The Das-Naglieri Cognitive Assessment System (CAS) test
is an assessment test given to school children to their academic strengths and weaknesses.
Developed by Jack Naglieri, PhD
, a psychologist at George Mason University
and psychologist J.P. Das, PhD
of the University of Alberta
The test is based on the theories of Soviet neuropsychologist A.R. Luria, similarly to Alan S. Kaufman's KABC.
CAS assesses a student’s planning, attention, simultaneous and successive processes
There is criticism of this test due to its low correlation with other traditional tests.
