Investigations of item bias provide an empirical basis for the identification and elimination of items appearing to measure different traits across population/culture groups. This paper reviews the psychometric rationales of six types of approaches to biased item identification. (Author/JKS)

In this paper an approach to biased item identification using ICC theory is described and applied. The ICC theory approach is attractive in that…

Transformed item difficulties, chi-square, item characteristic curve (icc) theory and factor score techniques were evaluated as approaches for the identification of biased test items. The study was implemented to determine whether the approaches would provide identical classifications of items as to degree of aberrance for culturally different…

Investigations into item bias provide an empirical basis for the identification and elimination of test items which appear to measure different traits across populations or cultural groups.
