Basketball Officials Register for Arbiter
In order to be assigned games, all officials must register for The Arbiter. There are now two arbiter sites for Chicagoland Basketball Officials to get game assignments. If you are registering for HIGH SCHOOL ONLY, you will need to register through the Chicagoland High School Basketball Assigners website. Information on the arbiter site for NON-HIGH SCHOOL GAMES can be found here.
