The detection of differential item functioning (DIF) is an essential step in increasing the validity of a test for all groups. The item response theory (IRT) model comparison approach has been shown to be the most flexible and powerful method for DIF detection; however, it is computationally-intensive, requiring many model-refittings. The Wald test, originally employed by Lord for DIF detection, is asymptotically equivalent to this approach and requires only one model fitting. In this research… Expand
