Abstract
A large body of literature exists describing how rater effects may be detected in rating data. In this study, we compared the flag and agreement rates for several rater effects based on calibration of a real data under two psychometric models-the Rasch rating scale model (RSM) and the Rasch testlet-based rater bundle model (RBM). The results show that the RBM provided more accurate diagnoses of rater severity and leniency than do the RSM which is based on the local independence assumption. However, the statistical indicators associated with rater centrality and inaccuracy remain consistent between these two models.
