Abstract:
Assessing student mastery is often done by using exams. Inevitably, some students will complete remediation, which may include exam retakes. This method provides students an additional opportunity to take an exam that assesses the same objectives as the original exam, while using different questions. Although this form of remediation increases exam scores, it is also possible that students who prepare for an exam retake adversely affect preparation for an upcoming exam. Therefore, the purpose of this study was to determine whether studying for and taking an exam retake affected preparation for the next exam. We hypothesized that students who completed an exam retake would have lower than expected scores on their next exam. This study utilized data collected over five semesters from 467 students enrolled in a 200-level introductory human physiology class; 159 students (34.0%) completed at least one exam retake. Students who retook an exam increased their original exam score by 6.1% (SD 13.9). These findings suggest that retaking an exam leads to better outcomes, which could be explained by students improving their study habits or test-taking skills, which would help them perform better on future exams.NEW & NOTEWORTHY Exam retakes provide students with an additional opportunity to demonstrate mastery of learning objectives. However, this preparation might adversely affect performance on subsequent exams. This study suggests that students who choose to prepare for and take an exam retake not only improve their original exam score but show a larger improvement on subsequent exam performance than those students who did not take an exam retake.
