I assumed--obviously wrongly--that if a child passed the exam and was financially in need of a bursary, it would be available. As this is not the case, what is the criterion? Is it that there is cap on the funds available and they go through each child in need of bursary in the order they came in the exam until they exhaust this money? If so, I'd have to advise my parents that it isn't just a case of passing the exam--they would have to pass quite well.
Also, while I'd agree the music scholarships are out of reach of all but the supremely talented, I'm not sure you can directly correlate grade level with music scholarship ability. The one winner I know was, if memory serves me rightly, working towards 6 when he won it five years ago. I think the music teachers awarding it can hear in someone's playing that extra something which goes beyond 'grades'. My own son has worked his way up the Birmingham orchestras, purely on audtions, is often a grade or two behind other players in the orchestra and still gets 'lead' player in many pieces because he has the quality of sound (as opposed to musical technique). While I regularly discourage parents from thinking Grade 3 will 'cut the mustard', I'd still advise Grade 5+ to go for it if their instrument teacher believes they have that extra something.
Finally, how would they know they'd need to offer a scholarship to attract a certain child before they called them to interview? Would they base it on which primary school they attend--as in independent versus state? Why do you think your own son was offered a scholarship, if you don't mined me asking. Again I'm interested because I regularly have parents asking me if their child is likely to win a scholarship and I always assumed the child would either have to be in the best 10 or so over all or that they have answered specific 'scholarship' questions. Certainly in the maths last year my scholarship boy was the only one who felt he'd answered correctly about the last five in the paper. And the two questions I gleaned from him and others were cleverly pitched so that only the very bright could have answered them yet they required no special tuition in algebra etc..
Anyway, any further info. would be appreciated for next year.
