What is the Early Start Denver Model (ESDM)?

​​​

The Early Start Denver Model (ESDM) is a comprehensive, evidence-based early intervention therapy specifically designed for young children with autism spectrum disorder (ASD) aged 1 to 6 years old.  Developed by leading researchers in the field of autism and early childhood development, ESDM combines the principles of applied behavior analysis (ABA) with naturalistic, relationship-based strategies to create a holistic, individualised therapy. ESDM is rooted in play-based, relationship-driven methods that foster communication, social, and cognitive skills. The goal of ESDM is to enhance young children’s communication, social, and cognitive abilities in a nurturing and engaging environment. ESDM focuses on development and capacity building to help children build foundational skills within their daily routines.

​

How does ESDM work?

​​​

ESDM’s core objective is to promote meaningful, measurable development in children with ASD. Specifically, ESDM aims to:
 

• Foster communication and language skills.

• Enhance social skills and interpersonal engagement.

• Support cognitive development and critical thinking.

• Build adaptive behaviors and self-regulation.

• Increase emotional understanding and the ability to connect with others.

​

ESDM integrates structured, evidence-based teaching methods with child-led activities and play, making learning enjoyable and natural for children. Here’s a breakdown of how ESDM works:
 

1. Assessment: A child’s strengths, interests, and developmental needs are assessed to create a tailored program.

2. Customized Learning Objectives: Based on assessment results, specific developmental goals are set across areas such as language, motor skills, social engagement, and behavior management.

3. Play-Based Learning: Each learning session is embedded in play and daily routines, focusing on activities that the child finds interesting. This makes learning enjoyable and helps reinforce the development of essential skills.

4. Parent Involvement: Parents and caregivers are encourage to be part of the ESDM process, so that parents can use ESDM principles at home, which enhances the continuity of learning.

5. Naturalistic Teaching: Unlike traditional, highly structured therapy, ESDM uses naturalistic teaching in everyday settings. This allows children to practice new skills in real-life contexts, making it easier for them to generalize and retain their learning.

 

By working in a child’s natural environment and focusing on relationship-building, ESDM creates a safe space where children can express themselves, develop essential skills, and build social connections.

​​

ESDM works to make learning an enjoyable part of each child’s daily life, empowering them to actively engage with peers, family, and caregivers in meaningful ways.

​

Is ESDM Effective and Evidence-Based?

​

Yes, ESDM is a thoroughly researched, evidence-based intervention model. Numerous studies have demonstrated its effectiveness in helping young children with autism achieve significant developmental milestones. Key findings supporting ESDM include:
 

• Positive Developmental Gains: Research shows that ESDM promotes improvements in social, language, and cognitive skills, as well as adaptive behaviors, which are essential for long-term development.

• Brain Function Changes: Studies have indicated that ESDM may influence brain activity in young children with autism, making it more similar to that of neurotypical children. This suggests ESDM can positively impact the way a child’s brain processes social information.

• Increased Engagement: ESDM’s play-based, engaging approach encourages children to actively participate and communicate, resulting in better learning outcomes and reduced stress during sessions.

• Sustained Progress: The naturalistic, adaptive approach of ESDM helps children retain and apply learned skills beyond therapy settings, making it easier for them to engage meaningfully with peers and family.
   

Because of these benefits, ESDM has gained recognition as a gold standard for early autism intervention.

​

What Principles Does ESDM Apply?

​

The Early Start Denver Model is guided by several core principles that make it uniquely effective for young children with autism. Here are the foundational principles that define the ESDM approach:

​

1. Relationship-Based Learning
   
   ESDM emphasizes creating warm, trusting relationships between the child and the therapist. This relationship forms the foundation for learning, as children feel safe, connected, and motivated to engage. Building social bonds is critical, as it helps children develop the desire to communicate, play, and connect with others.
    

2. Developmentally Appropriate Goals
   
   ESDM uses goals that are aligned with typical developmental milestones to guide each child’s learning path. By focusing on skills that would be age-appropriate for neurotypical children, ESDM helps bridge developmental gaps while respecting each child’s unique abilities and pace.
    

3. Naturalistic Teaching Techniques
   
   Skills are taught within a child’s natural environment, using play, everyday routines, and child-led activities. This makes learning feel like a natural part of life and encourages children to use their skills in real-world situations.
    

4. Behavioral Principles and Positive Reinforcement
   
   ESDM incorporates elements of applied behavior analysis (ABA), such as positive reinforcement, to encourage desired behaviors. For example, when a child attempts to communicate or interact, they receive positive reinforcement through praise, affection, or a preferred activity, which helps reinforce social and communicative behaviors.
    

5. Active Parental Involvement
   
   Parents and caregivers play an active role in ESDM. The model provides training and support for parents so they can practice ESDM techniques at home, strengthening their child’s learning and promoting a consistent environment. This partnership enhances progress, as children are surrounded by supportive learning opportunities throughout the day.
    

6. Focus on Social Engagement
   
   One of the primary objectives of ESDM is to foster social engagement by teaching children to respond to social cues and initiate interactions with others. By developing these skills early, children are better prepared for future social environments, including school settings.
    

7. Flexible, Child-Led Approach
   
   ESDM sessions are designed to follow the child’s lead, focusing on what interests them most. This approach keeps children engaged and motivated to learn, as they explore areas they find rewarding while building new skills.

​

What is the Difference Between ESDM and ABA for Early Intervention?
 

While ESDM is based on principles from ABA, it is distinct in its approach:
 

• Naturalistic Setting: Unlike the often structured, formal sessions in ABA, ESDM uses natural, everyday interactions for teaching.

• Child-Led Approach: ESDM emphasizes following the child’s lead, making learning activities enjoyable and organic, whereas traditional ABA may be more therapist-led.

• Focus on Social and Emotional Connections: ESDM gives equal importance to social engagement, unlike some ABA programs, which focus more on compliance and skill mastery.

• Integration with Play: ESDM uses play-based interactions, while ABA may use more directive teaching techniques.

Why Does ESDM Use Least-to-Most Prompting?

The “least-to-most” prompting technique in ESDM encourages independence by offering the child minimal assistance initially and gradually increasing support as needed. This approach:
 

• Builds confidence as children learn to accomplish tasks with minimal support.

• Encourages problem-solving and self-initiation.

• Helps therapists observe a child’s abilities and adapt prompts based on the child’s immediate needs.
   

By fostering independence, children are more likely to retain and apply new skills outside therapy sessions.
 

What is Being a Helpful Play Partner in ESDM?
 

In ESDM, a therapist or caregiver acts as a "Helpful Play Partner," following the child’s interests to create interactive, meaningful play. Being a Helpful Play Partner involves:
 

• Observing and responding to the child’s play preferences.

• Engaging with the child on their level, following their lead.

• Introducing gentle challenges to encourage skill-building.

• Reinforcing positive behaviors and encouraging the child to explore new skills
  .

This role encourages a positive, productive relationship, helping the child feel safe, supported, and motivated to learn.
 

How Does ESDM Teach, Implement, and Achieve Individualized Goals?

ESDM employs a personalised approach to achieve individualised goals by:
 

1. Assessment and Goal Setting: Initial assessments help set goals based on the child’s unique developmental needs.

2. Teaching through Natural Interactions: Goals are achieved through play and everyday routines, with activities specifically designed to target these goals.

3. Regular Progress Monitoring: Therapists continuously assess the child’s progress, adjusting goals and teaching techniques as the child advances.

4. Collaborative Parent Involvement: Parents receive guidance to reinforce goals at home, ensuring continuity and consistency.

This combination of tailored instruction and naturalistic, engaging activities helps each child reach their unique developmental milestones.

How Do We Assess a Child’s Baseline to Establish Initial Goals?

Baseline assessments in ESDM involve comprehensive evaluations that consider:
 

1. Developmental Screening: Tools like the Early Start Denver Model Curriculum Checklist are used to assess skills across communication, social interaction, cognition, and behavior.

2. Family Input: Parents provide insights into the child’s strengths, preferences, and needs.

3. Observation: Therapists observe how the child interacts with others and responds to various activities.

This initial assessment provides a clear picture of the child’s abilities and helps set a foundation for goal development.
 

How Many Goals Are Targeted Each Term (12-Week Period)?
 

Typically, ESDM targets around 12-15 goals per term. Goals span different areas such as language, motor skills, social engagement, and self-care. By setting focused, achievable goals over each 12-week period, ESDM ensures that children make consistent, meaningful progress.
 

How Are Goals Stepped Up in ESDM?
 

In ESDM, once a child achieves an initial goal, the challenge is gradually increased by:
 

1. Expanding Skills: For example, if a child learns to respond to simple requests, the goal may evolve to understanding and responding to multi-step instructions.

2. Introducing New Contexts: Goals may be adapted to different settings or interactions, helping children generalize their learning.

3. Increasing Independence: Over time, the child is encouraged to perform skills with less prompting, boosting their confidence and autonomy.

This incremental approach allows children to build on their successes and feel supported as they reach new milestones.
