We are a K-4 school, around 400 students
Some things on our annual budget are:
Music and PE $1000 each (used at the teachers discretion for supplies)
Library $500 for general, $750 for RIF, $1800 for accelerated reading program (incentives, tests and books)
$150 for each certified teacher (not other wise covered in budget)
$650 for awards generally used by the counselor for grading period awards, red ribbon week, etc and another $100 per grade for grade level awards
Money for field trips-$100 per classroom
$400 for birthday bags give to each student on bday
$750 for our reading lab, which covers reading recovery,
Now in the past things we have paid for that are not in the annual budget are keyboards for our music program, major playground equipment, resurfacing a track we have on our playground, new basketball court, pavillon with picnic tables, benches for playground, trees, grass etc.
Our principal generally raises her own money thru candy sales, pictures, etc. She uses that for various things that we are not always aware of--I think a lot of building and grounds improvements. We have our annual budget which, for the most part, covers the same thing year after year--changes made for additions and subtractions, and amount changes by the budget committee. But we encourage teachers and staff to bring other requests and needs before the PTO. Usually when someone asks for something worth while they are not turned down, of course assuming the $ is there.
