校园欺凌是指学生或者教师在校园及其合理辐射范围对处在相对弱势地位学生实施的反复性肢体暴力、语言暴力、网络暴力等对其身体或者情感产生伤害的行为。教育机构在满足《侵权责任法》38及39条的规定条件时承担责任，可基于受害者存在过错免责。作为教育机构责任构成之核心范畴，教育、管理职责应结合法律规定、当事人约定及一般注意义务综合认定。虽网络欺凌突破了传统欺凌方式的范畴，但教育机构仍应对发生于校内的网络欺凌及实质侵害校园秩序的校外网络欺凌承担责任。受害者自杀不必然阻断教育机构行为与自杀后果的因果关系，亦不必然成为教育机构拒绝承担责任的免责事由。

School bullying refers to a phenomenon that a student is repeatedly exposed to physical violence, verbal violence, cyber violence from stronger students or teachers on campus, which inflict harm to his/her bodies or emotions.Educational institutions are liable when they meet the conditions specified in Articles 38 and 39 of the Tort Liability Act. They may be exempted from liability due to the fault of the victim. As the core category of responsibility of educational institutions，the duty for education and management should be confirmed by the legal provisions, the parties' agreements, and general duty of care. Cyberbullying has broken through the scope of traditional bullying, but educational institutions still have to take responsibility for on-campus cyberbullying and off-campus cyberbullying which materially and substantially interferswith therequirements of appropriate discipline in the operation of the school. Victim suicide does not necessarily block the causal relationship between educational institutions' behavior and suicidal consequences, nor does it necessarily constitute an exemption for educational institutions to refuse to accept responsibility.
