The American Academy of Child and Adolescent Psychiatry (AACAP) and American Association of Community Psychiatrists (AACP) have unified the Child and Adolescent Level of Care Utilization System (CALOCUS) and the Child and Adolescent Service Intensity Instrument (CASII) into a single instrument, the Child and Adolescent Level of Care/Service Intensity Utilization System (CALOCUS-CASII). This instrument provides a reliable framework for determining the appropriate level of care for adolescents needing mental health treatment. Using CALOCUS-CASII, providers score patients on a scale of 1-5 using a six-pronged Dimensional Rating System.
