Teaching Functional Communication Skills — Replacing Frustration with Connection
For many children with autism or developmental delays, communication isn’t as simple as speaking a few words. When they can’t clearly express their needs, it often results in frustration — and sometimes, challenging behaviors. That’s where Functional Communication Training (FCT) comes in.
FCT is an ABA-based approach that teaches children appropriate ways to communicate their needs, whether that’s requesting a break, asking for help, or saying no. It helps replace negative behaviors (like tantrums or aggression) with meaningful, effective communication.
What Is Functional Communication?
“Functional” means practical — communication that serves a clear purpose. Rather than simply teaching a child to label objects (“apple,” “ball”), FCT focuses on teaching how to make requests, refuse unwanted things, or gain attention in positive ways.
The form of communication can vary depending on the child’s ability:
Spoken words
Sign language
Picture Exchange Communication System (PECS)
Speech-generating devices
Gestures or pointing
Why Is FCT So Powerful?
Challenging behaviors are often a child’s way of saying, “I need something,” or “I don’t like this.” When we teach them an easier, more appropriate way to get their needs met, those behaviors often fade.
For example:
A child who hits when they want a toy can learn to point or hand over a picture card.
A child who runs away during transitions can learn to request a break.
A child who cries when frustrated can be taught to say “help.”
Step-by-Step: How FCT Works
Identify the Function of the Behavior
Is the child seeking attention? Avoiding a task? Wanting an item? This helps determine what replacement behavior to teach.Choose a Communication Method
Match the method to the child’s developmental level. For nonverbal children, this might be a simple picture exchange or gesture.Teach in the Moment
When the child begins to show signs of frustration, prompt the new communication skill immediately. For example, if a child starts to whine for a snack, gently guide them to say “snack” or hand over a picture.Reinforce Immediately
When the child uses the new skill, give them what they asked for right away. This builds a strong association between the behavior and the result.Practice and Generalize
Use the new communication skill in different settings (home, school, playground) to make it stick.
Real-Life Example
Meet Noah, age 4. Every time he wanted his iPad, he’d scream and throw objects. His therapist discovered the function was access to a preferred item. They taught him to hand over a picture of the iPad instead. Within weeks, his problem behavior decreased, and he began independently requesting his device calmly.
Tips for Parents
Keep communication tools (like picture cards) accessible.
Be consistent. Reinforce the correct communication every time.
Don’t give in to challenging behaviors. Wait for the appropriate request.
Celebrate progress — even small steps matter.
Final Thoughts
Functional Communication Training isn’t just about reducing behaviors — it’s about empowering your child to connect with the world in a more positive, confident way. You’ll start to see fewer meltdowns and more moments of understanding.
