An R Package for Simulating Computerized Adaptive Tests (CATs)


catIrt provides methods for simulating Computerized Adaptive Tests, including response simulation, item selection methods, ability estimation methods, and test termination methods. Unique in catIrt is support for the graded response model (and, soon, other polytomous models) along with expanding support for classification CAT (including an implementation of the SPRT, GLR, and CI methods).
