title: Assessment of mentally retarded children with the Kaufman Assessment Battery for Children.
abstract: The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Kaufman Assessment Battery for Children (K-ABC) were compared using a sample of 37 mentally retarded children (mean age = 9.75 years). The predictive validity of these instruments was examined using the Peabody Individual Achievement Test, administered 7 months later, as a criterion measure of achievement. Results revealed that the WISC-R Full Scale IQ (57.8) was significantly lower, p less than .001, than the K-ABC Mental Processing Composite (65.1). The WISC-R Verbal and Full Scale IQs correlated highly with the K-ABC Achievement Scale, which was the best predictor of PIAT Total Test scores. Implications for use of the K-ABC and WISC-R were presented.
