Tennessee Part C Early Intervention: A Complete Guide for Parents

In short: Tennessee Part C (also called TEIS, the Tennessee Early Intervention System) provides free or low-cost developmental evaluations and early intervention services for children from birth to age three who have developmental delays or disabilities. If your child qualifies, you'll work with a team to create an Individualized Family Service Plan (IFSP) and receive services in your home or community. You can also access ABA therapy through private insurance or Medicaid, and a free matching service like Nearby ABA Therapy can help you find vetted, BCBA-led providers.
Key takeaways
- Tennessee Part C is known as TEIS (Tennessee Early Intervention System) and serves children from birth to age three.
- Eligibility is based on a documented developmental delay of 25% or more in one area, or a diagnosed condition with a high probability of delay.
- The first step is to call TEIS or complete an online referral; an evaluation is provided at no cost to families.
- If eligible, you'll receive an IFSP that outlines goals and services, delivered in natural environments like your home or childcare setting.
What Is Tennessee Part C?
Tennessee Part C is a federal program under the Individuals with Disabilities Education Act (IDEA) that provides early intervention services for infants and toddlers from birth to age three. In Tennessee, this program is administered by the Tennessee Department of Education and is known as the Tennessee Early Intervention System (TEIS). The goal is to help young children who have developmental delays or disabilities reach their full potential by supporting their growth and development during the critical early years.
Part C is not a single therapy but a comprehensive system that coordinates evaluations, service coordination, and a range of therapeutic services. These services are designed to be family-centered, meaning that parents and caregivers are active partners in creating and implementing a plan for their child.
Who Is Eligible for TEIS?
To qualify for TEIS, a child must be under three years old and meet at least one of the following criteria:
- A documented developmental delay of 25% or more in one or more areas, including cognitive, physical, communication, social or emotional, or adaptive development.
- A diagnosed physical or mental condition that has a high probability of resulting in a developmental delay, such as Down syndrome, cerebral palsy, or certain genetic disorders.
Autism spectrum disorder (ASD) is often a qualifying condition, especially if there are associated developmental delays. However, a formal ASD diagnosis is not always required if the child shows significant delays in communication or social skills.

How to Get Started with TEIS
If you suspect your child may have a developmental delay, the first step is to make a referral to TEIS. You can do this by calling the TEIS central intake line or by completing an online referral form through the Tennessee Department of Education website. You do not need a doctor's referral, and the process is free.
Once a referral is made, TEIS will assign a service coordinator who will guide you through the next steps. The service coordinator will schedule a comprehensive developmental evaluation, which is provided at no cost to your family. The evaluation typically involves a team of professionals who assess your child's skills in all five developmental areas.
What to Expect During the Evaluation
The evaluation is a positive, collaborative process. You will be asked about your child's history, daily routines, and any concerns you have. The evaluators will interact with your child through play-based activities to observe their abilities. This can take one to two hours, and you are encouraged to ask questions throughout.
After the evaluation, the team will determine if your child meets Tennessee's eligibility criteria. If they do, you will be invited to an IFSP meeting within 45 days of the referral (this is a federal requirement). If your child does not qualify, the team will provide recommendations for community resources and next steps.
Understanding Your Child's IFSP
An Individualized Family Service Plan (IFSP) is the cornerstone of Part C services. Unlike an IEP (Individualized Education Program) used in school-age special education, an IFSP focuses on the family as a whole. It outlines your child's strengths and needs, your family's concerns and priorities, and the specific outcomes you want to achieve.
The IFSP also lists the services your child will receive, such as speech therapy, occupational therapy, physical therapy, or developmental intervention. Services are provided in natural environments-places where your child typically spends time, like your home, a childcare center, or a community park. This helps your child learn in real-world settings.
Your Role as a Parent
You are an essential member of the IFSP team. Your input shapes the goals and strategies. You also have the right to approve or decline any service. The IFSP is reviewed at least every six months, and you can request a review at any time if your child's needs change.
Service coordination is a key part of the IFSP. Your service coordinator helps you access services, find providers, and transition to other programs when your child turns three.

How Part C Relates to ABA Therapy
Part C services are designed to address developmental delays broadly, but they may not include intensive behavioral interventions like Applied Behavior Analysis (ABA) therapy, which is the gold standard for autism treatment. ABA therapy focuses on teaching new skills and reducing challenging behaviors through positive reinforcement and data-driven strategies.
If your child has autism or is at risk for it, you may want to combine Part C services with ABA therapy. Many families find that ABA complements early intervention by providing structured, one-on-one support for communication, social skills, and daily living skills. ABA is typically covered by private insurance and Medicaid (TennCare) in Tennessee, so it is accessible to many families.
Finding ABA Providers
Navigating the world of ABA can be overwhelming. That's where Nearby ABA Therapy comes in. As a free matching service, we help families across Tennessee connect with vetted, BCBA-led ABA providers who are experienced in working with young children. We listen to your needs, verify credentials, and provide you with a shortlist of providers that match your location, insurance, and scheduling preferences. There is no cost to you-ever.
When you start ABA therapy, you can share your child's IFSP goals with the BCBA (Board Certified Behavior Analyst) to ensure that strategies are aligned. This collaborative approach maximizes your child's progress.
Costs and Insurance for Part C and ABA
TEIS services are provided at no cost to families for the evaluation and service coordination. However, some direct services may have a sliding-scale fee based on your income, but no family is denied services due to inability to pay. In many cases, TEIS will bill private insurance or TennCare for certain services, but you will never be responsible for out-of-pocket costs for Part C services.
ABA therapy, on the other hand, is typically covered by private health insurance plans, including those purchased through the marketplace, as well as TennCare (Tennessee's Medicaid program). The Affordable Care Act requires most plans to cover autism-related services, and Tennessee has specific mandates for ABA coverage. However, coverage details vary, so it's important to check with your insurance provider.
Using Your Insurance for ABA
When searching for an ABA provider, ask about their experience with your insurance plan. Many providers have a dedicated insurance team that can verify your benefits and handle prior authorizations. If you need help understanding your coverage, Nearby ABA Therapy can also provide guidance on what to ask your insurance company.

Transitioning Out of Part C at Age Three
As your child approaches their third birthday, TEIS will begin planning for the transition to preschool special education services. This is a critical time, and your service coordinator will help you navigate the process.
You will be introduced to your local school district's special education team, and your child may be evaluated for an IEP. If your child qualifies, they can receive services through the school system. If not, you may continue with private therapies, including ABA, funded by insurance.
Tips for a Smooth Transition
Start the transition process early-at least six months before your child turns three. Gather all your child's records, including the IFSP, evaluation reports, and progress notes. Attend the transition meetings and advocate for your child's needs. Remember, you are your child's best advocate.
If your child will continue ABA therapy after age three, ensure that the provider is aware of the transition and can adjust the treatment plan as needed. The BCBA will work with you to set new goals appropriate for the preschool years.
Practical Tips for Families
Here are some actionable tips to help you make the most of Tennessee Part C and ABA therapy:
- Act early: Don't wait to see if your child 'catches up.' Early intervention is most effective when started as soon as a concern is identified.
- Document everything: Keep a folder with your child's evaluation reports, IFSP, and any correspondence with TEIS and providers.
- Ask questions: You have the right to understand every aspect of your child's care. Don't hesitate to ask for clarification.
- Build a team: Share information between your TEIS service coordinator, therapists, and ABA provider to ensure consistency.
- Use your support network: Connect with other parents, join local support groups, and lean on family and friends.
Remember, you are not alone on this journey. Services like TEIS and ABA therapy exist to support your child and your family. And with free resources like Nearby ABA Therapy, finding the right help is easier than ever.
Common Mistakes to Avoid
Many parents make the mistake of waiting for a formal diagnosis before seeking help. With Part C, you don't need a diagnosis-a developmental delay is enough to qualify. Another common mistake is not attending IFSP meetings or not speaking up about your concerns. Your voice is vital.
Some families also assume that Part C services will be enough for a child with autism. While early intervention is beneficial, ABA therapy offers a different, more intensive approach that is specifically designed for autism. Combining both can be the best of both worlds.
Finally, don't overlook the importance of self-care. Raising a child with developmental needs is demanding. Take time for yourself, and accept help from others. A rested, supported parent is better able to advocate for their child.
