Princeton Ends 133-Year Unproctored Exam Tradition Amid AI Cheating Concerns

Princeton University has voted to end its historic 133-year-old Honor Code system of unproctored examinations, requiring faculty proctoring for all in-person exams starting this summer. The decision responds to a significant rise in academic dishonesty linked to the widespread availability of generative AI tools since late 2022. Data from the university’s Committee on Discipline shows an increase in students found responsible for violations, rising from 50 in the 2021–22 academic year to 82 in 2024–25. A campus survey further revealed that 30% of graduating seniors admitted to cheating, while 28% acknowledged using ChatGPT on prohibited assignments. Dean Michael Gordin noted that AI has made cheating easier and detection harder, while also creating a culture where students fear social backlash for reporting peers. Although the traditional honor pledge remains mandatory, trust alone is no longer considered sufficient safeguard. This policy shift marks a major departure from Princeton’s long-standing philosophy that treating students as honorable encourages honorable behavior, reflecting broader challenges higher education institutions face in adapting to artificial intelligence.
