, Residents of the Edgewood Independent school district, a poor, largely Hispanic area in west San Antonio, are willing to pay for good schools. Property taxes are high -- almost $1 per $100 of assessed valuation. But because the district encompasses part of a tax-exempt Air Force base and lacks tony subdivisions, the tax rate translates into $3,596 per student. In the Santa Gertrude school district, located on the oil-rich King Ranch in south Texas, property taxes are low -- only 8 cents per $100 of assessed valuation -- but the total spent per student is $12,000.
