Understanding the U15 – U16 Format

At U15–U16, the football begins to resemble senior grassroots in structure. Longer matches, near-full-size pitches, and squad sizes that can exceed 18 players. Many leagues at this age group are competitive and results-focused — but the FA still expects coaches to provide every registered player with meaningful match time across a season.

FA Equal Playing Time Guidance

FA guidance: fair season-long distribution of playing time is expected. Clubs should be able to demonstrate that all squad members receive meaningful match opportunities.

The Rotation Challenge at U15 – U16

With 80-minute matches and potentially 18 players on the squad, managing cumulative season minutes is a real administrative challenge. Many coaches at U15–U16 lose track of who has played across a busy winter fixture schedule — and end up discovering in March that three players have barely featured all season.
