IBJJF weight limits include the competition uniform. Use the weight chart for your gi or no-gi championship; the first-championship guide says staff call athletes to weigh in when their division starts.

The rulebook uses single elimination, with a special three-athlete bracket: the first match’s loser meets the third athlete for the other place in the final. Check your published bracket rather than assuming a second match.

Yes. Registration requires active IBJJF membership under your current belt and academy. Your academy must be registered and have an instructor who can sign the application; start that process before the event deadline.

Read the individual Open page. For example, Louisville’s December 2026 page lists weigh-ins on the preceding Friday, with a separate early window for kids. That schedule is event-specific; confirm your own event’s time, clothing and documents.

ADCC’s general championship rules describe a knockout tournament in which the winner advances. US Opens can publish their own division details; check the event registration and experience category before assuming a match guarantee.

ADCC’s competition-format guidance requires an original passport from the country or continent served by the qualifier. Its check-in list also includes ID and the tournament-payment receipt. An Open entry does not establish that you meet a Trials passport requirement.

AJP permits a nontransparent T-shirt with knee-length sport shorts, a T-shirt with gi pants, or a full gi. Bring official photo ID. Weigh-in timing varies by championship, so use its published schedule.

No. The competition system depends on the event level, belt and division. Regional, International and National events generally use single elimination; selected Continental and Grand Slam divisions have different systems. Read the rules attached to your exact event.

AJP’s regulations require current-year athlete affiliation and an approved registered academy, including for children. Registration details and membership documents must agree. Resolve a pending affiliation before arriving at weigh-in.

No. JJWL’s FAQ says gi entrants weigh in wearing the gi; no-gi entrants weigh in without it. Use the event’s weigh-in window and change deadline, which can differ from general FAQ examples.

JJWL lists best-of-three for two entrants and round robin for three. Four-to-fifteen-person adult brackets use double elimination; larger adult brackets and youth splits have separate provisions. Check the actual bracket before estimating your match count.

Every competitor must have an individual JJWL account. The FAQ says to reuse that account for later events. Parents are directed to the spectator area rather than the competition area; check the event’s spectator arrangements.

NAGA says to weigh in without the gi, wearing at least shorts. One weigh-in covers your entry. Children and teens have specific weigh-in windows; the event page supplies those times and any previous-evening option.

Its FAQ describes a 2025 change: two-person divisions use best-of-three, three-person divisions use round robin, and larger divisions provide a third-place bracket. Injury, withdrawals and other circumstances can still reduce completed matches.

NAGA’s FAQ permits unaffiliated competitors. Its Smoothcomp registration instructions say to choose NO TEAM when you have no team affiliation. Parents and guardians still need the applicable spectator admission; event pages list the price.

No. The rules require one weigh-in for both formats and allow gi competitors to weigh without the gi. There is no weight allowance. Complete check-in and weigh-in at least 60 minutes before your division’s scheduled start.

No. Regular divisions use a size-dependent system, including best-of-three for two entrants and round-robin groups for larger fields. Absolute divisions use single elimination. Withdrawals can affect the matches actually completed.

Register using the athlete’s legal name and birth date, and their age on event day. The rules make proposed youth mergers optional: a parent or coach can decline and withdraw for credit. The official event page contains registration requirements and deadlines.

No. AGF’s January 2026 general rules say all weigh-ins take place without the gi and specify a one-pound allowance. Confirm the event’s weigh-in session and the correct age, rank and weight division before registering.

No. Regular divisions use best-of-three for two entrants, round robin for three, and double elimination through the path to the finals for larger fields. Challenger divisions have a modified single-elimination format with their own small-bracket rules.

AGF presents USA Grappling membership as a separate athlete, coach and academy program. Its information page requires SafeSport training for adult athlete and Grappling Leader members. It does not establish a universal membership requirement for every AGF tournament; check the event entry conditions.

The July 2026 UWW grappling rules specify a rash guard and shorts, with license and accreditation at medical control and weigh-in. Use the particular US qualifier’s instructions for its schedule and entry process.

No. UWW’s official-event system includes elimination with repechage and different pool formats for smaller fields. The rulebook explicitly allows national and international Open events to use another system, including simple elimination.

The UWW rulebook requires it for the specified international championships and tournaments on the UWW calendar. A US academy membership or domestic event entry is not that license. USA Grappling is the US federation contact for this pathway.

The organizer FAQ says the gi is not required on the scale and provides a one-pound allowance. Check your event schedule for its weigh-in window.

The rules page describes double elimination with exceptions based on bracket size. An older FAQ describes a different format, so ask the event team which bracket applies before relying on a match guarantee.

Use the competitor’s age on tournament day, according to the organizer FAQ. Adults and youth can have separate competition days, as shown on the calendar.

The rules say competitors weigh in once for both formats, without needing to wear the gi. A one-pound allowance applies; check the event for any Friday weigh-in option.

The FAQ says brackets and schedules are generally published on Smoothcomp the day before the tournament. Check your event’s Brackets & Schedule tab for the current version.

The organizer may combine divisions according to turnout. A parent or coach can request female-only youth matches in the registration notes, but the FAQ says this depends on available competitors.

The Bristol event page says to weigh in without the gi, with a one-pound allowance. Competitors entered in both formats weigh in once by the gi deadline; other events may publish different times.

The FAQ lists moves in weight or age before staff contact the family to find a solution. Review possible changes with the coach and event team instead of assuming the original bracket will remain unchanged.

The organizer uses Smoothcomp for registration changes and withdrawal credits. Its FAQ links instructions for finding the competitor’s profile ID, which is also needed for certain discount requests.
