Educational reform in Australia recognizes the need for an effective teacher evaluation system but has fallen short of actually prescribing one. Current practice does not align to policy intent, with teacher evaluation largely an exercise in compliance around performance management as opposed to a process that promotes evaluative thinking, continuous improvement and connection to student outcomes. The recent introduction of the Australian Professional Standards for Teaching has gone some way to providing a common language and the idea of a nationally acceptable pathway for teacher development and performance. Nonetheless, two things are missing in the Australian context: the privileging of developing evaluative mindsets in teachers and school leaders and the tools and methods that provide the 'how' of evaluation and support this thinking. Situated against a period of reform in Australia's diverse federal and multi-sectoral education system, this article first provides an analytical review of the Australian approach to teacher evaluation. It then presents two innovative approaches that support the process of evaluation and the broader information needs of an evaluation system while developing teachers' and school leaders' evaluative thinking which engages evidence-informed change and ultimately more sustainable outcomes for the education system.
