Relation of scores on WISC-III and WRAT-3 for a sample of referred children and youth.
This investigation compared the Wechsler Intelligence Scale for Children-III with the Wide Range Achievement Test-3 for a sample of 60 children and youth who were referred for special education services. Pearson product-moment correlations for the criterion measures for the WRAT-3 showed a significant positive association with the WISC-III scores. Implications for concurrent validity between the tests are discussed.
