I've been toying with something like this, mostly because I'm okay with folks not having a uniform first class (all the schools I trained in required a uniform to start first class). Now I need some delineation of when a student must have a uniform. Having them earn the right to wear it would fit with this, as it should take about 4 classes to get to that point, by which time I'd want them to have a uniform.Not an Aikido practitioner however, in the arts we instruct that has a belt rank structure students must earn their white belt.
They need to know the school's basic etiquette, basic punches, elbows, knees, kicks, falls, rolls, getting to a standing position from the ground, and some footwork. We don't expect it to be refined just know what we are asking for and a good attempt to do it. It is amazing how excited Adults as well as the youth become with earning that first belt.
