Is it necessary to join the National Chess Organization?  No.  While there are many benefits to being a member of the USCF, your local club can compete and instruct without any ties or obligations to the USCF.

Why should chess players support the United States Chess Federation?  This non-profit organization supports chess at all levels of play.  It maintains active ratings for all members and allows players to compete within certain defined ability groups, taking into account recent improvements in play at all levels.  The USCF helps organizers maintain a high code of ethics and reporting of results.  Local, state, and national championships are recognized, and international players are sent to compete in FIDE (the International Chess Federation) as they reach certain playing levels.

How much does it cost?  Since the USCF is a non-profit organization, membership allows players to receive a national magazine and have access to discounts on members' items from the USCF store.  Yearly dues are currently $15, 17, and 25 for those reaching age specifications:

1. Age 12 and under receive the Chess for Kids magazine 6 times a year at a cost of $17, $15 at TRM tournament.
