Comparison of the K—ABC Achievement Scale and Wppsi IQs of Preschool Children

Abstract

The correlations of individual subtest with scale scores of the Kaufman Assessment Battery for Children (K—ABC) and the three IQs yielded by the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) were examined. This study was undertaken as an initial investigation designed to determine the utility of the K-ABC Achievement Scale as an independent measure of achievement in preschool children. Achievement scale scores and WPPSI IQs were obtained from a sample of 34 preschool children ages 48 to 60 mo. Strong, positive relations between the K—ABC Vocabulary and Total Achievement Scale score and WPPSI Verbal and Full Scale IQs were noted. Moderate correlations were obtained between the scores of the Riddles and Faces and Places subtests and the WPPSI Verbal, Performance, and Full Scale IQs. Low correlations were found between the Arithmetic subtest and WPPSI Verbal, Performance, and Full Scale IQs. The utility of the K—ABC achievement subtests as a standardized measure of preschool achievement was discussed.
