States and provinces across the United States and Canada each have their own local competitions from which the winning high school team earns the privilege of representing their state/province at the North American Envirothon Competition, held each summer in a different U.S. state or Canadian province. In regions with a considerable number of teams, competitions on subdivision, county, regional, or district levels are also held. Teams must win these intermediary competitions in order to move on to the state/province levels. At the North American Competition, teams that rank first through tenth receive prizes and scholarships of various values.
