What is the overall measure of cognitive abilities referred to in the DAS-II assessment?

The Differential Ability Scales – Second Edition (DAS-II; Elliott, 2007) is an individually administered, norm-referenced instrument that assesses the cognitive abilities of children and adolescents ages 2 years, 6 months through 17 years, 11 months.

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 does it mean if a person’s IQ is 115?

85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.

What is Woodcock Johnson III tests of cognitive abilities?

These three cognitive tests measure three abilities; Comprehension-Knowledge (Gc), Fluid Reasoning (Gf), and Processing Speed (Gs), which best represents an individual’s verbal ability, thinking ability, and efficiency in performing cognitive tasks.

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.

What are the different types of scores in the DAS-II?

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.
