Abstract
The Differential Ability Scales (DAS) and the Woodcock-Johnson Tests of Cog nitive Ability- Revised (WJ-R COG standard battery) were administered to 81 children referred for special education services evaluation. Both the Gene ral Conceptual Ability (GCA) and the Nonverbal Reasoning scores of the DAS were significantly lower than the WJ-R COG Broad Cognitive Ability-Standard score (BCA-STD). The DAS Verbal and Spatial Composite scores were not sign ificantly different from the BCA-STD. Low to moderate correlations were fou nd between related constructs on the two tests.
