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 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 nondisabled 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.

In addition, the mentally retarded sample is representative across several variables unique to the retarded 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.

Complete ABI Kit includes: 25 Profile and Response Sheets, 25 Short Form Response Sheets, and Examiner’s Manual, all in a sturdy storage box. (1986)
