Be Aware of Policies and Laws
As a parent, one of the best things you can do is learn your school district’s policies on bullying. Get a copy of the district handbook and refer to it whenever your child reports that someone in school has bullied him.
If an incident takes place off-campus, it is not an issue for the school (and most schools will tell you that). They will say, “There is nothing we can do," and they are right.
However, there IS something the police can do. Legally, when bullying lands off-campus, it becomes the jurisdiction of local law enforcement. You can report anything serious, such as harassment, threatening, physically attacking or other behaviors, to law enforcement for action. This includes acts of cyberbullying, including instant messaging abuse, online inappropriate communications and many others.
It is also notable that much anti-bullying legislation is instigated at the state level, so it is important to know your state laws regarding bullying.
