(DECATUR) A recent report shows the number of referees in Illinois continues to sink, dropping by 11% over the four year period ending last year in 2017. The Decatur Herald & Review reports the Illinois High School Association says the number of referees fell last year from nearly 12,200 to fewer than 12,000. While referees are required to pay $50 to be licensed in a specific sport and $15 to additional sports, an official must pass an open book exam to obtain the license, which must be renewed annually. The report shows the number of licenses issued in Illinois also dropped by 9% during the four year period that ended last year. The IHSA says the drop in referees is partially due to referees’ poor treatment during games.
