Is Level 2 Autism High Functioning or Severe Autism?

January 29, 2026

Level 2 autism is considered “requiring substantial support.” It is not the same as what people often call “high functioning,” and it is also not the most severe level. Instead, it falls in the middle of the autism spectrum in terms of support needs.


Individuals with Level 2 autism may have noticeable challenges with communication, social interaction, and flexibility. They might speak in short phrases, struggle with back-and-forth conversation, or become overwhelmed by changes in routine. Repetitive behaviors, sensory sensitivities, and emotional regulation difficulties are also common. These challenges can make daily life, school, and social situations harder without consistent support.

At the same time, Level 2 autism does not mean a person lacks potential. With structured teaching, therapy, and the right accommodations, many individuals make meaningful progress in communication, independence, and coping skills.


Understanding the level helps families and professionals choose the right supports, not labels like “high” or “severe.”
