AYSO Hybrid Referee Training for New Referees


For fall 2021, we will be instituting hybrid referee training classes. 
The most important decision to make is what level class you want to take.


U8 Official.

U8 Officials can referee U6 and U8 matches. These matches are official by one referee.

Regional Referee

Regional referees can officiate games in all age groups (from U6 to U19), although we recommend that they start with U10 games and consider further referee classes as you move up the age brackets. U10 and above matches are officiated by a team of 3 match officials - a referee and 2 assistant referees. Both referees and assistant referees take the same training classes. 

The classes will follow the following pattern:
