Overview
The CAS2: Brief is a norm-referenced measure of cognitive ability based on the well-researched cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive). PASS abilities are evaluated using four subtests (Planned Codes, Simultaneous Matrices, Expressive Attention, and Successive Digits) which are combined to yield a Total Score. The sum of index scores can be converted into a percentile rank and composite index score with a mean of 100 and a standard deviation of 15.
Also available: See the full-length CAS2 here.
Suitable for
Children and adolescents aged 5 to 18 years
Product Description
The CAS2: Brief provides practitioners with a brief but valid and reliable tool to examine child and adolescent strengths and weaknesses in important areas of cognitive processing. The CAS2: Brief was designed to be used whenever a fast, reliable, research-based measure is needed to evaluate PASS cognitive abilities. This would include initial testing to measure overall ability and examination of variability in PASS scores to determine possible implications for intervention.
