Why we don't say "high-functioning"
The phrase hides the thing you actually need described. What we write instead, and why.
“High-functioning” tells you nothing actionable. It does not say whether a child can cross a road, tolerate a dentist, or ask for help when frightened.
So we name the need instead: needs significant daily support, has a learning disability, cannot be left alone near water. Longer, and useful.
We also default to identity-first language — autistic child — because that is the clear majority preference among autistic adults. We never correct a parent’s own words.
