In steps to further clarify and regulate promotion in sport Brazilian Jiu Jitsu, the IBJJF has just released a gradation guideline offering minimum ages for belts, years of consistent training in between each promotion, etc.
As it has been explained to me in regards to ‘dan’ or degree ranking for black belts the following applies (I believe this to be correct):
- 1-3rd Stripe – 3 years (active involvement) in between each promotion
- 4-6th Stripe – 5 years in between each promotion
- 7-8th Stripe – 7 years
- 9th Degree – 10 years
