Abstract

Predictive validity of the Wechsler Intelligence Scale for Children-Revised was investigated across race for 174 Chicano and 94 Anglo children referred for psychological services. Regression lines for the prediction of achievement were compared across race through the Potthoff analysis, which provides a simultaneous test of slope and intercept values. Results of these comparisons generally supported the predictive validity of the WISC-R across race with this referral sample of young children.
