This kit contains materials necessary to administer the Cognitive Assessment System (CAS), an assessment battery designed to evaluate cognitive processing in children 5 through 17 years of age. Derived from the Planning, Attention, Simultaneous, and Successive (PASS) theory, the four processing areas comprise the four scales that make up the CAS. The kit includes: (1) the administration and scoring manual that provides general information, specific instruction for administering and scoring the subtests, norms tables, interpretive tables, and achievement comparison tables; (2) an interpretive handbook that presents the information needed to use the tests, including a discussion of the PASS theory, explanations of the test's organization and development, as well as information on standardization and norming, reliability and validity, and interpretation; (3) a stimulus book that includes all the subtest stimuli used during administration of the tests, including nonverbal matrices, verbal-spatial relations, figure memory, and expressive attention subtests; (4) response books for paper-and-pencil responses during testing of matching numbers, planned codes, planned connections, number detection, receptive attention, and figure memory; and (5) scoring templates in a spiral bound booklet for scoring response book pages.
