Every mother bringing her child to the Academy believes she will be an accomplished ballet dancer. You've raised your child and gone through all the trouble to hand her over, but at best she's going to dance at the back row of Corps de Ballet.
Mothers wince when they hear that. Ballerinas are very graceful when they step, but that makes them very miserable because of the pain they suffer from. Sacrifices have to be made.
Initially, there are a lot of names on the list, but then the list gradually gets shorter, for instance, if they put a list with three columns of names, you will see about ten people at most left on it by the end. There are girls who are never chosen for any parts and they usually get upset when the lists are put up. The thing is they're not very good candidates to begin with.
Training is a very stressful experience. Exams and rehearsals are a never ending process. Evaluations are stressful as well. The child is nervous because she doesn't know if her performance is good enough to be accepted. If she is turned down her self-esteem suffers. You have to be very strong mentally and physically to face up to the challenge. If you are turned down, you don't need to give up on everything.
There are many up and coming dancers in the theater. Everybody is given the opportunity to dance, but sometimes some of them have plenty of work.
