Unlike traditional martial art styles F.I.S.T. does not have a belt system. Instead the practitioners progress through ten phases of training that build upon one another to produce, in 6 to 12 months, a person capable of fighting standing up, on the ground, against multiple opponents, unarmed or armed with various weapons including batons & knives.
Progress through the ranks is denoted by various colored t-shirts.
| Level | Shirt Color | Techniques Covered |
| I |
| stance, straight hand strikes, groin kicks, knees, target acquisition drills, stamina building |
| II |
| close range circular hand strikes, front kick, side kick, deflecting punches |
| III |
| escaping from holds |
| IV |
| surviving on the ground |
| V |
| fighting on the move |
| VI |
| multiple opponents |
| VII |
| getting off the ground and stand up grappling |
| VIII |
| defense against weapons |
| IX |
| control and restraint and use of weapons |
| X |

Sparring is entirely optional in F.I.S.T. Instructors of F.I.S.T. wear black t-shirts. Rather than wearing traditional martial art uniforms students of F.I.S.T. wear, along with their official t-shirt, sweat pants and trainers.
