This paper presents a review of literature of cognitive Assessment system (CAS) developed by J. P. Das and Jack A. Naglieri in1997 following their PASS theory (Planning, Attention, Successive & Simultaneous) based on Luria�s model of neuropsychological processing. CAS is a reliable measure of cognitive functioning which has proved its validity across cultures. CAS is acquiring professional status in assessment of multiple as well as specific neuropsychological processing over the past 27 years. The battery has also resulted in remedial tests such as PREP (PASS Remedial Enhancement Program). This paper traces the CAS through important research papers published in various international journals and books between 1983 and 2012
