Presume Competence: The Foundation of AAC Success

Why believing in your child's potential is the first step to unlocking their communication.

What Does "Presume Competence" Mean?

Presuming competence means assuming that a person can learn, understand, and communicate — even if we can't see evidence of it yet. It's approaching every AAC user with the belief that they have thoughts worth sharing.

The Problem with Underestimating

When we underestimate AAC users:

  • We provide limited vocabulary ("They only need basic needs")
  • We stop teaching ("They've reached their potential")
  • We speak over them ("They can't understand anyway")
  • We make decisions for them ("They can't have preferences")

The Power of High Expectations

Research consistently shows:

  • Children rise to expectations
  • Limited systems lead to limited communication
  • Adults often underestimate cognitive abilities of non-speaking children

Real Stories of Presuming Competence

Story 1: A girl considered "low-functioning" was given access to a robust AAC system. Within months, she was writing poetry.

Story 2: A boy who was only given a device with 20 basic words. When upgraded to a full system, he immediately started forming complex sentences about his interests.

Story 3: A teenager who everyone assumed couldn't read. With AAC, she demonstrated she had been reading all along — just unable to show it.

How 2KTalk Presumes Competence

Full Language Access

Every user gets access to thousands of words, not a limited "starter set."

Growth-Ready Design

The system expands as the user grows — no artificial ceilings.

Literacy Integration

Reading and spelling tools for users who are ready.

Respect in Design

Age-appropriate vocabulary options, not "baby" symbols for older users.

For Parents: Practical Steps

1. Offer Robust Vocabulary

Don't limit the device to "basic needs." Include emotion words, opinion words, social language.

2. Wait for Responses

Give your child time to formulate and express thoughts. Don't answer for them.

3. Treat Communication as Valid

If they say it, respond to it — even if you're not sure they meant it.

4. Expose to Rich Language

Read to them, talk to them, include them in conversations.

5. Fight Low Expectations

Challenge anyone who says "they'll never..." or "they can't..."

The Competence-Performance Gap

Not speaking ≠ Not thinking Not responding ≠ Not understanding Not performing ≠ Not capable

Our job is to bridge the gap between competence (what they CAN do) and performance (what they SHOW us) — not to assume the gap doesn't exist.

A Final Thought

The worst that happens if you presume competence and you're wrong? You've treated someone with dignity and given them opportunities.

The worst that happens if you presume incompetence and you're wrong? You've limited a capable mind and denied them a voice.

Always presume competence.
