Australian Early Development Census

Australian Early Development Census logo (a sylised adult and child in green, blue, red, and yellow), followed by the words An Australian Government Initiative.

The Australian Early Development Census (AEDC) measures how young 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. This data provides evidence to support health, education and community policy and planning.

To date, the development of over 850,000 children living in Australia has been measured across three collections, including more than 54,000 from South Australia.

The fourth AEDC data collection took place from 1 May 2018 to 3 August 2018.

Access the AEDC community data

National, state and community AEDC data for the 2018 collection will be released in March 2019.

A range of data products are available from the AEDC website, including national reports, community profiles and community data in map, graph and table format for export.

Australia continues to be a world-leader in the measurement of early childhood development with the 2015 collection capturing data on more than 300,000 across Australia across all schooling sectors, including more than 19,600 from South Australia or 96.4% of eligible children across all schooling sectors.

Access the AEDC school data

AEDC school data for 2018 is available to schools with six or more reception children that participated in the 2018 AEDC data collection. The AEDC school profiles provide an overview of school results and include useful information on interpreting, using and sharing AEDC school data.

Principals at participating schools receive an email link to download their de-identified data at the end of each collection year. The AEDC school profiles can also be emailed direct to school principals by contacting the AEDC helpdesk on 1800 092 548 or helpdesk [at] aedc.gov.au or the DECD.AEDCTeam [at] sa.gov.au (state AEDC coordinator).

What the AEDC measures

The AEDC measures how children are developing in five key areas known as 'domains':

  • physical health and well being
  • social competence
  • emotional maturity
  • language and cognitive skills (school-based)
  • communication skills and general knowledge.

Using the AEDC data

The AEDC data provides vital information for planning and community collaboration to support children's early development, learning and transition to school.

The AEDC data can help communities, schools and preschools to:

  • understand the local levels of developmental vulnerability and reflect on the factors that might be influencing this
  • implement programs and services for children in the community to support early child development
  • plan and support children's successful transition to school
  • form collaborative partnerships to support children and their families.


A new range of resources tailored for schools and early childhood education and care settings are available below. The suite of materials for leaders and teachers highlights connections between the AEDC domains and the National Quality Standard, Early Years Learning Framework, Australian Curriculum and Australian Professional Standards for Teachers (AITSL).

This package of materials has been developed by a collaboration led by the Western Australia Department of Education, with the Association of Independent Schools of Western Australia, Catholic Education Western Australia, the South Australian Department for Education, the New South Wales Department of Education and the Telethon Kids Institute.
