Why Is High Functioning Autism No Longer Used? Understanding the Shift

August 8, 2025

The term “high functioning autism” was once common to describe autistic individuals without intellectual disability who show strong language skills. But today, many experts and the autism community are moving away from this label. So, why is high functioning autism no longer used?


Research reveals that the label oversimplifies the complexities of autism. People classified as “high functioning” often still face significant daily challenges in communication, social interactions, and adaptive skills like managing personal care or transportation. The term mainly focused on IQ, ignoring how much support a person might actually need.


Studies show that IQ is a weak predictor of everyday functioning, meaning someone with a high IQ may still struggle with essential life skills. Labeling someone as “high functioning” can mistakenly minimize their difficulties and result in less access to necessary services or support.


Moreover, many autistic advocates point out that functioning labels can be misleading and stigmatizing. They don’t reflect individual strengths and challenges, nor do they align with more personalized support assessments used today, such as the DSM-5 levels based on support needs.
