Functional Communication Training in Inclusive School Settings for Students With Intellectual and Developmental Disabilities: A Literature Review

Functional communication training (FCT) is a well-established, evidence-based practice used to address challenging behavior among individuals across settings, ages, and disability categories. However, the research is limited on the implementation of FCT in inclusive school settings for students with intellectual and developmental disabilities. The purpose of this review was to summarize FCT intervention studies implemented in inclusive K–12 school settings for students with intellectual and developmental disabilities. We synthesized studies to summarize study characteristics, quality, and intervention effectiveness. Our findings suggest that FCT was most often implemented as part of a multi-component intervention package and delivered by education team members. Furthermore, the quality of most studies was either acceptable or strong. The overall effect size estimate for primary dependent measures as measured by Tau-U suggested large to very large changes in student behavior. We present implications for practice specific to educational teams that support the behavioral needs of students with intellectual and developmental disabilities in inclusive settings and offer avenues for future research.
