Checklist for Autism in Toddlers (CHAT)

The Checklist for Autism in Toddlers, developed by the Autism Research Centre, is designed to be used by GPs or Health Visitors during the 18 month developmental check-up.

The CHAT was designed on the basis that by 18 months of age the majority of typically developing children initiate and respond to joint attention and pretend play, and that the absence of these behaviours might indicate the presence of autism.

You can download the checklist from the Autism Research Centre (ARC), Department of Developmental Psychiatry, University of Cambridge, provided that it is used for genuine research purposes, and provided due acknowledgement of ARC as the source is given.
