This report is designed to familiarize the reader with current changes in State systems of public school finance. It describes in summary form the major school finance changes made in 1973 by Colorado, Florida, Illinois, Kansas, Maine, Michigan, Montana, North Dakota, Utah, and Wisconsin. State legislative sessions in these States produced substantive enactments aimed at equalizing either educational opportunity or the tax burden or both. To distribute resources to school districts equitably, States are using a modification of "district power equalizing" (DPE). Under DPE a State would guarantee the revenue yield per pupil from a given local property tax rate. Where the actual revenue raised by the rate in a district is less than the guarantee, State funds would make up the difference; where actual revenue is more, the State would recapture the excess. The recapture feature is generally either eliminated or restricted. The report also reviews property tax relief and reform efforts underway in Maryland, Oregon, Florida, Vermont, and California. It considers efforts being made to take into account the needs of tenants in property tax relief packages. (Author/DN)
