Adaptive Behavior Inventory (ABI) <show description>
The ABI evaluates the functional daily living skills of school-age children (ages 6-0 to 18-11) and helps identify students believed to be intellectually disabled 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 intellectual disabilities in 21 states. The demographic characteristics of the normal intelligence standardization group approximate the eight major characteristics reported in the U.S. census.
In addition, the intellectually disabled sample is representative across several variables unique to the disabled population in this country. Internal consistency and test-retest reliability are in the .80s and .90s at most ages. Evidence of concurrent and construct validity also is provided.
