Profile analysis of the Woodcock-Johnson III tests of cognitive abilities with gifted students



The Cattell-Horn-Carroll (CHC) factor clusters of the Woodcock-Johnson III Tests of Cognitive Abilities (WJ III COG; Woodcock, McGrew, & Mather, 2001) were studied with a group of gifted (n = 51) and nongifted individuals (n = 51). Specifically, a profile analysis was conducted using the seven CHC factors identified by the WJ III COG authors. The gifted and nongifted individuals were between the ages of 5 and 18 years, and were matched on gender, age, ethnicity, and father's level of education. Each group consisted of 23 females and 28 males. The mean age in months for the gifted group was 135.61 (SD = 48.81), and the mean age in months for the nongifted group was 134.25 (SD = 47.86). The results of the profile analysis found gifted and nongifted individuals display similar patterns of performance across the CHC factor clusters. As expected, the gifted group, on average, scored consistently higher across the set of CHC factor clusters compared to the nongifted group. In addition, no intracognitive differences were found among the CHC factor clusters for either the gifted or nongifted group. Clinical and educational considerations when using the WJ III COG when assessing giftedness are also discussed. © 2001 John Wiley & Sons, Inc.
