U.S. Soccer is committed to producing a variety of referee education resources aimed at supporting the approximate 140,000 members across the country that service amateur games at the youth and adult levels.
High quality instruction provided by the 55 State Referee Associations is paramount to the success of the U.S. Soccer Federation Referee Program.
In addition to supporting development within the State Referee Associations, U.S. Soccer also focuses on identifying officials with the potential to succeed at the professional and international levels. To further these efforts, U.S. Soccer assigns a network of highly qualified staff to various elite-level regional and national events to identify the program's up-and-coming and top performing officials.
The Professional Referee Organization (PRO) is responsible for managing referee programs for the professional soccer leagues in the United States and Canada. Its mission is to provide world class match officials for all professional soccer in North America. PRO assigns games played in MLS, NWSL, USL, and NPSL.
