In addition, there needs to be available funding.

If an individual is determined eligible for services and there is no available funding, you will be put added to the No Paid Services (NPS) caseload. It is very important to request the services you or loved one needs. When new funding becomes available, DDA looks at those who have requested services. It’s called a Service Request List.

Getting a determination of eligibility from DDA to become a DDA Client

To apply for a determination of DDA eligibility, you will find detailed instructions and the forms you need to complete a DDA eligibility packet on the DDA website. The packet can be mailed to you or you can download them. If you call for an application, some information will be taken over the phone. The application and additional information and forms will be mailed to you for completion and/or signature.

You will be asked to provide any available school or medical records or sources of information that will assist in determining eligibility. Copies of other documents may be required. Upon request, DDA staff can assist you with completing the application. Please be aware that eligibility cannot be determined until DDA receives your signed application and all of the necessary information.
