Autism Diagnostic Entry Clinic


Provides a comprehensive and multi-disciplinary diagnostic assessment of children or youth (5 years to 18 years of age) who present with a concern of autism (referred to as autism spectrum disorder, or ASD for short). Recommendations for services and treatment planning based on the child’s diagnosis are offered.


  • Provide an Autism specific evaluation that includes all the components of the Thompson Center best practice model of care.

  • Provide ADOS-2 (a gold-standard autism test which is administered by a research reliable clinician), cognitive assessment, adaptive functioning, and other necessary psychological assessments to answer the question of whether the child has autism or not.
  • Establish a relationship with a physician who will provide long term follow up care for all children with ASD.
  • Provide children and families with comprehensive recommendations families can use to guide them on accessing necessary resources to give their child the best chance for improvement over time.
