Evidence is provided on faculty use of cheating deterrents for in-class exams. The evidence comes from a survey of students who report on their most recent in-class exam in a randomly selected course that they are taking. Three types of cheating are considered: (i) advance knowledge of exam questions; (ii) copying; and (iii) other improper student actions during the exam. The deterrents examined consist of the following: (i) a rate of repeating questions; (ii) multiple versions of the exam and seating arrangements; and (iii) monitoring. The sample size is small but may cover about one-fourth of the faculty at the institution at which the survey was conducted.
