The purpose of this study was to assess student perceptions of self-plagiarism. Students at three university campuses offering graduate and undergraduate classes in a residential and online format were queried; 284 students responded. Overwhelmingly, students perceived they owned their own previous published works and over half reported they believed self-plagiarism should not be considered an academic honesty offense. Most faculty members did not provide information about self-plagiarism to their students. Only about one-fourth of the students reported recycling parts of an assignment in the past. Students who took online courses were more likely to have been educated about self-plagiarism than those who took residential courses. Understanding students' perceptions about academic honesty offenses such as plagiarism can help institutions develop effective policies and interventions.
