Screening Tools for School-Age Children

Researchers have established developmental screening tools that can be used to assess whether a school-age or older child needs to be referred to an expert for additional diagnostic testing.

Key Points
  • SCQ is a parental questionnaire with 40 yes-or-no items.
  • ASSQ is a 27-item, yes/somewhat/no-style questionnaire meant to assess the symptoms characteristic of high-functioning Autism Spectrum Disorders (ASDs) in children and adolescents.
  • The Childhood Autism Spectrum Test (CAST), also known as the Childhood Asperger Screening Test, detects Autism Spectrum Disorders (ASDs) in 5- to 11-year-old children by using a parental questionnaire to measure social andcommunication┬áskills.

To have autism spectrum disorder, a child must be diagnosed within the first couple years of life.


Many children are not diagnosed with autism spectrum disorder until after four years of age. Screening tools for school-age children are an important piece of the doctor's screening and diagnostic toolbox.
