This paper is firmly grounded in the position that engaging with students' voices in schools is central to the development of inclusive practices. It explores the tensions that can be created when efforts are made to engage with students' voices in relation to their experiences of learning and teaching. An example from a three-year research and development project, which worked alongside teachers to use students' voices as a way of developing inclusive practices, is used to illustrate these tensions. This project, though showing that students' voices can be a powerful means for understanding learning and teaching in schools, also encountered challenges with these processes. This paper focuses on the experiences of one secondary school which (possibly inadvertently) subverted and undermined students' voice initiatives and explores the potential negative impacts of this on individual students, on students as a whole, and on teacher development. By doing this, suggestions as to how such tensions can be avoided in schools are offered, with the aim being to allow a genuine engagement with the views of students.
