Australian Early Development Census (AEDC)

The Australian Early Development Census (AEDC) is a nationwide data collection of early childhood development at the time children commence their first year of full-time school. The AEDC highlights what is working well and what needs to be improved or developed to support children and their families by providing evidence to support health, education and community policy and planning. The data is used by schools, communities, and governments to plan services and supports that give kids the best start at school.

The census is an Australian Government initiative, for which data is collected every three years. Data is reported at the national, state, community and school levels. Reports detail the number and percentage of children considered to be developmentally vulnerable, at risk or on track in each of the 5 AEDC domains, for example, emotional maturity.

School principals, who participated in the census, have received an email with a unique link to download their full AEDC School Profile Addendum. This addendum includes trend data for all collections in which the school participated, as well as state, territory and national results to enable comparison.
