The Collaborative Autism School Assessment & Development Efforts (CASCADES) is a pioneering school-clinic evaluation model that brings together health providers and school districts to deliver medical autism diagnosis as an integrated part of the educational assessment process for underserved youth in their local community.
CASCADES’ mission is to address long standing autism-related healthcare access inequities by offering an alternative pathway to comprehensive evaluations, thereby enabling access to targeted interventions and services.
Using a collaborative cross-systems approach, we provide training, consultation, and partnership within community providers in identifying autism and supporting autistic youth and their families.
Come see us at the 2025 INSAR Annual Meeting at the Seattle Convention Center, Seattle, WA!
“The CASCADES Program: A school-clinic partnership addressing barriers to autism assessment among underserved youth”

CASCADES began in 2018 as a grass-roots effort between the Seattle Children’s Autism Center and the Bellevue School District to reach underserved students suspected of autism. Our clinical program operates through the SCAC, offering medical diagnosis and brief follow-up care for youth and families from our partnered “CASCADES school-teams” (i.e., contracted school districts).
We expanded in 2022 from one to five school districts, completing over 212 collaborative autism evaluations with predominantly Medicaid-eligible youth in their local schools. We have also trained over 35 school-team providers, which includes school psychologists and speech language pathologists.
To further our “reach,” CASCADES partnered with WA INCLUDE in 2024 to serve youth/families beyond the greater Seattle metro-area, in both rural and urban regions of Washington state where communities are historically under-resourced and marginalized.
Services we provide as part of contractual agreements between CASCADES (via SCAC) and our partnered school districts (or ESDs), include:
“The harsh reality is that 60% of underserved families wait over two years for an autism diagnosis, trapping them in a system that wasn’t built for them. Through our school-clinic partnership model, we’ve reduced wait times by 300% while cutting evaluation costs in half. This isn’t just about efficiency—it’s about transforming lives by making healthcare justice a practical reality for communities that have been systematically left behind.”

Only COE providers may prescribe ABA therapy for children covered by WA State Medicaid plans. COE providers can be pediatricians, family medicine physicians, ARNPs and licensed naturopathic doctors. Providers of other specialties including neurology, psychiatry, developmental pediatrics and licensed clinical psychologists may also be granted COE status without obtaining specific COE training. The WA State Health Care Authority decides who has COE status and grants this privilege. It should be noted that any provider can make an ASD “medical” diagnosis for a Medicaid child but the prescription of ABA services will only be honored by Medicaid if it was made by a COE provider.
More information:
Schools make their own assessment to determine school provided intervention services. They are not required to use a diagnosis from a medical provider but generally do so. There are no requirements as to what specific specialty, or specific autism training a provider needs to have obtained to make a diagnosis for the purposes of recommendations to schools.
Eligibility for services from the Developmental Disabilities Administration (DDA) are dependent on some specified diagnoses and a measure of functioning, generally adaptive skills. As of October 17, 2019, DDA has expanded the scope of who can provide a diagnosis of autistic disorder (DSM-IV-TR) or autism spectrum disorder (DSM-5) for the purposes of establishing DDA eligibility by including physician and ARNP COEs.
DDA will accept a diagnosis from any of the following professionals:
Note: DDA does not accept a diagnosis of autism from naturopathic physicians for the purpose of DDA eligibility.
