Secondary level or Tier 2 interventions such as the Check-in Check-out (CICO) intervention effectively reduce problem behaviors of students who are non-responsive to school-wide interventions. However, some students will not be successful with Tier 2 interventions. This study investigated the effects of adding individualized function-based support for four students with disabilities who were not successful in general education settings while receiving only a secondary level intervention. Results indicated that the combination of secondary and individualized function-based interventions effectively decreased problem behavior for all participants. Teachers and students rated the interventions as acceptable and effective. Research and practice implications are discussed.
