Children with facial injuries and disfigurements at school can take the following measures to claim compensation according to the actual situation. 1. Take the child to the hospital for treatment in time, and keep all medical records and expense documents. These evidences will help to prove the child's injury and the cost of treatment.

2, parents should get in touch with the school, understand the specific circumstances of the incident, and ask the school to investigate the matter. If the school fails to take effective measures to prevent such incidents, parents can ask the school to bear certain responsibilities.

3. According to the Tort Liability Law of People's Republic of China (PRC), the infringer shall bear the tort liability. Therefore, parents can claim compensation from the infringing classmates and their guardians. The amount of compensation should be comprehensively considered according to the child's injury, treatment costs, compensation for mental damage and other factors.

If both parties can't reach an agreement, parents can bring a lawsuit to the local people's court and ask the other party to bear the liability for compensation. In the process of litigation, parents should provide sufficient evidence to prove each other's fault and responsibility.
