Validity of the Woodcock-Johnson Tests of Cognitive Ability for Gifted Children: A Comparison Study with the WISC-R
In order to determine the concurrent validity of the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) in relation to the Weschler Intelligence Scale for Children-Revised (WISC-R) for elementary school children identified as gifted, and two tests were administered to 33 subjects in a counterbalanced fashion. The subjects were selected based on three factors: (1) parent and/or teacher judgments; (2) parental permission to test; and (3) a standard age score of 120 or above on a group intelligence test. Pearson Product-Moment Corelation Coefficients were calculated between all combinations of WISC-R IQ's paired with WJTCA cluster scores. A significant relationship was found to exist between the two tests’ full scale scores. Most of the WJTCA clusters correlated significantly with the WISC-R Scale IQ which suggests a high verbal loading on the WJTCA.
