There are many examples of collaborative action research being used to promote school change. Reflecting on evidence gathered as a result of collaborative inquiry led by a teacher in a primary school in Cyprus over a 3-year period, this paper examines what is involved in using such an approach within a centralised education system. In so doing, it exposes the social and political challenges involved, whilst at the same time throwing light on possibilities for overcoming these problems in order to facilitate school-led change. In this context, frequent staff changes presented particular barriers, and recent increases in migration into the country were seen to add further challenges, whilst at the same time opening up new possibilities for stimulating innovations through collaborative action research.
