Guide for use:

The Children's Global Assessment Scale (CGAS) was developed to provide a measure of severity of disturbance in children and adolescents. It is designed to reflect the lowest level of functioning for a child or an adolescent during a specified period.

The measure provides a single global rating only, on a scale of 1 to 100. Clinicians assign a score, with 1 representing the most functionally impaired child, and 100 the healthiest child.

Scale ranges:

100-91 Superior functioning in all areas
90-81 Good functioning in all areas
80-71 No more than slight impairments in functioning
70-61 Some difficulty in a single area but generally functioning pretty well
60-51 Variable functioning with sporadic difficulties or symptoms in several but not all social areas
50-41 Moderate interference in functioning in most social areas or severe impairment of functioning in one area
40-31 Major impairment of functioning in several areas and unable to function in one of these areas
30-21 Unable to function in almost all areas
20-11 Needs considerable supervision
10-1 Needs constant supervision
