How High-Functioning Autism is Diagnosed

June 16, 2025

High-functioning autism isn’t a formal diagnosis, but it’s a term many people use to describe individuals on the autism spectrum who have average or above-average intelligence and can handle many day-to-day tasks. 


Even though they may seem “typical” in many ways, they often face challenges with social skills, sensory sensitivity, or repetitive behaviors. 

So how is it diagnosed?


What the Diagnosis Involves

There’s no single test for autism. Instead, professionals rely on a mix of observations, interviews, and questionnaires.


A psychologist, developmental pediatrician, or neurologist will typically assess a person’s developmental history, behavior, and communication skills.


For children, the process might include watching how they play, interact, and respond to different situations. Parents often complete forms about what they’ve noticed at home or in school. 


For teens and adults, evaluations may involve talking through personal challenges, social interactions, and emotional regulation.


Common tools used during diagnosis include the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R). These help specialists look for patterns of behavior that align with autism.


Remember: "high-functioning" doesn’t mean “less support needed.” Everyone on the spectrum is unique, and the level of support can vary widely.
