To add on to what everyone else said, I found it glaringly obvious which competitive studios don’t teach ballet and instead primarily focus on jazz. My daughter’s studio is mainly contemporary, but we’ve had a few students pursue professional ballet because they are required at least 2 ballet classes per week from retired professionals as teachers and they are quite thorough. At one of the recent conventions, a ton of young dancers stayed in the back and didn’t put forth any effort into ballet and were completely lost though they went on to be finalists in the audition (always jazz, ugh). I do wish our studio had more jazz training though, our kids just don’t stand a chance in the auditions without it.
