If you’re interested in becoming a USAC official, George Knight holds an annual class in February where you can earn your Entry-Level official’s license. If you missed or can’t make the test in person, you can take the class and test online at any time. Find the “Officials – Category C Online Course” on this site (make sure you’re logged into your USAC account) and check the box next to it that says “FREE” to begin the process. There is more information about becoming an official available here.
If you’ve lost your Officials Manual or just want to brush up, resources are available here.
