Differential Ability Scales-II (DAS-II) Scoring Assistant The DAS-II is useful for identifying strengths and weaknesses so appropriate individual education program (IEP) goals, intervention strategies, and progress monitoring can be developed; and comparing ability scores over time, even when normative scores cannot be obtained. Participants achieved significantly higher overall scores on the DAS-II and nearly half the sample achieved a higher classification label on the DAS-II. Abstract. Estimates of intelligence in young children with neurodevelopmental disorders are critical for making diagnoses, in characterizing symptoms of disorders, and in predicting future outcomes. This test provides an overall measure of cognitive abilities, referred to as a Full Scale Battery. 0000011732 00000 n Subsequent theorists have However, curve estimation revealed large mean differences that varied as a function of the child's cognitive ability level. 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. Subscales: Overall Composite Scores: General Conceptual Ability (GCA) score; Special Nonverbal Composite (SNC) score Instructions are provided in both English and Spanish for the nonverbal subtests. The following six subgroups were identified: (a) generalized, (b) high functioning, (c) normal, (d) underachievement, (e) borderline, and (f.

We conclude that interchanging MSEL and DAS-II scores 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.

Individually administered intelligence measures are commonly used in diagnostic work, but there is a continuing need for research investigating possible test bias among these measures.
