NC CDSA Early Intervention: How Birth-to-3 Services Work and When to Add ABA

The NC CDSA, or Children's Developmental Services Agency, is the doorway to early intervention for North Carolina children from birth to age 3. 

Anyone can make a referral, evaluations come at no cost to families, and an eligible child's family plan is due within 45 days. ABA therapy is a separate service with its own diagnosis and insurance rules, so the best timing depends on where your child is today. 

At Blue Jay ABA, we work alongside early intervention teams and can help you decide when ABA belongs in the plan.

What the NC CDSA Does and Who It Serves

The NC CDSA is the local office that runs the North Carolina Infant-Toddler Program, the state's early intervention system for children from birth to age 3 who have developmental delays or disabilities. The program is voluntary, and families set the pace.

North Carolina's Infant-Toddler Program

Early intervention comes from Part C of the federal Individuals with Disabilities Education Act. In North Carolina, 16 CDSAs serve all 100 counties, so every family has a local starting point. A child can stay in the program until the family plan's goals are met, until the child is found ineligible, or until the third birthday.

Services a CDSA can coordinate

According to NC Department of Health and Human Services, the program offers:

• Speech-language therapy, occupational therapy, and physical therapy
• Special instruction
• Family training, counseling, and home visits
• Assistive technology
• Psychological, nutrition, vision, audiology, and nursing services
• Respite, transportation, and service coordination

Notice what the list leaves out: ABA therapy by name. Early intervention can address communication, play, and daily routines, while ABA for autism is usually arranged separately through insurance after a diagnosis.

What early intervention costs

Evaluation and service coordination are at no cost to the family. Other services use a sliding fee scale, and Medicaid and other insurance are billed with your permission. NC DHHS states that a family unable to pay will not be denied needed services.

Signs It May Be Time to Call Your NC CDSA

You do not have to wait for a specialist to confirm a worry before you call. CDC recommends that parents track milestones and speak up early, and the American Academy of Pediatrics advises developmental screening at 9, 18, and 30 months, with autism-specific screening at 18 and 24 months. C

DC surveillance data estimates that about 1 in 31 eight-year-olds has been identified with autism, which is one reason early screening gets so much attention.

Early concerns families bring to us

Parents describe worries like these:

• Few sounds, gestures, or words for their child's age
• Little back-and-forth play or shared attention
• Limited response when called by name
• Loss of skills the child once had
• Very strong distress with routine changes or everyday sensory input

None of these confirms autism. They are reasons to ask for an evaluation. If speech is your main worry, our post on how clinicians separate speech delay from autism can help you describe what you see.

You can make the referral yourself

Anyone, including parents, can refer a child by phone, email, fax, letter, or in person at the local CDSA. You will share the child's name, date of birth, address, phone number, a parent's name, and the reason for your concern. Parental consent is not required to make a referral, though your consent is needed before your child is evaluated.

How the NC CDSA Process Works, Step by Step

The process is built around a 45-day timeline from referral to a written plan. Knowing the order of events helps you prepare questions and keep records.

The seven steps at a glance

1. Referral. You or someone you trust contacts your local CDSA.
2. Service coordinator assigned. Your coordinator contacts you, explains your rights, and asks for consent to evaluate.
3. Evaluation. The team reviews records, interviews you, observes your child, and uses developmental tools, often in your home or child care setting.
4. Eligibility decision. Only the CDSA determines eligibility.
5. IFSP meeting. The Individualized Family Service Plan is developed within 45 days of referral, unless a family postpones.
6. Services begin. Services should start no later than 30 days after the plan is signed.
7. Reviews. The plan is reviewed at least every six months, and you can ask for a review sooner.

You can go at your own pace, pause eligibility determination, or withdraw at any time.

Who qualifies

A child can qualify in two ways. The first is a developmental delay, meaning the child is considerably behind same-age peers in thinking and learning, physical development, communication, social-emotional development, or adaptive skills such as feeding and dressing. The second is an established condition, meaning a diagnosed condition with a high probability of delay. State materials list autism among the examples.

Existing records can sometimes establish eligibility without a new evaluation. If your child already has a diagnosis, ask your service coordinator whether those records can be used.

What a family-centered plan looks like

The IFSP is a written plan built around your priorities and your daily routines. When families share these plans with us, the strongest ones state outcomes in everyday language, such as asking for a snack with a sound or sign at mealtime. Goals like that carry over smoothly into ABA programming later.

Does the NC CDSA Diagnose Autism? What You Need Before ABA Starts

A CDSA eligibility evaluation and an autism diagnosis answer different questions. Medicaid-funded ABA requires the second one, so it helps to know how the two connect.

Eligibility versus diagnosis

The CDSA decides whether your child qualifies for early intervention. An autism diagnosis comes from a formal developmental evaluation by trained specialists such as a developmental pediatrician or child psychologist, using developmental history and observed behavior. CDC notes that a diagnosis by an experienced professional can be considered reliable by age 2.

If you are ready for that step, our autism evaluation team can talk through options. If your child was just diagnosed, our list of newly diagnosed questions can help you plan your next conversations.

What NC Medicaid asks for before ABA

According to NC Medicaid's latest provider bulletin, ABA through Medicaid requires:

• An ASD diagnosis from a licensed qualified provider using clinically appropriate, validated tools
• A behavioral, adaptive, or functional assessment
• An individualized treatment plan approved in advance

A provisional diagnosis is acceptable for children younger than 3, and a final diagnosis must follow within six months to keep eligibility. Our ABA assessment is where that treatment plan begins, and our post on the first ABA assessment explains how to prepare.

When to Add ABA to Early Intervention

No single age or milestone tells you the time has come. Based on what we see, a handful of signals point toward adding ABA, and your CDSA team stays involved either way.

Signals that ABA may be worth adding

• A diagnosis, or a provisional diagnosis for a child under 3, is in hand
• Communication or play goals need more daily practice than weekly sessions allow
• Behavior such as hitting, running off, or intense tantrums disrupts meals, sleep, outings, or safety
• You want hands-on coaching you can use across routines
• Your child is approaching age 3 and you want continuity through the preschool transition

How ABA and CDSA services fit together

Your child can continue CDSA services while ABA begins. The teams work best when they share goals, so bring the IFSP to your ABA assessment. NC Medicaid also directs providers to consider every service a child receives, including speech and occupational therapy, when setting ABA hours.

If you are weighing therapies, our comparison of speech therapy and ABA explains where they differ and where they overlap. Scheduling matters too. I usually suggest spreading toddler sessions across the week instead of stacking them on one day.

What early ABA looks like for toddlers

For toddlers, ABA looks like play. Sessions use favorite toys, songs, and routines to teach requesting, imitation, turn-taking, and tolerating small changes. CDC describes the Early Start Denver Model, a play-based approach built on ABA principles for children 12 to 48 months, and NC Medicaid lists it among covered treatment models.

Read more about ABA for 2-year-olds. Many toddlers start with home-based ABA, where skills are practiced in the spaces your child knows best. Parents are part of every session through ABA parent training.

How many hours a toddler needs

There is no formula. NC Medicaid requires hours to be individualized, medically necessary, and no greater than the child's needs. A provider who quotes the same hours for every toddler is a flag worth questioning.

Planning the Move From the CDSA to Preschool at Age 3

Every child leaves the Infant-Toddler Program at age 3, which makes the second half of your child's third year a natural moment to review ABA and school services together.

What the transition involves

Your service coordinator begins transition planning early and writes a transition plan into the IFSP. With your consent, the CDSA can notify your local school system between nine months and 90 days before your child's third birthday, and the school team evaluates for preschool services under Part B of IDEA through an Individualized Education Program.

Keeping ABA going after age 3

Insurance-funded ABA can continue through the transition. NC Medicaid does not cover services that duplicate what a child receives through an IEP, so we help families map out which goals belong in which setting. School-based ABA therapy can support your child in preschool when the school and family agree it fits.

How Blue Jay ABA Supports Families Leaving Early Intervention

Families come to us from CDSAs across the state, and our in-home teams meet toddlers in familiar spaces. We work with families in Durham, Cary, Winston-Salem, Concord, Greenville, and Rocky Mount, along with many other North Carolina communities.

Consider a boy just past his second birthday whose CDSA team had been providing weekly speech therapy and special instruction. After his diagnosis, his family added ABA. 

The first goals were small: handing us a picture to request a snack, tolerating a short wait, and joining a simple song routine. His mother's most useful tool was the IFSP she shared with us, because it showed which words and routines his therapists had already worked on.

Progress varies from child to child, and we never promise a particular outcome. What we promise is a plan built from your child's strengths and your family's priorities.

We also verify benefits and manage authorization for NC Medicaid and BlueCross BlueShield families.

Putting Your NC CDSA Plan and ABA Timing Together

The NC CDSA gives your family a free, local starting point, and ABA therapy can follow when your child's diagnosis, goals, and daily needs call for it. In my experience, the families who feel least rushed are the ones who start early intervention first and add ABA with a clear reason.

If you are unsure where your child fits, reach out to Blue Jay ABA. We will listen, review your child's records, and help you decide on the next step at a pace that suits your family.

Frequently Asked Questions About the NC CDSA and ABA

Parents ask us these questions in nearly every first call.

Do I need a doctor's referral to contact the NC CDSA?

No. Anyone, including parents, can refer a child by phone, email, fax, letter, or in person. Your consent is required before your child is evaluated.

How much does NC CDSA early intervention cost?

Evaluation and service coordination are free. Other services follow a sliding fee scale, Medicaid and insurance are billed with your permission, and a family unable to pay will not be denied services.

Can my child get ABA and CDSA services at the same time?

Often yes. ABA is arranged through insurance after a diagnosis, and the teams should coordinate goals. Medicaid considers every service your child receives when setting ABA hours.

Does the CDSA diagnose autism?

The CDSA determines eligibility for early intervention. An autism diagnosis comes from a qualified specialist. Medicaid ABA requires a diagnosis, and a provisional one is acceptable under age 3 if finalized within six months.

What happens when my child turns 3?

Early intervention ends at age 3. Your service coordinator builds a transition plan, the school system evaluates for preschool services, and insurance-funded ABA can continue alongside school supports.
