Presuming Competence: What It Means and Why It Changes Everything

Last spring, a mom named Rachel in Portland told me a story that stuck. Her son Eli was four and a half, nonspeaking, and had just been assigned a new SLP at his preschool. On the first visit, the therapist sat across from Eli, looked at him, and said: "Eli, I'm going to explain how our sessions work, because I think you want to know what's happening." Rachel started crying in the observation room. Not because the sentence was remarkable. Because in eighteen months of services, no professional had ever talked directly to her son.

That's what presuming competence is. And the fact that it can still surprise a parent tells you how rare it remains.

Presuming competence means acting as if your child understands what's happening around them, even when their output (speech, motor skills, behavior) hasn't shown it yet. For autistic kids, especially nonspeaking and minimally speaking kids, this one shift in adult mindset does more than almost any therapy session.

It is the most important concept in autism family life that almost nobody learns early enough.

What It Actually Means, Stripped Down

When you presume competence, you include your child in conversations. You explain what's happening before it happens. You read books at age level. You speak to them, not about them while they're in the room. You hold the same intellectual respect you'd hold for any other person their age.

The opposite looks like talking over a nonspeaking child, using baby talk well past the age it serves anyone, skipping explanations because "they won't get it," and treating the child as an object of intervention rather than a participant in their own life.

Here's the thing: the math on this is lopsided and it favors one direction.

The cost of presuming competence when you're wrong? Your child got more language input than they needed. That's it.

The cost of presuming incompetence when you're wrong? Your child spent years hearing adults underestimate them. Discuss them. Write them off. And miss the language input that would have helped them grow.

Default to competence. Every time.

The Gap Between Understanding and Speaking

Receptive language (what a child understands) almost always outpaces expressive language (what they can produce). In autistic kids, that gap is often far wider than standard milestone charts suggest.

Many autistic adults who began life nonspeaking have written, typed, or spelled about what it was like to hear adults discuss them in front of their faces, doubt their intelligence, and give up on them. They remember it. They felt it. They simply couldn't respond, so the adults assumed nothing was happening inside.

Think of it like being anesthetized during surgery but still conscious. Your mouth won't move. Your eyes won't open. But everything registers. That's an extreme version, but the principle applies: motor output is not a proxy for cognitive presence.

Presuming competence isn't a clinical technique. It's a basic act of respect that happens to also be the single most useful thing you can do for language development.

What This Looks Like on a Tuesday Morning

The concept is abstract until you see the shape of it in daily life. Some swaps:

Instead of "She doesn't understand, so I don't bother explaining," try explaining anyway. "We're going to the store. We'll get milk and apples. Then we come home."

Instead of reading only baby board books to your five-year-old, try reading at age level too. Picture books for older kids. Chapter books with illustrations. Books your child would hear in a typical kindergarten classroom.

Instead of narrating your child in third person while they sit right there ("She's having a hard time today, she's been stimming a lot"), try talking to them directly. "You've been stimming a lot today. I think you might be overwhelmed. Want to take a break?"

Instead of the hushed, pitying tone when introducing them to other adults, try speaking about them the way you'd speak about any kid. "This is Maya. She loves dinosaurs and she communicates with her tablet."

Instead of treating silence as an absence of opinion, try asking, then waiting. Give a full ten seconds. Watch for any response, including ones that aren't speech.

Instead of "She's nonverbal and low-functioning," try describing what's actually true. "She uses AAC for most of her communication." One tells another person something useful. The other tells them something inaccurate and limiting.

When Behavior Screams the Opposite

Here's where presuming competence gets genuinely hard.

A child who melts down at a transition can look like they didn't understand the warning. A child who walks away mid-conversation can look like they weren't following. A child who doesn't answer a question can look like they didn't register it.

But in autistic kids, behavior almost always means something other than "I didn't understand." Meltdowns are usually about regulation, not comprehension. Walking away is often about sensory load, not disinterest. Not answering is about motor planning, processing time, or the social cost of responding, not the absence of an answer.

Presuming competence means looking at the behavior and asking, "What is this telling me about my child's internal state?" rather than "How much did my child comprehend?"

That reframe changes everything. It turns a confusing moment into a readable one.

The Language Exposure Multiplier

This is the piece that doesn't get enough attention. The language exposure a child receives is directly downstream of how adults treat them. It's a feedback loop, and it runs in both directions.

Adults who presume competence:

Adults who presume incompetence:

Over a childhood, the difference amounts to thousands of hours of high-quality language input. That input is the substrate on which expressive output eventually gets built. Presuming competence isn't only an ethical stance. It is a language acquisition strategy, and a powerful one.

I'll go a step further and say something that might sound strong: if you had to pick one thing to change about how you interact with your autistic child who isn't talking yet, and you could only pick one, this would be it. Not any app. Not any therapy schedule. This.

Bringing It Into a Household That Hasn't Been Doing It

Most of us didn't grow up with this framing. Adjusting takes practice, and some honest self-observation. A few starting points:

  1. Talk to your child the way you'd talk to any kid their age, every day, for one week. Notice when it feels strange. That feeling is the old assumption surfacing. Sit with it.
  2. Stop talking about your child in front of them. If you need to discuss behaviors or concerns with a partner, do it later, behind a closed door.
  3. Read one book per day that's above their current "level." See what happens. Many parents are surprised by what holds their child's attention when the material is actually interesting.
  4. Include your child in decisions. Ask. Wait. Honor the answer, including a silent one.
  5. Name this shift for the other adults in your child's life. Grandparents, teachers, therapists. You don't need to lecture. Just say: "We're working on treating Eli like he understands everything, because we think he does." Most people will follow your lead once they see the change.

When Professional Help Fits

This is mostly a household shift, not a clinical one. But a few situations where a professional can help:

Frequently Asked Questions

What if my child really doesn't understand something? You explain it differently next time. You don't stop explaining. The cost of a "wasted" explanation is near zero. The cost of a withheld one compounds over years.

Is presuming competence the same as ignoring my child's challenges? No. You can presume competence and still acknowledge real support needs. "She understands everything I'm saying" and "She needs support to handle the grocery store" are both true at the same time. They address different things.

What if I've been presuming incompetence for years without realizing it? Most parents have, at least in some areas. The repair isn't a single conversation or apology. It's a daily shift. Start now. Your child has time, and they will feel the change within weeks.

Does presuming competence apply to kids with intellectual disability too? Yes. The default is identical. Presume competence. Adjust based on what you actually observe over time, not on a diagnostic label assigned at age three.

My partner or family member won't get on board. What do I do? Lead by example for a couple of months. Most people come around when they watch it work. If they don't, keep advocating, especially in the spaces your child occupies most: school, therapy, family gatherings.

How does this connect to AAC and communication tools? Presuming competence is the mindset. AAC is one of the tools that follows from it. If you assume your child has things to say, you give them a way to say them. The two go hand in hand.

Is there research behind this, or is it just a philosophy? Both. The principle is rooted in decades of work in disability rights and inclusive education. The evidence on receptive-expressive gaps in autism, the impact of language-rich environments, and the accounts of nonspeaking autistic adults all converge on the same conclusion. Presume competence.
