Beginning in 1997, a series of Ohio Supreme Court decisions ruled that Ohio's school foundation-based funding system was unconstitutional. Despite judicially mandated reform directives, little change was made until recently when Ohio adopted a modified Evidence-Based Model (EBM) into its statutory funding scheme. Ohio's EBM is intended to remedy many of the unconstitutional deficiencies found by the courts. However, due to artificial caps and guarantees on the funding that a district can receive, the EBM has yet to impact school funding in a major way. A review of the EBM, as enacted in Ohio, describes the changes to the system, as well as the shortcomings. (Contains 92 footnotes.)
