A literature review: Entrustable professional activities, an assessment tool for postgraduate dental training?

Assessing when dental trainees are ready to independently undertake clinical procedures at specialist level is critical for dental postgraduate programmes to determine when a trainee is 'work ready', in addition to ensuring patient safety. Entrustable professional activities (EPA) are a novel method of competency-based assessment. An EPA is a unit of professional practice or critical clinical activity identified within dental training programmes, which should be assessed during training, to establish if trainees are ready for independent practice, with a progressive decrease in supervision, based on supervisors' entrustment decisions.
