High functioning autism (HFA) is a non-medical term often used to describe people with autism who have an IQ score above 80 and who have the ability to speak, read and write.

Although many physicians and healthcare professionals have adopted the term “high functioning” to recognize this form of autism, there is actually no medical condition known as “high functioning autism.” A person diagnosed with HFA meets the same diagnostic criteria as do other people on the autism spectrum.  However, the person with HFA may just have an easier time communicating with others and carrying on more regular activities.
