This paper provides insights into teacher and school-based administrators' responses to policy demands for improved outcomes on high-stakes, standardised literacy and numeracy tests in Australia. Specifically, the research reveals the effects of the National Assessment Program -Literacy and Numeracy (NAPLAN), and associated policies, in the state of Queensland. Drawing suggestively across Michel Foucault's notions of disciplinary power and subjectivity, and Pierre Bourdieu's concept of social fields, the research utilises interviews with teachers and school-based administrators to reveal how high-stakes, standardised testing practices served to discursively constitute performative teacher subjectivities around issues of funding, teacher and school reputation and target-setting within what is described as the 'field of schooling practices'. The paper argues that the contestation evident within this field is also reflective and constitutive of more educative schooling discourses and practices, even as performative logics dominate.Introduction: Problematizing high-stakes assessment policy and practice This paper provides insights into the nature of teacher and school-based administrators' responses to policy demands for improved outcomes on high-stakes, standardised measures of achievement in literacy and numeracy in the Australian state of Queensland. Specifically, the research is concerned with school-level responses to the enactment of national standardised testing in literacy and numeracy via the National Assessment Program -Literacy and Numeracy (NAPLAN), and associated federal-state funding agreements designed to enhance students' literacy and numeracy outcomes. Drawing suggestively upon key concepts from the work of Foucault and Bourdieu, the research seeks to understand how the dominant discourses surrounding NAPLAN, as a vehicle for school accountability, constitute the performative subject of the teacher, and contribute to the various 'logics' that characterise schooling practice. Through interview data from teachers and school-based administrators, the paper reveals how national policies are enacted and mediated (i.e. practised) at the level of the school, and how these same policies discursively constitute the teacher as a performative subjectnot merely changing what teachers do, but also ultimately who teachers are (Ball, 2003).
