Typically athletes play within their own age group. For example, if a boy or girl is born in 2012, they would play in the 15U age group in the 2027 season. This ensures that the athletes play with kids in their own age and school grade. However, (with the exception of 12U and 13U athletes who must play in their age group year) 15U and up athletes born after September 1, 2012 can play down an age group. For example, a boy or girl born in 2012, September 1st to December 31st has the option to play in the 14U age group. While this option is available, most play within their own age group.
