Teaching to Request

Functional Communication Training (FCT) for Replacing Challenging Behavior

Functional Communication Training (FCT) teaches autistic and other neurodivergent learners to ask for wants and needs—verbally, with AAC, signs, or picture symbols—instead of using challenging behavior. By identifying why a behavior occurs (its function) and systematically teaching a safer request, BCBAs, speech-language pathologists, and educators can reduce aggression, elopement, or self-injury while boosting meaningful communication in Behavior Intervention Plans (BIPs) and IEPs.

Why use Functional Communication Training?

• Proven reduction in severe behavior. More than 30 controlled studies show FCT decreases problem behavior by 80 % or more when the replacement request is reinforced.
• Rapid language gains. Learners often begin using the taught request independently within just a few sessions, accelerating expressive-language growth.
• High generalization across settings. When teams practice FCT in multiple activities, new communication skills reliably transfer to home, school, and community environments.
