The idea of having a belt system in no-gi Brazilian Jiu-Jitsu, despite not having a traditional belt worn as in gi BJJ, indeed sparks a lively debate among practitioners and enthusiasts. Here are several reasons why a belt system might still be relevant in no-gi BJJ:

1. Standardized Progression and Recognition

• Skill Levels: Belts provide a clear and standardized system of progression that reflects skill level, knowledge, and experience. This helps instructors assess and recognize the progress of students in a structured manner.
• Motivation: For many practitioners, belts serve as milestones and motivational tools. They give students clear goals to aim for and a sense of accomplishment when those goals are achieved.

2. Educational Structure

• Curriculum Organization: Belts help organize a curriculum in a way that ensures foundational techniques are mastered before more advanced techniques are introduced. This sequential learning is crucial in martial arts to build competence and prevent injuries.
• Teaching Roles: Higher belts often take on informal teaching roles in class, assisting less experienced students. This hierarchy can facilitate a better learning environment and foster a sense of community and mentorship.

3. Competitive Parity

• Tournament Classification: In competitions, belts are used to categorize fighters into divisions, ensuring matches are fair and competitive. This helps maintain a level playing field where individuals compete against others of similar experience and skill level.
• Cross-Discipline Recognition: Many no-gi tournaments and other grappling sports recognize BJJ gi rankings as indicative of a competitor’s experience and skill level, helping to organize events and match-ups.

4. Cultural and Historical Traditions

• Tradition: BJJ is deeply rooted in tradition, and the belt system is a significant part of its heritage. Even in no-gi, many schools choose to maintain this tradition as a nod to the art’s history and lineage.
• Respect and Discipline: The discipline and respect taught in martial arts are often symbolized by the belt system. It teaches students to respect the journey and the achievements of those who have advanced through the ranks.

5. Commercial Aspects

• Business Model: While there’s a commercial aspect to martial arts schools (like any educational institution), the belt system also helps structure classes, seminars, and promotions in a way that can be financially sustainable while providing value to students.

While wrestling and other combat sports thrive without a belt system, using belts in no-gi BJJ can offer benefits beyond just commercial incentives. It provides a framework for progression and learning that aligns with the educational goals of martial arts. However, the necessity and value of belts can vary depending on personal and school philosophies, and as the sport evolves, these practices might too.
