SINCE early in the history of objective or &dquo;new-type&dquo; tests, users of them have been concerned with their peculiar susceptability to cheating (Bird, 1927). Perhaps the most widely used, and certainly the most widely recommended, type of these tests is the multiple-choice variety in its several forms, and one of the more common forms of cheating occurs when a student copies answers from one or more of his neighbors in the testing situation.
