Since our 1998 review of research on classroom assessment and learning was published, we have contributed to theorising formative assessment, but recognise that this work is incomplete. In this paper, we take up a suggestion by Perrenoud that any theory of formative assessment must be embedded within a wider theoretical field, specifically, within…

In this article, Dylan William states that the central claim in Baird, et al.'s piece is that if theories of assessment take into account theories of learning, assessments will somehow be more valid, and some of the more egregious effects of assessment on learning will be ameliorated. William responds to this claim by arguing that it seems…

The idea that assessment is intrinsic to effective instruction is traced from early experiments in the individualization of learning through the work of Benjamin Bloom to reviews of the impact of feedback on learners in classrooms. While many of these reviews detailed the adverse impact of assessment on learning, they also indicated that under…

According to Dylan Wiliam, the traditional classroom practice in which a teacher asks a question, students raise their hands, and the teacher calls on a volunteer does not actually provide much useful information--and it may even impede learning. When teachers ask questions in this way, they're only engaging the most confident students in the…

According to author Dylan Wiliam, because lessons never go exactly as planned, teachers should build plan B into plan A. This involves designing a lesson with a "hinge" somewhere in the middle and using specific kinds of questions--what he calls hinge questions--to quickly assess students' understanding of a concept before moving on.…

Whilst many definitions of formative assessment have been offered, there is no clear rationale to define and delimit it within broader theories of pedagogy. This paper aims to offer such a rationale, within a framework which can also unify the diverse set of practices which have been described as formative. The analysis is used to relate formative…

This September 2010 article is a reprint of the original October 1998 article. Few reform initiatives focus on what goes on in the "black box" of the classroom, on what really happens in the interaction between teachers and students. This article is about the inside of the black box. The authors focus on one aspect of teaching: formative…

Defines a cycle of assessment and action, and a continuum from formative to summative assessments. Illustrates problems caused when one assessment must serve both formative and summative functions. Argues that separating the collection of evidence from its interpretation, or the interpretation of evidence from consequent action, helps alleviate…

In their widely read article "Inside the Black Box," the authors demonstrated that improving formative assessment raises student achievement. Now in this article, they and their colleagues report on a follow-up project that has helped teachers change their practice and students change their behavior so that everyone shares responsibility…

While it is generally acknowledged that increased use of formative assessment (or assessment for learning) leads to higher quality learning, it is often claimed that the pressure in schools to improve the results achieved by students in externally-set tests and examinations precludes its use. This paper reports on the achievement of secondary…

Firm evidence shows that formative assessment is an essential ingredient of classroom work and that its development can raise achievement standards. Achieving this goal demands a four-point scheme for teacher development: learning from development, a slow, yet steady dissemination process, reduction of obstacles, and substantive research efforts.…

The authors trace the development of the King's Formative Assessment Programme from its origins in diagnostic testing in the 1970s, through the graded assessment movement in the 1980s, to the present day. In doing so, they discuss the practical issues involved in reviewing research and outline the strategies that were used to try to communicate…

In this paper, the authors first give a brief account of their work with teachers to develop formative assessment practices, including a brief outline of the quantitative results and the impact of formative assessment project. They give a full account of the changes in classroom practice that the project schools developed, together with some…

This article describes changes in the practice of two teachers, observed over an 18-month period, who were participating in a study intended to support teachers in developing their use of assessment in support of learning. The design of the intervention allowed each teacher to choose for themselves which aspects of their practice to develop.…
