Description
The Differential Ability Scales-II (DAS-II; Elliot 2007) is an individually administered, comprehensive cognitive ability battery. It consists of 22 subtests for children and adolescents, aged 2 years 6 months to 17 years 11 months, making it a good choice for longitudinal studies. The DAS-II yields a General Conceptual Ability (GCA) score, diagnostic subtests, and a Special Nonverbal Composite (SNC) score. Core subtests provide a child’s GCA score, which is derived from verbal, nonverbal reasoning, and spatial cluster scores. The SNC score is derived from the nonverbal and spatial clusters and provides a valid comprehensive score for children with invalid verbal responses (Riccio et al. 1997). Diagnostic subtests do not contribute to GCA but, instead, assess aspects of memory, processing speed, and foundational abilities for early school learning (Elliott 1990).
The DAS-II is divided into early years for children 2:6–6:11, and school-age for children...
