The aim of the present investigation was to explore the factor structure of the WISC-R for a sample of children identified as learning disabled. The sample of 140 children were between the ages of 6–2 and 14–8 (M = 9–7); 96 were males and 44 females. A principal factor analysis yielded a factor solution similar to that reported for the WISC-R standardization sample. Support for the robustness of the Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility factors for this population of learning disabled children resulted.
