Hi Sodor,
The Hammond is a lovely school. My DD has previously been a dance associate there and has done a couple of summer schools there. She has just been offered a place on the dance course but we are now waiting to hear about funding!
You could speak to the school, they are very approachable, and ask them.
I understand what you mean about being an oddball, my DD is a bit the same. She spends all her spare time at the dance studio or in rehearsals for shows and has a VERY few close friends at school, who aren't dancers. I absolutely believe that children like this would get on better in a place like the Hammond. Charlie already says things like, everyone is there for the same reason... because they want to dance, act, sing..... and everyone there knows how much effort and hard work it's taken them to get there. I think children thrive in an environment that they're comfortable, whatever the situation.
Hope this helps xxxx
