New approaches to assessment have emerged over the past few years, out of a variety of overlapping international debates about the purposes and methods of assessment and about its impact on teaching and learning. Examining the data from an ethnographic study on the relation between teachers' beliefs and their practices in an assessment reform, this paper focuses on teachers' use of metaphors in their accounts of their work. It brings to light the crucial role of teachers in mediating and bringing about changes envisaged in the new assessment reforms. The implications of the findings for the professional development of teachers are discussed.[Copyright of Educational Review is the property of Routledge.
