The U.S. District Court ruling in Rodriguez vs San Antonio Independent School District, which struck down Texas' school finance system as inequitable and unconstitutional, provided the impetus for publishing this interim report. The report documents the growing cost of State-supported public school programs--the primary concern prior to the Rodriguez decision. It also provides preliminary estimates of the potential cost of equalizing fiscal resources among the school districts in the event the Rodriguez decision should be upheld by the Supreme Court of the United States. One section is devoted to a discussion of full State funding as an alternative method of finance, and examines the concept's costs and problems. (Author/JF)
