Differential Ability Scales - Test Structure

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.

Famous quotes containing the words test and/or structure:

    Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
    [sic] and to investigate other aspects of nature.
    Ian Hacking (b. 1936)

    A special feature of the structure of our book is the monstrous but perfectly organic part that eavesdropping plays in it.
    Vladimir Nabokov (1899–1977)
