Trends in plagiarism and cheating prevalence: 1990-2020 and beyond

Research output: Chapter in Book/Conference paperChapterpeer-review


Are students cheating and plagiarizing more or less than they used to? The best available evidence, which allows for like-with-like comparisons, suggests that the prevalence of plagiarism and cheating among students trended downward in the 30 years from 1990 to 2020. In addition, there is not clear evidence that students replaced copy-and-paste plagiarism with a corresponding increase in commercial contract cheating. Targeted educational, technological, and policy interventions to reduce plagiarism and cheating, which have become more common, may account for the downward trend. Still, the downward trend in plagiarism and cheating prevalence faces emerging threats.
