[영문]In this paper, I revisit some of the origins and more recent directions in practitioner research in social work, seeing it as a phenomenon that?rather than being special or narrowly associated with social work?manifests a pervasive cluster of concerns about good professional practice in contemporary society. Drawing on some general conclusions of a recent study of practitioner inquiry, I indicate ways in which the wider systems of which it is a part frequently hamstring the potential of such research to operate as more than a fringe operation?a ‘street market’ version of mainstream research. I outline four ways in which social workers, service users, agency managers, academics, government departments and universities should work to a transformative agenda for practitioner research?transformative for both practice and research. This will involve refashioning the interface between the methodology and methods of practice and research; generating practitioner research capacity; recognizing the subtlety and critical potential of a genuinely ‘practical’ agenda in practitioner research; and rescuing practitioner research from a simply technical information-providing function, that by-passes the challenge to promoting critical practice.
