This article uses the developmental systems approach, an approach developed by M. Guralnick (2001), with an aim to assess and evaluate early childhood intervention (ECI) practices in Australia. The author explores the Australian national context of ECI and its complexities and conclude with recommendations to address (a) the possibility of a national policy and practice framework specifically developed for ECI, (b) information and knowledge supports available for families and communities caring for a child with disability or developmental delay, and (c) inclusion strategies that would impact on the quality of children and families' experiences in mainstream settings.
