Application of Higher-order IRT models and Hierarchical IRT models to Computerized Adaptive Testing - eScholarship

A comprehensive comparison of item selection methods and proficiency scores estimation in several multidimensional IRT models in conjunction with a CAT finds the Bayesian item selection method has smaller RMSEs and SEs than the MFI method in specific cases and the EAP scoring method outperforms the MLE method, especially for short test length in this study.
