All adult referees (18+) working TCSL matches must have completed a background check with a satisfactory result.
Information on this process is here.
For adult referees (18+) that are also TCSL coaches and have a US Club Soccer pass:
If you have adult referees that are coaches from a TCSL team, their US Club Soccer coach’s pass fulfills the background check requirement because they have already completed US Club Soccer’s background check requirement. These individuals do not need to complete the MYSA background check. Please send the coach’s pass to firstname.lastname@example.org in order for the referee to show up on the list as a referee who has successfully completed the background check.
