In this article, we argue for a study of educational administration centered on an "ontology of practices." This is an initial proposal for thinking about and conceptualizing practices in educational administration. To do this, first, we explore how practices are constituted and how they configure the social realities of practitioners. Second, we explore what an ontology of practices has to offer for our understanding of organizations. Third, we examine how an ontology of practices might inform our understandings of leadership in educational organizations, and we conclude by exploring some implications of an ontology of practices for the study of educational administration.
