Birth Certificate required at check-in, for 11-18 Brackets. You will need to have proof of age during the event in the case of an age discrepancy. Plan on bringing a document with each competitor’s name and birthdate on it (driver's license, birth certificate photocopy, passport, etc.) - if your document doesn't have a picture (birth certificate), it is helpful to have a picture ID as well to compare it to (school ID, etc.). In this event, there should not be an age issue, but you never know.
