In recent decades children's rights to exercise choice in educational settings have slowly gained currency. Children's rights advocates highlight the role of choice in empowering children to become critical and productive citizens. However, in this paper, the role of choice in interactions between teachers and students is problematised. Using Foucault's notion of governmentality, the paper explores 15 teachers' use of choice in classrooms and considers how 'student choice' can, far from empowering children, be used as a way of reinforcing extant adult-child power relations. The paper argues that students are often responsibilised to exercise choice wisely in order that they find themselves in a position in which they can enjoy everyday classroom privileges disseminated by the educator. When used this in way, the strategy of affording students 'choice' can frame students' transgressions as individual failings to conform. The paper concludes that practitioners who advocate children's rights need to reflect on the relationship between notions of choice and institutional power relations in order to ensure choice is used in a way that leaves space for power relations to be challenged by the students being asked to 'choose'.
