According to research and surveys conducted by Dr. Donald McCabe and the International Center for Academic Integrity, the number of university students who admit to cheating in some form is truly eye-opening. The statistics below are just a snapshot of overall trends uncovered over the past 12 years.
Graduate Students Undergraduates*
Number responding: ~17,000 ~71,300

This basic dataset was compiled based upon surveys that were conducted between Fall 2002 and Spring 2015, by Dr. Donald McCabe and the International Center for Academic Integrity.
Furthermore, McCabe's surveys of over 70,000 high school students at over 24 high schools in the United States demonstrated that 64 percent of students admitted to cheating on a test, 58 percent admitted to plagiarism and 95 percent said they participated in some form of cheating, whether it was on a test, plagiarism or copying homework.
