The purpose of this paper is to understand better the possibilities for practitioner research as a mode of educational inquiry that is yet to be legitimated within the academy. The paper maps the current state of play, and then moves on to consider what might yet be done to optimise its potential to contribute to rigorous new thinking about educational practice. Its exploration is in three parts: first, it seeks to account for the ambivalent status of practitioner research in the larger context of the modern university; second, it moves on from this account to argue both the value and the limitations of practitioner research as a contemporary mode of knowledge production in education; and finally, it suggests ways that practitioner research might be less delimited in terms of its capacities to produce knowledge that is useful to a wider range of stakeholders.
