Clinical Scales

The CHAT is a highly accurate and elegant autism screening tool for early autism diagnosis. Study findings indicate that CHAT is 85% accurate in diagnosing children with autism and 100% accurate in diagnosing a developmental delay in general.

The CHAT can be used for children aged 18 months of age or older.

The CHAT was developed by Professor Simon Baron-Cohen and colleagues.

You can also download a printable version , or continue with the The Checklist for Autism in Toddlers.
