By statutory directives, the legislature has attempted through the years to reduce disparities and improve the system. There have been good faith efforts on the part of many public officials, and some progress has been made. However, as the undisputed facts of this case make painfully clear, the reality is that the constitutional mandate has not been met. The legislature's recent efforts have focused primarily on increasing the state's contributions. More money allocated under the present system would reduce some of the existing disparities between districts but would at best only postpone the reform that is necessary to make the system efficient. A band-aid will not suffice; the system itself must be changed. We hold that the state's school financing system is neither financially efficient nor efficient in the sense of providing for a "general diffusion of knowledge" statewide, and therefore that it violates article VII, section 1 of the Texas Constitution. Efficiency does not require a per capita distribution, but it also does not allow concentrations of resources in property-rich school districts that are taxing low when property-poor districts that are taxing high cannot generate sufficient revenues to meet even minimum standards. There must be a direct and close correlation between a district's tax effort and the educational resources available to it; in other words, districts must have substantially equal access to similar revenues per pupil at similar levels of tax effort. Children who live in poor districts and children who live in rich districts must be afforded a substantially equal opportunity to have access to educational funds. Certainly, this much is required if the state is to educate its populace efficiently and provide for a general diffusion of knowledge statewide. Under article VII, section 1, the obligation is the legislature's to provide for an efficient system. In setting appropriations, the legislature must establish priorities according to constitutional mandate; equalizing educational opportunity cannot be relegated to an "if funds are left over" basis. We recognize that there are and always will be strong public interests competing for available state funds. However, the legislature's responsibility to support public education is different because it is constitutionally imposed. Whether the legislature acts directly or enlists local government to help meet its obligation, the end product must still be what the constitution commands--i.e. an efficient system of public free schools throughout the state. See Lee v. Leonard Indep. School Dist., 24 S.W.2d 449, 450 (Tex.Civ.App.--Texarkana 1930, writ ref'd). This does not mean that the state may not recognize differences in area costs or in costs associated with providing an equalized educational opportunity to atypical students or disadvantaged students. Nor does it mean that local communities would be precluded from supplementing an efficient system established by the legislature; however any local enrichment must derive solely from local tax effort. Some have argued that reform in school finance will eliminate local control, but this argument has no merit. An efficient system does not preclude the ability of communities to exercise local control over the education of their children. It requires only that the funds available for education be distributed equitably and evenly. An efficient system will actually
