Why Many Professionals
Avoid Autism Levels
DIAGNOSIS | INDEPENDENCE | WELL-BEING
DSM-5 introduced support levels for autism - but their misuse in everyday language has caused real harm to autistic people and their access to support.D
The Core Problem
Levels describe support needs -
not severity of autism itself
When people say "Level 1 autism" or "Level 3 autism," they often imply a fixed, ranked scale of how autistic someone is. This fundamentally misrepresents what the levels measure: how much support a person appeared to require in a specific context, at a specific time — which can change dramatically.
❌ Common Misreading
"Level 1 = mildly autistic"
This frames autism as a hierarchy of severity — as if a Level 1 person is "barely autistic" and a Level 3 person is the most autistic. It reduces a complex neurotype to a ranking, erasing individual experience and leading to denied support or dismissed struggles.
✓ What It Actually Means
"Level 1 = lower support needs observed"
The levels describe the amount of support a person appeared to need at the time of assessment, in the contexts assessed. A "Level 1" person may mask intensely, exhausting themselves. A "Level 3" person may thrive in the right environment. Neither number tells the full story.
What the DSM-5 Levels Actually Say
Each level refers to support needs observed — not a fixed trait of the person
Support Level 1 — "Requiring Support"
Without support, noticeable differences in social communication
May appear to cope in structured environments. Often misses the hidden social curriculum. Frequently misdiagnosed or dismissed as "not autistic enough." Many Level 1 autistic people experience profound exhaustion from masking and have significant unmet needs.
⚠ Often leads to under-support — struggles are invisible to observers
Support Level 2 — "Requiring Substantial Support"
Marked differences in verbal and nonverbal communication
Support needs are more visible in various settings. However, with the right supports in place — structured environments, sensory accommodations, communication tools — the same person may function very differently and need far less reactive support.
⚠ Need varies hugely depending on environment and available supports
