Screening and Diagnosis

The CDC currently estimates that 1 out of 68 children will be diagnosed with an Autism Spectrum Disorder, or ASD, and boys are 4 1/2 to 5 times more likely to be diagnosed than girls. Autism Spectrum Disorder is a neurodevelopmental disorder, and children diagnosed with ASD share similar challenges with communication, social ability, and behavior. Because no two individuals with ASD exhibit exactly the same characteristics, professionals must approach diagnosis cautiously and conservatively.

Diagnosis for ASD is done by observing and interacting with the child or adult and administering specific autism screening and diagnostic instruments. The resources in this section are designed to help you understand the red flags or warning signs of ASD, when and how individuals should be screened for evaluation, and how an individual may be diagnosed with ASD.

Their website also houses a list of statewide Assessment Centers.

Guides and Fact Sheets
