Present Use
CAS assesses a student’s planning, attention, simultaneous and successive processes (PASS). It is used among educational-psychologist because it gives good guidelines to educational interventions.Criticisms
In independent factor analytic studies conducted by Tim Keith and John Kranzler after the CAS was first published the 4 factor PASS model could not be reliably replicated. Instead a 3 factor model (PA)SS model, combining the planning and attention factors together was found to fit the data best. Although Naglieri took issue with the research in submitting several rebuttals, additional studies have replicated the Keith and Kranzler results indicating that there remain significant questions about the construct validity of the CAS. Other researchers question why a full scale score (which correlates rather high with other global IQ scores) is included since the test is marketed as an alternative to traditional IQ tests.See also
