This paper analyzes the performance of China’s anti-bullying efforts with the data on school bullying in the Program for International Student Assessment (PISA) 2015 and PISA 2018. It is found that China has fully demonstrated its high performance in anti-bullying actions with all three key performance indicators dropping dramatically, namely the prevalence of bullying, the index of exposure to bullying, and the percentage of frequently bullied students. Further, from the perspectives of personal characteristics and school features, two rounds of PISA data are adopted to make the longitudinal diachronic comparison and the cross-national horizontal comparison, followed by the analysis of the occurrence and development patterns of school bullying. Five suggestions are put forward for the deployment of China’s anti-bullying action plan.
