Ethics in yoga and teaching yoga are universal. Every yoga teacher knows the fundamentals of an ethical practice. Common sense doesn't require books to be written about how to behave and teachers should have a handle on common sense. Most yoga certification programs provide an ethics agreement for teachers.
One of the first things to consider is what type of Yoga class will be taught. This may seem like a simple, maybe even insignificant thing, but in fact, it is a huge first step into balancing objectives, creating financial forecasts, and marketing plans. Some types of yoga instruction will create the need for larger spaces, translating into a larger studio, and a more expensive monthly budget. This will also mean more students are needed to cover expenses.
