1, the school is not at fault. First of all, the school physical education class and this training course are in compliance with laws and regulations. Secondly, the teacher explained the essentials of action first. Secondly, under the protection of the teacher, it shows that the teacher has no fault in this training. Finally, according to your description, "the plaintiff did a handstand with the help of the teacher and then did a forward roll", and the word "himself" means that it is the students' own fault.

2. Not liable for compensation. According to Article 38 of China's Tort Liability Law, kindergartens, schools or other educational institutions shall bear the responsibility if a person without capacity for civil conduct suffers personal injury during his study and life, but those who can prove that they have fulfilled their educational management responsibilities shall not bear the responsibility. It can be seen that if the principle of "presumption of fault" is adopted, the school has no fault and will not be liable for compensation.
