Starting in early August, 2012, the number of items on the Step 2 Clinical Knowledge (CK) examination will change. Although the change will occur quickly at many test centers, there may be some locations where this takes longer to complete. The overall transition period should last approximately 6 weeks.
Score reports for Step 2 CK are usually available within four weeks of testing. However, because of the change described above, as well as routine modifications to the test item pool, score reporting for most Step 2 CK examinations administered in August will take longer. The target date for reporting Step 2 CK scores for most examinees testing in August is Wednesday, September 26, 2012.
Examinees should read the full announcement on the USMLE website.
