AEDC for communities

Investing time, effort and resources in children’s early years – when their brains are developing rapidly  – brings lifelong benefits to them and to the whole community.

The environments and experiences children are exposed to from pregnancy through to school age shape their development.

Why the AEDC is important

The Australian Early Development Census (AEDC) measures how children have developed by the time they start their first year of full-time school. The AEDC collects data every three years in schools across Australia and reports children’s results in 5 key areas of early childhood development called domains.

South Australia’s 2018 AEDC results show that while more than 50% of children are developmentally on track, some are developmentally at risk and nearly 1 in 4 children are arriving at school developmentally vulnerable on 1 or more AEDC domains.

Developmental vulnerability on 1 or more AEDC domains can affect lifelong education, health and wellbeing outcomes.

The AEDC can be used as a holistic measure of child development in your community and help you understand how to best support children and families.

There are developmentally vulnerable children in all South Australian communities.

Some communities have seen improvement in their AEDC results over time.

The AEDC provides a strong evidence base that community organisations and local government can use in collaborative planning, implementation and evaluation.

Find out more in the community section of the AEDC website.

Understanding the AEDC

The AEDC provides comprehensive early childhood data at a community, jurisdictional and national level. It measures 5 important areas of early childhood development called domains.

Physical health and wellbeing

Children's physical readiness for the school day, physical independence and gross and fine motor skills.

Emotional maturity

Children's pro-social and helping behaviours, and absence of anxious and fearful behaviour, aggressive behaviour, and hyperactivity and inattention.

Language and cognitive skills (school based)

Children's basic literacy, interest in literacy, numeracy and memory, advanced literacy and basic numeracy.

Communication skills and general knowledge

Children's communication skills and general knowledge based on broad developmental competencies and skills measured in the school context.

The AEDC is completed by teachers of children in their first year of full time school. It is important that all government, independent and Catholic schools participate in the census so that every community can receive data about their children.

Data is summarised in community profiles alongside other relevant demographic data to provide an overview of the contexts of children in each community.

This information can help communities understand the environments and experiences that are shaping children’s development in the early years.

Accessing AEDC data

Community results are easily accessed in the AEDC data explorer, a free interactive data visualisation tool.

Results are reported in maps, graphs and tables, available online and in Community profile reports. You can also read the guide to the AEDC data explorer.

Other data products by geographic area can be accessed via the AEDC data explorer. It also links to ABS contextual data and the Population Health Information Development Unit (PHIDU) Social Health Atlases.

Using AEDC data

When community organisations and local governments use the AEDC as a source of evidence this can contribute to improving children’s likelihood of developing on track and help build thriving communities.

Mount Gambier’s community tells their story of how they are taking action in response to their AEDC results and seeing positive change. There are many community stories like this from around Australia that can support others to think about how to reflect on and respond to their AEDC data. 

If you have an AEDC story to share, please email Education.AEDCTeam@sa.gov.au.

Use the AEDC as an evidence base to:

  • inform policy and planning such as strategic plans, regional public health plans
  • review services
  • allocate resources and assets
  • inform grant processes
  • inform collaborative approaches and community engagement
  • inform evaluations
  • measure progress over time.

The reporting, publication or analysis of AEDC data and results must be in accordance with the AEDC Data Guidelines.
