Abstract
The study included a formulation of eight versions of an adaptive testing model and computer simulations used to compare the accuracy and efficiency of the versions to each other and to conventional testing modes. The adaptive testing model was designed to be applicable to the needs and problems incurred in assessing mastery/non-mastery of instructional objectives by trainees. The overall purpose was to design a testing model that could provide greater accuracy in mastery/non-mastery classifications with fewer test items than are presented with conventional tests. The study included two phases of computer-simulated tests of the models. The first phase employed Monte Carlo simulations; the second used existing data obtained from trainees in a Weapons Mechanics training course. The results of the first phase showed that one of the versions was superior in accuracy to a conventional testing procedure.
