The first week of in-home ABA in Union County

Practical steps for starting in-home ABA in Union County, NJ: access points, insurance, choosing a provider, and what to expect in week one.

Published October 3, 2026 · Union County, New Jersey

Start with the right access point for your child's age

The first thing to sort out is which system you are dealing with. For a child under 3, the New Jersey Early Intervention System is the single entry point. You do not need a doctor's referral to call them, but they will ask about your concerns and set up an evaluation. For a child age 3 through 21, the Children's System of Care uses PerformCare as the single access point. Call PerformCare to request behavioral health services, including ABA. They will ask about your child's needs and your insurance, then help connect you to providers in Union County.

If your child is covered by NJ FamilyCare (the state's Medicaid and CHIP program), you are already in the system. Your managed care plan, whether it is Horizon NJ Health, Wellpoint, Aetna Better Health of NJ, or UnitedHealthcare Community Plan, must provide ABA coverage. But even with private insurance, the same access points apply for children under 21.

After age 21, the Division of Developmental Disabilities takes over. That is a different process, and not relevant for the first week of ABA in childhood, but know it exists.

Get your insurance authorization moving

You will need a prescription or referral for ABA from a doctor (a pediatrician, psychiatrist, or developmental pediatrician). The provider you choose will typically handle the prior authorization with your insurance, but you should call your insurance company yourself to confirm that ABA is a covered benefit and ask what the authorization process requires. Do not assume anything. Ask for the name of a case manager or behavioral health coordinator and write it down.

Do not expect a fixed timeline. Authorization can take days or weeks, depending on the plan and the completeness of the paperwork. The provider's intake coordinator is the right person to ask about the expected process for your specific insurance. They have done this before with Union County families.

Choosing a provider in Union County

Union County has 52 ABA providers registered on the federal NPPES registry. That is a lot of options. You do not have to pick the one closest to you, but you likely have a short drive. Of the 21 municipalities, 17 have at least one provider registered in the town itself, and every town has a provider within 7 miles.

The towns with the most providers are Union (9), Cranford (7), Clark (6), Westfield (6), Elizabeth (4), and Linden (4). If you live in one of those towns, you may have several within walking distance or a few minutes' drive. In smaller towns like Garwood, Kenilworth, or Mountainside, you will still be within 7 miles of a provider.

When you call a provider, ask directly: do you provide in-home ABA in my town? How quickly can you start an assessment? Who will be the BCBA (Board Certified Behavior Analyst) overseeing the program? How many hours per week do you typically recommend? And what does your intake process look like? Be honest with them about your child's age, diagnosis, and any other services they receive.

What actually happens in the first week

The first week of in-home ABA is not therapy in the way you might imagine. It is mostly assessment and relationship building. The BCBA will come to your home, observe your child, ask you a lot of questions, and take data. They may bring a tablet or paper data sheets. They will look at your child's communication, play, daily living skills, and behavior. They will also ask about your family's routines and what you hope ABA will change.

You might see a Registered Behavior Technician (RBT) in the first week as well, but often they come later, after the BCBA has written a treatment plan. The BCBA will teach you how to pair with your child, how to run simple programs, and how to collect data yourself. You are not a passive observer. You will be a co-therapist.

Do not be surprised if the first week feels slow or unstructured. The BCBA needs to learn what your child likes, what they are afraid of, and what triggers problem behavior. This baseline is the foundation for everything else. Ask to see the data they are collecting and the goals they are considering.

Your role as the parent in Union County

The BCBA will rely on you as the expert on your child. Be clear about what is working at home and what is not. Share information about your child's school district, especially if they are in one of the districts listed here such as Berkeley Heights, Clark, Cranford, Elizabeth, Garwood, Hillside, Kenilworth, Linden, Mountainside, or Plainfield. With your written consent, the BCBA can coordinate with the school to keep strategies consistent, but you have to start that conversation.

Ask your BCBA how they communicate with the school. Some will write a summary, others will attend IEP meetings. You do not need to have that figured out in the first week, but you should mention the school connection early so the BCBA has it on their radar.

Practical tips for week one

Make a call list before you start. Write down the names and numbers of the BCBA, the agency's intake coordinator, your insurance case manager, and your PerformCare contact (if applicable). Put them on the fridge.

Ask about the scheduling. In-home ABA often happens in the afternoon or evening, depending on the RBT. You will need to be home during sessions. Be clear about your own schedule and any other children in the house. The provider may have specific policies about pets, cameras, and who else can be present.

If you hit a snag in the first week, such as a cancelled session or a billing question, do not wait. Call the agency's office, not just the BCBA. And if the snag is about authorization, you can call PerformCare or your insurance directly. You are allowed to do that.

Finally, know that the first week is about building a plan that fits your family, not about immediate results. There is no standard for how many hours of ABA a child should get; that is determined by assessment, not by a formula. In Union County you have plenty of providers to choose from, so if one does not feel like a good fit, you can look at another. You are not locked in.
