Improving student performance on exams is a key issue that many psychology instructors face in their classrooms. One potentially easy to deploy option for improving student performance is an exam wrapper. In this article, I detail two studies that compared exam wrappers to a control condition (a previous semester in Study 1 and a within course control condition in Study 2). Both studies found notable improvements in student exam performance above what is typically seen in the course. This suggests that the exam wrapper is an easy-to-employ tool for your students to use to improve their test preparation and performance.
