During the past 30 years or so, a new theoretical basis for educational and psychological testing and measurement has emerged. It has been variously referred to as latent trait theory, item characteristic curve theory, and, more recently, item response theory (IRT). Although this new test theory holds considerable promise as a successor to classical test theory, it has been underutilized by test practitioners. One important reason for this underutilization is that many test developers have not…
