The Chalkboard Project / Oregon Department of Education:

When the Chalkboard Project conducted the most extensive statewide polling ever of Oregonians on education issues and priorities, 65% said they would have greater confidence in K-12 schools if they could easily find standardized budget information they could compare and contrast.
People want to know where their money is going, and they want that information in a straightforward manner that is easy to understand.
The Open Book$ Project aims to provide ordinary Oregonians with an open, simple look at where K-12 dollars really go. Audited data is supplied by the Oregon Department of Education in cooperation with Oregon’s 198 school districts.
Open Book$ is funded by the Chalkboard Project, a non-partisan, non-profit initiative of Foundations For A Better Oregon. Launched in early 2004, Chalkboard exists to inspire Oregonians to do what it takes to make the state’s K-12 public schools among the nation’s best, while restoring a sense of involvement and ownership back to taxpayers. Chalkboard aims to help create a more informed and engaged public who understand and address the tough choices and trade-offs required to build strong schools

The Portland School District spent $443,634,000 in 2004/2005 to educate 47,674 students ($9,306/student) while the Madison school district spent $317,000,000 to educate 24,710 students (12,829/student) during that same year.
A number of our local politicians have visited Portland over the years in an effort to learn more about their urban and economic development plans.
