Functional communication training (FCT) is an evidence-based intervention that has been widely used and implemented to reduce problem behavior and teach replacement behavior in a variety of settings. Specific procedures have been researched and documented to ensure correct implementation. Functional communication training can be broken into three steps: (a) identifying the function of the problem behavior through a functional behavior assessment (FBA); (b) selecting an appropriate replacement communicative response; and (c) building new skill acquisition through teaching and rehearsal while using reinforcements and extinction.
