Controlling construct-irrelevant factors through computer-based testing: disengagement, anxiety, & cheating

ABSTRACT A decision of whether to move from paper-and-pencil to computer-based tests is based largely on a careful weighing of the potential benefits of a change against its costs, disadvantages, and challenges. This paper briefly discusses the trade-offs involved in making such a transition, and then focuses on a relatively unexplored benefit of computer-based tests – the control of construct-irrelevant factors that can threaten test score validity. Several unique advantages provided by computer-based tests are described, and how these advantages can be used to manage the effects of several common construct-irrelevant factors is discussed. Ultimately, the potential for expanded control may prove to be one of the most important benefits of computer-based tests
