There is no rule to say that it does, however there are often rules to say that it doesn't - especially when schools are run by local authorities. My concert money goes into the fund used by the Parents Association and they then buy me things that I need - however we have also brought a minibus with the money (and other money raised) which I use sometimes so I have no problem with this. In my last school the money went into a "fund" which was used to pay for drama productions and equipment for the school hall. I would be cautious about mentioning "DJ" concerts - obviously it depends on the school, however I would be inclined to talk about "restoring quality performance opportunities for a wide range of students" and "reintroducing a culture of high quality performances showcasing student's own talents". Yes, focus on what will inspire students but also remember you need a forum to which parents can come and be impressed by what you do and have achieved with their little ones - this in turn feeds back to the school and makes you even more indespensable. Finally, remember that there will be students who play instruments and do grades or sing (even if they are a small minority) who may feel uncomfortable performing in a concert where DJ music has whipped the crowd into a frenzy - I have kind of made this mistake by putting on loud concerts with big PA and lighting which made any classical or acoustic contributions look a bit small. I feel guilty about it often - I had not properly considered the needs of all students at the time. Good luck with your application, however. Sounds like this school is in need of someone with drive and imagination.
