Over the last decades privatization policies have taken centre stage in many processes of educational reform globally. In Latin America, these policies have played an important role since the 1990s leading to an increasing participation of private agents in educational provision. The case of Uruguay stands out for having remained somehow apart from this privatization agenda. More recently, however, research has identified a significant shift in the discursive order especially driven by a series of new actors including think tanks and civil society organizations favourable to different forms of privatization. Building on case study methods and informed by a cultural political economy (CPE) approach this paper addresses two purposes. First, it attempts to explore possible explanations for the scarce development of the private sector in Uruguayan education. Second, it aims to characterize the discourses and strategies increasingly used by different actors to frame and promote policy ideas potentially leading to privatization policies. The study shows how a small but influential number of actors have become involved in the process of promoting ideas that seek to influence policymaking. Findings reveal how these actors frame school autonomy and accountability as policy solutions by means of different strategies of networking and knowledge mobilization.
