What Does an ABA Therapist Do During a Therapy Session?
Someone from an ABA agency is coming to your house next week. You signed the paperwork, you were told your child will be working with an ABA therapist, and nobody explained what that person is actually going to do for two hours at your kitchen table.
Wanting that answered before it happens is reasonable. Here’s the role in plain terms, who oversees it, and what you should ask.
An ABA therapist delivers one-on-one therapy to your child using a plan written by a Board Certified Behavior Analyst, or BCBA. Most ABA therapists are Registered Behavior Technicians, or RBTs. They teach skills in small steps, record data on what your child does, and report back to the BCBA, who changes the plan based on what the data shows.
An in-home session usually runs two to three hours, and the shape of it is more ordinary than most parents expect.
The first stretch has no demands in it. Your RBT sits on the floor and plays with whatever your child is already interested in. This is called pairing, and it isn’t filler. A child who associates the person at the door with being asked to do hard things will avoid the door. So, the first several minutes, and sometimes the first several sessions, are spent becoming someone worth being around.
Then the work starts, though it rarely looks like work from the outside. Your BCBA has written a set of targets. Maybe it’s requesting a snack instead of reaching for it. Maybe it’s tolerating a hand on the shoulder during transitions. The RBT weaves those targets into play and into whatever is already happening in your house.
Getting shoes on before the bus is a transition target. Snack time is a requesting target. A good session uses your actual routines instead of running drills at a table, because the skill has to work in the room where your child needs it.
Throughout the session, the RBT records data: every trial, every prompt level, and every response. It can look like someone glancing at a phone or clipboard more often than you would expect, but that recordkeeping is what makes the rest of the work accountable.
At the end, you get a handoff: what went well, what didn’t, and what to keep doing until the next session. If you’re not getting that handoff, ask for it.
ABA Therapist vs. BCBA: What’s the Difference?
“ABA therapist” is a job title. It isn’t a credential, and no board issues it. The credential underneath it is usually RBT. This matters because two agencies can both advertise ABA therapists and mean different things.
The short version: the BCBA decides what gets taught, and the RBT teaches it.
If you’re comparing providers, ask which credential the person in your home holds. Some agencies use uncertified behavior technicians, which is legal in some settings and not the same thing.
A BCBA completes the assessment, develops the treatment plan, and determines the recommended number of therapy hours based on your child’s individual goals and needs. Learn more about how individualized ABA therapy plans help children build lasting skills.
How Is an ABA Therapist Supervised?
This is the question most parents don’t think to ask, and it’s the one that tells you the most about a provider.
An RBT never works alone in the sense that matters. The Behavior Analyst Certification Board requires every practicing RBT to receive supervision covering at least 5% of the hours they spend delivering services each calendar month.
An RBT working 80 service hours in a month needs at least four hours of supervision that month.
There must be at least two real-time, face-to-face supervision contacts, at least one of them individual. The supervising BCBA must directly observe the RBT working with a client during at least one monthly meeting. Phone calls and emails do not count.
In practice, that means your BCBA turns up during sessions. Not to check on your child, but to watch how the plan is being run and change it when it isn’t working. On your statement, this may appear as a separate line from the direct therapy hours because supervision and protocol modification are billed differently from one-on-one sessions.
If a provider can’t tell you who the supervising BCBA is or how often that person will be in your home, that’s worth pressing on.
Questions to Ask Before ABA Therapy Begins
Bring these questions to the consultation. Any provider worth hiring will answer them without getting defensive.
Is the person coming to my home a certified RBT, and can I look them up on the BACB registry?
Who is the supervising BCBA, and how often will they be here in person?
Has this person had a background check, and what does your screening cover?
Will my child have the same RBT each week? What happens when that person is sick or leaves?
How will I know what happened in a session I wasn’t in the room for?
What do you do when my child says no or shows me they’re done?
Ask that last question specifically. You want to hear about stopping, offering a break, and adjusting the demand, not about pushing through.
That question can tell you a great deal about a provider. A plan your child fights every week is unlikely to produce much, and a good BCBA already knows it.
In-Home ABA Therapy at Seed & Grow ABA
We deliver in-home ABA therapy in New Jersey. A BCBA assesses your child, writes the plan, and supervises the RBT who provides direct therapy. You meet both.
Parent training is part of every plan, not something we sell separately. A skill that only shows up during a session isn’t really a skill yet. Your BCBA teaches you the same strategies your RBT is using, so they can hold up at bedtime and at your mother-in-law’s house.
Before anything begins, we check your benefits and give you your expected costs in writing. If we’re out of network with your plan, we tell you. Read our guide to ABA therapy insurance coverage in New Jersey, or learn whether ABA therapy may be a helpful next step for your child.
Frequently Asked Questions
Is an ABA therapist the same as a BCBA?
No. An ABA therapist is usually a Registered Behavior Technician who provides direct one-on-one therapy. A BCBA holds a master’s degree, assesses your child, writes the treatment plan, and supervises the RBT. Both are involved in your child’s care, but they have different roles.
Do I need to stay in the room during sessions?
Not the whole time. It depends on the goals. Some targets need you there, especially those involving family routines or parent training. Others may go better when your child is not splitting attention. Your BCBA will explain which is which, and you are always welcome to observe.
What if my child doesn’t connect with their ABA therapist?
Say so early. The fit between a child and an RBT is real, and it affects progress. A provider should take that seriously and consider reassigning the therapist rather than simply telling you to give it more time.
How many hours each week will an ABA therapist work with my
child?
It depends on your child’s assessment and what your plan authorizes. Focused programs generally run 10 to 15 hours a week and target a specific set of skills. Comprehensive programs generally run 25 to 40 hours. Your BCBA recommends a range based on the assessment, and your insurance authorization confirms what is approved.
