This study examines how the self-reported cheating behaviors of students from a single large institution serving primarily adult students in online courses differ from those previously reported in large-scale studies of academic integrity among traditional-age college students. Specifically, the research presented here demonstrates that students at a large online university are no more likely to engage in most forms of cheating than the traditional-age students in residential institutions studied by Donald McCabe in his seminal research on academic integrity. Relatedly, our study finds that students' age decreases the likelihood of engaging in cheating behaviors. Moreover, traditional-age undergraduates in our study were no more likely to engage in cheating behaviors than the undergraduate students McCabe surveyed. Our study offers a unique contribution to the extant literature on academic integrity, as we believe this is the largest survey of student attitudes, beliefs, and behaviors from a single institution. The research presented here confounds the common (mis)perception that cheating is more prevalent and easier to accomplish in online learning and assessment.
