However, if one party forces the other party to sign an agreement in order to avoid responsibility, even if it is signed, it has no legal effect.

According to the agreement, if students bring knives to school, the school will not bear any responsibility in case of accidents. Careful analysis, in fact, both sides have responsibilities. Parents didn't check their children carefully before they arrived at school. Schools are also responsible for the poor supervision of accidents in schools. It is obviously unfair to shift the responsibility to one party, so it is also an invalid agreement.

Students who often skip classes explain the lack of family education, encourage them to make progress through repeated patient education, and abide by school rules step by step. Otherwise, you often play truant and your parents are unreasonable. They can report to the school and dismiss such students, so as not to cause trouble or loss to the school and teachers. Or, notify the security department, especially when cooking and at night. Signing an agreement with parents unilaterally is obviously ineffective.
