This article uses the history of debates over the US Head Start programme (1965), Early Head Start (1994) and the UK Sure Start initiative (1998), as a window on to policy transfer. In all the three, the aim was that early intervention could offer a means of boosting children's educational attainment and of countering the wider effects of poverty on development. Nevertheless, there were also important differences between them. The first part of the article looks at UK responses to Head Start, the second at Early Head Start and the creation and subsequent direction taken by Sure Start. In the Conclusion, we sum up the arguments relating to Head Start and Sure Start and offer some broader reflections on policy transfer.
