McLean Soccer employs certified referees for all age groups based on availability. If no referee is present 10 minutes before the game the coach should call the assignor and ask if a referee will be provided. If no referees are available the coaches are asked to referee as objectively as possible and report the shortage to the assignor, Amr Alian (amrelian@yahoo.com) , when the game is complete.
Where certified assistant referees are not available, McLean Soccer uses club, or volunteer assistant referees who have responsibility for noting only in and out of touch and direction.
For some of our Travel Leagues, due to the shortage of certified referees, parent volunteers must also become certified referees called Step In Assistant Referees (STAR). In many cases, as many as two parents per team are required.
