Replacement Behaviors in ABA: Examples Parents Can Use

When a child hits, screams, throws things or runs off, the first instinct is to make the behavior stop. ABA asks a different question: what should the child do instead? The answer is a replacement behavior, a safer and more useful way for the child to get the same need met. This guide explains what replacement behaviors are, how they are chosen, examples for common challenges and how families in North Carolina can practice them at home.

What is a replacement behavior?

A replacement behavior is a skill taught to take the place of a challenging behavior. The key is that it must serve the same function. If a child screams to get a break from a hard task, the replacement behavior should also get a break, for example asking "break please" or handing over a break card.

Every behavior serves a purpose. ABA groups those purposes into the four functions of behavior: escape, attention, access to items or activities, and automatic or sensory reinforcement.

Key takeaway: If the replacement behavior does not meet the same need as the challenging behavior, the challenging behavior will usually come back.

Why stopping a behavior is not enough

If a behavior is simply blocked or ignored, the child still has the same need, and no new way to meet it. Often the child tries harder or finds another challenging behavior. Teaching a replacement gives the child a better option, which makes change last longer and feel kinder for everyone.

How ABA teams choose a replacement behavior

Step 1: Find the function

A BCBA studies when and why the behavior happens, often through a functional behavior assessment and ABC data.

Step 2: Pick a skill that matches the function

The new skill must get the same result as the challenging behavior, such as a break, attention or a toy.

Step 3: Make it easier than the challenging behavior

The replacement should take less effort and work faster. If saying a full sentence is hard, a single word, sign or picture card may be the better starting point.

Step 4: Reinforce it every time at first

Early on, the replacement behavior should work every time it is used. Later, adults can slowly teach waiting and accepting "not right now."

Info: A good replacement behavior is fast, easy and works better than the problem behavior.

Replacement behavior examples by function

Escape: getting away from a task or situation

• Challenging behavior: throwing worksheets during homework.
• Replacement behavior: asking for a break, using a break card or asking for help.
• Support: shorter tasks, easier first steps and planned breaks.

Attention: getting interaction from others

• Challenging behavior: yelling while a parent is on the phone.
• Replacement behavior: tapping the parent's arm, saying "excuse me" or showing a "talk to me" card.
• Support: giving attention often when the child is calm.

Access: getting a toy, food or activity

• Challenging behavior: grabbing a tablet from a sibling.
• Replacement behavior: asking "my turn," pointing to a picture or using a device to request.
• Support: visual timers for turn taking and clear first-then routines.

Sensory: getting a feeling or input

• Challenging behavior: chewing on shirt collars until they tear.
• Replacement behavior: using a chewy necklace or crunchy snack.
• Support: regular sensory breaks during the day.

Strategies used to teach replacement behaviors

• Functional communication training: teaching a word, sign or picture that requests the same outcome. Read more about functional communication training.
• Differential reinforcement: giving reinforcement for the replacement behavior and less for the challenging behavior. See our guide to differential reinforcement.
• Prompting and fading: helping the child use the new skill, then reducing that help over time.
• Antecedent strategies: changing the situation so the challenging behavior is less likely in the first place.
• Practice when calm: rehearsing the new skill during easy moments so it is ready during hard ones.

How parents can practice replacement behaviors at home

1. Pick one behavior. Focus on the challenge that matters most for safety or daily life.
2. Guess the need. Ask, "What does my child get when this happens?"
3. Choose a simple skill. A word, sign, gesture or picture that gets the same thing.
4. Practice when things are calm. Model it, help your child try it and reward it right away.
5. Respond fast. When your child uses the new skill, honor it quickly so it is worth using.
6. Stay consistent. Make sure everyone at home responds the same way.
7. Share what you see. Tell the ABA team what works and what does not.

Success tip: Say exactly what you liked. "Great job asking for a break" teaches more than "good job."

Common mistakes to avoid

• Choosing a replacement that does not match the function.
• Making the new skill harder than the challenging behavior.
• Ignoring the replacement behavior when it is used.
• Expecting the new skill to work in stressful moments before it has been practiced in calm ones.
• Giving the item or break only after the challenging behavior, which teaches the old pattern again.

Frequently asked questions

What is an example of a replacement behavior?

If a child hits to escape a task, a replacement behavior might be asking for a break or using a break card. Both get the same result in a safer way.

How long does it take for a replacement behavior to work?

It depends on the child and how consistently the skill is practiced. Many families see early changes within a few weeks when everyone responds the same way.

Is a replacement behavior the same as functional communication training?

Functional communication training is one way to teach a replacement behavior. Replacement behaviors can also include coping, waiting, sensory or play skills.
