OSCO is an all-volunteer 501(c)3 non-profit organization with all proceeds going directly to benefit the scholastic chess players of Oklahoma. OSCO is entirely funded by donations and residuals from the state championship tournaments. All other tournament proceeds support the school and club scholastic chess programs that organize the events with OSCO's support.

Donation checks are to be payable to OSCO and mailed to the contact address.

OSCO also accepts in-kind donations of products or services directly helpful to OSCO, or to be given away at the state tournaments. In-kind donations will receive the same level of recognition as cash contributions of the same value. Contact OSCO to make an in-kind contribution.

All donors of $25 or more in the last year are voting donor members at the OSCO annual meeting during the State Championship in March. Each donor member has one vote by a representative age 16 or older.

Contact OSCO for more information about donations.

Your support will be very much appreciated.
