Useful for Diagnosing and Classifying Developmental, Learning, and Behavioral Disabilities and Disorders
Identifying your clients' strengths and weaknesses; and documenting and monitoring progress over time, the ABAS-3 provides a comprehensive norm-referenced assessment of adaptive skills in individuals ages birth–89 years.
Features and benefits
- Retains all the essential features that made the second edition the preferred instrument but is even easier to administer and score.
- 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.
Available in Spanish
Several ABAS-3 forms have been translated into U.S. Spanish: the Adult Forms, the School: Parent Forms, the School: Teacher Forms, the Infant and Preschool: Parent/Primary Caregiver Forms, and the Infant and Preschool: Teacher/Daycare Provider Forms. These products use English norms only.

FAQs
What is the technical information for the ABAS™-3?
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.

Scoring and reporting
- Professional users have three options for obtaining ABAS-3 scores from a paper form: scoring by hand, using the Scoring Assistant software, and using the WPS Online Evaluation System.
- ABAS-3 scoring procedures allow users to sum item ratings into adaptive skill area raw scores.
- These are converted to adaptive skill area scaled scores, adaptive domain standard scores, and the General Adaptive Composite (GAC) score.
- Together, these scores form the basis of an individual’s comparison with same age peers from the standardization sample.
Technical information
- Norm-referenced scaled scores are provided for the 11 skill areas; for the three adaptive domains and the GAC, norm-referenced standard scores, confidence intervals for standard scores, and percentile ranks are provided. In addition, all scores can be categorized descriptively.
- Norms are based on a large sample representative of the U.S. population.
