The purpose of this descriptive case study was to describe the implementation of Ohio's version of the Evidence-Based Model (OEBM) state school finance system in 2009. Data sources included state budget documents and analyses as well as interviews with local school officials. The new system was responsive to three policy objectives ordered by the Ohio Supreme Court in the DeRolph lawsuit: (a) a distribution formula based on student needs; (b) elimination of phantom revenue; and (c) decreased reliance on the property tax. An examination of the distributional effects assuming full funding showed that the OEBM is designed to provide adequate funding from the state, when combined with a local property tax rate of just two percent. However, the OEBM was enacted with state appropriations far below full funding, and the new formula had no effect on distribution of state funds in 2009-10. Analysis of the distribution of all state funds for schools found that property tax reimbursement to public school districts and funding for choice schools were big competitors for the education dollar.
