The AAMR Adaptive Behavior Scale-School: Second Edition (ABS-S:2) is a cognitive evaluation system designed for use by children with cognitive disabilities, autism, or behavior problems. It can be used to assess the functioning of children being evaluated for evidence of mental retardation, for evaluating adaptive behavior characteristics of children with autism, and for differentiating children with behavior disorders who require special education assistance from those with behavior problems who can be educated in regular class programs. The scale is divided into two parts. Part One focuses on personal independence and is designed to evaluate coping skills considered important to independence and responsibility in daily living. The skills within Part One are grouped into nine behavior domains: Independent Functioning, Physical Development, Economic Activity, Language Development, Numbers and Time, Prevocational/Vocational Activity, Self-Direction, Responsibility, and Socialization. Part Two contains content related to maladaptive behaviors in seven domains: Social Behavior, Conformity, Trustworthiness, Stereotyped and Hyperactive Behavior, Self-Abusive Behavior, Social Engagement, and Disturbing Interpersonal Behavior. The complete kit includes an examiner’s manual, 25 examination booklets, and 25 profile/summary forms, all in a sturdy storage box.
