USSF Referee Certification Clinic

COSA is sponsoring a referee's clinic for anyone age twelve and older (you must be 12 at the time of the clinic) who would like to become a United States Soccer Federation (USSF) licensed referee. Passing this class will enable you to be assigned with any USSF affiliated organization, including, but not limited to, COSA and MOSSL games.
