Walk into a tryout and you hear A team, B team, pre-academy, academy, Blue and White, Premier and Classic. None of that vocabulary is standardised. US Youth Soccer says so in its own rulebook: the different terms used to describe each league "do not necessarily reflect the level of ability or talent of teams participating in the league."
That is the thing to hold on to. A club's internal labels are the club's marketing. What is written down, and checkable, is the league each team plays in and the roster rules that league sets.
What is actually defined, and by whom
US Youth Soccer publishes definitions it suggests state associations use, and they sort leagues by entry rule rather than by standard of play.
- A recreational league is one where tryouts, invitations and recruiting are prohibited, the club accepts any eligible child, players are distributed to make teams even, and "each player must play at least one-half of each game except for reasons of injury, illness, or discipline."
- A classic league permits tryouts and selection on ability, and adds rules restricting how players may be rostered.
- A premier league permits selection and adds no rostering restrictions beyond anti-recruiting rules.
So the line the definitions draw is between no-cut soccer and selected soccer, which is the same line rec against travel covers in full. Inside selected soccer, no national body defines an A team, a B team, a pre-academy or a pool player. Those are each club's own words for its own arrangement.
The word academy is the one worth being careful with, because anybody can print it. It has a real sense only inside a specific league: MLS NEXT's top tier is built from MLS club academies plus independent clubs it calls Elite Academies. Rec, travel, club, academy untangles the four words.
Roster sizes are published, and they are the concrete thing
If you want to know how many players will be competing for minutes, the roster caps are written down, league by league.
| Competition | Roster limit | Game day |
|---|---|---|
| US Youth Soccer, general policy | 22 players maximum, 7 minimum | 18 maximum, 7 minimum |
| MLS NEXT Homegrown Division | 28 per age group, minimum 14 Primary Players | 18, including 7 substitutes |
| ECNL | 30 maximum, 15 minimum at the start | not set in the competition rules |
| Girls Academy | 30 registered, minimum 10 Primary players | 18 |
The Girls Academy figures come from its 2022-23 Technical Standards, which is the most recent edition it publishes publicly, so treat them as three seasons old.
Read the first two rows together and the maths is worth doing before a tryout. A Homegrown Division age group can carry 28 players and dress 18. Ten of them are not at the game.
The one place a two-team structure is written into a rulebook
MLS NEXT's Homegrown Division defines two categories of player on the same club roster, which is the closest published thing to the A and B distinction clubs describe informally.
A Primary Player is one of the "Top players at each Club who are expected to be registered only with MLS NEXT Homegrown Division and cannot play in any outside competition or league without prior approval." A Future Player is "a Player who is Rostered with a Club who is not ready to contribute at the MLS NEXT Homegrown Division level full time."
The difference is not only playing time. Primary Players must forgo playing high school soccer at the same time unless the league grants a waiver; Future Players "are permitted to participate simultaneously in both". Which category a club puts your child in changes what else their year can contain. High school soccer against club works through that specific trade.
Why big clubs field a lot of teams
Sometimes the club has no choice. ECNL's competition rules state that "Every ECNL Member Club must field an ECNL Team in all six age groups," U13 through U18/U19. A club joining ECNL is committing to six teams before it thinks about anyone else, and it runs Pre-ECNL for U12 and younger separately.
A club can also hold places in two competitions at once. In ECNL's own 2026-27 movement announcement, Napa United, Oakwood SC and Rochester NY FC each appear on both the ECNL Boys and the ECNL Regional League Boys joining lists. What no ECNL document says is whether a club can hold both at the same age group, so if that is the arrangement you are being offered, ask the club to put it in writing.
Playing time: what is guaranteed and what is not
Guarantees exist at the bottom of the ladder and nowhere above it.
- US Youth Soccer's definition of a recreational league requires at least half of every game.
- AYSO builds it into its Core program as Everyone Plays, and keeps the same 50% rule in AYSO EXTRA, its tryout-based competitive step for ages 10 to 19.
- US Soccer recommends, as a best practice it explicitly does not mandate, that every player gets at least 50% of each game in the small-sided formats through U12.
Above that, no governing body and no national league we checked publishes a playing-time minimum. ECNL, the Girls Academy and MLS NEXT set roster caps and match-day squad sizes; none of them says how the minutes get divided. That decision belongs to your coach, with nothing written above them.
Which makes the question you ask the coach a specific one rather than a hopeful one. "Where do you see her in the roster?" gets a usable answer. A coach who says "she would be in the rotation but probably not starting" has told you what you needed. What that means for your child is judgment, and it depends on things no study covers: nobody has measured what happens to the specific player who takes a bench spot on a stronger team instead of starting on a weaker one.
One thing measured nearby is worth holding next to that decision. Asked why they stopped playing, the biggest single answer former youth athletes gave in the Aspen Institute's 2025 survey of 3,827 children was feeling not good enough (29%), ahead of bad coaching (21%). The top reasons they play at all were having fun (48%) and playing with friends (47%).
What to ask before you accept a place
- "Which league and which flight does this specific team play in this season?" The league is checkable; the letter on the team name is not.
- "How many players will be on the roster, and how many dress for a game?"
- "Who coaches this team, and are they on staff for the year?"
- "If my child develops faster or slower than expected, what moves between teams look like inside this club, and when do they happen?"
To see which leagues the clubs near you actually field teams in, browse the club finder and filter by level. The youth soccer ladder explains what separates one level from the next.
