A study was conducted in California to explore the extent of cheating, its relationship to personal and situational factors, and the actions of school personnel to promote academic honesty and responsibility. Questionnaires were completed by 1,037 sixth-graders, 2,265 secondary school students (mostly 11th-graders), and 109 school staff members. Forty-five elementary schools and 105 high schools were sampled, representing the lowest, middle, and highest scores on the California Assessment Program's mathematics tests. The three questionnaires are presented, with a summary of responses to each item. The results indicated that the reported incidence of cheating was much higher among high school students than sixth-graders. Sixth-graders most often reported copying on tests and plagiarizing. High school students reported use of crib notes and copying during tests. About 93 percent of high school students reported seeing other students cheating on tests more than once. More cheating was reported by students from high-scoring schools, and students with lower grades cheated more. School staff reporting that cheating was a significant problem included 41 percent of secondary school staff and 3 percent in elementary schools. Appendices include the questionnaires and percentile responses. (GDC)
