This study investigates measurement decision theory (MDT) as an underlying model for computer adaptive testing when the goal is to classify examinees into one of a finite number of groups. The first analysis compares MDT with a popular item response theory model and finds little difference in terms of the percentage of correct classifications. The…

A computer adaptive test (CAT) is a delivery methodology that serves the larger goals of the assessment system in which it is embedded. A thorough analysis of the assessment system for which a CAT is being designed is critical to ensure that the delivery platform is appropriate and addresses all relevant complexities. As such, a CAT engine must be…

This report provides an overview of the current applications of computer technology to construct test items and/or to formulate tests according to sound measurement principles. The test items may be computer-generated from strategies programmed by test constructors, or pre-constructed by item writers and stored in computer memory. The tests…
