Check In/Check Out (CICO) is a secondary tier intervention for those students who are not responsive to universal tier, school-wide positive behavioral interventions and supports. The present study extended the implementation of CICO to six students with emotional and behavioral disorders in a residential facility whose behaviors were maintained by either attention or escape. Results of a nonconcurrent multiple baseline across participants design indicate that the mean percentage of problem behavior improved for two of three students with attention-maintained behavior and two of three students with escape-maintained behavior. Future directions and limitations of the research are addressed. (Contains 5 tables and 2 figures.)
