Stop Underestimating Them: The Hidden Power of Presuming Competence

Stop Underestimating Them: The Hidden Power of Presuming Competence

One of the most heartbreaking and pervasive misunderstandings in the world of special education and parenting is the assumption that a child who cannot speak also cannot understand. For decades, the medical and educational establishments have frequently looked at nonverbal autistic individuals and drastically underestimated their cognitive abilities. However, a massive paradigm shift is occurring within neuro-affirming care: the absolute necessity of presuming competence [7]. This is not just a feel-good slogan; it is a fundamental communication breakthrough. When we change our mindset to assume that a child understands everything happening around them, we completely alter the trajectory of their development and their self-worth.

What Does Presuming Competence Mean?

Presuming competence means starting from the unshakable belief that your child is capable of learning, thinking, understanding, and communicating, even if their body or neurology prevents them from demonstrating it in traditional, neurotypical ways [7]. It means speaking to a nonverbal teenager like a teenager, not like a toddler. It means explaining complex concepts to them, involving them in family decisions, and never speaking about them in front of them as if they are invisible. We must always assume competence when it comes to nonverbal autistic individuals, recognizing that their receptive language (what they understand) is often vastly superior to their expressive language (what they can say) [7].

The Danger of Underestimation

When we fail to presume competence, we severely limit a child's potential. If a teacher assumes a child cannot read simply because they cannot read aloud, that child will never be given complex books. They will be trapped in a curriculum of endless, repetitive basic skills, leading to profound boredom and often resulting in challenging behaviors. Behavior is communication, and a child acting out is frequently a highly intelligent individual screaming, "I am bored, and you are treating me like a baby!" By underestimating them, we inadvertently build a cage around their potential.

Unlocking the Inner Voice

The true breakthrough happens when we match the presumption of competence with robust, neuro-affirming communication tools. We are now seeing incredible success as spelling, typing, and other alternative communication modalities are helping nonverbal people finally express themselves [7]. Whether it is through a robust Augmentative and Alternative Communication (AAC) device on an iPad, a rapid prompting letterboard, or simple text-to-speech apps, giving a child a voice changes everything. When provided with these tools, they routinely show the world just how intelligent, capable, and incredible they truly are [7].

Actionable Takeaways for Parents

• Change How You Speak: Never talk about your child in front of them as if they aren't there. Always assume they understand every word.
• Provide Robust AAC Early: Do not wait for spoken language to emerge before introducing alternative communication tools. AAC does not hinder speech; it builds language.
• Demand Age-Appropriate Material: Advocate for your child at school to ensure they are receiving intellectually stimulating, age-appropriate educational materials, regardless of their verbal output.
• Celebrate All Modalities: Validate every form of communication—whether it is a typed word, a pointed finger, or a localized sound. All communication is valid.

Scientific Context

The principle of presuming competence is strongly validated by emerging research in autistic neurology and communication sciences. Recent studies utilizing advanced eye-tracking and neuroimaging technologies have demonstrated that a significant percentage of minimally verbal autistic individuals possess intact, and sometimes advanced, language comprehension and literacy skills that standard behavioral assessments completely fail to capture [Jaswal et al., 2020]. The discrepancy between motor execution (speech) and cognitive processing is a well-documented phenomenon. Furthermore, access to robust Augmentative and Alternative Communication (AAC) has been shown to exponentially accelerate expressive language development without diminishing natural speech production [Romski et al., 2015; Smith et al., 2024]. Therefore, presuming competence is not merely an ethical stance; it is an evidence-based clinical imperative.
