The Australian Early Development Index (AEDI) measures how young children are developing in defined Australian 'communities'. It provides a population measure of children's development at the time they start primary school. The primary aim of the AEDI is to provide data to help communities in the development and reorientation of services and systems to enable them to improve the health and wellbeing of young children.

The AEDI is based on the scores from a teacher-completed checklist, with over 100 questions covering five developmental domains: physical health and well-being, social competence, emotional maturity, language and cognitive skills, and communication skills and general knowledge. AEDI results relate to the children's area of residence. It is designed for use with whole populations of children within a geographic area. The AEDI is analysed at the local community level (i.e. suburb or small area locality).


The AEDI population is all children in the first year of full-time primary schooling within a community or a geographic area.
