I do not think Maine has limits on how many comps a team can go to, but competitions are ONLY in the winter season, which begins around thanksgiving-ish. Various high schools host invitationals, and there's a Shriner competition that raises money for the Shriner's Children's Hospitals. There are no cheerleading company competitions in state, and I have never heard of a team going to them out of state so I doubt they are allowed. Each team competes in their conference championship (for my high school, it was the Southern Maine Activities Association) and then about a week later everyone goes to regionals (east/west). The top eight (I think) teams from each region continues on to states. The top three teams from each class at states goes on to New Englands. Nobody goes to nationals. The Maine Principal's Association recognizes winter cheerleading as a sport, but not fall cheerleading.
