While the state's appropriations to public education have increased over time, most of the increases in public education spending have come from local tax revenue, which is entirely funded by the school district property tax. As a result of the increased burden on local property taxpayers to support public education, the state's share of education funding has significantly declined and local school boards have had to raise property taxes to meet their needs. In 1985, the state share was 52.2 percent of local and state education spending. Almost twenty years later, the state share is projected to comprise only 36.2 percent in 2004 and 36.3 percent in 2005 of state and local revenue for Texas public schools.
