What age is ESDM designed for?

ESDM is specifically for children between 12 and 48 months old. It focuses on early developmental milestones like joint attention, imitation, and first words.

Can ABA be used for toddlers?

Yes, ABA can be adapted for toddlers through natural environment teaching and play-based methods. Many BCBAs specialize in early intervention.

Is ESDM covered by insurance?

ESDM itself is often billed under ABA codes, so it is typically covered by private insurance and Medicaid if it is part of a comprehensive ABA program. Always verify with your provider.

Which is more effective for a 2-year-old?

Both are effective, but ESDM was designed specifically for this age. Research shows it improves IQ, language, and adaptive behavior. ABA also works well when delivered in a developmentally appropriate way.

How many hours per week are recommended?

ESDM typically recommends 10-20 hours per week. ABA can range from 10-40 hours, but for very young children, experts often suggest starting with 10-15 hours and adjusting based on progress.

Can I combine ESDM and ABA?

Yes, many providers integrate ESDM principles into an ABA framework. A BCBA trained in both can create a blended approach that uses play-based teaching while collecting data on specific goals.

ESDM vs ABA for Very Young Child: A Parent's Guide

In short: ESDM (Early Start Denver Model) is a play-based, developmental approach for very young children (12-48 months) with autism, blending ABA principles with relationship-building. Traditional ABA is more structured and data-driven, often using discrete trial training. Both are evidence-based and can be covered by insurance or Medicaid. The best choice depends on your child's age, needs, and family preferences.

Understanding the Two Approaches

When your very young child receives an autism diagnosis, you may hear about two major therapy options: the Early Start Denver Model (ESDM) and Applied Behavior Analysis (ABA). Both are evidence-based, but they differ in philosophy, structure, and how they engage a toddler or preschooler. This guide breaks down the key differences to help you make an informed decision.

What Is the Early Start Denver Model (ESDM)?

ESDM is a comprehensive, play-based intervention for children ages 12 to 48 months with autism. Developed by Drs. Sally Rogers and Geraldine Dawson, it combines developmental principles with ABA strategies. The goal is to accelerate a child's development in all areas, especially social communication, language, and play.

Core Features of ESDM

Naturalistic and play-based: Therapy happens during everyday activities like playing, snacking, or bath time.
Child-led: The therapist follows the child's interests and builds skills within those activities.
Parent involvement: Parents are trained to use ESDM strategies at home, making it a 24/7 approach.
Focus on relationships: ESDM emphasizes joint attention, imitation, and emotional engagement.
Curriculum-based: It uses a specific teaching checklist to track progress across domains.

Who Is ESDM Best For?

ESDM is specifically designed for very young children-typically between 12 and 48 months old. It works best for children who are just beginning to learn foundational skills like eye contact, pointing, and simple words. If your child is a toddler or young preschooler and you prefer a gentle, play-based approach, ESDM may be a great fit.

What Is Applied Behavior Analysis (ABA)?

ABA is a broader science of behavior and learning. For young children with autism, ABA therapy uses principles of reinforcement to teach new skills and reduce challenging behaviors. While ABA can be delivered in many ways, for very young children it often includes natural environment teaching (NET) and discrete trial training (DTT).

Core Features of ABA

Data-driven: Therapists collect data on every skill to measure progress and adjust teaching.
Structured teaching: Some sessions may involve sitting at a table for short, focused trials (DTT).
Individualized: A Board Certified Behavior Analyst (BCBA) designs a plan based on your child's unique needs.
Flexible intensity: ABA can range from 10 to 40 hours per week, depending on the child's needs.
Skill building across domains: Targets include communication, social skills, self-help, and academics.

Who Is ABA Best For?

ABA is effective for children of all ages, including toddlers. It is especially helpful for children who need more structure or have significant challenging behaviors. Many ABA providers offer center-based, home-based, or school-based therapy, giving families flexibility.

Key Differences Between ESDM and ABA

Philosophy and Approach

ESDM is rooted in developmental psychology and sees the child as an active learner who builds skills through relationships. ABA is rooted in behaviorism and focuses on observable behaviors and environmental factors. In practice, this means ESDM sessions look like play, while ABA sessions may include more direct teaching.

Age Range and Focus

ESDM is only for children under 4 years old. ABA can be used from infancy through adulthood. For a 2-year-old, both can work, but ESDM is specifically tailored to that age group's developmental needs.

Parent Training

ESDM requires extensive parent coaching-often weekly sessions where parents learn to integrate strategies into daily routines. ABA also includes parent training, but the amount varies by provider. In ESDM, parents are considered co-therapists; in ABA, parents are partners but the BCBA leads the plan.

Setting and Intensity

ESDM is almost always delivered in natural settings (home, daycare, community) and typically involves 10-20 hours per week. ABA can be delivered in centers, homes, or schools, and intensity can range from 10 to 40 hours. For very young children, experts often recommend starting with fewer hours and increasing as needed.

Cost and Insurance Coverage

Both ESDM and ABA are considered medically necessary treatments for autism. Most private insurance plans, including those regulated by state mandates, cover ABA therapy. Medicaid (including state-specific programs like California's Medi-Cal or New York's Medicaid) also covers ABA for children with an autism diagnosis.

ESDM is less commonly billed separately; it is often delivered by providers who also use ABA codes. Some clinics offer ESDM as a specific program and bill under ABA. Always check with your insurance company and ask providers about coverage. A free service like Start with ABA can help you find vetted, BCBA-led providers who accept your insurance and offer either therapy.

How to Choose Between ESDM and ABA

Consider Your Child's Age and Development

If your child is under 3 and not yet speaking, ESDM may be a strong choice because it targets early social communication skills. If your child is older or has more advanced skills, traditional ABA can be tailored to their level.

Think About Your Family's Style

Do you prefer a child-led, play-based approach? ESDM might feel more natural. Do you want clear data and structured goals? ABA may appeal more. Many families find that a blend works best-starting with ESDM for relationship building and adding ABA elements as the child grows.

Look at Provider Availability

Not all areas have ESDM-trained providers. ABA is more widely available, especially through large agencies. If you live in a rural area, ABA might be easier to access. Use a matching service to explore options near you.

Practical Tips for Getting Started

Get a comprehensive evaluation: A developmental pediatrician or psychologist can recommend the best therapy based on your child's profile.
Ask about training: For ESDM, ensure the therapist is certified. For ABA, confirm the BCBA has experience with very young children.
Start with a trial period: Many providers offer a free consultation or trial session. Observe how your child responds.
Involve your whole team: Speech, occupational, and physical therapy can complement either approach.
Trust your gut: You know your child best. If a therapy doesn't feel right, it's okay to switch.

Common Mistakes to Avoid

Waiting too long: Early intervention is critical. Start therapy as soon as possible after diagnosis.
Choosing based on cost alone: Both therapies are often covered by insurance. Focus on fit and quality.
Assuming one is better: There is no one-size-fits-all. Some children thrive with ESDM, others with ABA.
Ignoring parent training: The more you learn, the more you can support your child's growth at home.
