Differential Ability Scales 2nd ed.

Obtain in-depth understanding of a student’s capabilities for effective intervention

The design of Differential Ability Scales–Second Edition (DAS-II) comes out of a vision to provide the psychologist with insight into how a child processes information to devise appropriate interventions and/or recommendations for the classroom and at home.

The DAS–II is a comprehensive, individually administered, clinical instrument for assessing the cognitive abilities that are important to learning. The test may be administered to children ages 2 years 6 months (2:6) through 17 years 11 months (17:11) across a broad range of developmental levels.

The diagnostic subtests measure a variety of cognitive abilities including verbal and visual working memory, immediate and delayed recall, visual recognition and matching, processing and naming speed, phonological processing, and understanding of basic number concepts. Some of these subtests can be used with children ages 2:6–17:11, while others have specific age ranges.

“DAS-II helps you find out why a child isn’t learning, and targets the specific nature of the problem, so that appropriate intervention strategies can be identified. It’s a well-rounded assessment of a child’s strengths and ability that also enables measuring change over time, in order to monitor progress.”
