Ballet is not sports. If we are talking about Bolshoi and some other big names like Mariinka there are elite programs that are hard to get into. A daughter of my friend went to a ballet school in Perm - one of the best in Russia. Luckily for us there was no Kiira Korpi around. I understand that the coaching practices there may be even tougher than those in Russian figure skating.Now that makes me wonder if the same is true in Russia, too. Figure skating is big in Russia. But my impression is that ballet is even bigger, just like in North America. (?)
Unless we are talking state ballet schools there is a variety of small private schools with price tags of $50-100 per month.
