 High school, college, and all-star competitive cheerleading follow different rules, in reflection of the varying levels at which the cheerleaders perform.Stunting rules and regulation for middle and high school cheerleaders are usually created and enforced by that particular state's athletics governing organization, with many following the American Association for Cheerleading Coaches and Advisors (AACCA) guidelines or the National Federation for High School Athletics (NFHS) handbook.They may include general safety rules about what types of surfaces the participants may perform stunts on (for example, some states don't allow stunts on hard surfaces like a track or basketball court) as well as more specific rules about exactly which stunts, pyramids, and tosses are and are not allowed.
