A Comparison of the Nominal Response Model and the Three-Parameter Logistic Model in Computerized Adaptive Testing.

De Ayala, R. J.

Educational and Psychological Measurement, v49 n4 p789-805 Win 1989

A polychotomous nominal response model-based computerized adaptive test (CAT) was simulated using data from 1,093 University of Texas students. The ability estimation of this model and its overall performance were compared with those of a dichotomous three-parameter logistic model-based CAT. Advantages and drawbacks of nominal response CAT are described. (SLD)
