What Are Early Intervention Programs?
Early intervention programs are specialized services designed to support infants and toddlers who have developmental delays or disabilities, including autism spectrum disorder (ASD). The goal is to provide therapy and support as early as possible-ideally before age 3-to help children develop essential skills and reach their full potential. In Arizona, these programs are coordinated through state agencies like the Arizona Early Intervention Program (AzEIP) and the Division of Developmental Disabilities (DDD).

Why Early Intervention Matters for Children with Autism
Research shows that early, intensive intervention can lead to significant improvements in communication, social skills, and behavior for children with autism. Applied Behavior Analysis (ABA) therapy, in particular, is evidence-based and most effective when started early. Arizona's early intervention programs aim to identify delays quickly and connect families with appropriate therapies, including ABA, speech-language pathology, and occupational therapy.
Arizona's Early Intervention Programs: A Closer Look
The Arizona Early Intervention Program (AzEIP)
AzEIP is the state's lead agency for early intervention under Part C of the Individuals with Disabilities Education Act (IDEA). It serves children from birth to age 3 who have a developmental delay or a diagnosed condition that is likely to result in a delay. Services are family-centered and provided in natural environments like the home or daycare. AzEIP coordinates evaluations, service planning, and referrals to providers.
Division of Developmental Disabilities (DDD)
For children age 3 and older-and for some younger children with significant needs-the Arizona DDD offers ongoing support. DDD provides case management and funding for therapies, including ABA, for eligible individuals with autism or other developmental disabilities. Eligibility is based on diagnosis and functional need. Families often transition from AzEIP to DDD around age 3.
AHCCCS (Arizona Medicaid) and Insurance Coverage
AHCCCS, Arizona's Medicaid program, covers early intervention services for eligible children. Many private insurance plans also cover ABA therapy and other early interventions due to Arizona's autism insurance mandate. Families should check their specific plan benefits. The Apply for ABA service can help you understand coverage options and find providers who accept your insurance.

How to Access Early Intervention in Arizona
Step 1: Recognize the Signs
If you notice your child is not meeting developmental milestones-such as not babbling by 12 months, not pointing by 18 months, or losing skills they once had-talk to your pediatrician. You can also contact AzEIP directly for a free evaluation.
Step 2: Request an Evaluation
Call AzEIP at 1-888-439-5609 or visit their website to request a developmental evaluation. This is free and does not require a doctor's referral. If your child qualifies, a service coordinator will help develop an Individualized Family Service Plan (IFSP).
Step 3: Choose Services and Providers
Based on the IFSP, you can select therapies such as ABA, speech therapy, or occupational therapy. For ABA, you'll want a Board Certified Behavior Analyst (BCBA) to oversee the program. Apply for ABA is a free service that matches families with vetted BCBA-led providers in Arizona, saving you time and stress.
Step 4: Transition at Age 3
Around your child's third birthday, AzEIP will help transition to school-based services (through the local school district) or to DDD if your child qualifies. DDD provides ongoing case management and funding for therapies.
What to Expect from Early Intervention Services
Evaluations and Assessments
Initial evaluations typically cover cognition, communication, motor skills, social-emotional development, and adaptive behavior. For autism-specific concerns, a diagnostic evaluation may be needed. AzEIP uses standardized tools and input from parents.
Therapy Sessions
Services are usually provided in your home, daycare, or community. ABA therapy may involve one-on-one sessions with a behavior technician under BCBA supervision. Speech and occupational therapy are also common. Frequency varies based on the child's needs-some children receive several hours per week.
Family Training and Support
Early intervention is family-centered. You'll receive coaching on how to support your child's development in daily routines. Parent training is a key component of effective ABA programs.

Costs and Insurance: What You Need to Know
AzEIP services are free or low-cost based on a sliding fee scale. Many families pay nothing. DDD services are funded through state and federal dollars, and there may be a family cost share based on income. Private insurance often covers ABA therapy, but you may have deductibles or copays. AHCCCS covers early intervention with no cost to eligible families. Always verify coverage before starting services. Apply for ABA can help you navigate insurance questions and find providers who accept your plan.
Practical Tips for Arizona Families
- Start early: Don't wait for a formal diagnosis. If you have concerns, request an evaluation from AzEIP.
- Keep records: Maintain copies of evaluations, IFSPs, and insurance documents.
- Ask about waitlists: Some providers may have waitlists, so apply to multiple if needed.
- Use free services: Apply for ABA can match you with BCBA-led providers at no cost.
- Connect with support groups: Organizations like the Autism Society of Arizona offer parent networks.
Common Mistakes to Avoid
- Waiting for a diagnosis: You can start early intervention without an official autism diagnosis.
- Ignoring insurance benefits: Know your plan's coverage for ABA and other therapies.
- Overlooking DDD eligibility: Even if your child is under 3, apply for DDD if they have significant needs.
- Not transitioning smoothly: Work with your AzEIP coordinator to plan the transition to school or DDD services at age 3.
