โœฆ Synopsis

Revised (WPPSI-R) scores obtained prior to enrollment in kindergarten are used to predict academic achievement scores on the Comprehensive Testing Program 111 at the end of grades 1, 2, and 3. Correlations between achievement and Verbal IQ are significant at all three grade levels, with measures of vocabulary, general knowledge, and verbal concept formation (Similarities) being the most consistent verbal predictors of academic achievement. Performance IQ is a poor predictor of academic achievement, with only 3 out of 16 correlations with achievement reaching significance.

The Full Scale I Q s correlations with achievement appear to be due to the contributions of the verbal scale. Results are discussed in terms of their generalizability for this middle-and upper-middle-class sample engaged in a demanding academically-oriented curriculum.

Other studies have shown the relationship between the WISC and standardized tests of achievement. Mussen, Dean, and Rosenberg (1952) found moderate correlations between the WISC and the Metropolitan Tests of Reading and Arithmetic and the Stanford Reading and Arithmetic Tests. Stroud, Elommers, and
