Quick answers for parents

• Kids ages 4 to 15 use the IBJJF youth belt system (13 ranks). [1]
• Teens in the year they turn 16 move into adult belt colors (white, blue, purple, brown, black). [1]
• IBJJF minimum age for blue belt is 16, and the same minimum age applies to purple. [1]
• For ages 4 to 15, IBJJF lets coaches judge time at each belt. [1]

1) Which Belt Track Fits Your Child?

Kids Belts: Ages 4 to 15

IBJJF lists 13 belt ranks for athletes ages 4 to 15. [1]

Teen Belts Depend on Age

• Ages 13 to 15: still in the kids belt system. [1]
• Ages 16 to 17: may be in adult belt colors (white, blue, purple). [1]
• Age 18+: adult belt colors continue (white through black). [1]

How IBJJF Counts Age

IBJJF uses the current year minus birth year. A student counts as 16 in the year they turn 16. [1]

Minimum ages by color group (IBJJF)

• Grey group: ages 4 to 15
• Yellow group: ages 7 to 15
• Orange group: ages 10 to 15
• Green group: ages 13 to 15

These rules set the age range for each belt group. A coach still judges when a student is ready. [1]

3) When does a teen become a blue belt?

• Blue belt: 16 or older
• Purple belt: 16 or older
• Brown belt: 18 or older

Age sets the first gate. A coach still judges skill before giving a new belt. [1]

4) Stripes vs degrees: what do they mean?

Many schools use stripes on a belt. IBJJF calls these degrees in its youth posters. Each mark shows a step within a belt stage. [1]

• Belts: major stages
• Stripes/degrees: progress within a stage

5) How often do kids get stripes or degrees?

Schools can use different stripe plans. IBJJF lists three sample youth systems for ages 4 to 15. Coaches choose what fits their school. [1]

One Mark Each 3 Months

• 3 degrees inside a belt
• 4th degree moves to next belt color
• Poster cycle shown as total 1 year

[3]

One Mark Each 4 Months

• 2 degrees inside a belt
• 3rd degree moves to next belt color
• Poster cycle shown as total 1 year

[4] Learn the class words.

One Mark Each Month

• 11 degrees inside a belt
• 12th degree moves to next belt color
• Poster cycle shown as total 1 year

Special white/grey-white note

One monthly IBJJF model splits a year in two. It lists 6 months at white and 6 months at grey-white. This is a sample model. [5]

6) How kids earn the next belt

For ages 4 to 15, IBJJF lets a coach judge time at each belt. It sets a minimum age for each color group. Sandy looks at skills over time to judge readiness. [1]

Safe Partner Work

• Training with control
• Pausing when asked
• Give your partner a task at a calm pace

Functional Grappling

• Solve a task as your partner adds resistance
• Learn skills in more positions

Changing Your Plan

• Try a new move when the first is blocked
• Spot a new problem and ask for help

Choosing Your Own Moves

• Choose moves that fit your body and the task
• Find your next move with less coach help

Class time gives students chances to learn. Sandy looks at the skills he sees in those rounds. Attendance alone earns neither a stripe nor a belt.

7) Competition note for older teens (16+)

For IBJJF events, check the age, belt, and time-at-rank rules. Ask your coach how they apply to your teen.

IBJJF minimum time rules that start at age 18+

• Blue belt: 2 years (with listed exceptions)
• Purple belt: 1.5 years (with listed exceptions)
• Brown belt: 1 year (with listed exceptions)

IBJJF lists exceptions for some youth and teen belt histories. It also has rules for adult World Champions. Read the full current rules with your coach. [1]

9) A Short Belt History

Modern belt ranks grew from Judo. The IJF lists early dan grades from 1883. The belt system changed over time. [6]

Some histories credit Mikonosuke Kawaishi with adding more belt colors in Europe in 1935. The colors helped show steps in a student's progress. [7]
