Metacognition can assist students in improving poor examination (exam) performance. An exam wrapper is a metacognitive tool used to assess a student's thought processes and behavioral patterns during test-taking. The purpose of this study was to determine the effect of an exam wrapper tool used during one-to-one exam review sessions with faculty on prelicensure nursing students' subsequent exam performance. Paired t-tests and repeated measures ANOVA were used to compare undergraduate students' (n=91) exam scores before and after an exam review session with faculty in which the exam wrapper tool was used. Students who completed a one-to-one exam review session with faculty using the exam wrapper showed significant improvement in subsequent exam scores. Use of an exam wrapper tool as part of a one-to-one exam review session with faculty is a viable way to leverage metacognition to improve student exam performance.
