Proving Grounds is Washington State's longest running Submission Only BJJ/Nogi Grappling Tournament. We run all brackets in a round robin format to give every competitor the most possible matches. Great for Adults and children. High level competition and a guaranteed good time.

In an effort to stay true to our mission of offering the best possible tournament format, we will be making a few significant changes for future events. The following changes should make for a more exciting, competitive, and inclusive event.

1. Most "Dominant Academy" award - This title will be given to the academy (defined by a single address/location. Not to be mistaken with affiliation/multi locations) with the greatest number of submission finishes.

2. Due to many requests, we are now adding a "Master 4" division for competitors 50+ years of age. It is our hopes that this will bring many more of our "not as young as we used to be" competitors out for a day of fun on the mats.

3. As Washington State's longest running Submission Only Grappling Tournament, Proving Grounds will soon be stepping up it's tournament presentation. Look for many cool new features over the coming events. Stay tuned here and on our Facebook page (KYS Promotions) for more info.



Take advantage of a super deal and get more matches BY REGISTERING FOR BOTH GI AND NO-GI. (2 DIVISIONS FOR 60.00 DURING EARLY REGISTRATION). Price discounted at checkout.

Important message about the academies: the academies of the registrants must be EXACTLY the same to add the academy points and to avoid a match between team mates in the 1st round of a bracket. For example: 'RSU' and 'Ring Sports United' will NOT be considered as the same academy. You can change your academy by logging into your account. IMPORTANT: ONLY the 'Academy' field in the registration form will be taken into account for the prize for 'Most Dominant Academy'. Please leave the 'team' field blank to avoid any misunderstandings.
