10 vs 40 Hours ABA Therapy: What Is Right for Your Child?

In short: ABA therapy hours are not one-size-fits-all. A 10-hour per week plan often works for children with specific skill targets or who are in school, while 40 hours is a comprehensive model typically recommended for younger children with more intensive needs. The right choice depends on your child's age, current skills, challenging behaviors, and family schedule, all discussed with a BCBA. Our free service can match you with vetted providers who will help determine the best hours for your child.
Key takeaways
- ABA hours are individualized; there is no single 'right' number for every child.
- 10 hours per week is often a focused model for specific goals like potty training or social skills.
- 40 hours per week is a comprehensive model, common for young children with significant delays or high support needs.
- Hours are determined by a BCBA after a thorough assessment, not by a parent or insurance alone.
Understanding ABA Therapy Hours: A Personalized Approach
When you first explore Applied Behavior Analysis (ABA) therapy for your child, one of the most common questions is, "How many hours per week does my child need?" You may hear numbers like 10 hours or 40 hours and wonder what is best. The simple truth is that ABA therapy is not a one-size-fits-all treatment. The right number of hours depends on your child's unique strengths, challenges, age, and family situation. This guide will help you understand the difference between a 10-hour and a 40-hour ABA model, what factors influence the recommendation, and how to make an informed decision with your Board Certified Behavior Analyst (BCBA).

What Does 10 Hours of ABA Per Week Look Like?
A 10-hour per week ABA plan is often called a focused or targeted model. It is typically recommended when a child has a smaller number of specific skill deficits or challenging behaviors that need addressing.
When 10 Hours Might Be Right
- School-aged children: If your child is in school full-time, 10 hours of ABA can be scheduled after school or on weekends without overwhelming their day.
- Specific skill goals: The focus might be on a few key areas, such as toileting, self-help skills, or improving social interactions with peers.
- Mild to moderate needs: For children who have some foundational skills but need extra support in specific areas, a focused model can be very effective.
- Family schedule: If your family has limited availability or your child has many other activities, 10 hours can be a manageable commitment.
What a 10-Hour Week Involves
In a 10-hour plan, a Registered Behavior Technician (RBT) typically works directly with your child for 1-2 hours per day, several days a week. The BCBA will supervise regularly, often weekly or bi-weekly, to adjust the plan. The focus is on intensive practice of a few high-priority skills. For example, a child might work on requesting items, following simple instructions, and tolerating transitions.
What Does 40 Hours of ABA Per Week Look Like?
A 40-hour per week ABA plan is known as a comprehensive model. It is designed for children who need intensive, all-day support across many developmental domains. This model is most common for younger children, especially those diagnosed with autism spectrum disorder (ASD) before age 5.
When 40 Hours Might Be Recommended
- Young children (under 5): Early intervention research often supports higher intensity for very young children to build foundational skills like communication, play, and self-regulation.
- Significant skill delays: If a child has substantial delays in multiple areas (e.g., language, social, self-care, motor skills), comprehensive ABA can address them all.
- High-frequency challenging behaviors: For children who engage in behaviors like aggression, self-injury, or severe tantrums, more hours allow for consistent behavior management and teaching replacement skills.
- Minimal school or daycare: If your child is not yet in a school program, 40 hours of ABA can fill the day with structured learning and play.
What a 40-Hour Week Involves
In a comprehensive model, your child might receive 6-8 hours of ABA per day, 5 days a week. This includes one-on-one time with an RBT, group activities, and natural environment teaching (learning in everyday settings like the park or grocery store). The BCBA will supervise frequently, often multiple times per week, to ensure the plan is working. The goal is to create a full-day learning environment that targets communication, social skills, daily living skills, and reducing interfering behaviors.

How Are ABA Hours Determined?
The number of hours is not chosen by a parent or guessed by a provider. It is based on a formal assessment process. Here is how it works:
The Role of the BCBA Assessment
A BCBA will first conduct a comprehensive assessment, often using tools like the VB-MAPP (Verbal Behavior Milestones Assessment and Placement Program) or the ABLLS-R (Assessment of Basic Language and Learning Skills). This assessment identifies your child's current skill level across dozens of domains, as well as any challenging behaviors that need intervention.
Factors That Influence the Recommendation
- Age of the child: Younger children often benefit from more hours to capitalize on early brain development.
- Current skill level: A child with more significant delays will likely need more hours to catch up.
- Severity of challenging behaviors: Behaviors that are dangerous or severely impact learning require more intensive intervention.
- Family goals and resources: Your family's schedule, other children, work commitments, and ability to implement strategies at home all matter.
- Funding source: Insurance plans and Medicaid may have specific guidelines for what hours they will authorize. Our free matching service can help you find providers who work with your insurance.
Cost and Insurance Coverage for ABA Hours
ABA therapy is a covered benefit under many insurance plans, including Medicaid. However, the number of hours authorized can vary.
Insurance Authorization
Most insurance companies require a BCBA to submit a treatment plan with a recommended number of hours. They may approve hours in blocks (e.g., 10, 20, 30, or 40 per week) and require periodic re-authorization. It is important to work with a provider who understands how to navigate insurance. Our free service can match you with vetted, BCBA-led providers who handle insurance approvals.
Cost Without Insurance
Without insurance, ABA therapy can cost between $50 and $150 per hour. A 10-hour week might cost $500-$1,500 per week, while a 40-hour week could range from $2,000 to $6,000 per week. Many providers offer sliding scale fees or payment plans, and some states have waivers that help cover costs.

Common Mistakes Parents Make When Choosing Hours
Making the decision about ABA hours can be stressful. Avoid these common pitfalls:
- Assuming more hours is always better: More hours are not automatically better. A child who is overwhelmed may not learn effectively. Quality matters as much as quantity.
- Choosing based on fear: Some parents worry that if they don't take 40 hours, their child will miss out. The right plan is one that fits your child's needs and your family's life.
- Ignoring your child's tolerance: If your child is showing signs of burnout (e.g., increased meltdowns, refusing to participate), the hours may need to be adjusted.
- Not involving your BCBA in the decision: Your BCBA is the expert. Trust their assessment and ask questions if you are unsure.
How to Decide: Practical Tips for Parents
Here is a step-by-step approach to help you and your BCBA decide on the right hours:
Step 1: Get a Thorough Assessment
Start with a comprehensive evaluation from a BCBA. This is the foundation for any hour recommendation.
Step 2: Discuss Your Family's Goals
What do you want your child to achieve? Is it learning to communicate, playing with siblings, or being ready for school? Your goals will influence the intensity needed.
Step 3: Consider Your Child's Current Schedule
Think about school, therapies (speech, OT), and family time. A 40-hour plan may not be feasible if your child is in school full-time.
Step 4: Start with a Trial Period
Many providers will start with a recommended number of hours and adjust after a few weeks based on your child's progress and feedback. Be open to changing the plan.
