Clinical and educational assessment of children requires reliable and valid measures of their behavioral, cognitive, and emotional functioning. The inadequacy of traditional psychiatric categories has long been recognized, and the importance of accurate child adjustment information for educational placement has been appreciated increasingly. This study evaluated the external validity of a new, 12 profile type classification system for the Personality Inventory for Children (PIC) and used cognitive functioning and special education placement data as external criteria. Children who obtained the 12 PIC profile types differed significantly in their performance on several individually administered intellectual and academic tests and their placement in regular vs. special education classrooms. Implications of these findings for use of this profile typology as a screening tool in educational settings are discussed.
