What Is the IQ of a Nonverbal Autistic Person?

August 7, 2025

The IQ of a nonverbal autistic person can vary widely, just like in any other group. It’s important to understand that being nonverbal does not mean a person has a lower IQ. Many individuals with autism who are nonverbal may have average or above-average intelligence but face challenges in communication.

IQ tests traditionally measure language-based skills, which may not reflect the true abilities of someone who struggles with verbal expression. Nonverbal individuals often have unique strengths in areas like visual processing, pattern recognition, and problem-solving that may not be captured by standard IQ tests.

ABA therapy can help nonverbal children develop communication skills through alternative methods, like sign language or communication devices, allowing them to express their thoughts and ideas more effectively.

At Little Rays ABA, we focus on helping nonverbal children gain essential communication and behavioral skills tailored to their individual strengths. Our goal is to support every child’s growth, regardless of their verbal abilities.
