From 2007 through 2012, the NBME team reviewed literature in physician–patient communication, examined performance characteristics of the Step 2 CS exam, observed case development and quality assurance processes, interviewed SPs and their trainers, and reviewed video recordings of examinee–SP interactions.  The authors describe perspectives gained by their team from the review process and outline the resulting enhancements to the Step 2 CS exam, some of which were rolled out in June 2012.
