The AEDC is implemented every three years. We now have data from 2009, 2012, 2015, 2018, and 2021. The sixth collection will take place in 2024.
We are grateful to all those teachers and schools that contributed to the AEDC data collection. Because of their commitment to the AEDC we are able to build a picture of Victorian children’s development over time.
The AEDC is a population measure of how young children are developing across Australia as they begin school. It measures children’s development across five domains:
- physical health and wellbeing
- social competencies
- emotional maturity
- language and cognitive skills (school-based)
- communication skills and general knowledge.
AEDC results are reported as proportions of children who are considered to be:
- ‘on track’ - that is, doing well
- ‘developmentally vulnerable’ on one or more domain – those children who may be at risk of not doing well in life
- 'developmentally vulnerable’ on two or more domains – those children who may not be ready to achieve success at school, and/or who do not have the basic skills in place.
The AEDC is a key tool in school, early years and community planning, research and policymaking across Victoria and nationally.
The AEDC is completed by school teachers in children's first year of school.
