I happened to sit next to the Curriculum Coordinator (20+ years in that District) for a large, growing US School District recently ( north of 100,000 students). I found some of the comments interesting:

This district spends about $7,900 per student annually (Madison is in the $12,500 range).
Interestingly, this is the 2nd time during the past 12 months that I’ve sat next to an educator on their way to a conference sponsored by curriculum publishers.
