Evaluation of DTF and DIF in Two-Dimensional IRT [electronic resource] / T. C. Oshima and Others.

In 1992 N. S. Raju and others proposed a general procedure for assessing differential test functioning (DTF) and item bias (differential item functioning or DIF) in tests developed with unidimensional, multidimensional, or polytomous item response theory (IRT) models. The purpose of this paper is to...
