This document discusses continuous assessment systems (CAS) in education. It defines CAS as an approach that teachers can use to regularly collect, interpret, and synthesize information about students' cognitive, affective, and psychomotor development over time. The purposes of CAS include diagnosis of student understanding, informing teaching methodology, and providing formative and summative evaluation. CAS uses techniques like questioning, tests, projects, and homework assessed on a continuing basis. While CAS provides benefits like modifying instruction and developing good student-teacher relations, there are also challenges to implementing it effectively in schools.
