This paper explores different conceptions of responsibility within and beyond neoliberal frames. Such exploration draws on the experiences and accounts of "Ashleigh," a head teacher at a primary school in outer London that is part of an academy chain. Ashleigh and her school were key participants in a study that explored matters of accountability, performativity and equity. Through the presentation of interview data gathered from Ashleigh and six of her staff, the paper theorises ways of being a head teacher as aligning with the responsible neoliberal subject--a self-determined and rational actor who readily takes up the modes of regulation and measurement expected of them. It also highlights how this subjectivity sits within and alongside relations of care and concern for the welfare of students and teachers. The paper critically examines the implications of these different conceptions of responsibility in their production of different versions of professionalism. It also seeks to broaden current scholarly understandings of the responsible neoliberal subject and provide a counter-story to the tendency within public and political discourse for responsibility to be constructed in largely neoliberal terms.
