We are receiving numerous inquiries about the small but growing online market for students' course notes, papers, etc. The Code does not prohibit selling per se, but does prohibit conduct that the student knows or should know will help others cheat. Selling or otherwise sharing work violates the Code either (1) when the instructor has PROHIBITED sharing a particular assignment, or (2) when the nature of the work and the other CIRCUMSTANCES WOULD PUT A REASONABLE STUDENT ON NOTICE that sharing will help others cheat. For example, a student who receives permission to take a test early would violate the Code by selling or otherwise posting the test before the rest of the class has taken it.
While the online format is new, the idea of selling notes and other work is old -- the first legal case we know of is from 1825! Posting work or assignments online, especially for money, can also raise copyright problems entirely separate from the academic integrity issue.
