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 AEDC is held every three years, with the 2015 AEDC data collection being the third collection. The census involves teachers of children in their first year of full-time school completing a research tool, the Australian version of the Early Development Instrument. The Instrument collects data relating to five key areas of early childhood development referred to as ‘domains’, these include:
- Physical health and well being
- Social competence
- Emotional maturity
- Language and cognitive skills
- Communication skills and general knowledge
The AEDC domains have been shown to predict later health, wellbeing and academic success.
