Maybe it's just the money, and how exclusionary that makes things? I worked at a K-8 school that stopped having their graduation prom for the 8th grade because it got to be such a competitive, expensive event. There wasn't a lot of fundraising, it was a dinner-dance held in a restaurant function room, involved formal dresses, tuxes, limos, photographers, flowers, etc. Only about 1/2 of the class could afford to attend, if that many, and there was a lot of sniping and gossip about family incomes, poor people, etc. Maybe it all just got out of hand and the school decided it was time to stop? Just a thought.
