The incremental validity of factor scores from the Wechlser Intelligence Scale for Children-III (WISC-III) in predicting scores on the Wechsler Individual Achievement Test (WIAT) was studied in 283 nonreferred children and 636 referred for evaluation. The Full Scale IQ of the WISC-III was the best predictor of WIAT achievement. (SLD)

The 10 subtests comprising the Wechsler Intelligence Scale for Children--Revised (WISC-R) were independently factor analyzed for middle (N=107) and low (N=158) socioeconomic status children. After testing for equivalence of covariance matrices between the two groups, coefficients of congruence between factors were calculated. These coefficients…

Evaluated the test bias of the Verbal IQ as measured by the Wechsler Intelligence Scale for Children-Revised in relation to predictions of academic achievement in two different socioeconomic status groups. Results indicated that Verbal IQs are not biased with respect to socioeconomic status. (Author)

Investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test using the factor scores of the Wechsler Intelligence Scale for Children-Revised as potential predictors. Results indicated that the freedom from distractibility factor score significantly aided in the prediction of reading and spelling…

Although Verbal IQ of the Wechsler Intelligence Scale for Children predicts statistically distinct Wide Range Achievement Test Reading scores dependent on the sex of the child, the differences are of little practical importance. (Author)
