In this paper, a companion piece to "Strategic Designs: Lessons from Leading Edge Small Urban High Schools" (ED544382), the authors analyze small high school spending in three urban districts--Baltimore City, Boston, and Chicago--to understand whether it is higher than in larger schools; if it is, why it is different; and the policy considerations connected to small school spending. Specifically, they examined two key questions: (1) How much do districts spend to operate small high schools? and (2) How do patterns of resource use in small high schools differ from patterns of resource use in larger high schools? They detail the methodology they used to address these two questions and present a discussion of findings, policy considerations, and recommendations for how school and district leaders can approach small school resource use and funding. Two appendices present: (1) Data Request; and (2) Coding Scheme for Resource Use. (Contains 25 endnotes and 11 figures.) [For the executive summary, see ED544391.]
