What is the IQ of a Nonverbal Autistic Person?

August 13, 2025

The IQ of a nonverbal autistic person can vary greatly, just like in the general population. Autism is a spectrum, and individuals with nonverbal autism may have intellectual abilities ranging from intellectual disability to average or above-average intelligence.

Being nonverbal doesn’t necessarily reflect a person’s cognitive abilities. Many nonverbal individuals with autism have strong skills in areas like visual processing, mathematics, or memory, even if they struggle with speech. In fact, some may use alternative communication methods, such as AAC devices or sign language, to express themselves.


It’s essential to understand that IQ tests may not fully capture a nonverbal individual’s abilities, as traditional assessments often rely on verbal communication. With ABA therapy, nonverbal individuals can develop communication skills, improving their ability to express themselves and engage in everyday activities.
