Students Cheating With AI Caused This Ivy League School to Overturn a 133-Year-Old Tradition

Princeton University will require human proctors for exams starting July 1, ending its 133-year no-proctoring tradition.

The change is aimed at curbing AI-assisted cheating, which faculty say has become easier to hide on personal devices.

Reports of misconduct have become less frequent and often anonymous, making violations harder to detect and enforce.

The policy marks Princeton’s biggest honor-system change since 1893 and reflects a broader shift in higher education toward tighter oversight.
