In this paper, we address the work of teachers at the intersection of educational policy and professional discretion, by undertaking a conceptual reading of "Through Growth to Achievement: Report of the Review to Achieve Educational Excellence in Australian Schools," and examining how the report conceptualises teacher practice. Drawing on the Bourdieusian notion of regulated improvisation, the study explores the constraints of pedagogical practices as conceptualised by influential policy reports of this kind, highlighting the paradoxical expectations of the report on teachers whose situational awareness of classrooms is curtailed through regulation. The study examines the tension between teacher autonomy and constraints, negating important considerations to temporalities of learning. The central contribution of the paper is a conceptual understanding of how policy drivers position teacher expertise through standardisation, compliance and performance, a concern not unique only to the Australian context of educational policy, nor schooling.
