The WKF has developed common rules governing all styles. The national WKF organizations coordinate with their respective National Olympic Committees.
USA National Karate-do Federation
The Amateur Sports Act of 1978 enabled the governance of sports in the US by organizations other than the AAU. This act made each sport set up its own National governing body (NGB). Each of these governing bodies would be part of the United States Olympic Committee, but would not be run by the Committee. Thus, The USA Karate Federation was born.
