Abstract
This study examined the relationship between the Canadian Cognitive Abilities Test (CCAT) and the Wechsler Intelligence Scale for Children - Third Edition (WISC-III) using archival data pertaining to a sample of 279 students with learning difficulties. A significant correlation (r =.43) was found between the CCAT Composite Standard Age Score (SAS) and WISC-III Full Scale IQ. Significant correlations between Verbal and Nonverbal CCAT SASs and WISC-III Verbal and Performance IQs were .35 and .42, respectively. Significant correlations between Verbal, Nonverbal, and Quantitative CCAT SASs and corresponding WISC-111 Index scores were .31, .43, and .31. WISC-111 mean IQ/Index scores were significantly higher than CCAT mean SASs for composite, verbal and nonverbal comparisons, while the CCAT Quantitative SAS mean did not differ significantly from the WISC-III Freedom from Distractibility Index mean. Discrepancies between participants' CCAT and WISC-III composite scores are reported. Directions for future research and implications for practice are discussed.
