Time: 40-60 minutes

The Cognitive Assessment System, Second Edition (CAS2) is a standardised assessment of cognitive ability based on the cognitive/neuropsychological theory PASS (planning, attention, simultaneous and successive).

• Planning - a cognitive process requiring the individual to determine, select, and use a strategy to solve a problem. The subtests require the solving of novel tasks
• Attention - a cognitive process requiring the individual to selectively attend to a particular stimulus and inhibits attending to competing stimuli
• Simultaneous - a cognitive process involving integrating separate stimuli into a single whole or group
• Successive - a cognitive process requiring the serial ordering of things

The CAS2 also yields five supplemental composite scores: Executive Function without Working Memory, Executive Function with Working Memory, Working Memory, Verbal Content, and Nonverbal Content.

The CAS2 Extended Battery has three subtests in each of the four PASS scales. The Core Battery includes two subtests from each of the four PASS scales. Each PASS scale as well as the CAS2 Full Scale yields a standard score with a mean of 100 and a standard deviation of 15.

The CAS2 can be scored online, via the CAS2 Online Scoring and Reporting System. The Online System provides an efficient and easy way to obtain CAS2 scores and corresponding narrative.

The PC, Mac, and iPad compatible System reduces scoring and reporting time and errors by:

• Converting CAS2 subtest raw scores into standard scores, percentile ranks, descriptive terms, and age equivalents
• Generating PASS and Full Scale composite scores
• Comparing CAS2 subtest and PASS scale scores to identify significant intra-individual differences
• Providing a PDF report of CAS2 performance (both Score and Interpretive Reports)
