Schools are risky places: the risk of a poor Ofsted report, the risk of sliding down league tables, the risk of teachers abusing children, the risk of teachers being falsely accused of abuse. As a result of risk anxiety and the ever-increasing sophistication of technology, the surveillance of teachers has proliferated, becoming a future-oriented pursuit to manage this risk. Drawing on the surveillance studies literature, this article attempts to theorise the surveillance of teachers. Firstly the article argues that there are three types of teacher surveillance: the vertical perpetuated by Ofsted and senior school leaders such as teaching observations and learning walks, but also students recording their teachers on mobile phones; horizontal surveillance enacted by peers in terms of concertive control, but also parental surveillance via online and offline networks; and, finally, intrapersonal surveillance embracing reflective practice, data reporting and self-policing proximity from children. The article then concludes by arguing that while surveillance in schools embraces the themes of modern surveillance in general, by doggedly retaining the proximal and the interpersonal, it should be considered a hybrid form between traditional and modern forms of surveillance.
