Since 2004 the Australian Early Development Index (AEDI) has been completed in 54 Australian communities over seven states and territories on more than 30,000 children. A concurrent systematic evaluation of community implementation and use of the AEDI was undertaken that included both a process and impact component. The purpose of this paper is to discuss the evaluation findings between 2004 and 2006. Results have shown there are a number of barriers and facilitators for communities in implementing the AEDI, disseminating results, and planning for community actions. The evaluation findings indicate AEDI implementation helps raise awareness of the importance of early childhood development, assists communities to work more collaboratively and to strategically plan actions to work towards improving outcomes for children.
