The Impact of Eliminating Backward Navigation on Computerized Exam Scores and Completion Time

Abstract

Objective. Computer based testing has become a standard at many colleges of pharmacy. Restricting an exam takers ability to revisit questions previously answered (elimination of backward navigation), is an option available in some testing software. Our objective was to determine whether elimination of backward navigation resulted in changes in examination score or time to complete the exam.

Methods. Six exams administered in courses that eliminated backward navigation were compared to exams given the previous year where backwards navigation was allowed. The primary comparison of interest was change in a subset of identical questions included on both exams. Secondary outcomes included change in total exam score and completion time. The exam data used in this research were obtained using ExamSoft testing software.

Results. No statistically significant reductions in exam scores were observed. Average time spent on a question was significantly reduced on 2 of the 6 exams.

Conclusion. No adverse effect on scores or testing time was found across 3 years of the didactic pharmacy curriculum.
