Since the 1990s, many OECD countries have expanded their early childhood services and developed more coherent and coordinated policies. Through this process, countries have adopted very different approaches to governing their early childhood systems. Drawing from findings of a 12-country comparative study, this article explores cross-national approaches to the governance of early childhood systems, as well as some possible implications for future policy development. The article discusses the roles of the national government, the local authorities, the private sector and other stakeholders, such as teachers and parents, in making key decisions about how the system operates in different countries. The article calls for empirical research on the effects of governance on the nature of policies and programmes for young children and their families in different nations. (Contains 3 notes.)
