Age divisions are determined by birth year.
**No athlete may compete in a younger or older age division in individual events. The AAU Athletics athletes must compete in their own age division with the following exceptions: For relays only, 9 Year Old athletes may compete in the 10 Year Old division. 11Year Old athletes may compete in the 12 Year Old division; and 13 Year Old athletes may compete in the 14 Year Old division.
In track and field, a competitor in the 8-Under, 9 Year Old, 10 Year Old, 11Year Old or 12 Year Old age divisions may enter a maximum of three (3) events. Competitors in the 13 Year Old, 14 Year Old, 15-16 Year Old, or 17-18 Year Old age divisions may enter a maximum of four (4) events. These event limitations include relays, but do not include multi-events. Entry in a relay, either as a principal or an alternate member, will be considered an entry for the purpose of this rule.
