The Foundation Phase (FP) is a statutory curriculum in each state school in Wales since 2008. The curriculum follows a developmentally appropriate pedagogy, and encourages children to engage by learning through experiences. The paper that follows is taken from a wider evaluation of the FP, commissioned by Welsh Government in 2012 and considers one of the seven areas of learning; Welsh language development. Results indicated no significant difference between how the Foundation Phase was implemented in Welsh and English medium schools. But, Welsh language development usually took place in whole-class morning activities (e.g. circle time) which doesn’t pair with the Welsh Government’s vision of intertwining the language in every aspect of the FP. The paper considers how schools and settings go about developing bilingual individuals, according to Welsh Government policy aspirations.
