High-functioning autism (HFA) is neither an official diagnosis nor is there an agreed-upon definition of what the term means. In the broadest sense of the term, high-functioning autism may mean any of the following:
- A person with relatively mild symptoms which, despite their mildness, are significant enough to merit an autism spectrum diagnosis.
- A person with autism whose IQ is higher than 70
- A person with autism who is successfully navigating a typical school or work environment
- A person who is able to mask symptoms of autism successfully so they have in expected ways and can “pass” for neurotypical
