In spite of massive research efforts, no clear conclusions have been reached with regard to whether specific exceptional groups demonstrate Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles that reliably differentiate them from normative or other exceptional groups. This study applied multivariate clustering and profile analysis procedures to the Kaufman-recategorized WISC-R subtest data of 119 samples of normal and exceptional children drawn from the available WISC-R research literature in an attempt to determine whether some limited number of WISC-R patterns adequately describe the performance of these children and the extent to which such performance patterns may be associated with psychoeducational diagnosis or level of intellect. This meta-exploration showed the performance of the 119 samples to be most parsimoniously described by three relatively distinct recategorized WISC-R profiles. Profile similarity appeared to be most strongly related to the mean Full Scale IQ of the samples. Samples failed to cluster as a function of psychoeducational diagnosis. These results suggest that the use of WISC-R profile analysis for the differentiation of various diagnostic groups is not warranted. Twenty-six pages of bibliographical references as well as data tables are appended. (Author/JAZ)
