Evaluation is essential throughout the development of entrustable professional activities (EPAs) to ensure that the resource-intensive work required in EPA development leads to a set (or framework) of EPAs that are fit for their intended purpose. This chapter draws on program evaluation literature to show how EPA core team leaders can conceptualize evaluation as part of the EPA development process. It then covers key evaluation strategies relevant to different stages in EPA development, piloting, and implementation. In addition, an in-depth discussion of the purpose and use of the EQual rubric for evaluating individual EPA quality is provided.
