Adaptive Behavior Inventory (ABI)
The ABI evaluates the functional daily living skills of school-age children and helps identify students believed to be mentally retarded or emotionally disturbed. Both the ABI
and the ABI-Short Form are completed by the classroom teacher or other professional staff, and both yield Adaptive Behavior Quotients, standard scores, and percentile ranks. The
tests were standardized on 1,296 non-disabled students and 1,076 students with mental retardation in 21 states. The demographic characteristics of the normal intelligence
standardization group approximate the eight major characteristics reported in the U.S. census.
