When writing an assignment, most students start by searching for information online, which they integrate in their writing and conclude by producing a bibliography for the sources used. They use their informational, writing and referencing skills to do this as well as refer to their plagiarism knowledge to make sure their text is exempt from plagiarism. In this paper, we examined which skills and knowledge students feel the need to further develop in university to prevent plagiarism in their assignments. Professors were also questioned as to their perceptions of their students' skills development during their pre-university studies. Questionnaires were administered in six Quebec Universities to students (n = 1170) and professors (n = 279). Results show that students feel the need for more training while professors expect students to have already mastered the skills and knowledge to prevent plagiarism. Recommendations are made on how to implement better training for students through a program approach.
