Develop your skills by learning about mechanics, racing, the competition, rules and what a NASCAR race official does. Participate in grassroots level race circuits. These circuits are a great resource for learning the various responsibilities a NASCAR Race Official must assume, such as inspecting, scoring and flagging.
Visit NASCAR's official website and click on their "Jobs" link. This will bring you to a page where you can find listings for open NASCAR race official positions as well as find information on how to apply for these jobs.
Contact the NASCAR headquarters and talk to the personnel department to see if there are any open positions. If there aren't ask if you can keep your resume and application on file in case a position does open up.
