Princeton University is ending its long-standing exam honor system by introducing supervision for in-person exams for the first time in more than a century, citing concerns about cheating enabled by artificial intelligence and other tools. Multiple reports say Princeton’s existing approach—allowing students to take exams without a professor present—dates to 1893, when students petitioned to remove proctors. Faculty members are said to have voted to require proctoring for all in-person exams beginning this summer. The university will still require students to affirm an honor pledge that they have not violated the Honor Code during the examination. Under the new policy, instructors are expected to be present as witnesses during exams but are instructed not to interfere with students unless needed. If a suspected violation occurs, instructors report it to a student-run honor committee for adjudication. Reports also describe concerns that the current environment makes cheating harder to detect and may discourage students from reporting misconduct due to fear of online harassment.
