ABA Therapy for Non-Verbal Child vs AAC: What Families Need to Know

In short: ABA therapy and AAC are not competing options; they work best together. ABA provides the structured teaching framework, while AAC gives the child a functional way to communicate. Many children use both to build language and reduce frustration.
Key takeaways
- ABA therapy and AAC are complementary, not mutually exclusive.
- AAC includes tools like picture boards, sign language, and speech-generating devices.
- ABA therapists can directly teach AAC use as part of a child's treatment plan.
- Insurance, including Medicaid, often covers both ABA and AAC evaluations.
Understanding the Basics: ABA Therapy and AAC
When your child is non-verbal or minimally verbal, finding the right support can feel overwhelming. Two terms you will hear often are ABA therapy and AAC. While they are different, they are not rivals. In fact, they often work hand in hand to help children communicate more effectively.
ABA therapy, or Applied Behavior Analysis, is a scientifically validated approach that uses positive reinforcement to teach new skills, including communication. A Board Certified Behavior Analyst (BCBA) designs individualized programs to break down skills into small, teachable steps.
AAC stands for Augmentative and Alternative Communication. It includes any method of communication besides speech, such as picture cards, sign language, or speech-generating devices. AAC gives non-verbal children a way to express needs, thoughts, and feelings.
This post will help you understand how these two approaches compare, how they can work together, and what to consider for your child.

What Is ABA Therapy for Non-Verbal Children?
How ABA Addresses Communication
ABA therapy focuses on teaching functional communication. For a non-verbal child, this might mean learning to point to a picture, use a sign, or press a button on a device. The BCBA assesses the child's current skills and creates a plan to build new ones.
Key techniques include:
- Discrete Trial Training (DTT): Breaking communication into small steps and practicing them repeatedly.
- Natural Environment Teaching (NET): Teaching communication in everyday situations, like requesting a snack during play.
- Functional Communication Training (FCT): Replacing challenging behaviors (like tantrums) with appropriate communication.
Role of the BCBA
A BCBA oversees the therapy, ensuring it is evidence-based and tailored to your child. They work with parents and therapists to track progress and adjust goals. Many BCBAs are trained to incorporate AAC into their programs.
What Is AAC and How Does It Help?
Types of AAC
AAC can be low-tech or high-tech:
- Low-tech: Picture exchange systems (like PECS), communication boards, or sign language.
- High-tech: Speech-generating devices (SGDs) or apps on tablets (like Proloquo2Go or LAMP Words for Life).
Benefits for Non-Verbal Children
AAC gives children a voice. It reduces frustration, builds independence, and can even encourage spoken language over time. Research shows that AAC does not hinder speech development; it often supports it.
A speech-language pathologist (SLP) typically evaluates a child for AAC and recommends the right system. The SLP and BCBA can then collaborate to teach the child how to use it.

ABA vs AAC: How They Compare
Different Focus, Same Goal
ABA is a teaching methodology; AAC is a communication tool. ABA provides the structure to teach a child how to use AAC effectively. Without ABA, a child might have a device but not know how to use it functionally. Without AAC, a child in ABA might struggle to generalize skills.
Common Misconceptions
- Myth: AAC will stop a child from learning to speak. Fact: Research shows AAC can support speech development.
- Myth: ABA does not support AAC. Fact: Many ABA programs actively teach AAC use.
- Myth: You have to choose one. Fact: Most children benefit from both.
How ABA and AAC Work Together
Collaboration Between Professionals
An effective approach involves the BCBA and SLP working together. The SLP selects the AAC system, and the BCBA designs the teaching plan. For example, the BCBA might set a goal for the child to request a toy using their AAC device during playtime.
Practical Example
Imagine a child who loves bubbles. In ABA therapy, the therapist might hold up bubbles and wait for the child to press a button on their device that says 'bubbles.' When the child does, they get the bubbles immediately. This reinforces the communication.
Over time, the child learns that using AAC gets them what they want, which motivates them to communicate more.

Costs, Insurance, and Getting Started
Insurance Coverage
ABA therapy is often covered by insurance, including Medicaid, under behavioral health benefits. Many states require coverage for autism treatment. AAC devices and evaluations may also be covered, but often require a separate authorization. Check with your insurance provider.

Mistakes to Avoid

Remember, every child is unique. What works for one may not work for another. The goal is to find the combination of supports that helps your child communicate and thrive.
