Medieval Combat Group maintains a fairly simple structure. The Instructors arrange and set the syllabus, and teach it with a bit of supervision support from the Free Scholars (advanced students) when necessary. In the course of drills, general training etc, the Free Scholars also help provide the right impetus and a good example for the Scholars (intermediate students), who do the same for the beginners when they join the main class.
Any feedback we get (whether its in class, from comments & questions, from watching people spar and seeing where problems are cropping up, or from watching people in tournaments etc) gets worked back into the syllabus and may result in a slight different emphasis on drills, or new drills to target specific problems that have been noted.
Two of the instructors also form the chair and vice-chair of the committee. Along with the treasurer and secretary, they deal with the nuts and bolts running of the group – hall bookings, events, session fees, equipment, H&S. Likewise any feedback on those gets taken into account and results in things like session fees beign revised, monthly fees being introduced, venues shifting, different set-ups for beginners courses etc.
Both sides are towards the same goal – to have a cohesive and inclusive group that teaches good applicable/effective technical fencing for 15th century longsword and messer, supplemented with a few other 15th/16th century closely related weapons/arts on occasion where the crossover will carry some benefits back across.
