The McCarthy scales of Children's Abilities as a predictor of achievement: A five-year follow-up

Abstract

The purpose of the present study was to determine if the McCarthy Scales of Children's Abilities could be utilized as a predictor of achievement over a six-year period. Twenty-four kindergarten children were tested with the McCarthy Scales and subsequently examined with the Comprehensive Testing Program achievement tests in sixth grade. A correlational analysis of the data resulted in significant relationships between the McCarthy General Cognitive Index, Quantitative Scale, and Memory Scale and both the CTP and course grades. The McCarthy Perceptual-Performance Scale showed significant correlations with the CTP but not with course grades; the Verbal Scale was not predictive of academic achievement. The significance of these findings is discussed.
