This chart applies to Region 13 players during the MY2025 season, from Aug. 1, 2025 to July 31, 2026. For the 2024-2025 season, see here.

In California, children 6 years old as of Sept. 1 are eligible to enter 1st grade, which corresponds to the 7U division. Region 13 uses that to set the age ranges for 8U and under. The older divisions are divided by birth year. Next year, 2026, all the age divisions will be aligned to the school grades. If your child started school a year later, they will play with the other kids their same age, rather than the same school grade. 

If your child was born on Sept. 1, please write to the registrar to be transferred to the next older division.

For questions about team assignments, please contact your division administrator.

**For 2025 only, players born Sept. – Dec. 2017 can choose to play either in 8U, or the first year of 10U. 

• If you choose 8U, they will be with mostly other 2nd graders, and may play in Grad Series in the winter
• If you choose 10U, they play in the competitive league, with scores and standings. They will play in a championship tournament, and can try out for an All-Star team in the winter. 
• Historically, most kids in this range choose to play in 10U, with goalkeepers, offside, line referees, and the whole shebang. Some of the Region 13’s strongest alumni were the smallest on their team when they first played in 10U.

You have until July 15 to decide (email registrar@ayso13.org). Either way, everyone advances to 10U for fall of 2026. If you are unsure, please ask the coach staff for advice. Emotional development, interest, and physical ability vary greatly among children, and it’s not uncommon for our youngest (or smallest) players to also be some of the strongest players.

Note also that doing the birth date math hurts the registrar’s head. If he did it wrong, please be understanding, and we’ll fix it.
