The Brazilian jiu-jitsu ranking system is a means of signifying a practitioner’s increasing levels of technical knowledge and practical skill within the art of Brazilian jiu-jitsu. Colored belts that are worn as part of the uniform are awarded to the practitioner. While the ranking system’s structure shares its origins with the Judo ranking system and that of all colored martial arts belts, the Brazilian jiu-jitsu ranking system grew to incorporate unique aspects and themes. The system has minor differences from Judo in areas such as a division between youths and adults and the issuance of stripes and degrees. Some distinct differences have become synonymous with the art, such as a marked informality in promotional criteria, a focus on a competitive demonstration of skill, and a conservative approach to promotion.
