This study investigated the efficacy of predicting academic achievement as measured by the WRAT, using the Verbal and Performance scores of the WISC‐R as predictors. Both tests were given to 155 children referred for psychological evaluations in a four‐county area in southeastern Nebraska, and a multiple regression analysis was conducted where the Verbal and Performance IQ scores were conjointly regressed on Reading, Spelling, and Arithmetic standard scores from the WRAT. The results indicated that the Performance IQ did not significantly predict academic achievement, and that the Verbal IQ significantly predicted only Reading and Arithmetic scores. Generated regression equations were provided.
