The reliability, validity, and utility of self-assessment

Abstract

Despite widespread use of self-assessment, teachers have doubts about the value and accuracy of the technique. This article reviews research evidence on student self-assessment, finding that (1) self-assessment produces consistent results across items, tasks, and short time periods; (2) self-assessment provides information about student achievement that corresponds only in part to the information generated by teacher assessments; (3) self-assessment contributes to higher student achievement and improved behavior. The central finding of this review is that (4) the strengths of self-assessment can be enhanced through training students how to assess their work and each of the weaknesses of the approach (including inflation of grades) can be reduced through teacher action.
