Let's say you have three classes and three instructors. The classes are beginner, intermediate, and advanced. The instructors are the Junior Instructor, Senior Instructor, and Chief Instructor (Master, Professor, Owner, etc.). There are 6 possible ways this can work. Let's write these out based on the template: Beginner Instructor - Intermediate Instructor - Advanced Instructor. Junior - Senior - Chief Junior - Chief - Senior Senior - Junior - Chief Senior - Chief - Junior Chief - Junior - Senior Chief - Senior - Junior Let's look at each class: Beginner Class The Chief instructor will have the most experience working with beginners. If his primary class is the beginner class, then all newcomers will come to know him early on. He's also going to be the best at helping newcomers, due to his experience teaching. On the other hand, the Junior Instructor will have the largest skill gap with this class, so it might be the class he has the most authority in. Any mistakes he makes in teaching will be ironed out in later classes by more experienced instructors. The Senior Instructor has more experience working with beginners than the Junior Instructor and is less likely to make mistakes that will cause a beginner to quit. (I made plenty of those mistakes when I started teaching). In my opinion, they fit here best if the Junior Instructor is a bad fit, and the Chief Instructor is a better fit somewhere else. Intermediate Class We'll come back to this one. Advanced Class The Chief Instructor will have the biggest skill gap compared to the other instructors for this class. The Junior Instructor may not be much better than the other students, and not have much to offer. The Junior Instructor will have the smallest skill gap, and may even be a similar rank and experience. However, the advanced class should be full of students who have the tools to work with more independence, and may just need gentle pushes from a Junior Instructor. The Senior Instructor will have a bigger skill gap than the Junior Instructor. Like the beginner class, they are a good fit here if the Junior Instructor is a bad fit, and the Chief Instructor is a better fit somewhere else. Intermediate Class (revisted) I kind of feel that both of the middle-of-the-road options (the senior instructor and the intermediate class) sort of become the catch-all from the end groups. However, there may be specific reasons to have someone do this class: Chief Instructor - will have the best experience at molding the intermediate students to become advanced levels. Also a good idea to introduce them here if they weren't introduced at the start. Junior Instructor - this might be a good fit if he's too inexperienced a teacher to run the beginner class, and too inexperienced a martial artist to run the advanced class. Senior Instructor - The senior instructor might fall here if the fit is best for the other two in the other two classes. I know, I'm way over-analyzing this. It's just something I've been curious about. In particular, the question regarding whether the junior instructor would be better fitted for the beginner or advanced class.
