Princeton University is set to change its long-standing policy of unproctored exams, which has been in place since the establishment of its honor code in 1893. Starting this summer, all in-person exams will be proctored due to a significant rise in cheating incidents, particularly facilitated by AI tools. A recent survey indicated that nearly 30% of Princeton seniors admitted to cheating at some point during their academic careers, with 45% aware of unreported violations. The shift was approved by faculty following concerns from both students and faculty regarding the integrity of the examination process. Dean Michael Gordin emphasized that the ease of cheating, coupled with a reluctance among students to report violations, necessitated this change. Under the new rules, professors will oversee exams and report any suspected cheating to the student honor committee. This move aims to restore trust in the academic environment while maintaining the honor code's essence.
