1, 2011 and later.
