Factor analysis was applied to the Wechsler Intelligence Scale for Children--Fourth Edition (WISC-IV) scores of 432 Pennsylvania students referred for evaluation for special education services to determine the factor structure of the WISC-IV with this population. A first-order, four-factor oblique solution that mirrored that found in the WISC-IV normative sample was supported. When transformed to an orthogonalized higher order model, the general factor accounted for the greatest amount of common (75.7%) and total (46.7%) variance. In contrast, the largest contribution by a first-order factor (Verbal Comprehension) was 6.5% of total variance. It was recommended that interpretation of the WISC-IV not discount the strong general factor. (Contains 3 tables.)
