Age brackets for Youth Lacrosse are established by US Lacrosse and are based on a player's age as of August 31 of the summer prior to play. These guidelines have been adopted by High Sierra Lacrosse League (HSLL) for use in the Truckee/Tahoe/Reno region.
Whereas more densely populated regions, where lacrosse is well-established, often breakdown their age brackets to the single year level, HSLL combines two age brackets to form one. For example, the 7U and 8U brackets are rolled together into a single 8U bracket, meaning all players were 8 years of age or "under" as of August 31 of the prior summer.
Some variances are allowed under certain circumstances, including but not limited to the following:
For the 14U bracket, HSLL typically allows any 8th grader who has not yet played lacrosse at the High School level.
If a player had a birthday slightly before the August 31 cut-off and is therefore put into an age bracket ahead of his/her peers, an exception is sometimes made to allow that player to "play down" one age bracket. A petition must be filed with HSLL before that can take place.
