Abstract: Much of the work being done by the new organization, Education|Evolving, is to help create and sustain an "Open Sector" -- a "space" in public education that is open to new schools (often charter schools) that are started from scratch by teachers, parents, community organizations and multi-school networks. Since this new model of public education may outstrip funds available through traditional sources of facilities financing, the brief examines promising emerging solutions under three headings: tapping non-traditional sources of funds for school financing; finding ways to economize and rethink the use of brick-and-mortar buildings; and, establishing real estate trusts and intermediaries. The report provides details on each of these strategies, including specific examples of how districts and schools have implemented them, and a list of additional readings on the topics.
