A common tool used to assess the risk of Autism Spectrum Disorder (ASD) is a parent report screening tool known by the name M-CHAT-R, which is an abbreviation of Modified Checklist for Autism in Toddlers. It can be administered during a good child visit and the resulting scores can be used by specialists and other professionals alike to look out for risks of ASD.
The second edition of the Childhood Autism Rating Scale is used on children in the age range of two to six years old. This helps in distinguishing autistic children from children who face other developmental disorders. The results from this scale provide parents with diagnostic feedback, characterizing functional profiles, and guiding intervention planning.
This version of the above-mentioned scale is used on children above the age of six, who are verbally fluent. This version of the scale was developed as an alternative to the original to identify high functioning children.
