Mexico's largest university scraps AI exam proctoring after mass failure

UNAM's decision to invalidate 58,000 exam results—roughly a third of test-takers—exposes the gap between AI proctoring vendors' claims and classroom reality, particularly in resource-constrained settings where internet reliability and device access are uneven. The failure forced a complete retake, signaling that universities betting on remote proctoring as a cost-saver are underestimating both the technical and social risks. The incident will likely slow adoption of AI exam supervision in Latin America and reinforce skepticism among administrators already wary of outsourcing assessment to opaque systems.
