Designed to measure cognitive processing abilities that are important for a broad range of differential diagnoses and instructional planning, the Cognitive Assessment System, Second Edition (CAS2) is a norm-referenced measure based on the well-researched cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive).
