The United States Kuo Shu Federation (U.S.K.S.F.) is a rapidly growing nonprofit organization that promotes friendship, unity, physical fitness, harmony, ethics, and peace around the world through the principles of Chinese Kuoshu (also known as Kung-Fu). The U.S.K.S.F. consists of a board of directors representing martial arts organizations from across the U.S. Through this national network, the international standards for certification of judges, referees, and instructors are promulgated, and a new grading (ranking) system based on standards developed by The World Kuo Shu Federation; which is the first world organization to have adopted such a ranking system. Additionally, each successive national tournament held in the U.S. helps to raise the level of competition in preparation for the periodic world competitions as well as to expand the interest in Kuoshu across generations.
