I recently helped out at dd's schools junior disco for the first time(dd is in year 1, disco is for juniors only). I know the PTA see the disco as more of a service than a fundraiser, TBH I foudn this weird since IMO you should take every opportunity to make something from an event. I have been on the pre-school committee for 2 years so know how hard it is to raise even a small amount.
I thought it was odd for 2 reasons. First they charge entry(roughly £2-2.50 per child) and then the children get free squash all night and 2 bags of crisps. Secondly, that's it, apart from the disco. So they arrive, boogie, the hatch opens and they let them have drinks whenever, then they let them loose with a bag of crisps and they can come back for a 2nd if they wish
I was chatting to a friend and she said at their disco the entry price includes one packet of crisps and one cup of squash, the entry price was roughly the same. They then sell plastic glowing tatt things(rings, necklaces etc etc) sweets, extra squash, hair spraying(coloured/glitter) tattoos and have a face painter.
She said they raise approx £700 from max of 270 children. Our school only has max 120 children as they are junior only discos(infant discos have been discussed but most of the committee felt it should remain a junior privilage), but I think we could raise at least something by taking on some of these ideas.
I'm thinking of raising this with the committee and explaing that they may be missing out on some much needed money by limiting the things that happen at the disco.
So, what happens at your dc's disco?
