Screening Tools

Screening tools are used to help identify children who might have developmental delays, such as autism.

Some screening tools (such as the Childhood Autism Spectrum Test) are relatively simple and are designed to be used by anyone (including parents and carers).  Other screening tools (such as the Screening Tool for Autism in Toddlers and Young Children) are more complex and are designed to be used by professionals who have experience with autism.

Please note that screening tools cannot give firm evidence of developmental delays, and they cannot be used to make a diagnosis. A positive screening result should be followed by a thorough assessment, which may lead to a formal diagnosis.

Specific autism screening tools commonly used in the UK include

  • The Childhood Autism Spectrum Test (CAST) - formerly known as the Childhood Asperger Syndrome Test
  • The Modified Checklist for Autism in Toddlers (M-CHAT) - formerly known as the Checklist for Autism in Toddlers (CHAT)
  • The Pervasive Developmental Disorders Screening Test (PDDST)
  • The Screening Tool for Autism in Toddlers and Young Children (STAT) -  formerly known as the Screening Tool for Autism in Two-Year-Olds
  • The Social Communication Questionnaire (SCQ) - formerly known as the Autism Screening Questionnaire (ASQ)

There are numerous other autism screening tools, some of which are listed below.  If you know of any other screening tools we should include in this section please email info@researchautism.net.  Thank you.
