For example, for us, at each rank, students must learn the tul history, various Korean terms (class commands, counting to 10, and similar items), the meaning of the color of their next belt, and various items of theory. I think that such information is valuable, because the theory helps students to better understand and apply what they are learning, and the Korean vocabulary and history helps them to better understand the culture that created TKD.
