Moving Beyond Labels: Why “High Functioning Autism” Is Outdated

August 28, 2025

Why is high-functioning autism no longer used? The term “high functioning autism” is now outdated because it oversimplifies the autism experience and fails to capture the real challenges individuals face, regardless of IQ.



Reasons the Term Fell Out of Use

  • Oversimplification: “High functioning” mainly refers to IQ or language ability but ignores difficulties with daily living skills, social interaction, and emotional regulation.

  • Misleading Label: Individuals labeled high functioning may still need significant support—this term can minimize their struggles and reduce access to services.

  • DSM-5 Update: Modern diagnostic guidelines (DSM-5) classify autism by levels of support needed rather than functioning labels, focusing on personalized support.

  • Stigma and Harm: Many autistic advocates highlight how “high functioning” labels create harmful stereotypes and ignore the complexity and diversity within the spectrum.

  • Focus on Needs, Not Labels: The shift is toward individualized assessment and respect for each person’s unique strengths and challenges, helping tailor effective therapy.
