As per notes from Grand Master Woo-Jin Jung 9th Dan, we are updating the rules regarding rank order in TaeKwon-Do Class. This applies to all black belts.
Senior Ranking and/or class line up will be awarded to the Black Belt whomever was awarded the belt rank first. Even if the persons TaeKwon-Do Birthday or Black Belt Birthday is before another, if they took time off, and did not rank up before another belt, they are now not the senior belt. Whoever tested first, is the senior belt.
If you have any questions please reach out to GM Woo-Jin Jung
