A growing body of literature argues that integrated services, where a range of professionals including early childhood professionals work together in teams, offer a potentially highly effective strategy for providing families with access to a range of services in a seamless "joined-up" way. Some have cautioned, however, that early childhood pedagogy and professionals within such hybrid services are in danger of being marginalised. Despite the growing literature suggesting strategies for supporting inter-professional teamwork in integrated services, there are relatively few empirical studies of how such teams operate in practice in Australian contexts. This paper reports on findings from a project funded by the "Professional Support Coordinators Alliance" (PSCA), that investigated, through a survey (n = 25) and case studies (n = 10), the experiences of professionals in integrated services across Australia and their perspectives on factors that contribute to the success of these services and to inter-professional working. The findings indicate that the early childhood professionals who participated in the study are generally optimistic about these services and about working in inter-professional teams.
