The IQ of a nonverbal autistic person can vary widely, just like with verbal individuals. Being nonverbal does not mean a person has a low IQ. In fact, many nonverbal individuals with autism have average or even above-average intelligence but struggle with expressive language.
Traditional IQ tests often rely heavily on verbal responses, which can make it hard to accurately measure intelligence in nonverbal individuals. Fortunately, there are alternative, nonverbal assessments, like the Leiter International Performance Scale or Raven’s Progressive Matrices, that help provide a more accurate picture of cognitive ability.
It’s important to focus on a person’s strengths and potential, not just their ability to speak. With the right support, many nonverbal autistic individuals can learn to communicate using tools like AAC devices, sign language, or picture systems.
