An academic committee is reviewing pedagogical methods across undergraduate institutions. Draft a report critically assessing the fitness of conventional letter-grade systems (A, B, C) in measuring complex, interdisciplinary learning outcomes. Present a personal argument for or against the adoption of narrative feedback or mastery-based grading, and propose three challenges for discussion regarding the standardization and portability of alternative academic credentials. The report should be titled: The Obsolescence of Traditional Grading: A Case for Holistic Assessment Models.
