Welcome to the Child Development Institute

Research shows that high quality and intensive early intervention can make a significant difference in the life of your child with Autism Spectrum Disorder or Developmental Delay.

At the Child Development Institute we offer specialised Early Intervention programs based on the Early Start Denver Model (ESDM), an evidence-based intervention for children on the Autism Spectrum and with Developmental Delays.

Our programs are designed to give your child the skills they need to lead an independent life and to fully participate within their family and community


I would like to express our thanks for your help with James’ treatment for the last nine months.  Straight from his very first appointment it was clear that CDI was the right fit for James. He quickly  warmed to all the staff and always loved his visits.

James’ progress since starting at CDI has been amazing. When he started, he rarely talked at pre-school and would not interact with other children. Now, he has gained confidence, and happily plays with his peers. His play and social skills have really improved and continue to do so. I know that a large part of this is due to his time at CDI.  We will be forever grateful for the incredible boost that CDI provided.

What is the Early Start Denver Model?

The ESDM is a naturalistic, play-based intervention model for young children with neuro-developmental delays aged 12-60 months built on a strong evidence base of clinical trials.
It can be delivered across multiple settings including education settings, community clinics and the family home during typical play and daily routines.
Evidence supports the ESDM’s ability to accelerate a child’s development, particularly in the areas of social communication and cognition.

ESDM: A Multi-disciplinary Model

The ESDM Therapy delivered at the CDI considers all domains of the child’s development.
This is why we often see such rapid progress when compared to traditional forms of early intervention

Multi Disciplinary Model Autism Specific Early Intervention for Children

“We are so pleased with the improvements we have seen in our son since beginning ESDM therapy. The therapists have been amazing in their approach to connect with our little boy. Most importantly, our son always has a big smile on his face as soon as we arrive at the CDI. He enjoys every therapy session and has a great bond with his therapist.”

1:1 ESDM Clinic

The ESDM Clinic is the ideal introduction to the play partner approach of the ESDM. It prepares a child for both future therapies including ESDM Inclusion Readiness Program and our Mainstream Support Program. The ESDM clinic is a high quality, highly intensive, one-to-one therapy with an ESDM therapist. The goal is to bridge the learning gaps that have accumulated over time and to construct the building blocks a child needs for social interaction

Differences between ABA and ESDM

Early Childhood Social Therapy Group

This social therapy group targets the skills needed by children with ASD to participate fully in everyday life and to be included in a mainstream community education setting. The 3 hour group program facilitates the child’s learning, mastery and generalization of: 

  • Imitation skills, so they can learn from others
  • Social skills with adults and peers
  • Communication skills and Self-independence
  • Skills for transitioning between activities and participating in structured group time

The focus of the intervention is to target individual goals that work towards the child’s inclusion into natural settings and bringing the child back into the social loop.

School Readiness Program

The CDI School Readiness Program (SRP) has been developed to equip children with any developmental delays including ASD, with the necessary skills to enter their school setting with greater confidence and improved social skills.

Operating across 2 classrooms, the program is tailored to accommodate children who will be entering a Mainstream school setting, or a Supported school setting (School for Specific Purpose or a Support Unit within a mainstream school).

The program is led by Early Childhood Teachers and Occupational Therapists who have been trained to deliver the Early Start Denver Model.

Each session will be structured to reflect a typical Kindergarten environment.

Focus areas include:

  • Peer-to-peer relationships
  • Social awareness
  • Confidence and involvement
  • Fine motor strength and co-ordination
  • Cognitive skills
  • Personal independence skills expected of children in Kindergarten

ESDM in Mainstream

 The ESDM in Mainstream program was developed with the aim of supporting children within their early childhood setting and to provide guidance and strategies to their educators.  Our staff will visit your child’s centre, work with them directly as well as guiding their mainstream educators, enhancing inclusion and participation.

The following overarching learning outcomes are targeted:

  1. Settling into an educational environment and following daily routines
  2. Independently transitioning between routines, activities and tasks
  3. Participating in learning activities within small and large group play experiences
  4. Playing alongside their peers and educators
  5. Using play materials appropriately and increase their repertoire of functional play
  6. Participating in personal independence tasks
  7. Developing new and appropriate skills to communicate with peers and adults

Parent Coaching & Capacity Building

CDI acknowledges parents as the expert and primary carer for their child and aims to help create inclusive homes and communities for children with ASD.

Our parent capacity building programs aim to support parents in developing skills and confidence to know that each interaction with their child is benefiting their learning.

Weekly individual or group sessions are run by experienced ESDM Therapists who have been trained in the delivery of parent coaching.

A Career at the CDI Applying for an Intensive NDIS Plan

Speech and Language Pathology

To specifically support children in the area of communication, the CDI employs a Speech Pathology team who deliver various forms of Speech & Language Pathology, as well as Feeding therapy and consultation to our Intensive Early Intervention programs.

A child may benefit from 1:1 Speech clinics if they present with more complex challenges such as:

  • Motor speech disorders
  • Developmental language disorders
  • Augmented and Alternative Comunication
  • Dysphagia

 Speech therapy is delivered in 45 minute sessions in our centre with the parent present.

Feeding Therapy

The CDI delivers an evidence-based approach to feeding therapy called SOS. Like ESDM it is play-based and allows a child to interact with food in a fun, non-stressful way.

A child may benefit from SOS feeding therapy if they:

  • avoid all foods in a specific texture or food group
  • are able to eat less than 20 foods consistently
  • have ongoing choking or gagging during meal times
  • have poor weight gain


Feeding therapy is delivered in 1 hour sessions either in the home or at our centre with the parent present.

Supporting parents through their NDIS journey

Each CDI centre has a team member who can provide NDIS Support adn advice to enrolled families. Our support includes: 

  • Overview of plan types you can apply for and the process of requesting these
  • Advice on what evidence to collect from service providers
  • Guidance to help prepare a Family Impact Statement
  • Provision of a comprehensive NDIS progress report and quotation for  recommended therapy over the next 12 months

While the NDIS is a fantastic scheme, the process of attaining a ‘reasonable and necessary’ plan for a young child with ASD or Developmental Delay can be daunting. But we are here to help you navigate the journey and ensure you are as prepared as you can be with all the evidence to support your application for an Intensive Therapy Plan.

Self managed or Plan Managed NDIS funding can be used to cover costs of all services at the CDI.


“We’ve received a 12-month intensive plan from the NDIS review ….I would just like to thank you for all the support you have provided us and are excitedly looking forward to what’s ahead in Suventha’s development. From the bottom of my heart, I honestly feel as though the CDI was a blessing from God to us, and my family and I are so very thankful for how the CDI has given us hope.”

Yaso daughter aged 3 years


The ESDM is proven to work. Practiced worldwide, numerous clinical trials have validated the ESDM as a highly effective therapy for young children living with ASD, due to its comprehensive and naturalistic approach.

Clinical trials have shown the ESDM to provide greater improvement in cognitive and adaptive behaviour and language ability, while minimising the symptoms of autism.

Proven to be highly effective in both a one-to-one and group setting, there is a growing body of evidence to suggest the ESDM is also highly effective in a mainstream setting such as a childcare centre, pre-school or primary school, if delivered by ESDM trained educators.

Positive Outcomes - A CDI Case Study

At assessment this 3 year old child was meeting some milestones on Level 1 on the ESDM Curriculum Checklist which is equivalent to the developmental age of a 12 month old in terms of his skills across all domains. He is now entering level 3 on the ESDM Curriculum Checklist, which is equivalent to a 2 – 3 year old.

This demonstrates that he has made the equivalent of 12 months developmental progress across all domains in 5 months of therapy.

On entering the program this child was very unresponsive, with few social skills, and no social smiles. He had difficulty expressing his emotions and became easily frustrated.

He has now:

  • Developed the words and skills to make his needs and feelings known
  • Has significantly improved social skills, both at home and while in our centre
  • Addresses staff members by name and is learning the names of his peers
  • Is able to share toys and interactions with his peers
