Behavior Assessment System for Children (BASC) Designed to assess emotional disorders, personality constructs, and behavioral problems in individuals from 2 to 21 years old, the BASC assesses behavior from three perspectives: teacher, parent, and self (starting at age 8). The system includes five rating forms and three scales. Depending on the scale, it takes 20 to 30 minutes to administer. Merenda, P.F. (1996). BASC: Behavior Assessment System for Children.
