This study investigated the differential validity of the Wide Range Intelligence Test, which is a new, brief measure of ability. Participants (N = 744) ranged in age from 5 through 85 years (M = 26.7 years, SD = 21.4 years) and varied by the demographic variables of gender, race/ethnicity (Anglo, African American, Hispanic), and education level (less than high school degree, high school degree, some postsecondary training, college and beyond). General, Verbal, and Visual IQs from the WRIT were used to predict Reading, Mathematics, and Spelling criteria on the Wide Range Achievement Test-Third Edition. Differences in prediction were evaluated among demographic subgroups via Potthoff's technique. Of the 90 simultaneous tests, 65 revealed no statistically significant between-group differences. The majority of statistically significant differences were found to have little practical influence when measures of effect size were considered. Results are discussed in the context of other ability measures that were previously investigated for differential validity, as well as educational implications for clinicians. (Contains 5 tables.)
