The goal of this study was to explore longitudinal associations between peer victimization and academic achievement in Chinese children. Participants were N = 805 3rd-grade students (486 boys, 319 girls; M[subscript age] = 9.5 years, SD = 3 months) attending primary schools in Shanghai, People's Republic of China. At Time 1 and Time 2 (2 years later), peers nominated classmates who were victims of peer maltreatment using the Chinese version of the "Revised Class Play" (Chen, Rubin, & Sun, 1992), and teachers rated students' academic achievement. Among the results, peer victimization was negatively related to academic achievement at both time points. Also, peer victimization and academic achievement displayed considerable stability across the 2 years. Results from cross-lagged hierarchical analyses demonstrated that peer victimization at Grade 3 predicted lower academic achievement at Grade 5. However, academic achievement at Grade 3 was not predictive of peer victimization at Grade 5. These results suggest that peer victimization appears to function more as a precursor rather than a consequence of lower academic achievement. Results are discussed in terms of the cross-cultural similarities in the links between peer maltreatment and academic achievement and their educational implications.
