Most people coming into the ballroom dance lessons for the first time will have little if any idea that an instructor is experienced or not. They likely figure that if they are going to attend lessons that the instructurs know more then they do, and that's likely correct no matter what the teacher's experience level is. I am thankful I was as lucky to start out with an experienced dance teacher, and she is educated as a teacher, too. (That is not to say this is a must because I am sure there are plenty of those who have a teaching degree that are not good at instructing as well as plenty of dance instructors who are outstanding without a teaching degree.) However, when one is no longer new to dancing lessons, it likely becomes more important as to who one has as a teacher. Example, now that I know a little, no matter how darn little that may be, when I seek someone out to teach me Argentine Tango I'll be looking for an instructor who has a positive reputation with experience.
