CAS 2™: Brief
Cognitive Assessment System, Second Edition: Brief
Filters
The CAS 2™: 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. Each subtest yields a scaled score based on a mean of 10 and a standard deviation of three. The sum of scaled scores can be converted a percentile rank and index score with a mean of 100 and a standard deviation of 15.
The CAS 2: Brief provides practitioners with a brief but valid and reliable tool to examine children and adolescents' strengths and weaknesses in important areas of cognitive processing. The CAS 2: 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.
