Abstract

The present study investigated the predictive validity of the Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale IQ relative to the Wide Range Achievement Test (WRAT) Reading, Spelling, and Arithmetic subtests as criterion measures for a group of 61 educable mentally handicapped (EMH) students in a public school setting. The results of a multivariate multiple regression analysis indicated that WISC-R Full Scale IQ did not yield valid prediction of achievement as measured by the WRAT subtests. Cautions are presented with regard to generalizing the current findings to other student populations.
