In a classroom situation a teacher can monitor students and visually uphold a level of integrity consistent with an institution's reputation. However, with distance education the student can be removed from supervision completely. Distance education has long had trouble with testing. The delivery of testing materials is fairly straightforward, which makes sure it is available to the student and he or she can read it at their leisure. The problem arises when the student is required to complete assignments and testing. Online courses have had difficulty controlling cheating in quizzes, tests, or examinations because of the lack of teacher control.
