From CDSA Early Intervention to ABA: What Happens When Your Child Turns 3 in NC

Introduction

Most parents find out about this deadline by accident.

You have been working with a CDSA service coordinator since your child was eighteen months old. Speech is going well. The developmental specialist comes to your house. You have a rhythm. Then, somewhere around your child's second birthday, someone mentions a "transition meeting," and you learn that all of this ends on the third birthday.

Not tapers. Ends.

In North Carolina, all children must transition out of the Infant-Toddler Program by age three. There is no extension, no grace period, and no automatic replacement. What comes next depends entirely on decisions that get made in the months before that birthday, which is why this article exists. If your child is between two and three years old, you are already inside the window that matters. 

This guide walks through the real transition timeline, what the school system does and does not provide, and where ABA therapy fits into the gap that most families do not see coming until they are already standing in it.

Why Your Child's Third Birthday Is a Hard Deadline in North Carolina

The abruptness catches people off guard because nothing else in early childhood works this way. The reason is structural: your child is not moving to a different program within the same system. Your child is moving to a different system entirely.

Who Runs Early Intervention Before Age 3

Early intervention for children from birth to three is delivered under Part C of the Individuals with Disabilities Education Act. In North Carolina, that program is the NC Infant-Toddler Program, administered by the Department of Health and Human Services and delivered locally through Children's Developmental Services Agencies, better known as CDSAs.

Your CDSA assigned you an Early Intervention Service Coordinator, or EISC. Together you built an Individualized Family Service Plan, the IFSP. CDSA services typically include evaluations and assessments, service coordination, special instruction, physical, occupational, and speech-language therapies, and assistive technology, delivered in family homes and childcare settings around everyday routines. 

Notice what is not on that list. Early intervention in North Carolina does not provide comprehensive ABA therapy. Some families arrive at age three having never had an ABA provider at all, which makes the next step feel like starting from zero.

What Changes on the Third Birthday

On the third birthday of a child with a disability in North Carolina, responsibility for services shifts from the Department of Health and Human Services, which runs the Part C program, to the Department of Public Instruction, which runs the Part B program. Locally, the lead agency responsibility shifts from the CDSA to the Public School Unit, also known as the Local Educational Agency. 

So three things change at once: the agency, the funding source, and the legal framework. The IFSP, a family-centered plan built around your household, is replaced by an Individualized Education Program, a school-centered plan built around educational access. Different people, different building, different goals, different paperwork.

That is a lot of change to absorb in one day, and it is why the planning process starts so early.

The NC Early Intervention Transition Timeline, Step by Step

Here is what the law actually requires and roughly when it happens. Put these on your calendar now.

Around Age 2 Years, 3 Months: Transition Planning Begins

As your child nears two years and three months of age, your Early Intervention Service Coordinator will help you determine next steps. This is the first real conversation, and it is where the transition plan gets added to your IFSP. Your EISC will explain the notification process and what programs might be available after three. 

This is also the moment to say out loud that you are considering private ABA. Coordinators are not always the ones to raise it, because it sits outside the systems they administer.

Nine Months to 90 Days Before: The Transition Planning Conference

This is the anchor event. As early as nine months before the third birthday, but no later than 90 days before it, a transition planning conference is held with you, your EISC, your current service providers, and others you request. If your child is potentially eligible for special education and related services in the Part B preschool program, a representative from the Public School Unit is invited with your permission. 

The purpose is to discuss services your child may be eligible to receive under Part B, review program options from the third birthday through the remainder of the school year, and update the transition plan, including the steps for exiting Part C.

Two practical notes. First, 90 days is the latest this can happen, not the target. Push for the earlier end of that window, because everything downstream depends on it. Second, if your child has a vision or hearing concern, or complicated or intense service delivery needs, the PSU may be notified, and a preliminary face-to-face meeting may occur as much as twelve months before the third birthday. 

Before the Third Birthday: Evaluation and the IEP

After the conference, the PSU conducts its own eligibility determination. Part C eligibility does not carry over. Your child is evaluated again, under different criteria, by a different team.

If your child is found eligible, an IEP must be in place by the third birthday. If your child is found not eligible for preschool special education, services stop on the birthday, and nothing replaces them. 

That second outcome is more common than parents expect, and it is the single strongest argument for having a private ABA plan in motion well before the determination comes back.

IFSP vs. IEP: What Actually Changes for Your Family

There is a meaningful difference between how a child's needs are addressed by a CDSA, which operates on a developmental model, and by a school district, which operates on an educational model.

That single distinction explains almost every surprise families run into during their first post-birthday year.

The Service Gap Most Families Do Not See Coming

Part B Preschool Services Are Educational, Not Medical

Preschool special education is designed to give a child access to education. It is not designed to deliver medically necessary autism treatment, and it is not measured that way.

In practice, that often means a child moves from several hours a week of one-to-one, home-based early intervention to a preschool classroom placement of a few hours per day, with speech and occupational therapy delivered in short pull-out or push-in blocks and shared across a caseload. The classroom may be excellent. It is still a different intervention with a different purpose.

A preschool IEP also stops for the summer unless extended school year services are specifically written in and approved. Autistic children who are sensitive to routine disruption frequently lose ground across a ten-week gap, and families are often the first to notice it before the school does.

What Families Notice in the First Months After Turning 3

In our intake conversations, the pattern repeats almost word for word. Parents tell us the classroom is fine, the teacher is kind, and something is still missing. Usually it is one of these:

• The behaviors that were emerging at two, including elopement, aggression during transitions, or intense restricted interests, are now being managed in the classroom rather than systematically taught around.
  
  
• Communication goals got broader and less frequent. Twice-weekly speech is not the same as embedded communication instruction across the day.
  
  
• Nothing addresses home. Bedtime, mealtimes, toileting, and sibling conflict do not appear on an IEP because they are not educational access issues.
  
  
• There is no parent training component. The IFSP was built around coaching you. The IEP is built around teaching your child at school.

None of that is a criticism of the school system. It is a description of scope. Part B was never designed to carry the clinical load, and expecting it to is how families lose a year.

Where ABA Therapy Fits After Age 3

ABA is delivered as a medical service, authorized through health insurance or Medicaid based on medical necessity, and it runs on its own schedule independent of the school calendar. It can sit alongside an IEP rather than instead of one, and in our experience the strongest outcomes come from families who run both.

In-Home ABA

In-home ABA therapy is the most natural continuation of what CDSA services looked like, which makes it the easiest transition for a three-year-old. Skills get taught where they are actually used: at the dinner table, in the bathroom, during the hand-off at the door. For families coming off a home-based IFSP, this is usually where we start.

Center-Based ABA

Center-based ABA offers a structured environment with consistent staffing and built-in peer opportunities. For a child who will be entering a preschool classroom for the first time, a center setting can be a useful rehearsal space for group routines, waiting, and transitions.

School-Based ABA

School-based ABA therapy puts behavioral support directly into the environment where the IEP is being implemented, and keeps the clinical team and the educational team looking at the same data. This coordination matters most during the first semester after the transition.

Parent Training

ABA parent training is the piece that most directly replaces what you lose when the IFSP closes. The IFSP was a family plan. Parent training keeps a family plan in place, and it is the component families consistently tell us they underestimated going in.

If your child is still under three, early intervention ABA therapy can begin before the birthday, which means the transition changes your child's school situation without disrupting the clinical work.

Paying for ABA in North Carolina: Insurance and Medicaid Basics

This section is the reason to start early. Coverage questions take weeks, not days.

Private and Employer Health Plans

North Carolina's autism insurance law, enacted as Session Law 2015-271, requires health benefit plans to cover screening, diagnosis, and treatment of autism spectrum disorder, including adaptive behavior treatment, when a licensed physician or licensed psychologist determines the care to be medically necessary. Coverage for adaptive behavior treatment may be capped at $40,000 per year and limited to individuals 18 and younger, with the dollar amount indexed annually to the Consumer Price Index for the South Region. Importantly, coverage may not be denied on the grounds that the treatment is habilitative or educational in nature. 

The catch is which plans the law reaches. The state law applies to fully insured large group plans, grandfathered individual plans, and grandfathered small group plans. Self-funded employer plans are governed by federal law instead, so the answer depends on your specific plan documents rather than on the state mandate. 

NC Medicaid Coverage

NC Medicaid covers ABA under Clinical Coverage Policy 8F, Research-Based Behavioral Health Treatment. The RB-BHT benefit covers a range of autism treatment models, including but not limited to Applied Behavior Analysis. Services are delivered under a prior authorized treatment plan with measurable goals, developed by a Licensed Qualified Autism Service Provider and reviewed at least every six months, and prior approval is required. 

Note that NC Medicaid published an updated version of CCP 8F effective August 1, 2026, which added certification requirements for paraprofessionals providing RB-BHT services and removed telehealth for paraprofessional services. If you are comparing providers, it is fair to ask how they have adjusted to the current policy. 

One more detail worth knowing: for a child under three at the time services begin, a provisional autism diagnosis is accepted, with a confirmed diagnosis expected within six months. A diagnosis still in process is not automatically a barrier to getting started. 

Your Pre-Birthday Action Plan

Work backward from the birthday, not forward from today.

Twelve to Nine Months Before (Roughly Age 2 to 2 Years 3 Months)

Tell your EISC you want ABA considered as part of the transition plan. Ask when your transition planning conference will be scheduled and request the earlier end of the window. If your child does not yet have a formal autism diagnosis, start that evaluation now, because diagnostic waitlists are frequently the longest wait in the entire sequence.

Six Months Before

Call the member services number on your insurance card and ask three specific questions: is adaptive behavior treatment or ABA a covered benefit, is the plan fully insured or self-funded, and what is the prior authorization process? Write down names and reference numbers. Begin contacting ABA providers and ask directly about current waitlist length for a three-year-old.

Three Months Before

Your transition planning conference should have happened by now. Consent to the PSU evaluations. Submit your ABA authorization paperwork, including the diagnostic report and any prescription or referral your plan requires. Ask each provider you are considering for a realistic start date rather than a place on a list.

The Month Of

Confirm the IEP is written and will be in effect on the birthday. Confirm your ABA authorization status in writing. Ask your CDSA team to share records with both the PSU and your ABA provider, which requires your written consent.

We have seen families complete this whole sequence with no gap at all, and we have seen families start in month eleven and lose most of a year to authorization timelines and waitlists. The difference is almost never the child's needs. It is the calendar.

Questions to Ask at Your Transition Planning Conference

Bring these written down:

1. What is the specific date the PSU evaluation will be completed?
   
   
2. If my child is found eligible, what placement and service hours are you anticipating, and how does that compare to current IFSP hours?
   
   
3. Will extended school year services be considered at the initial IEP meeting?
   
   
4. Who is my point of contact at the PSU after the CDSA file closes?
   
   
5. How will the school team coordinate with an outside ABA provider?
   
   
6. What happens on the birthday if the IEP is not finalized in time?

Ask question six even if everyone seems confident. It is the one that surfaces problems early.

Conclusion

The third birthday is not a cliff because anyone designed it to be one. It is a cliff because two separate systems hand off to each other on a single date, and only one of them is responsible for what happens next.

What you can control is the runway. The transition planning conference has to happen between nine months and 90 days before the birthday. Eligibility for Part B is determined separately from Part C, and a finding of ineligibility ends services entirely. Preschool special education, where it does apply, is educational in purpose and school-bound in schedule, which leaves the medically necessary behavioral work unaddressed. And insurance verification, prior authorization, and provider waitlists all run on timelines measured in months.

Start the ABA conversation at the same time you start the school conversation, not after it. Families who do that walk into the birthday with a plan on both sides. Families who wait find out in week three of preschool that the plan only covered half of it.

Frequently Asked Questions

What happens when CDSA services end at age 3 in North Carolina?

All children exit the NC Infant-Toddler Program by their third birthday. Responsibility shifts from the CDSA to your local Public School Unit under IDEA Part B. If your child is found eligible for preschool special education, an IEP replaces the IFSP and must be in effect on the third birthday. If your child is found ineligible, Part C services simply end with no replacement, which is why many families arrange private ABA therapy in advance.

When does the transition planning conference have to happen in NC?

It must be held no later than 90 days before your child's third birthday, and it can be held as early as nine months before. If your child has vision or hearing concerns or complex service needs, an initial meeting with the Public School Unit may occur as much as twelve months in advance. Because the 90-day mark is a deadline rather than a goal, most families are better served requesting the conference toward the earlier end of the window.

Can my child receive ABA therapy and preschool special education at the same time?

Yes. They are separate systems with separate funding. An IEP is an educational plan delivered by the school under IDEA Part B, while ABA is a medical service authorized through private insurance or NC Medicaid based on medical necessity. Many families run both, using school-based or in-home ABA to address skills that fall outside the scope of an educational plan, including home routines, communication across settings, and parent training.
