How Many Hours of ABA Therapy Does My Child Need?

Understanding ABA therapy intensity and what's right for your child.

Updated January 20258 min read

Quick Answer

Most children benefit from 10-40 hours per week of ABA therapy. Young children (2-5 years) typically need higher intensity (25-40 hours), while school-age children and teens often do well with 10-25 hours scheduled around school.

What Determines ABA Therapy Hours?

There's no one-size-fits-all answer. Your child's BCBA will recommend therapy hours based on several factors:

  • Age - Younger children typically need more intensive therapy
  • Support needs level - Higher support needs may require more hours
  • Specific goals - Communication, behavior, or life skills focus
  • School schedule - Balancing therapy with education
  • Family capacity - What your family can realistically manage
  • Progress rate - Adjusting intensity based on gains

Recommended Hours by Age

Toddlers (2-3)

Critical early intervention window

25-40 hours/week
Preschool (3-5)

Pre-K readiness focus

20-35 hours/week
School-Age (6-12)

After-school scheduling

10-25 hours/week
Teens (13-18)

Life skills focus

10-20 hours/week

Why Early Intervention Requires More Hours

Research shows that early intensive behavioral intervention (EIBI)—typically 25+ hours per week for children under 5—produces the best long-term outcomes. During early childhood, the brain is most plastic and responsive to intervention.

Children who receive intensive early ABA often:

  • Develop more functional language
  • Achieve higher IQ gains
  • Require less support as they age
  • Are more likely to attend mainstream classrooms

Quality Over Quantity

More hours isn't always better. Consistent, quality therapy with good generalization and parent involvement often produces better outcomes than maximizing hours alone.

Can Therapy Hours Decrease Over Time?

Yes! The goal of ABA is to teach skills that lead to independence. As your child masters skills:

  1. Intensive phase - High hours for rapid skill building
  2. Generalization phase - Practicing skills across settings
  3. Maintenance phase - Reduced hours, monitoring progress
  4. Consultation phase - Occasional check-ins, parent support

Frequently Asked Questions

How many hours of ABA therapy does my child need?

Recommended hours vary from 10-40 hours per week based on your child's age, needs, and goals. Young children (2-5) typically benefit from 25-40 hours, while older children may need 10-20 hours. A BCBA assessment determines the optimal intensity.

Is part-time ABA therapy effective?

Yes, part-time ABA (10-20 hours/week) can be effective, especially for school-age children, those with milder support needs, or as a step-down from intensive therapy. Any ABA is better than none.

How long does ABA therapy take to work?

Most families see initial progress within 3-6 months. Significant skill gains typically occur over 1-2 years of consistent therapy. The timeline depends on therapy intensity, child's age, and specific goals.

Can my child do less ABA hours as they improve?

Yes! As children master skills and generalize them across settings, hours are often gradually reduced. The goal of ABA is independence, not lifelong therapy. Many children transition to maintenance schedules.
