The Australian Early Development Census (AEDC) is a nationwide data collection of early childhood development.

The AEDC provides evidence to support health, education and community policy and planning. AEDC data highlights what is working well and what can be improved to support children and their families. AEDC data are collected every three years. The sixth collection took place in 2024.

Who is the AEDC for?

AEDC data can help identify how children’s development is supported in the community - what is working well and where there are gaps.

AEDC data can help early childhood educators shape their programs to enrich children’s development.

By taking part, families add to important knowledge for research and policy that helps to identify the needs of children, families and communities. Parents don’t need to provide any information, and children don’t lose any class time.

When children and families are supported, policymakers and governments build a better future for their communities.

The AEDC provides researchers with robust data about children’s development and can be accessed in de-identified formats and through data linkage.

The AEDC provides schools with data about children’s development, to help strategic and quality improvement planning.

AEDC in action

Everton Park State School (QLD)

Everton Park State School used the data to connect with local early childhood education and care services. It was decided to improve children’s transition to school by employing a Prep Transition Officer to develop a shared understanding of school readiness and work on transitions with early childhood services, parents and children.
