Replies to comments by R. J. Griffore and D. A. Newman et al. on the author's original article on test validity and cultural bias in racial-group assessment. Helms notes that, given that within-group variance exceeds between-groups variance, racial groups are probably simulating a psychological construct that is more strongly related to individuals' test scores than to their respective racial group's mean test scores. Therefore, models of individual differences, such as her Helms individual-differences (HID) model, that remove construct-irrelevant racial variance, are needed to make the testing process fair at the level of individual African American, Latino/Latina American, and Native American test takers. Her HID model is intended to focus attention on identifying the factors responsible for the racial-group-level differences and, thereby, assist test users to look beyond presumed physical appearance (e.g., racial-group designations) for explanations of individuals' cognitive abilities, knowledge, or skills test scores.
