Colleges and universities across the nation have decided to do more than talk about the rise in student cheating. For instance, the Department of Psychology at the University of Maryland launched a campaign to stop one form of cheating. As 409 students filed out of their exam, they found all but one exit blocked. Proctors asked each student to produce an ID card with an attached photo. Students who said they’d left theirs in the dorm or at home had a mug shot taken. The purpose of the campaign was to catch “ringers,” students who take tests for other students.
