A new version of the software used to deliver the computer-based USMLE Step examinations is scheduled to be introduced in mid-August 2008. Migration to the new version will occur first in the Step 2 Clinical Knowledge (CK) examination, and will be phased in over several weeks. If you plan to take the Step 2 CK examination in August 2008 or later, you should familiarize yourself with both the current test delivery software and the new version.

Orientation and practice materials using both the current and new versions of the software are available for downloading:

The change to the test delivery software will be accounted for in scoring the examination results, so that scores will be comparable to those of exams using the older software. Because of this change, it will be necessary to delay the reporting of scores for some examinees. The normal turnaround time for reporting scores to Step 2 CK examinees is 3 to 4 weeks. However, during this transition, turnaround time may be as long as 6 to 8 weeks.

Note to Step 1 and Step 3 examinees: Migration of Step 1 and Step 3 to the new test delivery software will occur in 2009. Please monitor the USMLE website announcements section to check for changes in test delivery software, and to access orientation and practice materials.
