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. Subsequent theorists have 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).

HHS Vulnerability Disclosure, Help The authors concluded that interchanging MSEL and DAS-II scores in research studies 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.
