Thank you everyone,
I suppose she just needs to go along and see what she thinks. She has gotten quite far in her AAD exams but as my thread has demonstrated not many people have heard of it. It does cover ballet, tap, modern and acrobatics and she studies all of them. The first month is free at the school she has a place at so we have nothing to lose. Her GCSE dance teacher recommended she do RAD. I don't know how much it would affect any college applications next year if she continues with AAD or if they will offer places solely on auditions.
It's so hard trying to do what is right for her
