Your athlete’s age group is based on their age on August 1st.
| Team | Ages |
|---|---|
| 10 & Under | 10, 9, 8, or 7 on next August 1st |
| 12 & Under | 11 or 12 on next August 1st |
| 14 & Under | 13 or 14 on next August 1st |
| 16 & Under | 15 or 16 on next August 1st |
| 18 & Under | 17 or 18 on next August 1st |
Example, if a player is 14 years old on August 1, they are eligible to compete in the 14 & under team. If an athlete turns 15 on July 30, his/her age is 15 on August 1st and is therefore no longer eligible for the 14 & under team. They are, however, able to participate in the 16 and under team.
