Abstract
Test-retest reliability and parent-teacher agreement were estimated for Part Two of the AAMD Adaptive Behavior Scale—School Edition. Test-retest reliability was based on a subgroup of 20 students selected randomly from the total sample of 66; these were 7 students classified as Behavior Disordered, 7 students referred for behavior problems but not classified, and 6 students not referred or classified. Parent-teacher agreement was investigated for a subgroup of 25 students classified as Behavior Disordered. Test-retest reliability of 83 was significant, while parent-teacher agreement coefficients were nonsignificant. Such results are consistent with previous research using similar instruments. The implications are discussed and suggestions for research are presented.
