There is a global movement of education reform, informed by a neoliberal agenda, emphasising continuous improvement and accountability through performance measurements, surveillance and monitoring. This puts local school actors under constant gaze and endless pressure to perform. This article uses a Swedish state-initiated school improvement programme, Co-operation for the Best School Possible (CBS), to investigate how power is exercised within the programme and to discuss possible implications for the local actors. A theoretical model based on Foucault's power modes of sovereign, disciplinary and pastoral power as well as governmentality is used. Empirically, the article builds on a case study from a municipality participating in CBS. The analysis takes impression of Jackson and Mazzei's "thinking with theory". The CBS programme illustrates the widespread and multifaceted nature of power in educational governance, prompting local actors to internalise norms, self-regulate, and continuously evaluate their practices. This study highlights the importance of understanding the interplay of different power modes in shaping educational practices and the professional lives of local school actors. This article has contributed to questioning the common sensical, and it has made the exercises of power recognisable through the use of Foucault's concepts.
