Yes all games in all conferences are officiated by certified referees that are registered to the YSF managed referee association. For info on YSF Referees
These referees are provided, paid for and scheduled by the tournament. Teams in all locations play under the same rules as each other to ensure a non biased state championship driven competition. Coaches and organizations who participate in the tournament play in a “worry free” environment. Teams do not have to worry about the organization of referees, fields, trophies, jerseys, management of games etc. The league handles all this for the teams.
