Workplace-Based Entrustment Scales for the Core EPAs: A Multisite Comparison of Validity Evidence for Two Proposed Instruments Using Structured Vignettes and Trained Raters.

Purpose: In undergraduate medical education (UME), competency-based medical education has been operationalized through the 13 Core Entrustable Professional Activities for Entering Residency (Core EPAs). Direct observation in the workplace using rigorous, valid, reliable measures is required to inform summative decisions about graduates' readiness for residency. The purpose of this study is to investigate the validity evidence of 2 proposed workplace-based entrustment scales.
