Test Structure

The DAS-II consists of 20 cognitive subtests which include 17 subtests from the original DAS.

The subtests are grouped into the Early Years and School-Age cognitive batteries with subtests that are common to both batteries and those that are unique to each battery. These batteries provide the General Conceptual Ability score (GCA), which is a composite score focusing on reasoning and conceptual abilities.
