CAST — Childhood Autism Spectrum Test (Scott, Baron-Cohen, Bolton & Brayne)
Child Autism Screener (parent)
The CAST is a 37-item parent questionnaire for children aged roughly 4–11 years. It is widely used as a first-step autism screener.
Heads up: This is a parent-rated screening tool — not a diagnosis. A full autism assessment looks at multiple settings and a child's developmental history.
