Eligibility for services


A Developmental Disability is a neurological condition that primarily affects the brain. It originates in childhood and significantly impacts adaptive behavior, or everyday living skills. Developmental disabilities may include Intellectual Disability, Autism Spectrum Disorders, Cerebral Palsy, Down Syndrome, Epilepsy and other neurologically disabling conditions. Please contact the Intake Line for questions about other qualifying neurological conditions.


Conditions such as mental or emotional disorder, sensory impairment, substance abuse, personality disorder, learning disability or ADHD are not considered qualifying developmental disability diagnoses that can be used to determine eligibility. For questions about qualifying conditions, please call the DD Intake Line.


Eligibility is determined by gathering an applicant's developmental history and all historical documentation to determine if they meet requirements outlined in the Oregon Administrative Rules. OAR 411-320-0020 – Definitions and OAR 411-320-0080 (1) (16).

Eligibility documentation for school-age children and adults is reviewed to determine if they meet either the intellectual disability criteria or other developmental disability criteria. Intellectual disability criteria is determined by scores on standardized IQ testing and adaptive behavior assessments; while eligibility for other developmental disabilities is determined by diagnostic information and scores on standardized adaptive behavior assessments.  Please contact the Intake Line for questions about eligibility and criteria for young children.
