Many children with disabilities receive the majority of their instruction in the general education classroom where many universal programs are implemented. It is therefore important to examine the impact of evidence-based universal interventions on children with disabilities. The purpose of this study was to determine whether the Incredible Years Teacher Classroom Management (IY TCM) program has benefits for children in grades Kindergarten to third grade receiving special education services. Using data from a large randomized controlled trial conducted across 105 Kindergarten to third-grade classrooms and 1,817 children, we investigated the impact of IY TCM on children receiving special education services. Findings indicated that children who receive special education supports, who were in classrooms of general education teachers trained in the IY TCM intervention, had significant improvement in concentration problems, disruptive behavior, and social competence in comparison with children receiving special education in control classrooms.
