I love Val's school. Here's a few things I would add:
- recycle and compost as much as posssible
- edible garden, teaching kids to grow and prepare some of their food
- no prepackaded cookie/cracker snack bags. Fresh fruit/veg/yogurt/cheese for snack whenever they need it
- no competetive parents
- access to a wooded area and/or a creek for outdoor classroom activities
- diverse racial/cultural/ecomonic respectful environment

Warning: sleep deprived
