An undergraduate course required for graduation has a reputation for being extremely hard to pass, much harder than similar courses. When posting materials to the class website, the teacher accidentally posts a test with answers indicated at the end. The teacher notices the error immediately and deletes the test, but before she does so, a student downloads it. The website does not allow the teacher to see whether the test was downloaded and because she deleted the test with the answers so quickly, the teacher later uploaded the same test without the answers and required students to take the test. The Student Code of Ethics prohibits students from taking a test when there is a reason for them to believe they have confidential information regarding the answers to a test they are not supposed to have. Violations of the Student Code of Ethics are punishable.

What are the issues of integrity, ethics, and law posed in the case study? What options do the teacher and the student have, and what should they doo and why?
