The problem of test bias has been a growing concern in recent years. Of the several available methods for determining test bias, probably the most effective means involves collecting criterion information. This data collection process often provides a considerable barrier to the researcher, especially for the small test user and for someone who needs an immediate solution to a test bias question. This paper presents a method for identifying and analyzing the nature of test bias. This method is intended as only a preliminary analysis prior to, or concurrently to, a criterion data collection process. (Author)
