How do you get a black belt in Jiu-Jitsu?

Each of the BJJ belt ranks has 5 levels. When you move up in Brazilian Jiu-Jitsu belts, you are given a solid-colored belt. Over time, you earn each of your 4 stripes. Every striped earned is an additional level you have mastered as a BJJ student. After you receive all four stripes, you advance to the next Brazilian Jiu-Jitsu belt!
