What It Actually Means

Every behavior communicates something, whether or not it's the message a child intends. Functional communication training identifies what a behavior is actually accomplishing (getting attention, escaping a task, getting an item, expressing discomfort) and teaches a clear, appropriate way to ask for that same thing directly, so the behavior has less reason to happen.

How to Start at Home

  • Watch for what a behavior seems to get your child. Not just what the behavior looks like, attention, escape, an item, or a sensory need are the most common.
  • Teach a specific, simple replacement for that exact function. A word, sign, picture card, or device button, whatever fits your child's communication level.
  • Respond to the replacement quickly and reliably. Especially early on, so it's clearly worth using.
  • Use the same replacement consistently across every caregiver and setting. So it generalizes rather than only working with one person.
The goal isn't to stop the behavior. It's to make the behavior unnecessary.

What Not to Do

  • Don't teach a general “communication skill” disconnected from a specific need, functional communication works because it's tied directly to what the child actually wants.
  • Don't require increasingly complex requests before responding, start with whatever is achievable now, and build complexity later.
  • Don't ignore a correctly used replacement, even occasionally, inconsistent responses slow the whole process down.
Try This

If a behavior seems to be about escaping a hard task, teach and immediately honor a simple “break” request (a word, sign, or card) the moment it's used, even for just a short break, so it clearly works as well as, or better than, the old behavior.

As the Skill Builds

  • Gradually add small delays or expectations before honoring the request, once the basic skill is solid, a short wait, a small task first.
  • Expand the replacement to more settings and people, one at a time.
  • Keep an eye on which function is still hardest to communicate, and focus new teaching there.

Working With Your Child's Team

  • If you're working with a BCBA or speech therapist, ask specifically what function they believe is behind a target behavior, it shapes exactly what to teach.
  • Share what's working (or not) at home; functional communication plans usually need adjusting as a child's skills grow.
  • Be patient, replacing a well-established behavior with a new communication skill takes consistent practice over weeks, not days.
This guide is educational and general in nature. It isn't a substitute for individualized guidance from your child's BCBA, therapist, pediatrician, or other provider, if you're working with one, they know your child's specific triggers and history best.
