There are five ABAS-3 rating forms, each for a specific age range and respondent. On a 4-point response scale, raters indicate whether, and how frequently, the individual performs each activity. In addition, the Adult Form can function as a self-rating.

  • 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)

These forms can be completed by parents, family members, teachers, day-care staff, supervisors, counsellors, or others who are familiar with the daily activities of the individual being evaluated.

The ABAS-3 can be administered and scored by hand, administered by hand and scored via software, or fully administered online.

The WPS Online Evaluation System makes administering and scoring the ABAS-3 faster and more accurate, offering improved clinical efficiency. Online testing allows clinicians to administer all forms remotely or in-person, check the status of an administration at any time, score and report automatically, create customised intervention plans and quickly compare two raters’ scores.
