·The ACGME has developed educational milestones for the assessment of trainee progress in anesthesiology residency and fellowship training programs.

·Entrustable Professional Activities (EPAs) are clinical activities that may be entrusted to a trainee and, when implemented as the basis of clinical assessment, provide a bridge connecting trainee performance to educational milestones.

·Here, we describe the preliminary results of the first five months of a multi-center pilot study observing the implementation of EPAs for the assessment of RAAPM fellows in the United States.
