ABA Therapy Hours: 20 vs 30 Per Week - A Parent's Guide
In short: The right number of ABA therapy hours depends on your child's age, needs, and goals. 20 hours per week is often a good starting point for building foundational skills, while 30 hours may be recommended for more intensive intervention, especially for younger children or those with significant challenges. Both options are typically covered by insurance, including Medicaid, and a BCBA will help determine the best plan for your family.
Key takeaways
- ABA therapy hours are individualized based on a child's needs, not a one-size-fits-all number.
- 20 hours per week is often used for skill-building and maintenance; 30 hours is more intensive and common for early intervention.
- Insurance, including Medicaid, usually covers ABA therapy, but prior authorization and medical necessity documentation are required.
- The BCBA (Board Certified Behavior Analyst) determines the recommended hours after a comprehensive assessment.
Understanding ABA Therapy Hours: What Do They Mean?
When your child is diagnosed with autism spectrum disorder (ASD), one of the first questions you may face is: how many hours of ABA therapy should they receive? The answer is not a simple number-it depends on your child's unique strengths, challenges, and goals. ABA (Applied Behavior Analysis) therapy is a data-driven, evidence-based approach that helps children develop communication, social, and daily living skills while reducing challenging behaviors.
The number of recommended hours per week typically falls into two common ranges: 20 hours or 30 hours. But what do these numbers actually mean for your child and your family? Let's break it down.

Why 20 Hours vs 30 Hours? The Science Behind the Recommendation
Research has shown that intensive ABA therapy (often 30-40 hours per week) can lead to significant gains, especially for young children. However, not every child needs that level of intensity. The decision is based on a thorough assessment by a Board Certified Behavior Analyst (BCBA).
What Does 20 Hours Per Week Look Like?
A 20-hour per week schedule typically means 4 hours of therapy per day, 5 days a week. This is often recommended for children who:
- Have already acquired some foundational skills (e.g., communication, imitation)
- Are working on more advanced social or academic skills
- Need less support for challenging behaviors
- Are in school part-time and need therapy to supplement learning
This schedule allows for a balanced approach-your child still has time for school, play, and family activities while receiving focused intervention.
What Does 30 Hours Per Week Look Like?
A 30-hour schedule is more intensive, often involving 6 hours per day, 5 days a week. This is typically recommended for:
- Young children (ages 2-5) who are newly diagnosed and need to build foundational skills
- Children with significant communication delays or high-frequency challenging behaviors
- Those who require a higher level of support to make progress
At this intensity, therapy may be delivered in a clinic, at home, or in a combination of settings. The goal is to maximize learning opportunities throughout the day.
Factors That Influence the Recommended Number of Hours
Your BCBA will consider several factors when determining the right hours for your child:
Age and Developmental Stage
Younger children often benefit from more intensive therapy because their brains are more plastic and receptive to learning. The earlier the intervention, the better the outcomes. For a 2-year-old, 30 hours may be recommended to build foundational skills like eye contact, imitation, and communication. An older child who has already made progress may need fewer hours.
Severity of Needs
Children with more significant delays or challenging behaviors may require more hours to address all target areas. The BCBA will assess your child's skills in areas like language, social interaction, play, self-help, and behavior management.
Insurance and Funding
ABA therapy is typically covered by insurance, including Medicaid and many private plans. However, insurance companies often require a medical necessity letter from your BCBA to authorize a specific number of hours. They may also have caps or limits. Our free matching service can help you find a provider who accepts your insurance and understands the authorization process.
Family Schedule and Resources
Your family's daily routine matters. Can you commit to driving your child to therapy 5 days a week? Do you have other children or work commitments? The BCBA will work with you to create a schedule that is realistic and sustainable.

Cost and Insurance Coverage for 20 vs 30 Hours
ABA therapy can be expensive without insurance-costs can range from $50 to $150 per hour. With insurance, your out-of-pocket costs depend on your plan's deductible, copay, and coinsurance. Many families pay little to nothing after insurance, especially if they have Medicaid.
For example, if your child receives 20 hours per week at $100/hour, the weekly cost would be $2,000. At 30 hours, it would be $3,000. Insurance typically covers this, but you'll need prior authorization. Our service can connect you with providers who have experience navigating insurance requirements.
How to Decide: Questions to Ask Your BCBA
When discussing hours with your BCBA, ask these questions:
- What specific goals will we target with 20 vs 30 hours?
- How will progress be measured, and at what point might we reduce hours?
- What does a typical day look like at each intensity level?
- How will therapy integrate with school or other therapies (speech, OT)?
- What is the evidence supporting this recommendation for my child?
The BCBA should provide clear reasoning and be open to adjusting hours as your child progresses.
Common Mistakes to Avoid
Parents often fall into these traps when choosing ABA hours:
- Assuming more hours are always better: Quality matters. Too many hours can lead to burnout for both child and family.
- Ignoring your child's cues: If your child is showing signs of stress or fatigue, it may be time to adjust the schedule.
- Not considering other therapies: ABA should complement speech, occupational therapy, or school, not replace them entirely.
- Waiting too long to start: Early intervention is key. Even 20 hours can make a big difference if started early.
