Assessment is a central feature of teaching and learning. It is both complex and challenging in ordinary times, and these aspects are magnified in an online learning environment. Given its central role, it is crucial that its design and purpose is rigorous and robust. This paper presents justification for using interactive oral assessment as an online, innovative, authentic assessment approach that prepares students for professional life, combats plagiarism and promotes academic integrity. It shares findings through four brief case study examples of using interactive oral assessments in computing, education, French literature, and aviation. This study also demonstrates the value of a Community of Practice in developing expertise, confidence, and resources to support the effective application of interactive oral assessment.
