| Abstract: | The Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; Wechsler, 1997) permits the calculation of both traditional IQ and Index scores. The Verbal Comprehension and Perceptual Organization indexes are the most highly "g" loaded compared to the Working Memory and Processing Speed indexes that may be more sensitive to some neuro-cognitive disorders. In certain clinical situations, a general ability composite score based on the combination of only the verbal and performance indexes is desirable. Following the procedure for calculating a General Ability Index (GAI; Prifitera, Weiss, & Saklofske, 1998) for the Wechsler Intelligence Scale for Children-Third Edition (WISC-HI; Wechsler, 1991) and the WAIS-III (Tulsky, Saklofske, Wilkins, & Weiss, 2001), GAI normative tables for the WAIS-III Canadian standardization sample are reported here to complement earlier published GAI Canadian norms tables for the WISC-III.
