Arizona Part C Plans: A Parent's Guide to Early Intervention

In short: Arizona's Part C early intervention program, called AzEIP (Arizona Early Intervention Program), provides free or low-cost developmental services for children under 3 with delays or disabilities. You can self-refer, get an evaluation, and if eligible, receive a plan with services like speech, occupational, and ABA therapy. Early help can make a big difference, and your service coordinator can guide you through the process.
Key takeaways
- AzEIP is Arizona's Part C program for children under 3 with developmental delays or disabilities.
- You can refer your child directly - no doctor's referral needed.
- Eligibility is based on a developmental evaluation, not income.
- Services are provided at no cost to families, though some may use insurance.
What Are Arizona Part C Plans?
If you have a child under three years old and you're worried about their development, you've likely heard about 'Part C' or 'early intervention.' In Arizona, this federal program is known as the Arizona Early Intervention Program (AzEIP). Part C plans are not a single document but a set of services and supports designed to help infants and toddlers with developmental delays or disabilities learn and grow alongside their peers.
Think of it as a safety net. It's there to catch children early, before challenges become bigger. The goal is simple: provide the right help at the right time to maximize your child's potential.

Why Early Intervention Matters (and How It Helps)
The first three years of life are a period of incredible brain growth. Connections are forming at lightning speed. Early intervention takes advantage of this 'plasticity' - the brain's ability to change and adapt. By addressing delays early, we can often reduce the impact they might have later.
For a child with autism, for example, early intervention can significantly improve communication, social skills, and behavior. It's not about 'fixing' your child - it's about giving them the tools and support they need to thrive. And for you, as a parent, it provides a roadmap and a team of professionals to walk alongside you.
Who Qualifies for AzEIP? Eligibility Explained
Eligibility for AzEIP is based on two main criteria:
- Developmental Delay: Your child has a 50% or greater delay in one or more areas of development. These areas include cognitive, physical, communication, social-emotional, or adaptive skills.
- Established Condition: Your child has a diagnosed physical or mental condition that has a high probability of resulting in a developmental delay. This includes conditions like Down syndrome, cerebral palsy, or autism spectrum disorder.
You don't need a doctor's referral to start the process. You can contact AzEIP directly and ask for an evaluation. This evaluation is free and confidential. It's important to remember that eligibility is not based on income. Any family can access these services.

How to Get Started: A Step-by-Step Guide
Navigating a new system can feel overwhelming, but the process is designed to be as simple as possible. Here's what you can expect:
Step 1: Make a Referral
Call AzEIP or your local regional office. You can also ask your pediatrician, but it's not required. The team will take some basic information about your child and your concerns.
Step 2: The Evaluation
Within 45 days of your referral, AzEIP will conduct a comprehensive evaluation. This includes a developmental assessment and a review of your child's medical history. You'll be asked about your daily routines and any concerns you have. This is a two-way conversation, not a test your child passes or fails.
Step 3: The IFSP Meeting
If your child is found eligible, you'll meet with a team to develop an Individualized Family Service Plan (IFSP). This is a written document that outlines your child's strengths and needs, the goals you have for them, and the specific services they will receive. You are an equal partner in this process. Your input is not just welcome - it's essential.
Step 4: Services Begin
Once the IFSP is signed, services can start. The plan is reviewed at least every six months, and you can request changes at any time. The goal is to make sure the plan continues to meet your child's evolving needs.
What Services Does AzEIP Provide?
AzEIP offers a wide range of services, all designed to support your child's development in natural settings - meaning where your child already spends their time, like home or daycare. Common services include:
- Speech-Language Therapy: For communication and feeding challenges.
- Occupational Therapy: To help with fine motor skills, sensory processing, and daily living activities.
- Physical Therapy: For gross motor skills like crawling, walking, and balance.
- Developmental Instruction: A specialist who works on cognitive and social skills through play.
- Applied Behavior Analysis (ABA): A scientifically-backed approach to understanding and changing behavior, often used for children with autism.
- Family Training and Support: Coaching to help you understand your child's needs and implement strategies at home.
ABA therapy is a key service for many children on the autism spectrum. It can help with communication, social skills, and reducing challenging behaviors. If you think ABA might be right for your child, you can request it as part of your IFSP.

Costs and Insurance: What You Need to Know
This is often the biggest worry for parents. The good news is that AzEIP services are provided at no cost to families. The program is funded through federal and state dollars, so you won't receive a bill for the evaluation or the services themselves.
However, there are some nuances to be aware of:
- Medicaid: If your child is on Arizona's Medicaid program (AHCCCS), AzEIP may bill AHCCCS for certain services. This is a funding mechanism, not a cost to you.
- Private Insurance: AzEIP may ask for your private insurance information to see if they can bill for some services. This is voluntary, and you won't be charged co-pays or deductibles. The program cannot deny services if you don't provide insurance.
- ABA Therapy: While AzEIP can provide some ABA, it may be limited in scope. For more intensive ABA (like 20-40 hours per week), you may need to look to private providers. Many private insurance plans in Arizona cover ABA for autism, and AHCCCS also covers it. If you go this route, a free service like Apply for ABA can help you find a vetted, BCBA-led provider in your area.
AzEIP vs. School-Based Services: What's the Difference?
It's common to confuse early intervention with special education. They are related but distinct.
AzEIP (Part C) serves children from birth to age 3. The focus is on the whole family, and services are provided in your home or community.
Special Education (Part B) starts at age 3. At that point, your child may transition to your local school district, which is responsible for providing services through an Individualized Education Program (IEP). The IEP is more school-focused, and services are often provided at a school site.
Planning for this transition should start around your child's second birthday. Your AzEIP service coordinator will help you navigate this change, but it's good to be aware of it early.
Mistakes to Avoid in the Early Intervention Process
You are your child's best advocate. Here are some common pitfalls to watch out for:
- Waiting to See: 'He'll catch up' is a risky mindset. Early intervention is most effective when started early. If you have a concern, get an evaluation. It's free and can provide peace of mind.
- Not Speaking Up: You know your child better than anyone. If you feel a service isn't working or a goal is off-target, say something. The IFSP is a living document that should change as your child does.
- Ignoring the Transition: The move from Part C to Part B (or to other services) can be bumpy if you don't plan. Start talking about it months in advance.
- Forgetting About ABA: Many parents don't realize ABA is an option within early intervention. If your child is diagnosed with autism, ask about it. And if AzEIP can't provide the intensity you need, look for a private provider.
How to Make the Most of Your Child's IFSP
Your IFSP is more than a piece of paper - it's a roadmap. Here's how to use it effectively:
- Set Meaningful Goals: Goals should be functional and relevant to your daily life. Instead of 'will point to 5 objects,' think 'will point to request a snack during mealtime.'
- Ask for Strategies: Don't just want to know what the therapist will do. Ask what you can do between sessions. Consistency is key.
- Track Progress: Keep your own notes on your child's development. This helps you see what's working and what needs adjusting.
- Build Relationships: Your service coordinator and therapists are your allies. Communicate openly and regularly.
Finding the Right Support: Beyond AzEIP
AzEIP is a fantastic starting point, but it may not meet every need. Some children require more intensive therapy than what Part C provides. This is especially true for ABA therapy, which can be highly effective for autism but is often delivered in higher doses.
If you're looking for additional support, you have options. You can contact your insurance company to find in-network ABA providers. You can also use a free matching service like Apply for ABA. We help connect families with vetted, BCBA-led providers in their area. It's a no-cost way to explore your options and find a provider that's the right fit for your family.
Remember, you are not alone on this journey. There are resources, professionals, and other parents ready to help. Taking the first step - reaching out for an evaluation - is the bravest and most important thing you can do for your child.
