Filling out an application on behalf of someone you love can feel heavy. You want to get it right, and you may not be sure where to begin. The good news is that the process follows a clear set of steps. Take them one at a time, keep copies of everything, and remember that it is okay to ask questions along the way.
Start with the right application pathway
Arizona DDD has different eligibility pathways based on age. For children under age three, families are encouraged to begin with the Arizona Early Intervention Program (AzEIP). Families of older children and adults can use the DDD eligibility application and supporting documentation described by Arizona DES.
Step 1: Review age-specific requirements
For children ages three through five, DDD evaluates qualifying conditions or developmental delays and other requirements. For applicants age six and older, DDD generally looks at a qualifying developmental disability that began before age 18, its expected duration, and substantial limitations in daily living skills. Reviewing the requirements before you gather records can help you avoid an incomplete submission. Our guide, Who Qualifies for DDD Services in Arizona?, breaks these down.
Step 2: Gather supporting records
Documentation depends on the applicant's situation, but common records include:
- ✓A signed DDD application.
- ✓Proof of Arizona residency and citizenship or lawful presence.
- ✓Any insurance information you have.
- ✓Medical or psychological evaluations.
- ✓School records, such as an Individualized Education Program (IEP) or multidisciplinary evaluation.
- ✓Legal paperwork, if a guardian is applying for an adult.
A simple folder or binder, labeled by type of record, can save a lot of stress later. Make copies before you send anything.
Step 3: Submit the application
Arizona DES states that families may email a completed application and supporting records to DDDApply@azdes.gov, or deliver materials to a DDD office. Use the official eligibility packet and current instructions on the DES Determine Eligibility page (opens in a new tab), rather than an unofficial form from a third-party website.
Step 4: Respond to requests for information
An eligibility specialist may reach out to clarify information or ask for more records. Responding promptly matters, because missing records can delay the review. Save a copy of your application and write down the date you submitted it, along with the name of anyone you speak with.
Step 5: Understand the decision and next steps
DDD decides whether the applicant meets its eligibility criteria. Eligibility for DDD does not by itself guarantee ALTCS eligibility or a particular amount of funded attendant care, habilitation, or respite. If an application is denied, the notice should explain why and how to request a review.
If your loved one is found eligible, a Support Coordinator will be assigned to help create a person-centered plan. Learn what to expect in What Does an Arizona DDD Support Coordinator Do?
Taking care of yourself through the process
Waiting on a decision can be stressful. If you are a parent or family member already providing daily care, you may want to learn about our DDD family caregiver program, which can allow eligible family members to be paid for the care they provide once services are in place.
