Jordan & Dylan - What does the belt mean?

Jordan moved from an orange belt a full step up to a green belt. Usually they only move kids a half step at a time, but Jordan & Jon Ryan were given a whole belt movement.....so Jordan better step up the pace. I really hope this motivates him to work on kicking butt again! He is now ranked: Gokyu

Dylan moved from a white/yellow belt to a full yellow belt. He has worked hard & we hope he continues to work hard! He is now ranked: Kyukyu
