Lee--
I have worked in two of the major franchise studio chains...now (years later
...I am taking lessons from a wonderful, small, privately owned studio. Here in Kansas City, the chain schools are extremely aggressive about sales, but very lackadaisical about training. They have unbelievable turnover in staff. However, they do offer free training, which is nothing to sneeze at, even if it's not at the highest standard of technique. To some extent it boils down to...how much money do you have to spend? It is lovely to spend your early years as a student...dancing n the pro/am or am divisions...but if you really want to make dancing your career then eventually (and probably sooner rather than later) you will have to teach. There is just no way for a student (even the rare one that practices) to emulate the hours of muscle memory that pros achieve...and teaching requires so much more understanding of a pattern and the associated technique. It would be ideal to find a small, successful, private studio with a small staff and excellent training. But, let me tell you, studios like that don't grow on trees! So, take what you can get...start at whatever studio will have you..just to see how serious you really are about this lifestyle...because that's what ballroom teaching is...not a job, a lifestyle choice. So, try it out first with the least risk. If you love it, then you can go job hunting...
But if you want to teach...then get on with it! Remaining a student does not really prepare you to teach in any comprehensive way. If you want this as a career then you have to jump in sometime. What it will take you 6 years to learn as a student, you can learn in one as a teacher in a reputable studio. I think that in the US (at least certainly in the midwest), what makes a successful teacher is not necessarily their dancing...but often it is their understanding of their students...their ability to relate to others...and their attitude...I've seen great dancers that no one wanted lessons from, and poor dancers who are booked weeks in advance....find your niche
You can do it, if you really want to. Good luck !!!---Mal
