The purpose of this study was to determine if distinct subgroups of high achieving children could be identified using a recently redeveloped intelligence measure—The Woodcock-Johnson Tests of Cognitive Ability, 3rd edition (WJ-III). Students were referred for further testing based on their scores on the Indiana State Test of Educational Progress (the ISTEP+). Students were included in the study if they scored at or above the 90th percentile on the ISTEP+ Cognitive Skills Index, or the reading and/or math portions. Using these criteria, 202 students were referred for further testing. These students were clustered with Ward's method of cluster analysis using their scores on the seven CHC factors of the WJ-III. Their individual scores on two other intelligence measures (the Stanford-Binet IV and the Kaufman Brief Intelligence Test), as well as other scores from the WJ-III were used to further describe the clusters that emerged. The following three subgroups were identified: (a) decidedly gifted, (b) problem solvers, and (c) slow-paced achievers. Not all subgroups obtained the gifted score ranges expected on the three measures employed. The clusters were better described as displaying a slight levels effect, in that the groups were most different from one another in terms of the overall intelligence quotient and mean CHC factor scores, with one group scoring in the superior to high average ranges, one in the high average to average ranges, and one in the average range overall. This study provided evidence for the use of intelligence measures in describing gifted individuals' specific strengths and weaknesses. It also has significant implications for the use of intelligence measures in assessing giftedness within an applied setting. This study is useful as a validation study for the three intelligence measures employed. / Department of Educational Psychology
