The DAS core subtests were found to be good measures of cognitive ability in children classified with ADHD and did not appear to be influenced by attention problems. It can be administered to children aged 3 years to 16 years and 11 months and provides norm-based scores in the areas of executive functioning (mental skills are used to complete tasks), attention, language, memory, learning, sensorimotor abilities, visual-spatial processing (mentally moving objects around), and social perception (forming impressions of and make inferences about others). WebThe Differential Ability Scales (2nd ed., DASII) is unique in that it goes beyond cognitive ability testing to give insight into how a child processes information. We conclude that interchanging MSEL and DAS-II scores without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution.

This test provides an overall measure of cognitive abilities, referred to as a Full Scale Battery. A cluster analysis procedure was used to identify subgroups of children who manifested specific learning disabilities in reading (SLD/R) in terms of performance on a battery of eight language and perceptual tests, finding some significant differences in measures of oral reading and reading comprehension skills. Colin Elliott and the other developers of the DAS used the most current statistical procedures in an attempt to create a test that is psychometrically sound.
