Results from 2009, 2012, 2015, 2018, 2021 and 2024 data collections
The Australian Early Development Census (AEDC) is a measure of young children’s development in their first year of full-time school and is collected by teachers across all school sectors.
The sixth wave of AEDC was collected in 2024, the first in 2009.
The AEDC data shows us how well children are faring and monitors developmental vulnerability over time. We can unpack these results with communities to understand what may be driving change.
You can download a PDF summary of the results.
More than 67,000 children participated in the AEDC in Victoria in 2024.
Over 288,000 children participated in the AEDC in Australia in 2024.
