Some great replies to Dancer123's post. I think if your dd doesn't feel ready for vocational school and you have a super local teacher (I think I know who will be doing the 10 hours a week, and if I'm right, you'll be in safe hands!) she'll be better off being where she wants to be for now. My dd only started taking dancing seriously in year 7 and was then at a local grammar school. Because she had a bit of a journey and her ballet hours gradually increased, she moved to our local comp' in year 8 and they have been absolutely brilliant at supporting her dancing, letting her off nearly a whole day a week and leaving early two other days. She has just been accepted into vocational school for year 10 and has decided it's the right time to go. Her work-load at school has increased considerably in year 9, so is struggling with all the travel to and from dance and the homework on top. One other thing she has always found hard, especially over the last year, was having little or no time to see friends outside school, as weekends are so full-on. I'm hoping this will be better next year!
We're slightly anxious about leaving her fabulous teachers, but as someone said to her recently, she needs to find her own way now and see how she copes in a vocational school environment! It's so hard to know what the right and best path is, (especially in such a precarious world as dance) but trust your instincts and time will tell. Good luck!
