The first stage stratifies children into 3 group- low risk, medium risk, and high risk. Children who are medium risk go to the second stage for further clarification. A child whose score was greater than 3 at the first screening and greater than 2 on the second screening had a 47.5% risk of being diagnosed with autism spectrum disorder.
assess autism in children, adolescents, and adults The Autism Diagnostic Observation Schedule ( ADOS ) is a standardized diagnostic test for assessing autism spectrum disorder . The protocol consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and the person under assessment.
The Checklist for Autism in Toddlers (CHAT) is a psychological questionnaire designed to evaluate risk for autism spectrum disorder in children ages 18–24 months. The 14-question test is filled out by the parent and a pediatrician or physician and takes approximately 5 minutes to complete. [ 1 ]
The interview was also found to have adequate reliability across time. Research comparing ADI-R results of autistic children and children with other developmental disorders suggested that individual questions on the interview were slightly more valid when discriminating autism from intellectual disability than the algorithm as a whole.
Clinical judgment is helpful (e.g., for identifying pallor, clamminess, fussiness and other symptoms of illness) but development and developmental problems are usually far too subtle to simply observe. Most children with difficulties are not dysmorphic and so lack any visible physical differences from other children.
The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).

The Childhood Autism Rating Scale (CARS) is a behavior rating scale intended to help diagnose autism. CARS was developed by Eric Schopler, Robert J. Reichler, and Barbara Rochen Renner. The scale was designed to help differentiate children with autism from those with other developmental delays, such as intellectual disability.
Parents of 1,150 primary school aged children were sent the CAST questionnaire, with 199 responders and 174 taking part in the full data analysis. The results suggested that, compared to other screening tools currently available, the CAST may be useful for identifying children at risk for autism spectrum disorders, in a mainstream non-clinical sample.
