Quick Definition
Professor is the title Brazilian Jiu-Jitsu students use for a black belt instructor, taken directly from the Portuguese word for teacher.
What is a professor?
In Brazilian Jiu-Jitsu, professor is an honorific used for the instructor who runs the class. The word comes from Portuguese, where it simply means teacher, without the split between grade-school “teacher” and university “professor” that English makes.
Rank on its own doesn’t hand someone the title. Under the belt-ranking system used by Gracie-affiliated schools in the U.S., professor covers black belts holding the 2nd through 6th degree, above plain “instructor” and below master and grand master. Ralph Gracie, a 3rd degree black belt, and Renzo Gracie, a 4th degree, both carry the professor title under that system.
The distinction from a casual “coach” comes down to two things: earned rank, and the job of actually teaching a group of students on a regular basis.
How the title is earned
The exact cutoff for professor shifts depending on which organization sets the rules. The Federação de Jiu-Jitsu do Estado do Rio de Janeiro, the body that certifies Gracie-lineage black belts in the U.S., places professor at 2nd through 6th degree black belt. Rickson Gracie is listed at 5th degree under that same guideline.
The IBJJF, the largest competition federation in the sport, runs a similar but separate degree ladder. A black belt earns the 1st degree after three years, then waits three more years apiece for the 2nd and 3rd. The gap widens to five years between each of the 4th, 5th, and 6th, a long enough stretch that reaching 3rd degree (the rank several schools treat as the informal starting point for “professor”) already takes roughly nine years at black belt.
Plenty of gyms skip the degree math entirely. Some hand every fresh black belt the professor title the day they start teaching. Others save it specifically for a 2nd or 3rd degree. A handful of schools, especially ones built around a sport-first, less traditional culture, drop the title altogether and stick with coach.
Professor vs. other BJJ titles
| Title | Typical rank | How it’s used |
|---|---|---|
| Professor | Black belt, roughly 2nd–6th degree | Formal address for an instructor who teaches regularly; standard at Gracie-lineage and other traditional academies |
| Coach | Any belt, often a black belt without a formal degree | Common at sport-focused, competition-driven gyms; carries less of the rank hierarchy built into professor |
| Instructor | Black belt without a certified degree | A plain, functional title for someone teaching before they’ve reached professor-level rank |
| Master | Red-and-black belt, 7th–8th degree | Reserved for senior figures with decades in the art |
| Grand master | Red belt, 9th–10th degree | The top of the belt-ranking system, held by only a handful of living practitioners |
| Sensei | Not a BJJ rank | Borrowed from Japanese martial arts; heard at some schools informally, but not part of BJJ’s own title structure |
The line between professor and coach often comes down to a gym’s culture rather than a strict rule. Traditional, Brazilian-rooted academies tend to lean on professor and its rank ladder. Gyms built more around competition, especially ones with a nogi-focused or American coaching staff, often default to coach regardless of belt degree. Sensei is a borrowed term: it works in Japanese arts like judo and karate, but BJJ never formally adopted it, so hearing it at a BJJ gym usually reflects a student’s personal habit rather than house style.
Where the title comes from
BJJ traces much of its structure back to judo, and judo uses sensei, the Japanese word for teacher. Brazil never picked up that borrowing. Brazilian academies used professor instead, the Portuguese word for teacher, the same word applied equally to a grade-school teacher and a university lecturer.
When Brazilian black belts started teaching in the United States during the 1970s and 1980s, they brought the word along with them. In English, professor usually implies a university appointment, so hearing it applied to a gym instructor can sound out of place to newcomers. The gap comes down to language, not status: Portuguese never split “teacher” into two separate words the way English did, and BJJ’s early instructors simply kept using the one they already had.
Common misconceptions
Not every black belt gets called professor. The title tracks teaching, not rank alone. A black belt who trains and competes but doesn’t run classes typically isn’t addressed as professor, even at academies that use the title formally.
The reverse assumption is just as common: that professor automatically signals a senior, highly decorated black belt. Under the Gracie belt-ranking system, a freshly promoted 2nd degree black belt already qualifies, years before reaching master or grand master status.
The title also draws pushback inside the sport. In 2025, black belt Chris Wojcik said publicly that he’d rather skip formal titles altogether, arguing that a bow or a title doesn’t guarantee genuine respect on the mat. That tension between traditional and more casual corners of BJJ shows up regularly in online forums and gym culture alike.
Frequently Asked Questions
Do you have to call your BJJ instructor “professor”?
No. Many gyms, especially sport-focused or non-Brazilian-run academies, use coach or just a first name instead. Etiquette varies by school, so it helps to follow how current students already address the instructor.
What belt do you need to be called professor?
Under the Gracie belt-ranking system, professor covers 2nd through 6th degree black belt. Some schools apply the title to any black belt who teaches, regardless of degree.
Is professor higher than master in BJJ?
No. Master and grand master sit above professor, reserved for red-and-black and red belts with decades of experience in the art.
Why do BJJ instructors use a Portuguese word instead of an English one?
Because BJJ originated in Brazil, where professor simply means teacher. English splits “teacher” and “professor” into separate academic levels, but Portuguese doesn’t make that distinction.
Is sensei the same as professor in BJJ?
Not officially. Sensei comes from Japanese martial arts and isn’t part of BJJ’s own title structure, though some students use it informally.
