Get ready for tournament season: Is your player's U.S. Chess membership up to date? 

A U.S. Chess membership is required to play in all rated tournaments. Your child's membership will be honored not only at scholastic tournaments, but also at any rated chess tournament in the United States. 

OSCO will sponsor a one-year membership for new players at no cost to parents. If your player's U.S. Chess membership has expired, you can renew it through us for the discounted price of $10. 

Look up your player here if you're not sure if your player has had a membership before, or if you need to see if it has expired, 


OSCO will only process membership requests for players who are registered in an upcoming tournament.

After your player is registered for an upcoming tournament:
