IBJJF rules explained: points, advantage, penalty, and what's legal and what isn't

Anyone who starts watching BJJ tournaments runs into chaos pretty quickly: points, advantages, penalties, disqualifications — and on top of that, techniques that are legal in one place and illegal in another. This article is a simple introduction to IBJJF rules for people who want to understand the basics. It's not a complete referee manual. It's practical orientation, so you know roughly what decides a match, and why something that flies in training may not be allowed in competition.

What IBJJF is

IBJJF is the International Brazilian Jiu-Jitsu Federation — one of the most influential organizations in competitive BJJ. It runs the major tournaments, and its rules serve as the main reference framework for many people, even though other rulesets obviously exist. The IBJJF website currently has Rule Book v6.1 from 2024 available, along with supporting materials on technical fouls and illegal techniques. ibjjf.com

Knowing the rules makes sense even if you don't compete. They help you understand why someone is pressing for a guard pass instead of a risky submission, why someone is content with positional control, and why referees sometimes don't reward a "nice attempt," only a stable result. That's useful both for watching matches and for your own training.

How points work

The basic logic of IBJJF is simple: points reward reaching and stabilizing a more advantageous position. The rulebook explicitly lists, among others, these main scoring actions: ibjjf.com

Stabilization matters too. For many scoring situations, IBJJF requires you to hold the position for roughly 3 seconds — otherwise, instead of points, you may only get an advantage, or nothing. That's exactly why it isn't enough to just "touch" the position for a moment. ibjjf.com

For a beginner, the practical takeaway is this: it isn't enough to make the action. You also have to finish it and settle it.

What advantage is

An advantage is, in practice, something like "almost a point." IBJJF awards it when an action came close to scoring or close to a finish, but wasn't carried through to a full result. The rulebook gives examples: an almost-stabilized takedown, a near-completed sweep, near-mount or near-back control, or a dangerous submission attempt that forced the opponent into a real defense. ibjjf.com

Advantages are counted separately from points. They aren't "half a point." They only matter when, at the end of the match, the main points are tied. The practical rule: points first, advantages are an additional layer of decision-making.

What penalty is

A penalty is a punishment for breaking the rules. In a regular match, this most often deals with stalling, escaping the area, certain technical fouls, or unsportsmanlike conduct. IBJJF has a clear system for the standard penalty sequence: ibjjf.com

1. 1st penalty A penalty is recorded against the opponent on the score
2. 2nd penalty The opponent receives an advantage
3. 3rd penalty The opponent receives 2 points
4. 4th penalty Disqualification

For stalling situations, the rulebook also describes that the referee handles lack of combativeness separately and that not every "delay" is automatically stalling. For instance, when someone is defending from a genuinely bad position, the rules don't treat it the same as deliberately killing time without an attempt to progress. ibjjf.com

For a layperson, the main thing to remember is this: penalties aren't just formal warnings. They can really change the outcome of a match.

What legal and illegal techniques mean

This is where the most confusion tends to come up. In training, someone may show you a technique that's technically correct and routine, but which you can't use at a particular tournament. In IBJJF, legality doesn't depend only on what you're doing, but also on age, belt, format (gi or no-gi), and the specific division. ibjjf.com

That's exactly why it's better to understand the principle than to memorize one universal sentence for all situations.

Heel hook and knee reaping

The IBJJF update introduced heel hooks and knee reaping for adult brown and black belt no-gi divisions starting in 2021. Outside of that scope, they're significantly limited or banned, depending on the specific division. ibjjf.com

Toe hold, knee bar, wrist lock, and other techniques

Slam

Slams are banned in IBJJF across all categories. ibjjf.com

In practical terms: when you're not sure, don't go by what you heard at the gym or in an internet comment. The final authority is the current IBJJF rulebook and the official IBJJF materials.

The difference between training and competition legality

In training, gyms often work with techniques that aren't allowed in some divisions. That's not a problem in itself, as long as the gym knows what it's doing and adapts to the level of the people on the mat. The problem starts when a beginner equates "we train it" with "I can use it in a tournament." Those are two different things.

That's why it's normal for a gym to teach a broader repertoire while the coach also says: this one is currently outside the rules or outside a safe level for you in competition.

How to use it in practice

You'll use this article in three situations: when you're watching matches and don't understand why someone is leading on points; when you're getting ready for your first tournament and need basic orientation; or when you want to clarify why something is being trained at the gym, but may not be allowed in competition.

On a practical level, take this away above all: first understand scoring and the basics of penalties, then deal with the details of the legality of individual techniques.

Conclusion

IBJJF rules aren't as complicated as they look at first glance. The basics are fairly straightforward: points reward control and progress, advantages handle "almost-completed" situations, and penalties punish errors or stalling. The more complicated part is the legality of techniques, because that depends on the specific division. So it's good to understand the principle, but don't pretend that one general list will cover you. The final authority is always the current IBJJF rulebook. ibjjf.com
