What is a GCA score?

The global cortical atrophy (GCA) scale, also known as the Pasquier scale, is a qualitative rating system developed to assess cerebral atrophy, especially in the context of neurodegenerative diseases.

Who created Differential Ability Scales?

The Differential Ability Scales (DAS) is one of the latest entries into the field of intelligence tests. Colin Elliot and the other developers of the DAS used the most current statistical procedures in an attempt to create a test that is psychometrically sound.

Is the DAS 2 an IQ test?

Why is DAS–II not an IQ test? The DAS–II measures a more specific and narrower domain of human cognition. Although DAS–II provides a General Conceptual Ability composite, its primary purpose is as a tool for identifying and understanding the strengths and weaknesses in individuals.

What are Differential Ability Scales (DAS)?

Differential Ability Scales (DAS) and the 2nd version can be given to children between the ages of 2 years and 6 months and 17 years and 11 months. The developmental levels vary as it relates to the children tested. One primary purpose for these tests is the classification and diagnostic efforts.

The DAS provides a range of T scores from 20 to 80. However, this range is not possible for all subtests at all ages of the test. Table-18 shows the ages at which a child could, on each subtest, obtain the lowest T score possible (20) and the highest T score possible (80).

How many achievement tests are in the Das?

The DAS also contains three achievement tests, co-normed with the cognitive battery, which allows direct ability-achievement discrepancy analysis.
