"As one who has never even walked past the front door of a franchised dance studio under any name. Where I live they don't exist. A question. Are they affiliated with the IDSF in any way. Or are they a law unto themselves answerable to only themselves."
It's almost unheard of for a d Dance studio (commercial business) to be affilated with IDSF.
A dance club on the other hand - that might be a member of a national IDSF member body.
And this is an interesting distinction: in countries where the IDSF idea is popular, the leading training organizations are dance clubs, not dance studios.
And even in countries where dance studios dominate real training, it is not chain-style studios doing it - instead, it's instrucotrs doing all the things our chain advocate in this thread keeps claiming no real instructor would ever do - such as teaching without a formalized study plan, taking money one lesson at a time, etc.
Oh, and the claim about chain instructors being "constantly" coached by world class professionals? Impossible, for the simple reason that no-world class professional viable as a teacher at that level is going to stay put enough to be "constantly" training anybody. These folks travel the world, and are probably "home" little more than 50% of the time. You want to learn from them, you get used to intermittent lessons, even if you are in "their" studio.
