The Cognitive assessment system (CAS) is a standardized test that measures children’s mental abilities as defined by the Planning, Attention, Simultaneous and Successive (PASS) theory of cognitive function individual among 5 to 11-17 years old students .Cognitive assessment system began with an attempt to offer an alternative to the IQ test .and used for understanding cognitive development of typical and atypical children, as well as cognitive impairment in adults. Methods for using the PASS scores to identify the cognitive strengths and weaknesses, as well as related academic weaknesses, are also given. The CAS Standard Battery has four PASS scales such as Attention , Simultaneous , planning and Successive subtests. Each of the four PASS scales …show more content…
Expressive attention (a variation of the Stroop test) has two forms, one for children 7 years and younger, and the other 8 & over. The receptive attention subtest contains two separate tasks; in the first task, targets are letters that are physically the same .For the second task, targets are letters that have the same name . Simultaneous Scale includes nonverbal matrices, verbal spatial relations, and figure memory. In this subtest, the students have been presented with six drawings, arranged in a specific spatial manner, and a printed question (e.g., show me the triangle to the left of the circle). The participants have been asked to choose one of the six drawings that best answers the question. IN Figure memory, a combination of Figure-Copying and Memory for Designs, the child is presented a two- or three-dimensional geometric figure for 5 seconds and then presented immediately with a response page, on which the original geometric figure is embedded in a larger, more complex geometric pattern. The child is asked to identify the original design. At the end , The scores of CAS should compare with the academic scores of students in both group
