Thank you 2dancersmum and spannerandpony,
I agree my question is hard to answer because knowing the right standard is very vague!
My dance teacher and dance school is not ballet based so doesn't know too much about these schools. Pupils from my dance school usually choose more dance universities rather than ballet vocational schools. I have spoken to my teacher and I am going to try and audition. I will have a read through the current thread to get some more information :-)
