Student voice is, of course, fundamental -- who could argue against democracy? It is important that we do not return to a time where students were seen and not heard and positioned as subordinate figures but at the same time, do teachers suffer because of this democracy? Although student voice policies can represent positive developments, it would be naïve to be overly celebratory of pro-voice policies. This critical account focuses on some of the unsavoury ways that student voice can play out in schools: it can be used for surveillance; it can give rise to suspicion; and it can see dissenters stigmatised. Qualitative data generated through interviews with school staff are drawn on in this paper and researcher subjectivity is treated as a key asset as the author's student voice experiences at the coalface are first expounded in an autoethnographic account and then reflected in the interpretations and presentations of the interview data. What is coined the 'I(nterest) behind this research' means that student voice is not taken at face value or as an unquestionably positive initiative but something that can, even unintentionally, be more sinister.
