Be sure to know the rules!
When preparing for a national TSA competition, be sure you have read - and supplied to your members - TSA's general rules, as well as the rules for specific event(s) in which your members plan to compete this year. General rules are available in Total TSA and on the TSA website at this link, and specific event rules are bookmarked in Total TSA.
Also, be sure to check the addendum & competition updates on the TSA website. Competition updates will be posted no later than January 1, of the current grad year.
