My son started training in Brazilian Jiu Jitsu at the age of 5. Assuming he continues this, what belt should he receive once he is in the adult class? According to the belt chart, it would be blue or purple depending on the instructor? We are talking 11 years of experience at that time.

I would like to point out that we are in no hurry for him to get ranked or given any handouts. I am only curious to see what 11 years of experience would make on receiving the adult belt. I ask this because if 11 years of experience gives him a blue belt, then why does 2 years give an adult white belt a blue belt? 11 years of experience would give an adult at least a brown and maybe even a black belt (if deserved obviously). I know I am getting ahead of myself but I am just trying to make sense of this.


Most Brazilian Jiujitsu schools do have children's ranks which automatically get turned into adult ranks when they turn 16. So a children's orange belt will become an adult's blue belt automatically at age 16. A children's green belt will automatically become an adult's purple belt at age 16. This is usually how it's done, but a teacher might decide to award higher or, very rarely, lower adult rank depending on the student's ability, experience, and attitude.

With over 11 years of experience, your son should probably get ranked at least purple belt, maybe higher. I would think so, anyway.

The thing you might want to keep in mind about Brazilian Jiujitsu is that there's fairly good agreement between different schools about what a blue belt should be able to do, what a purple belt should be able to do, and so on. And yet, it's completely normal to find blue belts that are able to win against purple belts, and purple belts that can often win against brown belts and some black belts even. That's normal.

Each school's instructor has a set of criteria they use to judge whether someone should be advanced in rank. A blue belt may be able to tap some brown belts, for example, but maybe that's only because they've become really good at a particular technique they rely on a lot while not developing the other techniques they need to develop in order to get promoted to the next rank. The teacher in that case, might be holding the blue belt back until he can get better at the techniques he's supposed to know before being promoted.

It's not all about winning, in other words.

So if you ever wonder if/why your son is being "held back" in rank, go ask the teacher what your son has to learn in order to be at the rank you think he deserves. Ask respectfully. Don't accuse. Most teachers will not hesitate to tell you what your son still has to do. Your son should know it as well, so he knows what to work on.

  • According to IBJJF graduation standards(ibjjf.com/info/graduation-system), someone under the age of 16 can only be promoted directly at graduation if they have been a green belt for at least two years.

The training with children is (or at least should (in my opinion)) more playfull, you can take your time with techniques, make sure it's a bunch of fun. Sitting still, discipline etc are still to be learnt, this also is part of what is to be teached.

The training with adults is (at least should be) more focused, a certain degree of self discipline can (should) be assumed.

Different prerequisites ...


The years of experience is not the only consideration for the graduation. Also opposite that Steven said I never so a student get a different belt of the blue when this turn 16 years old.

At IBJJF.org has some rules about the time between the belts. But this rules aren't very strict and very hard to make it happens. The athlete should be in the belt at least 1 and half year.

The first belt is the white. Doesn't matter the age. A student who get any color belt (child or not) should not return to a white belt in case of change the age category

I'm sure your son will receive at least a Blue Belt. If your son shows a very high level for a Blue belt possible the teacher will give to him a new belt soon.


This explains how it works pretty well (for the IBJJF)

In short, you can become a blue or purple belt at age 16. You can't get brown until 18, or black before 19.


Depends on the school, he would either get a blue or purple belt, he could also possibly be given an adult white belt

    Could you expand your answer to explain why he would get a particular belt?
