Validation of a WISC-III Short Form for Canadian Students With Learning Disabilities

Abstract

WISC-III subtests scores from 44 students referred for special education evaluations and identified as having learning disabilities were used to compute WISC-III short form IQs based on.the Dumont/Faro formula. The resultant short form IQs for Canadian students, scored using United States norms, were compared with the scores obtained from the complete WISC-III. Misclassification indexes were computed. This article discusses the composition of the WISC-III short form, its utility for Canadian children, and guidelines for apprapriate use.
