The conference theme will focus on assessment, particularly within the context of a competency-based curriculum. Assessing clinical reasoning, communication and professionalism present challenges that differ from those focused on assessing technical skills. Together, we will consider questions such as: What approaches are most successful for teaching “invisible” skills such as professionalism and clinical reasoning? When students’ performance does not meet expectations, what sorts of remediation are most effective? How much is enough, and are the results reliable? What biases underlie assessment of these more complex skills? Are some formats better than others? Are there (or what are) the tensions between global ratings, checklists, and formative or summative feedback? Keynote speakers will address these and related topics to stimulate our thinking and frame continued discussion.
