Abstract:Methods for detecting copying of multiple-choice test responses developed over a 60-year period are reviewed and compared with respect to their effectiveness and the practicality of their application for groups of varying size. Although effective detection methods are routinely used in large admissions and licensing testing programs, they are seldom applied in the areas of standardized testing or classroom testing in schools or colleges. Circumstances associated with this discrepancy are discussed.
