One of the goals of every educator, parent, and student is to prevent bullying from happening. Anti-bullying laws are one prevention strategy that can change social norms. When researchers in the United States began studying bullying in the early 1990s, there were only a few anti-bullying laws and policies. Now, every state and most U.S. commonwealths and territories have a law or policy on bullying. Although no federal policy exists specific to bullying, other federal laws provide certain protections.
