While much work has been done on identifying and measuring the incidence of plagiarism in coursework, very little is known about the plagiarists themselves, and it is this issue that we address in this article. A model, developed to determine the factors that lead students to plagiarize, indicates that males are more likely to cheat than females, and those with higher entrance qualifications are less likely. Other factors correlated with cheating were the rate at which the course work was completed, and the number of attempts needed to solve the problems; those who submitted their work early, and those who took fewer attempts to solve the problems, were less likely to cheat.
