There should be a high standard for earning your rank. if you are not ready you do not get the rank. In our school not many people will ever are a black belt. Some have gone other place because they want rank. We have no problem with that. Some come back and still do not have the rank. Only one of our students that left ever got a black belt through some other organization. We have a high standard in our school. If you do not meet it you will not be promoted. It is that simple. I know of other instructors that will not promote someone to black belt unless they have actually earned it. Some of those students leave in search of a black belt. We have had some of our students that were told by other instructors that they should be higher ranked and that they could train with them and they would give it to them. A few checked out the other schools and decided to stay with us seeing that could have the rank, but they wanted the skill and knowledge to go along with the rank.

I doubt if there are many in your judo school that have been in that school a long time then leave and get a black belt elsewhere then come back. The reason why I say this is because judo generally has a standard curriculum across the board. It doesn't matter where you train you must know the same things. In karate different schools have different requirements, different styles have different kata, forms, strikes kicks, etc. There are many variable as to why it would be different in judo.

Strict requirements for promotion is a great thing!

What would you rather have, a belt just handed to you for little to no effort, or one that is worked hard for through years of training and requires the appropriate amount of knowledge and skill and a grading that actually really tests you on what you can do. Strict grading is a great thing.

Very few people that begin martial arts at a legitimate school actually make it to black belt. They all want to, but many don't want to wait. Unfortunately, many people want it too badly, as in they want to be able to wear a black belt rather than be one. There have been countless people that have left the school I train at, some of which join other schools. Some of those that joined other schools have gotten a black belt in short time, but I don't see them as black belts. Sure, they are wearing one, but they have the same if not worse skill level as when they left. Black belt is not a rank, it is a state of mind. There should be high requirements to reach black belt.

Strict gradings are good gradings. High expectations are good expectations. High requirements are good requirements.

Stop looking at who gets what belt. The real thing of importance is how good each student becomes. In a fight nothing else matters. So if your Judo instructor is strict with ranking good for him. Better fewer people out there with back belts than more that are of lower quality. Black belt is only the beginning of real knowledge, training, and ability. People need to see developing and improving skills as what is important and forget about when they will be this or that rank.

In general, the longer it takes you to advance in belts, the better the school.

In the dojo I ran for years, we had belt tests twice a year, and nobody who tested last time tested the next.

The belt is only a rough guide at best.

You should interested in skills not belts..

I was told recently that for my kodokan judo club getting a brown belt which takes like 3-5 years at my club was the easy part and that all the black belts at my club aren't black belts under my club or sensi but have trained there from the very start or most of there judo life and have only gone to other clubs to get there black belts could this be a bad thing?
