This paper describes the oral assessment activity we designed and used as a culminating activity for faculty participants in a professional academic development program. The program offers multiple certificates, and the goal of each certificate is to enhance participants' abilities to design and deliver exceptional student learning experiences. We describe the unique nature of the assessment activity and provide details on the process of implementing oral assessment. This process enabled faculty to demonstrate achievement of the program learning outcomes and consider next steps in their professional development. Three key ideas discussed in this paper are: oral assessment, folio thinking, and dialogic curriculum.
