Is TABS a norm-referenced scale?
Yes. TABS was standardized and normed in 33 states on nearly 1000 children including children with typical and atypical development from diverse socioeconomic and ethnic backgrounds. The norming and field validation research encompassed various diagnostic disability groups, including autism spectrum disorders, attention-deficit/hyperactivity disorders, general developmental delays, mental retardation, cerebral palsy, seizure disorders, and early drug and alcohol exposure.
