Non-performer from a family of ballet professionals here. At 10, she should just love doing it. What she's doing now sounds great. And if she wants to make a career of it - fantastic!
Really serious pre-professional training starts at around 12 years old in ballet, and a bit later in other forms. Before that - from 8 to 11, children are only starting to learn the basics of turn out and core strength.
At 11 or 12, she'll need to start taking ballet seriously - at least 3 90 minute classes a week (none of this 45 minutes plus a whole lot of acro/doing the splits rubbish), plus Associate schemes to get a change in teaching and to mix with other more serious & talented dance students. Personally, I knew by then that endless pliés & tendus bored me, whereas my sibling (and my mother before her) just loved loved loved it. I kept dancing but did other things as well - nw I love plies and tendus!
Most girls know by about 15 or 16 whether they've got what it takes for the serious study of ballet. Again, other dance forms can start a little later). By that point she and you will know how she's doing, partly by observation, partly by teacher advice, partly by comparison (although don't take the comparisons too seriously).
So some things I'd do now:
- make sure her ballet training is as good as you can find locally. Did her teacher dance or train professionally? I don't count just doing loads of RAD or ISTD exams and then being a "student teacher" at the local school. I mean, did her teacher go to RBS, ENBSchool, Northern, etc etc
- Is she encouraged to try out for local Associates schemes?
- Where do older students of your current school go with their dance?
- Talk to her teacher. At 10, your DD's body is not the body she'll have at 15 or 16, but is there a good basic anatomical facility? What's her turn out like? What are the proportions of leg to torso? And so on.
Of course, there is more to a dance career than ballet. There's commercial dance, there's dance therapy, there are a number of careers which draw on intense and systematic movement training.
I haven't read the full thread (will do so now
, but you can find info at a forum called BalletCo, and there's a US based one called Ballet Pursuit. Loads & loads of excellent advice there.
My short advice: lots will change in the next 4 or 5 years but if you want to give your DD the best chance of following her dream ballet training available, and then add in other forms.
Decent ballet training will give her a skill for life. I've been doing class 2 to 3 times weekly for about 50 years. It keeps me sane & strong!
