Trial Events

To submit a new event, please follow the process for revising or taking an event from a Concept to a Pilot to a Trial to an Event:

  1. If you have a great new idea to propose as a future event, first determine if an event has already been written or tried that could then be more easily revised rather than starting anew by reviewinw the Event History Chart, the current list of Event Descriptions and the Trial Events.
  2. The next next step is to write and format the Proposed Event Rule/Revision using the Rules Template. Remember to: Include author's name and email (and if possible, the date and tournament where the event will be run). Submit the Rule to the director that has agreed to host the Pilot.
  3. Pilot the Proposed Rule at one or more of the authoring host state's invitational, regional or state tournaments.
  4. After successfully piloting the proposed event, submit the Student Evaluations and Supervisors Evaluations and the formatted Rule to SO HQ who will determine in conjunction with the Content Chair/Committees if the event is a Promising Pilot that other states should be encouraged to Pilot (some sign up to run at the annual Leadership Meeting).
  5. After successful Pilots/Trials and Evaluations from two or more other states, Content Chair/Committees will recommend to the Board the best placement as a Featured Trial Event on one of the six Event Chart timelines.
  6. Committee Chairs submit Chart recommendation to the Board for consideration and approval.

To ask questions about a specific Trial Event or to find out which events will be held at your tournament, contact your Regional or State Director. To Submit a National (only) Trial Event Question, click on the FAQs page and please submit them under Trial Events.

Note: For the National Tournament the Trial or Open Events do NOT count for team points and ANY team (regular or alternate) member can participate ONCE in each Trial or Open Event.
