Referees must pass a physical fitness test prior to annual recertification and upgrading. The referee must pass all of the events that are part of the test at the same testing session. The Endurance Test should be run first. If any part of the physical fitness is not completed, the referee may attempt that particular test again at the same session.. All of the fitness test must be completed successfully in a particular session. If not, all test components must be repeated at another session.
