The is a national population-based measure of how young children have developed by the time they start their first year of full-time school. It is the only measure of its kind in Australia, and Australia is the only country conducting this census nationally.
The AEDC highlights what needs to be improved to support children and their families. It also helps communities know how their children are progressing.
Nearly a quarter (23.8%) of ºÚÁϳԹÏn reception students had 1 or more developmental vulnerabilities in 2021, a 0.1 percentage point decrease since 2018. The 2021 data also shows an increase of 0.5 percentage point to 53.7% of children developmentally on track across the 5 AEDC domains (physical health and wellbeing, social competence, emotional maturity, language and cognitive skills (school-based), communication skills and general knowledge).
Despite the slight changes in the 2021 collection results, the proportion of our children who are developmentally vulnerable has been on the rise since 2009, as opposed to most other states where vulnerability has decreased. Developmental vulnerability in ºÚÁÏ³Ô¹Ï has now spread across all socioeconomic levels and geographic areas indicating further work is needed to get the balance between universal and targeted approaches right.
ºÚÁϳԹϒs 2021 AEDC results are available in 4 snapshots and a map, providing data and key findings in more detail.

In 2019 the ºÚÁϳԹÏn Child Development Council established the to monitor, track and report the outcomes of our state’s children and young people (birth to 18 years) in 5 dimensions: health, safety, wellbeing, education and citizenship. The Child Development Council’s specifically highlighted these AEDC trends in ºÚÁϳԹÏ. Find out more about the on their website.
Research into how we can support children to be developmentally on track on all 5 AEDC domains by the time they start school is important. It helps all levels of government, community and education sectors with planning, policy, service and program decisions.

How the data is collected
Data is collected every 3 years by teachers of children in their first year of full-time school, in schools across Australia. Five sets of data are now available from 2009, 2012, 2015, 2018 and 2021. Around 300,000 children take part in each collection. This forms a robust evidence base to inform research.
The data is collected using the Australian version of the . This is made up of around 100 tested and validated questions.
Using AEDC data in research
You can use AEDC data with other resources to plan and evaluate ways to improve early childhood development outcomes.
Uses of the AEDC data include:
- research about early childhood development
- informing schools of ways to improve their practices
- informing the development and evaluation of national, state and community priorities, programs and policies, through statistical analysis and publication of information about the early development of children.
