To quantitatively evaluate the impact of peer assessment on academic performance across educational contexts compared to teacher assessment, self-assessment, and no assessment.
Conducted a meta-analysis synthesizing 54 experimental and quasi-experimental control group studies (k = 141) covering primary, secondary, and tertiary education across multiple subject domains.
Calculated standardized mean differences (Hedges' g) and ran meta-regressions evaluating potential moderators including feedback medium (online vs. offline), frequency, and education level.
Peer assessment produced an overall small-to-medium positive effect on academic performance across contexts (g = 0.31, p < .001).
Academic performance under peer assessment significantly outperformed no assessment (g = 0.31, p = .004) and teacher assessment (g = 0.28, p = .007), while showing no significant difference compared with self-assessment (g = 0.23, p = .209).
Meta-regressions showed that the beneficial effects of peer assessment were robust across varying educational levels, administration frequencies, and delivery formats.
