Australian Early Development Census

The Australian early development census (AEDC) is a population-based measure of how children in Australia have developed by the time they start their first year of full-time school.

About the 2021 data collection

Schools with kindergarten students in all schooling sectors participate in the census. Kindergarten teachers complete the Australian Version of the Early Development Instrument (AvEDI) for each child in their class, using a secure data entry system.

Teachers complete the instrument based on their knowledge and observations in their class. Children are not required to be present while teachers complete the AvEDI and schools participating in the collection receive funding for teacher relief time.

Since 2009 NSW has maintained a participation rate of over 95% at the state level in all collection cycles.

Further information about AEDC and the data collection process is available on the National AEDC website schools page. For further information or support for the 2021 AEDC data collection contact the AEDC Helpdesk on 1800 092 548 or email

AEDC NSW is hosting a weekly online information session to support schools during the data collection period. Sessions will be held each Wednesday from 5 May 2021 from 3:30-4:30 pm. Register for information session using the AEDC weekly information session registration form.
