Autism Screening/Diagnostics

There is no medical test to provide an autism diagnosis. Instead, autism-specific evaluations are administered by a trained specialist such as a child psychologist, developmental pediatrician, occupational therapist, speech and language pathologist, or other trained specialist.

From birth to at least 36 months of age, every child should be screened for developmental milestones during routine well visits. When a parent or screening results raises concerns about a child’s development, the doctor should refer the child to an autism specialist. A comprehensive diagnostic evaluation helps parents understand as much as possible about their child’s strengths and needs.

Often parents are the first to notice that their child is showing behaviors such as failing to make eye contact, not responding to his or her name or playing with toys in unusual, repetitive ways. For a description of early indicators of autism, visit our Learn the signs page.

Do not be afraid to voice your concerns and if you feel that your provider is not listening to your concerns, seek a second opinion or initiate an autism screening yourself. Many of our TAP partners provide autism screenings and diagnostic evaluations. Click on the button below to connect to your nearest TAP service provider.
