Peer reviewedLee, Guemin; Dunbar, Stephen B.; Frisbie, David A. – Educational and Psychological Measurement, 2001
Conceptualized eight different types of measurement models for a test composed of testlets and studied the goodness of fit of those models to data using data from the Iowa Tests of Basic Skills and simulated data. The essentially tau-equivalent model and the congeneric model provided worse model fit than the other measurement models. (SLD)
