This change will not impact the Spring 2026 season and our current travel teams will remain as they were in Fall 2025. This change will begin for the Fall 2026 season such that this year's Competitive Academy tryouts will run by August 1 + grade year.

Example 1 - August 15, 2015 birthday and going into 6th grade - plays with 6th grade team (U12).

Example 2 - August 15, 2015 birthday and going into 5th grade (held back in terms of grade year) - plays with 5th grade team (U11).

This is a significant shift that will impact every Competitive Academy team. The Board has worked tirelessly to determine best handling and will continue to work with our staff, volunteer coaches, and families to make this transition as smooth as possible

This is the right way to handle $500 a year, volunteer coached teams. Let them play with friends.

And another oh oh....

With the change, I highly doubt there will be more than 5-10% of grade below playing on any older team. Slightly different in Sept+ and August states but not by much since there weren’t that many kids in those months to begin with.

So grade is going to be a fair proxy if 95% of kids are corresponding to the same grade in school vs 75% as is.

Yes there will be edge cases with hold backs or exceptional players or random school start dates but lets stop governing by minor exception vs the rule.

You arent seeing a bunch of May, June and July holdbacks in ECNL grad year info. Expect at least 10 percent of players off of the more traditional grade year from so many birth months that the only a rule to go grade year would be able to make club soccer grade year. And their just isn't the documentation for grades to make grad year enforceable in any way.

Aug birthdays playing with their grade doesnt have to be enforceable. It works because players get better visability with college coaches and clubs because of player better visibility to college coaches gets more college committments.

Add in that 8th grade teams dont have 9th grade players leaving the team for 3 month during the season to ay HS soccer.

Theres reasons all round to play Aug birthdays with their grade in school.

It also helps boys because if you're playing a grade down level in SY it would be nearly impossible to get recruited to play on a MLSN HG BY team. This is because the BY players would be older and there would be biobanders which are even older.

Ridiculous, MLSN1 are recruited by contacting MLSN1 teams unless the boy is top of the top. Tryouts are based on going to practices for new club not some highlights or showcase ID. The nutty ways you try to get youth soccer to go grade to help your kid is crazy, crazy, crazy.

Has nothing to do with showcases. I wish you understood math and calenders.

If you're an Aug birthday in SY playing down. You're used to playing against players that are roughly 1 year and 6 months youger than the oldest in an equivalent BY group.

if you're an Aug birthday playjng with your grade in SY. You're used to playing against players that are roughly 6 months older than the oldest in an equivalent BY group.

Add in biobanding in MLSN and you can see why Aug boys playing down in SY leagues wont be considered for BY MLSN HG.

Aug guy so hypercritical. Denying RAE while calculating these age month difference

The more nonsense you post the more opportunities it gives me to explain why Aug birthdays should play on teams that are their grade in school. The more educated parents get about SY the more they'll demand that clubs play players on the correct grade in school team.

The problem it is very clear that you are trying to get youth soccer to go grade based to help your specific situation. You aren't trying to help anyone but yourself. If US Soccer wanted to go grade year, they would have. They didn't. Clubs are trying to push as many players as possible to the new correct age groups they don't care about grades. It is a heavy lift when many want to be special. Tell your coach your kids grade and watch their eyes glaze over with not caring.

Keep lieing.

Multiple parents have reported on this thread that clubs are asking players in tryouts when they were born and what grade if they are an Aug birthday.

Are these parents in the therapy session with you?

The scariest part is your clear detachment from what's real

In your mind, the League has Calendar based Age criteria for players.
But in your Stephen Spielberg movie, your club can make up their own rules for you and other parents with kids who can't handle playing their assigned age group

Uh oh....

The only issue are idiots like the Age guy thats trying to convince Aug birthdays to play on a team thats a grade down.

Nobody but you is trying to convince anyone to do anything.

People are telling what leagues, clubs and college coaches said. Leagues set rules, 8/1 then clubs said only best of best get considered to play up then college coaches said in Facebook chat and 2 club announcements that you found that playing up or the age of the recruits doesn't matter to them.

All this really seems to really hurt your feelings so you lash out like a toddler saying you are correct and everyone else is wrong but never offer any facts or citations, it's always just your flawed opinion.

1. The idea here is for kids to play with their school grade. Every US Club/US Soccer communication says this. 7/31 is the earliest cutoff meaning as long as your kid started school on time, they are allowed to play with their school grade. This was the goal.

2. The term they use for kids playing a grade below because of school cutoff and birthday after Aug 1 is "force down" not play down, because playing down isn't allowed, but playing up is. So a "force down" is when a club forces a player to play with a lower grade. This was not the intent of the change.

3. One of the specified goals was to help facilitate college recruiting because college scouts are usually recruiting a specific graduation year. They are not often looking at multiple age groups at once and they will be going where the majority of the players they need are playing. If you aren't playing with your graduation year, you are at a significant disadvantage and this was acknowledged so the change is truly meant to align this.

More to the point, they said they wanted to better align with grades, reduce trapped problem and increase participation. By not saying they wanted to perfectly align with grades or eliminate the trap problem, they did what they said they would do. They created age groups based on 8/1 - 7/31 and are not consider grades as criteria for age groups for the rules.

How can you say...

"they said they wanted to better align with grades"

and

"and are not consider grades as criteria for age groups"

The hypocrisy is mind boggling.

No hypocrisy. Find where US Soccer has a rule for youth grouping to be grade based, otherwise you have no defendable position.
