BJA belt system
The grading system we use at the University of Sheffield Judo club is defined by our governing body, the British Judo Association (you will hear people at the club refer to the BJA).
As you progress through the grades you are entitled to wear different colour belts, this gives people an indication as to your experience and knowledge within Judo.
Kyu grades
The first grades, before the famous black belt, are referred to as kyu grades ('Q' grades).
Denoted by colour, the first grade you will earn will be the sixth kyu (red belt). The last grade before black is the first kyu, who wears a brown belt.
sixth kyu: red belt
fifth kyu: yellow belt
fourth kyu: orange belt
third kyu: green belt
second kyu: blue belt
first kyu: brown belt
The current syllabus for kyu grades can be found on the BJA website along with resources for other syllabus.
Dan grades
The dan grades are the black belt wearers. The first five dan grades (all black belts) are achievable through Judo ability and knowledge.
From sixth dan and up, these grades are awarded for service to sport (coaching, reffing, representing the country etc) over a prolonged period of time.
10th dan is the highest grade, these are very rarely awarded. For example there are currently two UK 10th dans (July 2018).
