The Direct Answer
ABA therapy is one of the most effective treatments for nonverbal children with autism. It uses specialized approaches — including Verbal Behavior techniques, Functional Communication Training, and AAC (Augmentative and Alternative Communication) support — to build communication skills in any form: spoken words, sign language, picture exchange, or speech-generating devices.
When parents hear "ABA therapy," many picture a child sitting at a table doing repetitive drills. For nonverbal children, that image couldn't be further from current best practice. Today's ABA programs for nonverbal children are built around one central question: what does this child need to communicate, and what's the best way to get there?
The answer is different for every child — and a good BCBA will build a program that starts where your child is, not where a textbook assumes they should be.
What "Nonverbal" Actually Means
The term "nonverbal" is often used loosely to mean a child isn't using spoken words. In practice, there's a wide spectrum. Some children are completely silent. Others have a handful of sounds or word approximations. Some children are "minimally verbal" — meaning they have fewer than 20–30 functional words — and are sometimes grouped with nonverbal children in research.
What all these children share is that spoken language isn't yet a reliable, functional way for them to communicate their needs, feelings, and ideas. ABA therapy addresses that directly, regardless of where on the spectrum a child falls.
Verbal Behavior: The ABA Framework Built for Language
Within the broader field of ABA, there is a specialized framework called Verbal Behavior (VB), developed from the work of behaviorist B.F. Skinner. Verbal Behavior treats language as a behavior — something that can be taught, shaped, and reinforced systematically, just like any other skill.
Rather than focusing only on whether a child says words, VB breaks communication down into functional categories:
- Manding: Requesting things the child wants. ("Juice," "more," "help") — This is usually taught first because it's immediately motivating for the child.
- Tacting: Labeling objects, actions, or events in the environment. ("Dog," "running," "hot")
- Intraverbals: Conversational responses and fill-ins. ("What do you do when you're hungry?" "Eat.")
- Echoics: Repeating what someone else says — a foundational skill that some nonverbal children need to build before other language can develop.
By teaching these categories systematically, Verbal Behavior ABA helps nonverbal children build a functional communication foundation — whether that ends up being spoken words or another form.
AAC and ABA: Working Together
Not every nonverbal child will develop functional speech — and for many, Augmentative and Alternative Communication (AAC) is the bridge to meaningful communication. AAC includes:
- PECS (Picture Exchange Communication System) — using picture cards to request and communicate
- Sign language or manual signing
- Speech-generating devices (SGDs) like iPads with communication apps (Proloquo2Go, TouchChat, LAMP)
- High-tech voice output communication aids (VOCAs)
A common concern parents have is: Will using AAC prevent my child from developing speech? The research consistently says no — AAC does not reduce a child's motivation to talk. In many cases, giving a child a reliable way to communicate actually reduces frustration, decreases challenging behaviors, and creates a foundation for speech development.
A reassurance for parents: Using AAC is not giving up on speech. Multiple studies have shown that children who use AAC often develop more spoken language over time — not less. The goal is always to give your child the most effective communication tool available right now, while continuing to work toward expanded spoken language.
Functional Communication Training (FCT)
One of the most important tools ABA uses with nonverbal children is Functional Communication Training (FCT). FCT is used when a child is engaging in challenging behaviors — hitting, biting, screaming, throwing — because they don't have a reliable way to communicate what they need.
FCT works by identifying the function of the challenging behavior (Is the child trying to escape something? Get something? Get attention?) and then teaching a communication replacement that serves the same purpose. For example:
- A child who bites when they want a break is taught to hand a "break" card or press a button on their device
- A child who screams to get food is taught to touch a picture of the food or point to a symbol
- A child who hits to get adult attention is taught to tap an adult's arm or use a "help" symbol
FCT is often one of the first goals in an ABA program for nonverbal children because it addresses both safety and communication simultaneously. When challenging behaviors decrease, children also become more available for learning.

Get Matched NowWhat Goals Look Like for a Nonverbal Child in ABA
ABA goals for nonverbal children are individualized — but here are some common early targets:
- Requesting preferred items using a picture, sign, or device (manding)
- Tolerating communication attempts without becoming distressed
- Imitating sounds or mouth movements (building toward speech)
- Responding to their name and simple instructions
- Using "help," "more," "stop," and "all done" in daily routines
- Matching pictures to objects
- Tolerating AAC device prompting during play
Progress with nonverbal children can be slower to appear in spoken output, but that doesn't mean progress isn't happening. Receptive language (understanding), engagement, reduced behaviors, and expanded AAC use are all real and meaningful forms of progress — even before a child says their first word.
What to Look for in an ABA Provider for a Nonverbal Child
Not all ABA programs have equal experience with nonverbal children. When evaluating providers, ask specifically:
- Do you have experience working with nonverbal or minimally verbal children?
- Does your team use AAC systems? Which ones?
- How do you incorporate speech therapy into your ABA program?
- Is your BCBA trained in Verbal Behavior approaches?
- What does a typical session look like for a nonverbal 3-year-old?
Speech therapy + ABA together
Many children benefit from both ABA and speech-language therapy (SLP). ABA focuses on the behavioral and motivational side of communication; SLP works on the motor, articulation, and language development side. When BCBAs and SLPs coordinate their goals and strategies, children typically make faster progress than when these services are siloed.
Getting Started in NY, NJ, or NC
