While recognition of the need to involve parents in the life of the school grows in public policy, anxiety continues at the intervention of 'the angry parent'. This paper seeks to develop understanding of this communicative action and apply it to a study of parental voice in schools that identified a number of expressions of 'storming'. The paper argues that these occasions were reactions to events in school and the underlying 'performative attitude' of parents in their communications was to seek mutual understanding. The disposition of the school, however, while enabling communicative understanding on some concerns (such as welfare) was less amenable to negotiating agreement on issues it regarded as core professional practice (such as control of the learning and teaching process). Parental cultural capital, nevertheless, could exercise a space of influence.
