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 (More matches/more learning). 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 please note:

1. We will only be allowing competitors and coaches on the main gym floor. All others will be asked to remain in the bleachers. This will make for a much smoother and safer run event.

2. 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.

Important message to the academies

The academy of the registrants must be EXACTLY the same to add the academy points and to avoid a match between teammates 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. Also IMPORTANT: ONLY the 'Academy' field in the registration form will be taken into account for the Award for 'Most Dominant Academy'.
