Up a Steep and Very Narrow Stairway

There is wide variety among dance studios in the United States, but ballet has been fundamental to most of them over the twentieth century. Ballet teachers come from a variety of backgrounds, including both professional dance careers and many kinds of teacher training. Good ballet teachers offer a progressive sequence and think about how to interact with students in the studio, whether they are teaching purely recreational or pre-professional classes. Good training can take place in less than ideal physical facilities, though the type of flooring is particularly important. Teachers should be knowledgeable about both ballet pedagogy and the business skills necessary to run dance studios. There is no one group overseeing the quality of ballet classes or the qualifications of teachers, though dance teacher organizations have tried to provide teacher training since the early twentieth century. Dance teacher organizations have also represented their members’ legal and professional interests.
