Last year I took on a violin pupil who's just turned 12. She had learned from a professional player and plays really well and sensitively, but has gaps in her general musical abilities which I'm keen to fill. She is now having individual theory lessons from another teacher as that knowledge was way behind. She had taken Grade 5 Royal Irish Academy of Music exam before she came to me but I would estimate her all-round musical level to be at ABRSM Grade 3-4. I get the impression that she has learned to play pieces at the expense of other musical aspects.
I have always supported our local village music festival, entering a pupil if they're at the right level, which is on in two weeks time. I'm not saying she has a 'tiger mother' but she has said she would like me to enter her for a festival in another town and also for the Feis Ceol, which is a high-level one in Dublin. She has even told me about the syllabus for this. My problem is that I find so much lesson time is spent on the festival pieces that I wouldn't want to do more than one a year.
To put this into context, this is from their website "Today, Feis Ceoil is an event of major significance in the development of musical talent in Ireland. To be successful at the Feis is very important in the musical career of many entrants, for many others it is a means of obtaining enhanced enjoyment from their music while also providing a yardstick by which to measure their personal standards."
