The Tennessee School Finance Equity Study was begun in 1978 to review the equity and adequacy of Tennessee's Public School Finance Program. Changes in the structure of the Tennessee Foundation Program (TFP) did achieve greater equity in the amount of funds local districts obtained from the foundation program even though the residence of the students was still a determining factor in the amount of revenue going into their schools. Instructional expenditures exhibited a decrease in equity for both the areas of property wealth and sales tax revenue. A study conducted in 1988 to assess the equity of school finance in Tennessee pointed out that local option sales tax revenue accounted for the greatest variability of local teacher positions beyond the foundation formula. The property assessment, personal income, or net indebtedness of the district did not have the impact on the variability of locally funded teachers. Variation in local option sales tax revenue rendered its use in the financing of public education inequitable across the school districts of Tennessee. The availability of locally funded teaching positions varied according to the magnitude of the individual districts' financial ability. Information tables show the Pearson Product Moment Correlation coefficients for local teaching positions, local sales tax, and personal income. Regression and GINI coefficients are also illustrated in tabular form. (ALL)
