What age range gets the adult form of the ABAS?

• A. 16-89
• B. 18-90
• C. 21-99
• D. 16-89

Answer: (D)

The main idea is that the adult form of the ABAS is designed for older teens and adults, covering a broad lifespan. It uses items and normative data that apply from mid-teens up through late adulthood, specifically 16 years old up to 89 years old. That wide range makes it the appropriate form for anyone from around 16 to 89, which is why this option is the best match. Ranges that start at 18 or 21 miss the lower end, and a upper limit beyond 89 isn’t aligned with the standard ABAS adult form norms, so they don’t fit as well.
