The U.S. Training Federation (USTF) is believed to be the oldest existing USA-based federation. CwbyJnky opened its doors on March 5th, 2002, though he has since retired from his post as president and made way for acting president GlennCraven. The federation has only about 180 members, but despite this low enrollment most US managers consider it to be the most important federation for National Team coaches and a primary reason for the USA's national team success. The US Training Federation generally endorses a candidate in each US national coach election, though they failed to do so in the most recent U-20 election. Enrollment is open to all US managers who support the US by training home-born players, though this is a fairly loose requirement.
