Princeton University ends 133-year-old tradition as AI cheating forces return of exam proctors

Princeton University Reinstates Exam Proctoring After 133 Years

Princeton University has made a historic decision to end its 133-year-old tradition of unproctored exams, marking the most significant change to the institution's Honor Code since its adoption in 1893. The shift comes as AI cheating has become increasingly widespread, with both faculty and students requesting the return of in-person proctors to maintain academic integrity1

. The new policy takes effect on July 1, 2025, ending an era when professors would leave examination rooms, trusting students to uphold their signed pledges not to cheat.

Michael Gordin, dean of the college at Princeton University, explained in his policy proposal that "significant numbers" of professors and students supported the change "given their perception that cheating on in-class exams has become widespread"4

. The administration's Committee of Examinations & Standing unanimously voted in April to institute proctoring, responding to concerns that generative artificial intelligence has made academic dishonesty too easy to commit and too difficult to detect.

Widespread Cheating Revealed in Student Surveys

A 2025 survey conducted by The Daily Princetonian painted a troubling picture of academic dishonesty at the prestigious institution. Approximately 30% of graduating seniors admitted to cheating on assignments or exams during their time at the university1

. Even more concerning, about 28% acknowledged using ChatGPT on assignments when it was not allowed, and 45% said they knew of cheating by peers but chose not to report it3

.

The Committee on Discipline found 82 students responsible for academic violations in the 2024-25 academic year, compared with just 50 students in 2021-223

. Despite this increase, Gordin noted there were "no significant increases in instances where individuals were called before the Honor Committee," suggesting many violations go unreported1

. Nadia Makuc, a Princeton senior and former chair of the Honor Committee, told The Wall Street Journal that the panel handled around 60 cases over the past year, but suspects many more potential violations never enter the system5

AI-Enabled Cheating Undermines Traditional Safeguards

The advent of generative artificial intelligence has fundamentally altered the landscape of academic dishonesty. Students can now access AI tools like ChatGPT on personal devices such as smartphones, making cheating harder to detect during exams1

. "If the exam is on a laptop, someone can just flip to another window," Makuc explained. "Or if the exam is in a blue book, it's just people using their phone under their desk or going to the bathroom and using it"4

.

Gordin's proposal highlighted another critical issue: students have become increasingly unwilling to report violations due to fears of retaliation via social media, including doxxing and other bullying behavior1

1

. "If students alone are present in the examination room and students are unwilling to report, then there is no check against misconduct during assessments," he wrote1

. The visibility of cheating has also increased, with students posting about Honor Code violations on Fizz, the campus's anonymous social-media app, creating an environment where honest students feel disadvantaged3

How the New System Will Work

Under the reinstated exam proctoring system, human instructors will supervise students during exams and report suspected infractions to the student-run Honor Committee for review and punishment1

. Students will still be required to sign a pledge stating "I pledge my honor that I have not violated the Honor Code during this examination," maintaining a symbolic connection to the original Honor Code tradition5

.

Makuc believes most students support the shift because it relieves them of the burden of turning in their peers5

. The change reflects what Jennifer Rubin, senior researcher at the Foundry10 education research organization, describes as "a broader pattern we're seeing across education: institutions turning to increased oversight when existing norms feel inadequate"1

Broader Implications for Higher Education

Princeton University is not alone in confronting the challenges posed by AI-enabled cheating. Duke University ceased giving numerical ratings to student essays in 2024 as part of the admissions process, with Christoph Guttentag, Duke's dean of undergraduate admissions, noting that the university could no longer assume essays are accurate reflections of candidates1

1

. Many schools have implemented AI detection tools and established strict rules on AI use, with nearly half of all teachers in grades six through 12 saying they use AI detection tools regularly1

.

Rubin notes that while proctors may relieve "some of the immediate pressure" around AI cheating, institutions will need to do more to properly navigate AI and its nearly ubiquitous availability1

1

. Christian Moriarty, a professor of ethics and law at St. Petersburg College in Florida, emphasized the stakes: "At stake here is not just the soul of education, but also the genuine development of critical thinking among the population"5

. As AI tools become more sophisticated, faculty and students across higher education will need to watch how these policies evolve and whether proctoring alone can address the fundamental tensions between technological accessibility and academic integrity.
