I forgot to mention that i do ITF. and belts went white, white with yellow stripe. yellow, yellow with green stripe. green, green with blue stripe. blue, blue with red stripe, red, red with black stripe, black. and depending on your age when you start, its either one or 5 tests between white and white with yellow stripe. so yeah. all of that was 6 years for me. I did a lot of breaking but my instructor believed in letting kid's bones grow fully rather than possibly damaging them while they are still growing. my best was 2 inches of solid pine with one side kick and the same thickness with a back kick when i was 11. so yeah.
