All students must train for minimum periods of time between their grade tests in order to give them time to improve and learn.
After that time, we will consider whether they've worked hard enough, have the right attitude according to the belt they'd like to test for and whether they know and can perform their syllabus well.

We will never enter a  student for grading on the basis that they've completed enough classes. KBOX is about knowledge, learning and self improvement.

     Some Notes on the Cadet System.

  • Cadets (under 16s) and Seniors follow the same syllabus until 1st Kyu.

  • 2nd and 1st Kyu syllabuses are shortened and 'watered down' slightly for Cadets.

  • A Cadet must be at least 12 years old in order to be Cadet Black (Shodan-Ho meaning 'Provisional') which is an easier version of the full Senior (Shodan) black. Cadet Black shows a student has learned basic techniques, can fight well to defend and has learned discipline, focus and trained regularly with hard work, to their best standard.

  • At 16, s/he will take the full Shodan (1st Dan) grading, and if the time between is more than two years, will take an Intermediate Shodan-Ho, a 'refresher' grade first.

  • The reason for this system is for safety purposes. We feel that, even if they show themselves to be highly capable technically, younger students are not sufficiently emotionally mentally mature, or physically matched to hold full senior Black Belts and do not fully understand the implications and responsibilities which come with holding a 'black belt' in a martial art.

  • That said, Cadet Black is a difficult, exhausting and highly revered belt, needing much practice and dedication and is given only to students who are fully deserving.

  • Cadets take all gradings included in the gold route shown below from 10th kyu.
