In the hand course, stick course, knife course, gun course, PAC course...An instructor can make one rank level under them.
Basic instructor can only promote their students to levels 1 and 2, No instructorships
Advanced instructor can only make a basic instructor and up to level 5
Expert instructor can make basic and advanced and up to level 8
A level 10, a so-called "master" (as in range master not martial arts masters) makes up to 9
Each level above makes a level under them.
In a way, work in the individual courses help build the time and grade for the CQC Group.
As far as the CQC Group...
Only I can make a Hand, Stick, Knife, Gun Close Quarter Combat Group rank or instructors, as each individual CQC Group level is like its own "black belt test." This is real slow going and only a few folks, maybe less than 95 hold, CQC Group rank, yet I teach over 1,000 people a year, sometimes more.
An instructor earns the right to purchase ran certificates at a discounted, "wholesale" rate and charge "retail"
