Professional Referee Organization

Professional Referee Organization (PRO) is the organization responsible for managing the referee and assistant referee program in professional soccer leagues in the United States and Canada, working alongside the United States Soccer Federation, Major League Soccer, the Canadian Soccer Association, the United Soccer League, the National Women's Soccer League, and the U.S. Open Cup.

The organization's targets are to increase the quality of officiating in U.S. and Canadian professional leagues, develop more professional-quality officials at a younger age, and produce officials who will represent the United States and Canada in FIFA competitions. The referees employed by PRO are represented by the PSRA.

History

PRO is another step toward the improvement and professionalization of our top referees. With the additional resources and funding provided by the formation of PRO, we will continue to build upon the progress we've already made."
