Abstract

Using simulations, this study investigated how attribute balancing affects test efficiency in fixedlength and fixed-precision computerized adaptive testing with cognitive diagnosis models. It was found that attribute balancing had different effects on test efficiency for different item selection methods and termination criteria.
