Formative Versus Summative Assessment in Medical Education: A Systematic Review and Meta-analysis

Background: Assessment methods are fundamental components of medical education for evaluating academic achievement, clinical competency, and professional development. Formative assessment focuses on continuous feedback and learning improvement, whereas summative assessment evaluates final competency and academic outcomes. The comparative effectiveness of these assessment strategies in medical training remains an area of ongoing educational research.

Objective: To systematically compare formative and summative assessment methods in undergraduate and postgraduate medical education.

Methods: A systematic review and meta-analysis was conducted according to PRISMA 2020 guidelines [10]. PubMed, Embase, Scopus, Web of Science, and Cochrane Library databases were searched from inception to December 2025. Studies comparing formative and summative assessment strategies among medical trainees were included. Primary outcomes included academic performance, clinical competency, learner engagement, and student satisfaction. Random-effects meta-analysis was performed using standardized mean differences (SMDs) and odds ratios (ORs) with 95% confidence intervals (CIs).

Results: Twenty-two studies involving 6,814 medical trainees were included. Formative assessment demonstrated significantly improved academic performance compared with summative assessment alone (SMD 0.48; 95% CI: 0.31–0.65; p<0.001). Clinical competency scores were significantly higher among students exposed to formative assessment strategies (SMD 0.53; 95% CI: 0.35–0.71). Students undergoing formative assessment also demonstrated improved learner engagement, reflective learning behavior, and greater student satisfaction. Summative assessment remained effective for standardized competency evaluation but was associated with increased examination-related stress and anxiety.

Conclusion: Formative assessment is associated with superior academic performance, clinical competency, learner engagement, and student satisfaction compared with summative assessment alone in medical training. Integration of structured formative assessment strategies alongside summative evaluation may optimize competency-based medical education.
