This study investigated the relationship between the Bracken Basic Concept Scale and the Differential Ability Scales with 35 at-risk preschoolers between the ages 3–6 and 5–11. A Pearson product-moment correlation coefficient of .70 was obtained between the Bracken Basic Concept Scale Total Test scores and the General Conceptual Ability scores of the Differential Ability Scales. This association supports the use of the Bracken scale to predict intelligence if replicated with a larger sample and specific handicaps. In addition, support for the administration of the more brief Bracken School Readiness Composite compared to using the Bracken Total Test score in the prediction of the Differential Ability Scales General Conceptual Ability score was found.
