If you suspect a student of cheating, speak with the course supervisor before confronting the student yourself. Make-Up Exams Students should contact you before the actual exam. If possible, make the student take the exam early. That way if there is communication between the student and the other classmates, the student won't be the beneficiary. If a student is taking a make-up exam after the rest of the class, use an exam given in a different section of the same course.
Some instructors stongly discourage make-up exams by offering an unattractive alternative.
You will sometimes be approached by a student who missed an exam and did not notify you by the date required on your syllabus or who has an excuse you feel is less than legitimate or honest. While you may feel the student does not deserve a make-up exam, it is often better to give the exam and not allow the student to blame you for a poor course grade. Students in these situations seldom perform well on the exam and will earn a low grade all on their own. Report the incident to the course supervisor before taking any action on your own, e.g., before confronting the student yourself. The academic dishonesty section of the Iowa State University Bulletin outlines the steps that all instructors are to follow if they suspect a student of cheating.
