Technical Information

Over 5,000 assessments were collected, including ratings of youth in the general population sample, clinical cases, and those included in the validity studies. The normative sample for the COSS includes ratings from 480 parents, 480 teachers, and 480 youth. The sample was stratified to represent the general U.S. population according to age, gender, and race/ ethnicity (U.S. Bureau of the Census, 2000). The normative sample is also diverse in terms of parental education level and geographic region. Separate norms are available for males and females, in 2-year age intervals (combined gender norms are also available).
