This study examined correlations between WISC‐R and K‐ABC subtests in a sample of 101 children referred for learning disabilities. A considerable overlap between the two instruments was found. Separate factor analyses of the WISC‐R and K‐ABC were conducted. By and large, the WISC‐R factor structure was similar to that found for standardization samples. Three factors emerged, namely Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility. In line with earlier findings, the K‐ABC factor analysis resulted in two factors: Simultaneous and Sequential Processing. A shorter battery combining subtests from both instruments is discussed. © 1998 John Wiley & Sons, Inc. J Clin Psychol 54: 1053–1061, 1998.
