The ABAS-3 combines all-new norms with updated item content to create the leading adaptive skills assessment. Retaining all features that made the second edition the preferred instrument for evaluating adaptive behavior, the ABAS-3 is even easier to administer and score. Comprehensive, convenient, and cost-effective, this behavior rating scale measures daily living skills—what people actually do, or can do, without assistance from others. It is particularly useful for evaluating those with developmental delays, autism spectrum disorder, intellectual disability, learning disabilities, neuropsychological disorders, and sensory or physical impairments.
Multiple Raters, Different Perspectives
The ABAS-3 includes five rating forms, each for a specific age range and rater:
  • Parent/Primary Caregiver Form (Ages 0–5)
  • Teacher/Daycare Provider Form (Ages 2–5)
  • Parent Form (Ages 5–21)
  • Teacher Form (Ages 5–21)
  • Adult Form (Ages 16–89)
Parents, family members, teachers, daycare staff, supervisors, counselors, or others who are familiar with the daily activities of the individual being evaluated can complete these forms. In addition, the Adult Form can be administered as a self-report. The items may be read aloud to raters who have low sight or reading skills.
Skills and Domains Consistent with AAIDD, DSM-5, IDEA, and RTI Guidelines
The ABAS-3 covers three broad adaptive domains: Conceptual, Social, and Practical. Within these domains, it assesses 11 adaptive skill areas (each form assesses 9 or 10 skill areas based on age range). Items focus on practical, everyday activities required to function, meet environmental demands, care for oneself, and interact with others effectively and independently. On a four-point response scale, raters indicate whether the individual can perform each activity, and if so, how frequently they perform it when needed.
The ABAS-3 is aligned with the AAIDD, DSM-5, and IDEA specifications, and works well within an RTI context. It generates norm-referenced scaled scores and test-age equivalents for the 11 skill areas. It also provides standard scores, confidence intervals, and percentile ranks for the three broad adaptive domains and the summary score—the General Adaptive Composite. In addition, all scores can be categorized descriptively (Extremely Low, Low, Below Average, Average, Above Average, High).
The ABAS-3’s paper-and-pencil forms have been redesigned and are even easier to use than preceding editions of the ABAS. Scoring is quick and you can use the results to create and achieve therapeutic goals with the ABAS-3 Intervention Planner™. The Planner allows users to create a customized therapy plan based on adaptive skill area deficits identified by the ABAS-3.
Complete ABAS-3 kit includes: 5 Parent/Primary Caregiver Forms; 5 Teacher/Daycare Provider Forms; 5 Parent Forms; 5 Teacher Forms; 5 Adult Forms; Manual; Intervention Planner, all in a sturdy storage box.
