To request an application for Intellectual and Developmental Disability (I/DD) services, call 503-846-4737. Our intake staff will send an application to you.
Anyone can assist with making a referral. Written consent is required from the person or their legal guardian to start the process. All I/DD services are voluntary.
You will complete the application and return it to our office. There may be other information, like psychological testing, to provide as well. Our eligibility specialist staff can help you with the application. They can also help request any tests and evaluations that are needed to make a determination.
Once the eligibility specialist makes a determination, you will receive a notice in the mail. If you are eligible for I/DD services, a services coordinator will be assigned. Your services coordinator will tell you more about the services available to you.
If you do not agree with an eligibility determination, you have the right to request a hearing. Please visit the Office of Developmental Disabilities Services (ODDS) Administrative Hearings website for more information.
The criteria for intellectual and developmental disability eligibility is the same throughout Oregon. Eligibility specialists must use the Oregon Administrative Rules (OARs) to determine eligibility. Full definitions of intellectual and developmental disabilities are found in OAR 411-320-0020.
Standardized testing of intellectual functioning and adaptive behavior is used to determine the presence of an intellectual disability. Licensed clinical or school psychologists complete the testing. To be considered an intellectual disability, the following criteria must be met:
- Begin before 18 years of age
- Reflect Intelligence Quotient (IQ) testing scores below 75
- Individuals with IQ scores between 65 and 75 may qualify if there is testing that shows a significant impairment in adaptive behavior. Adaptive behavior refers to daily living skills, such as communication, grooming, dressing, and safety.
Developmental disabilities are significant mental or physical impairments that begin in the brain. Diagnoses from qualified professionals are used to make the determination. To be considered a developmental disability, the following criteria must be met:
- Begin before 22 years of age
- Be expected to continue indefinitely
- Cause significant impairment in adaptive behavior. Adaptive behavior refers to daily living skills, such as communication, grooming, dressing, and safety.
The assigned eligibility specialist can help explain more about the rules that apply. More information about eligibility is available at the Office of Developmental Disabilities Services (ODDS) website.
