Description
Summary:This study compared differences in performance on the WISC‐III and on the WISC‐R. Sixty‐one students with learning impairments, due for reevaluation of their special education placement, were administered the WISC‐III as part of a psychological assessment battery. Results indicate a mean difference between WISC‐R and WISC‐III FSIQ of 7.95 points, which is similar to WISC/WISC‐R comparisons. Substantial differences that averaged 9.21 points were found between WISC‐R and WISC‐III PIQ means. These findings suggest that for a special education sample an average decrease of at least 8 points can be expected on the WISC‐III Full Scale IQ. Caution should be exercised when one is considering changes in educational classification or interpreting qualitative differences in performance on WISC‐III scores compared with WISC‐R scores.
