M.,
I think you are on to something! Why not ask the community for ways to cut costs? Why not ask the students?
Sometimes it is so hard to see the big picture when you are in it. Talk to the Superintendent and the PTO/PTA president. Suggest that you are willing to spear-head a coallition to save money from other sources to reinstate the buses. It may take half the year to do it, but it is worth the effort.
This is what schools I've worked in have done:
* one case of paper per teacher, per semester...or less depending on how many students there are.
* all copies have to be double-sided or paper has to be mostly used before discarded (ie. students write on backs of one-sided paper).
* parents "rent" textbooks for each school year and pay for damaged books
* teachers are not allowed to have coffee pots or refrigerators to drain electricity
* lights are put on motion activation switches
* digital thermostats that regulate temps...and temps are kept at appropriate levels...not too cold, not too hot
* part-time janitoral staff....teachers and students kept room clean and put garbage bags outside of doors to be picked-up at end of day, students cleaned the boards, and floors vacuumed two times a week.
* drawing the heavy curtains closed at night.
Ask where all of the money is going. Assign people to investigate each category. Send older kids to interview everyone involved and create a report. The more you involve the kids and teachers, the better chance you have of doing what you need to!
PTO/PTA's can really make a difference. They can help fund teacher's supply needs, library books, etc.
Look at grant money that is out there!!! Everyone thinks that it takes a special person to write for grant money, it doesn't!
Write a letter to the editor of your local paper and ask the readers for suggestions to save the school district money. Done in a positive way, you can move mountains!
Good luck to you!
