The fifth national Australian Early Development Census (AEDC) data collection took place from 4 May to 25 June 2021.
Conducted every 3 years, the AEDC is the most comprehensive collection of its kind in the world. The information gained from the census helps to shape the future and wellbeing of our children by providing evidence to support education, health and community policy and planning.
In November 2021 confidential AEDC School Profiles were made available for all participating schools with 6 or more Prep student enrolments at the time of the census.
2021 AEDC community data is now available and School Profiles have been replaced by School Profile Addendums containing state and national data comparisons. These will be available to school principals via a secure email link and also in OneSchool, under the ‘Reports’ tab.

What the AEDC data means for schools
The AEDC collection provides vital information for school planning and community collaboration to support children's early learning, development and transition to school.
The AEDC data can help schools to:
- plan and support children's
successful transition to school
- support student learning, wellbeing and inform school improvement planning
- raise awareness of the importance of children's early years
- implement programs and services for children in the community to support early child development
- act as a platform to forge collaborative community partnerships.

school resources and
Queensland community stories to assist with understanding AEDC data and how it can be used.
About the AEDC
Australian Early Development Census (AEDC) is a nationwide data collection that occurs every 3 years.
The AEDC measures how children are developing as they transition into their first year of school based on
5 key areas known as 'domains': Physical health and wellbeing, Social competence, Emotional maturity, Language and cognitive skills (school-based), and Communication skills and general knowledge.
Physical health and wellbeing
Children's physical readiness for the school day, physical independence and gross and fine motor skills.
children's overall social competence, responsibility and respect, approach to learning and readiness to explore new things.
Children's prosocial and helping behaviours and absence of anxious and fearful behaviour, aggressive behaviour and hyperactivity and inattention.
Language and cognitive skills (school-based)
Children's basic literacy, interest in literacy, numeracy and memory, advanced literacy and basic numeracy.
Communication skills and general knowledge
Children's communication skills and general knowledge base on broad developmental competencies and skills measured in the school context.
Information and resources for schools and Early Childhood Education and Care services are available on
