Diamond Bar AYSO - Region 31

2022 Fall Core

Our Fall Core 2022 registration is open! We are running an early bird special for all families who register before June 1st: $99 Registration Fee + $20 AYSO National Fee. Take advantage of this low price before it goes up. The early bird price will not be accepted after May 31st. Starting June 1st, the price will increase to $139 Registration Fee + $20 AYSO National Fee. We have divisions to accommodate birth year 2004-2019. We also have a Fall 2022 VIP league for our friends with special needs. If you have any special needs children (or adults) who are interested in joining the fun, you can register on our website for a special low price! 

For Schoolyard, U6 and U8 divisions, all uniforms are included in your registration fee. For U10, U12, U14, U16 and U19 divisions, you will be purchasing your uniform from the designated website to ensure sizing is accurate for your player.

Registration will run through the middle of July. The Fall 2022 season will begin in August and run through November, ending prior to Thanksgiving. Remember we are a volunteer based non-profit organization, therefore we rely on parents, friends and older siblings to volunteer as coaches and referees. Please take this into consideration when registering your child(ren). The kids always love to see their parents involved and it's such a rewarding experience. All training is provided to coaches and referees, and coaches receive standard coaching equipment, and referees receive uniforms. This is all provided at no cost to you, so get signed up on our website!

Please read the below information carefully:

  • Teams and coaches are assigned once registration is closed and no team changes will/can be made once teams are formed.
  • Practice days and times are organized and decided on by the coach. You must work around the coach's schedule as he/she is volunteering their time so these kids can play this awesome sport.
  • All games will be played on Saturdays, with the exception of our U14, U16 and U19 divisions. 
  • For Schoolyard, U6, U8, U10 and U12 divisions, all games will be played at local Diamond Bar schools & parks.
  • Practice and game locations will not be assigned until after teams are formed.
  • If we do not have enough volunteers, we cannot form teams.
Divisions are based on birth year, 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.

If there are any questions or concerns, please feel free to reply to this email at any time.

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!

**Cancellation Policy**
If you register and later decide to cancel and request a refund, refunds will only be given for the base registration fee less the cost of the uniform. For U8 and younger, the uniform cost will be deducted from your refund. For U10 and above, you will not be able to receive a refund for your uniform once it is ordered. The $20 AYSO National Fee cannot be refunded. Please email [email protected] with your cancellation/refund requests.
