The Relationship between the Bracken Basic Concept Scale and the Differential Ability Scales with a Preschool Sample

This study investigated the relationship between the Bracken Basic Concept Scale (BBCS) and the Differential Ability Scales (DAS) in a sample of 60 preschool children between the ages of 3 years 6 months, and 5 years 11 months from Indiana and Oklahoma. A high relationship (r = .80) was found between the BBCS Total Test score and the DAS General Conceptual Ability (GCA) score. This high relationship indicates that the two measures assess similar skills, but is not high enough to warrant substitution of one for the other. A strong correlation also was found between the School Readiness Composite on the BBCS and the DAS GCA.
