In this paper, I draw on a study of school leaders' experiences of inspection to argue that repeated changes to school inspection policy in England constitute a post-panoptic regime. Thinking with and against Foucault, I elaborate post-panopticism, here characterised by: subjects' visibility; "fuzzy" norms; the exposure of subjects' failure to comply; the disruption of identity-constituting fabrications; its dependence on external "experts"; and its neo-conservative devalorisation of the interests of the socio-economically disadvantaged. The paper argues that post-panopticism depends on subjects having become disciplined through panopticism, whose apparatus it employs, and reveals the state's explicit exercise of power.
