Contemporary currents in school leadership increasingly focus on collaboration and participation. In Sweden, notions of “communal pedagogical leadership” emphasize teachers’ roles in shaping the desired school, introducing Collaborative Professional Learning (CPL) as an organizational necessity. This article provides a governmentality analysis of CPL manuals from 2019 to 2022, exploring the rationalities employed in its framework and how subjects are governed by it. The analysis reveals that CPL establishes new conditions for governing subjects within schools. Through CPL, school leadership assumes the role of fostering a collective unity and instilling a desire for collaboration and change, redirecting the aim of interventions to specifically target school cultures and teacher attitudes. In emphasizing teachers’ commitment to collective unity as the primary measure of progress, CPL institutes a mode of governing mobilized through subjects’ self-governing of their will to collaboration, thereby altering the meaning of leadership in contemporary school organizations.
