Probably not. While 40 hours per week is often cited as the gold standard for ABA therapy, most children don’t need that much. The right number of hours depends on your child’s age, needs, and daily life. At Treetop, we build therapy plans starting as low as 15 hours per week, sometimes less, because progress matters more than a number on a schedule.

Where the 40-Hour Recommendation Comes From

The 40-hour figure traces back to Dr. Ivar Lovaas’s 1987 study, which showed significant outcomes for young children receiving intensive early intervention. That research was groundbreaking. It also involved a very specific group of children under very specific conditions.

Since then, the field has evolved. Decades of additional research have shown that many children make meaningful progress with fewer hours. The 40-hour model remains appropriate for some kids, particularly very young children with significant support needs. But it was never meant to be a one-size-fits-all prescription.

When Fewer Hours Make Sense

There are plenty of situations where part-time ABA therapy is the better choice.

School-age children. If your child is in school full-time, pulling them out for 40 hours of therapy isn’t realistic or healthy. They need time with peers, time in the classroom, and time to just be a kid. A focused 15 to 20 hour plan built around the school day often produces better results because the child isn’t exhausted.

Teens. Older kids and teenagers typically benefit from fewer, more targeted hours. Their therapy goals look different. They’re working on independence, social skills, and life skills, not the foundational behaviors that drive high-hour recommendations for toddlers.

Children with milder support needs. Not every child on the spectrum needs intensive intervention. Some kids need help with specific skills or behaviors, and a focused plan of 10 to 20 hours per week addresses that without taking over their entire life.

Working families. You have jobs, other kids, and a household to run. A therapy schedule that demands 8 hours a day, 5 days a week can break a family. The best therapy plan is one your family can actually sustain.

What the Research Actually Says

The research on ABA therapy hours is more nuanced than most providers let on.

A 2019 study published in Behavior Analysis in Practice found that children receiving 12 to 25 hours per week showed significant skill gains across multiple domains. A meta-analysis in the Journal of Autism and Developmental Disorders confirmed that while more hours generally correlate with better outcomes, the relationship isn’t linear. Going from 0 to 15 hours makes a huge difference. Going from 25 to 40 often shows diminishing returns.

What matters more than raw hours is the quality of those hours. A well-designed, BCBA-supervised program with clear goals and consistent data collection will outperform a bloated schedule filled with unfocused time.

How Treetop Approaches Hours Differently

When you come to Treetop, your child’s BCBA doesn’t start with a number and work backward. They start with your child.

The assessment looks at your child’s current skills, the areas where they need support, their age, their school schedule, and your family’s situation. From there, we recommend an hour range that fits your child’s actual needs.

For some families, that’s 30 or more hours per week. For many, it’s 15 to 25. For some teens and older kids, it might be even less. We adjust as your child progresses, because the goal isn’t to keep hours high. The goal is to help your child build skills and eventually need less therapy, not more.

We measure success by your child’s progress, not our billing hours.

Whether your family is in Charlotte or Winston-Salem, we offer both in-home and center-based options that flex around your schedule. We serve children ages 2 through 18.

Frequently Asked Questions

Is 40 hours of ABA therapy too much for my child?

It depends on your child’s age and needs. For very young children (under 5) with significant support needs, 30 to 40 hours can be appropriate. For school-age children, teens, or kids with milder needs, that many hours is often unnecessary and can lead to burnout for both the child and the family.

Can my child make progress with part-time ABA therapy?

Yes. Research consistently shows that children can make meaningful progress with 15 to 25 hours per week, especially when the program is well-designed and supervised by a qualified BCBA. Quality and consistency matter more than sheer volume.

How do I know how many hours of ABA therapy my child needs?

A thorough assessment by a Board Certified Behavior Analyst (BCBA) is the best starting point. They’ll evaluate your child’s skills, identify areas for growth, and recommend an hour range based on clinical evidence, not a standard template. At Treetop, we reassess regularly and adjust hours as your child progresses.

Will insurance coverage for ABA therapy fewer than 40 hours of ABA therapy?

Most insurance plans cover the number of hours recommended by your child’s BCBA, whether that’s 15 hours or 40. The key is that the recommendation is supported by a clinical assessment and treatment plan. Our team handles insurance authorization so you don’t have to navigate that process alone.
