This is the wrong forum for this discussion. 2017s start High School in a few weeks and at that point nearly everyone agrees club teams should be grade based. Please ignore comments of rising 9th grade teams full of 16 and 17 year olds. This is simply not a reality and the statement is made in attempt to spark emotions.

US Lacrosse uses 2 year age groupings because there are simply not enough players in most of the country to field competitive single year teams. With that said, for LI and the rest of the country there are limited age problems on grade based teams with the exception of held back 7th & 5th graders who are U13 and U11 ineligible respectively. A boy would need to be held back twice to be age ineligible as an 8th or 6th grader.

For 2013-2014 academic season (Sept 1, 2013 – August 31, 2014)

U15 = anyone who is age eligible including High School students = boys born on or after Sept 1, 1998
U15 Middle School = 2018 High School grad year (8th grade) = boys born on or after Sept 1, 1998
U13(“AA” or “A”) = 2019 High School grad year (7th grade) = boys born on or after Sept 1, 2000
U13(“B”) = 2020 High School grad year (6th grade) = boys born on or after Sept 1, 2000
U11(“AA” or “A”) = 2021 High School grad year (5th grade) = boys born on or after Sept 1, 2002
U11(“B”) = 2022 High School grad year (4th grade) = boys born on or after Sept 1, 2002
U9 = 2023 High School grad year (3rd grade) = boys born on or after Sept 1, 2004

To illustrate for the soon to be completed 2012-2013 academic season (Sept 1, 2012 – August 31, 2013)

U15 = anyone who is age eligible including High School students = boys born on or after Sept 1, 1997
U15 Middle School = 2017 High School grad year (8th grade) = boys born on or after Sept 1, 1997
U13(“AA” or “A”) = 2018 High School grad year (7th grade) = boys born on or after Sept 1, 1999
U13(“B”) = 2019 High School grad year (6th grade) = boys born on or after Sept 1, 1999
U11(“AA” or “A”) = 2020 High School grad year (5th grade) = boys born on or after Sept 1, 2001
U11(“B”) = 2021 High School grad year (4th grade) = boys born on or after Sept 1, 2001
U9 = 2022 High School grad year (3rd grade) = boys born on or after Sept 1, 2003

A very high percentage of the your team is older than mine and this is why my team lost argument is made to validate to your son why his team lost without having to state the other team was simply better than you during the one hour you played against them.
