 Das–Naglieri cognitive assessment system

The Das–Naglieri cognitive assessment system (CAS) test is an individually administered test of cognitive functioning for children and adolescents ranging from 5 through 17 years of age that was designed to assess the planning, attention, simultaneous and successive cognitive processes as described in the PASS theory of intelligence.CAS development began with an attempt to offer an alternative to the IQ test (Das, Kirby & Jarman, 1975, 1979).
