Even in states where there is no specific law guaranteeing the right to attend graduation, students may still have legal recourse if they are prevented from attending. For example, students may be able to sue their school district for breach of contract or for violating their constitutional rights.
In addition to the legal issues involved, there are also ethical considerations to take into account when deciding whether or not to allow a student to attend graduation. For example, some people believe that it is unfair to punish a student for misbehavior by denying them the opportunity to graduate. Others believe that it is important to hold students accountable for their actions and that graduation is a privilege that must be earned.
Ultimately, the decision of whether or not to allow a student to attend graduation is a complex one that must be made on a case-by-case basis. There are no easy answers, and each school district must decide what is in the best interests of its students.
