Many martial arts have systems of judgment of level of the persons who perform them, as the colour of the belts in the karate. In the same way, savate uses different colours in the gloves in order to show the level of a fighter; although, on the contrary that disciplines as the judo or the capoeira, where the fighters obtain new belts in each promotion, every fighter can use the same pair of gloves in several promotions (for that the level is not corresponding directamente with the colour of the gloves that are used but with that is established in the licence). The beginners begin without colour and the different exams of promotion permit them to be promoted to blue, green, red, white and yellow in that order. The competition is restricted for the red gloves and higher; each federation has the possibility to establish the conditions as little as possible for teaching this sport. In France, it is necessary to have the yellow glove in order to being able to gain the degree of instructor ("moniteur") and the silver glove in his technical category in order to obtain the title of teacher ("professeur"). In other lands as Mexico, all technical degrees from the green require an evaluation on subjects of helping in teaching in order to being able to increase the development of that art.
