They are different for every region
For Region IV-1A:
Two teams are tied: The team with the best record in head-to-head play will be the Champion and have the higher seed. If the two teams split during the regular season, one game playoff will be played at a neutral site to determine the Champion and Runner-up. The Executive Committee will determine the neutral site
More then two teams are tied: The team with the best record in head-to-head play among the tied teams will be the Champion and/or Runner-up and have the higher seed. If the teams are still tied the following format will be used:
Three team tie- If all teams have identical head-to-head region records, goals for, goals against, a hat draw will give one team a bye and the other two teams will play, with the winner playing the team that had drawn the bye for the Champion/Runner-up or the third/fourth seed
