This study reflects on the development and implementation of mid-term oral examinations in large-scale lecture courses at a large, public research university; specifically, this work examines the implications of oral exams for fostering student engagement and concept-based comprehension in addition to institutional and course commitments to diversity. This research traces the development of an effective method for administering oral midterms and assesses the advantages and challenges of utilizing oral examinations for student assessment by detailing student feedback and TAs' reactions to administering this examination format. Findings reveal that oral examinations provided a chance for students to develop skills through a different means of engaging material and to foster a concept-based learning approach. In a discussion of student and TA reactions, this paper reports a predominantly positive assessment by both groups while noting the challenges and disadvantages of this format.
