The Family Medicine Clinical Science Mastery Series (CSMS) self-assessments, which are made up of former Family Medicine NBME examination questions, became available in September 2017. They provide students with realistic practice questions and immediate performance feedback. To further assess the utility of various study tools available to our students, this study investigated the impact of the CSMS self-assessments for family medicine on the NBME family medicine subject examination performance. Methods: Data analysis was conducted to compare student performance on the end-of-rotation NBME Family Medicine Clinical Subject Examination before and after the introduction of the CSMS family medicine self-assessments. The effect size was measured using a Cohen d analysis. We conducted an independent t-test analysis to determine the effect the NBME Family Medicine CSMS self-assessments had on end-of-rotation clinical subject examination scores. Results: The analysis revealed statistically significant improvement in students’ clinical subject examination scores after the release of the CSMS in September 2017 (n=90) compared to the students’ scores prior to the availability of the CSMS (n=95). Conclusions: Student scores improved with the introduction of the NBME CSMS family medicine self-assessment. These results support recommending student use of the CSMS as a study tool for their end-of-clerkship NBME subject examinations.}, URL = {https://journals.stfm.org//familymedicine/2019/september/minor-2018-0513/}, eprint = {https://journals.stfm.org//media/2568/minor-2018-0513.pdf}, }
