The promotional scale is divided into nineteen ranks - 10 grades (Gups) and nine degrees (Dans.) The former begins with 10th grade (Gup) the lowest and ends at first grade. Degrees begin with the first degree (Dan) and end with the ultimate, ninth degree.First through third degree is considered the novice stages of black belt. Students are still merely beginners in comparison to the higher degrees. At fourth degree, the student crosses the threshold of puberty and enters the expert class. Seventh through ninth is composed of Taekwon-Do masters - the elite who fully understand all the particulars of Taekwon-Do, mental and physical.
