Computerized Adaptive Testing: A Comparison of the Nominal Response Model and the Three Parameter Logistic Model.
PDF on ERIC Download full text
DeAyala, R. J.; Koch, William R. – 1987
A nominal response model-based computerized adaptive testing procedure (nominal CAT) was implemented using simulated data. Ability estimates from the nominal CAT were compared to those from a CAT based upon the three-parameter logistic model (3PL CAT). Furthermore, estimates from both CAT procedures were compared with the known true abilities used…
