ABA Therapy · Hours & Duration

How long does ABA therapy
actually take?

Most children attend ABA 10–40 hours a week for 1–3 years. The right answer depends on your child’s age, goals, and what insurance authorizes. Here’s how we figure it out together — with no waitlist.

Comprehensive vs. Focused

Two kinds of ABA, two very different schedules.

ABA isn’t one-size-fits-all. Most insurance plans authorize one of two formats — and the hours-per-week number you’ll hear depends on which one your child needs.

Comprehensive ABA

25–40 hours a week

For younger children (usually under 6) and families addressing a broad set of skills — communication, play, daily living, social, and behavior — all at once. Built around the early-intervention window when learning is fastest.

  • 5 days per week, center-based or in-home
  • 1:1 with a Registered Behavior Technician (RBT)
  • BCBA supervision and parent training built in
  • Best fit for ages 2–6
Focused ABA

10–25 hours a week

For older kids, school-age learners, or anyone with a narrower goal list — like reducing a specific behavior, building a particular life skill, or supplementing what school already provides.

  • 2–5 sessions per week, often after school
  • Targeted: potty training, social skills, feeding, communication
  • Great for ages 6–18 or graduates of comprehensive ABA
  • Often runs in parallel with school and OT/SLP

The number of hours isn’t arbitrary. It’s based on the BCBA’s assessment, the goals your family wants to reach, and the dosage research supports for that age and skill set. We never push for more hours than your child needs — and we adjust the plan as your child progresses.

The honest timeline

Most families are with us for 1 to 3 years.

ABA is a marathon, not a sprint — but it has a finish line. Here’s what the journey usually looks like, broken into the phases your family will actually feel.

1

Weeks 1–4

Building rapport

Your child meets their RBT and BCBA. Early sessions are mostly play — we’re learning what motivates your child and pairing the center (or therapist) with good things. Real teaching starts when your child is happy to be there.

2

Months 2–6

Skill acquisition

The bulk of new learning happens here. Families typically see first words, first independent requests, first toilet successes, fewer meltdowns. We hold a 6-month review with you, the BCBA, and your insurance.

3

Months 6–24

Generalization

Skills move from the therapy room into real life — home, the grocery store, the playground, school. Hours often start to step down here as your child takes on more independence.

4

Year 2–3

Transition & discharge

Once goals are met or your child is school-ready, we plan a structured fade-out. Some families graduate fully; others move from comprehensive to focused ABA for ongoing support. Either way, discharge is the goal.

How the hours get set

The number isn’t a guess. Here’s the process.

Before a single therapy session, your BCBA spends several hours assessing your child and writing a treatment plan. That plan is what your insurance reviews — and what tells us how many hours per week to recommend.

See our full intake process
  1. A

    Initial assessment (4–8 hours over 1–2 weeks)

    Your BCBA uses tools like the VB-MAPP, ABLLS-R, or AFLS — depending on age — to map your child’s current skills against age-typical milestones. We also interview you about what matters most at home.

  2. B

    Treatment plan written with you

    The BCBA drafts 8–15 measurable goals across communication, social, daily living, play, and behavior reduction. You approve them. Nothing gets worked on that you didn’t sign off on.

  3. C

    Insurance authorizes a specific number of hours

    We submit the plan; the insurer authorizes a weekly hour count — usually 6 months at a time. Most authorizations fall in the 15–30 hour range for school-age kids and 25–40 hours for younger ones.

  4. D

    We adjust as your child progresses

    Every 6 months we re-assess, share data with you, and recommend stepping hours up, down, or holding steady. The plan flexes — your child’s real progress drives it, not a calendar.

What “progress” actually looks like

You’ll see data, not just vibes.

Every goal in your child’s plan has a measurable definition and a way to track it. That’s the “A” in ABA — Applied. You’ll see exactly what’s improving, what’s plateaued, and what we’re changing.

Session data, every visit

RBTs log frequency, duration, and accuracy on each goal during every session — not at the end of the month, not from memory. The BCBA reviews it weekly.

Monthly parent meeting

You meet with the BCBA once a month to review graphs, watch a session if you’d like, and decide what to push on next. No surprises at the 6-month mark.

Mastery criteria, not opinions

A goal is “mastered” when your child performs it independently across 3 sessions, with 2 different people, in 2 different settings. Then we move on — or fade hours.

Parent training built in

A few hours each month are reserved for coaching you — because gains don’t generalize if home looks completely different from the therapy room.

6-month re-assessment

The same assessment from intake gets re-run at 6 months. Now you can see the same scoresheet, side by side — what shifted, what didn’t, what’s next.

Discharge is the goal

We don’t keep families in ABA forever. When goals are met, we fade hours and plan a clean exit — often into a less-intensive support model or directly to school.

No waitlist

Tell us your child’s age and goals. We’ll tell you the honest hours.

Every family’s plan is different — and we’d rather have a real conversation than guess. One short call gets you a custom recommendation.

Parent FAQ

The questions families ask first.

Is 40 hours a week of ABA really necessary?

Sometimes — not always. The classic research on early-intensive ABA used 25–40 hour weeks for kids under 6 with significant skill delays, and that’s where the highest dosage gets recommended. For older kids, school-age learners, or families addressing focused goals, 10–20 hours is often the right call. We’ll never push for more than the assessment supports.

How soon will I see progress?

First few weeks are mostly rapport-building — we want your child running into sessions, not dragged in. Most families notice early changes around weeks 4–8: first independent requests, calmer transitions, longer attention spans. The bigger milestones (full sentences, toilet trained, sitting through a meal) usually land between months 3 and 9.

Can ABA hours go down over time?

Yes — and that’s the goal. Most kids who start in comprehensive ABA at 30–40 hours step down to 15–25 hours as they get closer to kindergarten, and many transition to focused ABA after that. The hours follow your child’s independence; they aren’t locked in.

What if my child also goes to school or daycare?

Very common, and very workable. Many school-age kids do 10–20 hours of focused ABA after school and on weekends. Younger kids in preschool often split time — half-day preschool plus half-day at our center. We coordinate with the school’s IEP team so the two settings reinforce each other instead of pulling against each other.

How do we know when to stop ABA?

Discharge happens when the goals you set together are met and generalized — your child uses the skills with new people, in new places, without prompts. We plan that fade-out months in advance, step the hours down gradually, and keep the door open for booster sessions if anything regresses. ABA isn’t meant to be forever.
