Technical Information

ABAS-II assesses an individual in all 10 specific adaptive skills areas specified in the DSM-IV:

  • Communication

  • Community Use

  • Functional Academics

  • Home Living

  • Health and Safety

  • Leisure

  • Self-Care

  • Self-Direction

  • Social

  • Work

Scores for each area allow you to evaluate areas of functioning, determine strengths and weaknesses, and specify training goals.

Also use ABAS-II to evaluate individuals with learning difficulties, ADD/ADHD, or other impairments related to motor, speech and language, hearing, and neuropsychological disorders to determine how well the individual is responding to daily demands from the environment.

New Downward Extension - birth to 5 years

The ABAS-II now has a downward extension of norms that will allow you to assess the strengths and weaknesses in the areas of adaptive skill specified in the DSM-IV as well as in the three general areas of adaptive behaviour.

The downward extension allows you to assess young children suspected of having developmental delays.

Broad Usage

ABAS-II is an excellent tool to use with a Wechsler Scale for determining intellectual disability. Use it for evaluating levels of adaptive skill and specifying treatment goals for individuals with learning disabilities or other types of learning, behavioural, medical, and psychological problems.

ABAS–II Intervention Planner and Scoring Assistant

Enhanced software makes evaluating infants through to adolescents even easier

With the ABAS-II Intervention Planner and Scoring Assistant you can now identify the appropriate interventions and monitor progress.

The software will help you develop:

An Interpretive Report narrative based on all scores, strengths and weaknesses analysis, composite score discrepancy analysis, and overall summary of adaptive behaviour for all ages

  • A summary comparison statement of overall intellectual and adaptive functioning if WPPSI–III or WISC–IV Full Scale IQ is entered for ages 2 and a half to 17 years

  • Item-level interventions for those items chosen by the clinician for ages 0-17

  • A Progress Monitoring Report comparing raw and scaled scores across up to 4 assessments for ages 0-17

  • A Respondent Report (for parent/primary caregiver or teacher/day-care provider) providing an easy to understand description and graph of the child’s adaptive functioning based on his/her scores for ages 0-17 

NOTE: This software is not Mac OS compatible.
