The International Brazilian Jiu-Jitsu Federation (IBJJF), founded in 2002 and headquartered in Rio de Janeiro, Brazil, is widely regarded as the largest and most prominent sanctioning body in competitive Brazilian Jiu-Jitsu. It organizes the sport's most prestigious tournaments, including the World Jiu-Jitsu Championship, Pan Jiu-Jitsu Championship, European Open, and World No-Gi Championship, drawing thousands of competitors to its largest events each year.
IBJJF rules are the standard most BJJ competition rules descend from. Matches are scored on positional progress: 2 points for a takedown, sweep, or knee-on-belly; 3 points for passing the guard; and 4 points for mount, back mount, or back control with hooks. Advantages are awarded for near-scores and close submission attempts and act as the first tiebreaker, followed by penalties and finally referee decision. Match length scales with rank, from 5 minutes for adult white belts up to 10 minutes for black belts.
Legal techniques expand with age and belt. White belts face the tightest restrictions (no wrist locks, slicers, or kneebars); jump to purple and brown/black and more leg attacks and pressure submissions open up. Since the 2021 rule change, heel hooks and inside knee reaping are legal — but only in the adult brown/black no-gi divisions. Kids divisions run shorter matches with a much more restrictive legal-technique list.
Uniform rules are enforced: gis must be white, royal blue, or black, properly fitted, with a rank-appropriate belt; no-gi divisions require rash guards displaying the competitor's belt color. Referees can disqualify for illegal gear, so check the uniform checklist before stepping on the scale.
Always confirm the official rulebook before you compete — organizations update rules between seasons. See the official event page for current rules.
