Diamond Bar AYSO - Region 31

Fall 2026 Season

Our Fall Core 2026 Registration is OPEN! 

We are a volunteer based non-profit organization, therefore we rely on parents, friends and family to volunteer as coaches and referees. All training is provided to our volunteers, and coaches receive standard coaching equipment, and referees receive uniforms. This is all provided at no cost to you. This is a great opportunity to learn the game and be involved in your child's experience. Most training is online, with the exception of a short field course taught by our region's coach instructors. Volunteering and being a part of your child's experience in soccer is something they'll never forget! 

UNIFORMS
Schoolyard, U6 & U8: Full uniform & a small picture package is included in your registration cost
U10-U19: Uniform will be purchased online by the parent, at an additional cost, once teams are formed and a coach is assigned. The uniform link will be emailed to you before the beginning of the season.

REGISTRATION DATES & COST
Now - May 31, 2026
ALL DIVISIONS: $149 Registration Fee + $25 AYSO National Membership Fee

June 1 - July 4, 2026
  ALL DIVISIONS: $199 Registration Fee + $25 AYSO National Membership Fee 

July 15 - July 30, 2026 - LATE REGISTRATION

ALL DIVISIONS:
 $299 Registration Fee + $25 AYSO National Membership Fee. Teams are formed and kids are placed where there is an opening. 


Teams and coaches are assigned once registration is closed on July 4th, and no team changes will be made once teams are formed as all teams are balanced based on ratings. If we do not have enough volunteers, we cannot form teams. Divisions are based on school year age, and this is decided at a National level, not by us as a region. We will not be able to move a player down to a younger division. If you are concerned about your player being in the assigned division, please know they will be playing with kids their same age.

Per our Region and National guidelines, there will be no team or coach requests accepted. Circumstances such as playing with family members may be considered, but must be requested by July 1st. AYSO's philosophy of Balanced Teams means every team must have the same skill within that division. If family requests need to be made, please email [email protected] and the decision will be up to the Board of Directors.



Thank you for all of the support you have given Region 31. We look forward to seeing new and returning faces this upcoming Fall season!
