Errorless academic compliance training is a graduated, noncoercive approach to treating oppositional behavior in children. In the present study, three teaching staff in a special education classroom were trained to conduct this intervention with three male students diagnosed with autism spectrum disorders. During baseline, staff delivered a range of academic and other classroom requests and recorded student compliance. A hierarchy of compliance probabilities was then calculated, ranging from Level 1 (requests yielding high levels of compliance) to Level 4 (those typically yielding noncompliance). At treatment initiation, teaching staff delivered high densities of Level 1 requests and provided reinforcement for compliance. Subsequent request levels were faded in over time, at a slow enough rate to ensure continued high compliance. By intervention end, all three students demonstrated substantially improved compliance to classroom requests that had commonly yielded noncompliance before intervention. Covariant improvement in on-task skills was also evident. (Contains 1 table and 3 figures.)
