Features and benefits

- Particularly useful for evaluating those with developmental delays, autism spectrum disorder, intellectual disability, learning disabilities, neuropsychological disorders, and sensory or physical impairments.
- Integrates assessment, intervention planning, and progress monitoring.
- Developed with American Association on Intellectual and Developmental Disabilities (AAIDD), DSM-5, and IDEA standards in mind.
Test structure
- Within three major adaptive domains (Conceptual, Social, and Practical), the ABAS-3 assesses 11 skill areas: communication, community use, functional academics, health and safety, home or school living, leisure, motor, self-care, self-direction, social, and work.
- Items focus on practical, everyday activities required to function, meet environmental demands, care for oneself, and interact with others effectively and independently. On a 4-point response scale, raters indicate whether, and how frequently, the individual performs each activity.
- A General Adaptive Composite (GAC) is produced.
