Your child threw the bowl this morning. Not because they were angry at you. Because they were trying to show you something, and the bowl was the only signal available in that moment.

That is not a behavior problem. That is a communication gap. And it is one parents can learn to close.

What Is the Silence to Signals™ Communication Framework?

The Silence to Signals™ Communication Framework is a structured communication interpretation system for parents of non-speaking and minimally speaking autistic children, built around the six-stage SIGNAL Path. It is designed for families of children ages 2 through 12. It teaches parents to identify, interpret, and respond to the full range of signals their child is already sending, including pre-symbolic, non-verbal, behavioral, and emerging AAC signals, with consistency and confidence.

It was built by Dr. Catherine C. Acotto, PhD, CCC-SLP. It works alongside the approaches a family may already be using: Floortime, SCERTS, TEACCH, AAC, and ABA. Those approaches ask parents to decide what their child's behavior means before they respond. This framework teaches them how.

Who Built the Framework, and What Is the Evidence Behind It?

Dr. Acotto holds a PhD in Curriculum and Instruction from Arizona State University (2014) and a master's degree in Communication Sciences and Disorders with an emphasis in Autism, and she holds the CCC-SLP credential from the American Speech-Language-Hearing Association. She has 26 years of practice and more than 50,000 clinical hours, all with non-speaking and minimally speaking autistic children. She still works in a preschool autism program, so she isn't teaching from memory. She's teaching from last Tuesday.

Her 2014 ASU dissertation followed one teenage girl with autism whose aggression and self-injury filled two hours of a five-hour school day. Teaching her to ask had already been tried, and it changed very little, because it fell apart the moment the answer was no. What changed things was what Dr. Acotto did in that moment. That cut the duration of those episodes by 64% in a big box store, 74% in a grocery store, and 81% in her classroom, sustained at six-month follow-up. One girl, one study, published under her own name: proof of concept for what changes when communication access increases.

What Is Signal Literacy, and Why Is It the Goal?

Signal Literacy™ is a caregiver's developed ability to accurately identify, interpret, and respond to a child's full signal system, including pre-symbolic, non-verbal, and behavioral signals, with consistency and confidence.

Most parents start somewhere else. They start in what the framework calls Signal Chaos™: the experience of a caregiver who has not yet developed Signal Literacy, characterized by confusion, reactivity, exhaustion, and the feeling that their child's communication is random or intentionally defiant. Signal Chaos is not a parenting failure. It is the predictable result of raising a child who communicates fluently in a system no one translated for you.

The framework moves a parent from Signal Chaos to Signal Literacy through six sequential stages. Each stage builds on the one before it. Together they form a complete interpretive system that a parent can run at home, across environments and with the people in the child's life.

What Are the Six Stages of the SIGNAL Path?

S: See the Child (Recognizing the Signals Already Present)

The first stage addresses observation: watching a child without immediately interpreting or reacting to what you see.

At Stage 1, a parent learns to stop filtering their child's behavior through the lens of intent ("why are they doing this to me") and start reading it as information. Gestures, movements, sounds, repeated behaviors, and withdrawal are all signals. Most parents are already catching signals they do not have names for. Stage 1 gives them the names and a way to log them systematically in the Signal Inventory™, a structured, parent-completed mapping tool that catalogs every signal a child is currently using. This stage also introduces the Signal Classification Table, which sorts every signal a child produces into one of three types: communicative, regulatory, or mixed. The type tells the parent what kind of response is needed.

I: Interpret the Behavior (What the Signal Means)

The second stage addresses interpretation: working out what a signal is for at the moment it appears.

This is where the Eight Signal Functions™ become the core tool. The Eight Signal Functions are the specific purposes a child's signals serve: Request, Protest, Comment, Greet, Seek, Share, Regulate, and Refuse. The signals that look like behavior problems serve these same purposes. Once a parent can read the purpose, they can respond to what the child actually needs rather than to the surface behavior.

Stage 2 also teaches the nervous system states that decide whether communication is accessible at all, and the Regulation Decision Algorithm: the decision sequence that gives the specific response for each nervous system state, in the order it should be applied. It starts with one question before every interaction: what state is my child's nervous system in right now? Communication flows when the body feels safe.

G: Get in Sync (Building the Relational and Regulatory Foundation)

The third stage addresses co-regulation: how a parent's own regulated nervous system becomes one of the most important regulation supports their child has.

A child's nervous system reads the adult's, often before anything the adult says has registered. Stage 3 teaches parents the Synchrony Protocol Loop: observe the child's rhythm, join it, narrate, expand by adding a symbol, then hold a Signal Pause™ and wait. The Signal Pause, that deliberate moment of quiet, is where the child's next signal has room to arrive.

N: Normalize Symbols (Introducing AAC Without Fear)

The fourth stage addresses augmentative and alternative communication: how and when to introduce AAC tools, and how to do it in a way that supports, rather than replaces, the communication a child has already built.

Research does not support the concern that AAC prevents speech. A systematic review found that AAC intervention does not impede speech production, and most of the studies it examined reported some gains in speech (Schlosser and Wendt, 2008, American Journal of Speech-Language Pathology). Stage 4 gives parents the framework to introduce symbol-based communication (picture systems, speech-generating devices, sign) without anxiety and without undermining the child's existing signal system. Parents learn to model symbols without pressure, so access comes first and no demand is attached.

A: Anticipate Breakdowns (Reading the Signal Sequence Before the Meltdown)

The fifth stage addresses one of the most practically urgent skills a parent can develop: reading the escalation sequence before it reaches crisis.

A meltdown rarely comes from nowhere. It is usually the last signal in a sequence, and the earlier signals in that sequence are readable. Stage 5 teaches parents to map their child's own Signal Amplification™ sequence. Signal Amplification is the natural increase in signal intensity that occurs when a child's communication attempts go unrecognized or unmet. It is not a behavior problem. It is a volume increase on an unheard message. Parents learn to catch the first quiet signs of overload, including the moment a child's Signal Window™ starts to narrow, and to respond while a small change is still enough.

Stage 5 also teaches the SIGNAL Repair Protocol™ for the moments when escalation happens anyway, and shows parents how to redesign the routines and environments where breakdowns cluster.

L: Layer Communication (Expanding the System Across Every Context)

The sixth stage addresses generalization: taking what a parent has learned and applying it reliably across people, places, and hard days.

A communication system that works only when the child is regulated and the environment is controlled is not yet a communication system. It is a good day. Stage 6 teaches parents to expand the child's signal system, generalize it across settings and caregivers, and sustain it over time. This is the stage where reading your child's system with real confidence becomes the daily operating state rather than an occasional achievement.

How Is Signal Fluency Measured?

Signal Fluency™ is how fluently a parent is already reading their child's communication, measured by the 24-question Signal Fluency Assessment™ and scored from 24 to 96 in four types: Signal Overwhelm (24–42), Signal Awareness (43–60), Signal Emerging (61–78), and Signal Fluency (79–96).

The Signal Fluency Assessment™ was built by Dr. Acotto. It shows a parent where they currently stand, which SIGNAL category is already their strongest, and where the biggest growth is waiting. It takes four minutes. It is the recommended starting point before beginning the SIGNAL Path, because it tells a parent where to focus first.

What Does the Framework Not Ask You to Do?

It does not ask you to change your child.

Floortime, SCERTS, TEACCH, AAC, and ABA each ask the adults around a child to decide what the child's behavior means before they respond. The Silence to Signals™ Communication Framework is the part that teaches how, and it works alongside every one of them.

The framework places the interpretive work on the adult. When the adult learns to read the signal system the child already has, communication begins before the child is asked to produce anything new.

That is not a philosophical preference. It is how communication works between any two people: someone sends, and someone has to learn to receive.

Where Should a Parent Start?

If you have not yet taken the Signal Fluency Assessment, start there. It shows you what you are already reading, where you are strongest, and where to focus first as you move through the SIGNAL Path.

If you downloaded the Transition Signal Guide and want to understand the full framework behind it, this post is the overview. The guide works on one breakdown context, transitions, with one tool. Stage 5, Anticipate Breakdowns, applies the same lens to every breakdown context in your child's day, and the six-stage SIGNAL Path is the system it belongs to.

Frequently Asked Questions About the Silence to Signals™ Communication Framework

What does the Silence to Signals™ Communication Framework teach parents to do? It teaches parents of non-speaking and minimally speaking autistic children to identify, interpret, and respond to the communication their child is already sending through gesture, movement, sound, behavior, and AAC, using a six-stage sequence called the SIGNAL Path.

Who is the framework designed for? It is designed for parents and caregivers of non-speaking and minimally speaking autistic children, ages 2 through 12. No clinical background is required. The framework is built to run at home.

How is the framework different from ABA, Floortime, or SCERTS? Those approaches ask parents to decide what a child's behavior means before they respond. The Silence to Signals™ Communication Framework teaches them how to make that determination. It is not a replacement for any existing approach. It is the interpretive layer that works alongside them.

What is Signal Chaos? Signal Chaos™ is the experience of a caregiver who has not yet developed Signal Literacy™, characterized by confusion, reactivity, exhaustion, and the feeling that their child's communication is random or intentionally defiant. It is the starting point for most parents, and it is what the framework is built to resolve.

What is a Signal Window? A Signal Window™ is a naturally occurring moment of regulated, interested, and available attention in which a child is most receptive to communication interaction and signal expansion. Parents learn to find Signal Windows early in the SIGNAL Path. In Stage 5, Anticipate Breakdowns, they learn to notice when a Signal Window starts to narrow, which is one of the earliest signs that overload is building.

Do I need to complete all six stages in order? The stages are cumulative, and the course teaches them in order: six modules, 24 lessons. Each stage builds on the skills developed in the ones before it, so Stage 3 works best on the interpretive foundation of Stage 2.

Can the framework work alongside my child's current therapy? Yes. The framework is designed to work alongside ABA, Floortime, SCERTS, TEACCH, and AAC. It provides the interpretive layer that helps those approaches respond to what the child is actually communicating.

What is the SIGNAL Repair Protocol? The SIGNAL Repair Protocol™ is the clinical procedure for any breakdown: five sequential steps grounded in Functional Communication Training research. Step 1, stop the demand. Step 2, regulate. Step 3, interpret the signal. Step 4, model the replacement. Step 5, re-engage. It is taught in Stage 5 of the SIGNAL Path.
