The belt system in Kuk Sool Won consists of:
- White: Foundation
- Yellow: Beginner
- Blue: Intermediate
- Red: Intermediate/Advanced
- Brown: Advanced
- Brown/Black (Dahn Bo Nim): Black Belt Candidate
- Black: Black Belt/Instructor
Between each full colour belt there is a stripe belt that represents the halfway point. These belts will be the colour of the previous belt, with a stripe along the length of the belt that matched the colour of the next belt.
Gradings for belts are held every three months, taking place in March, June, September, and December. Students are only invited to test if deemed ready by the instructor team and will be tested on what they have learned since their previous belt, as well as all material learned prior.
Students testing towards a Black Belt rank must also complete National Gradings, which usually take place the day before a tournament.
