Request an Invoice for the Competition Series

The person who completed a school's registration (typically a coach, bookkeeper or other school official) can get a school's invoice by clicking on Orders under the Account menu at the top right of our website (marked in green).

If, after looking in that Orders section, you are unable to locate your invoice, please send an email to [email protected] with the subject line "Request Competition Series Invoice," and in your email include your school name, city, state and ZIP code.


Get Information about a Chapter or State Competition

Find dates, locations and contact information for your competition coordinator with the Chapter and State Competition Search tool. More than 600 volunteer chapter and state coordinators run local competitions and can answer other questions about your local program.
