The National Center for Education Statistics (NCES) commissioned the papers in this publication to address advances in measuring education inflation and adjusting for it, as well as to examine the emergence of a new focus on school spending, rather than school district spending, as well as new, private sources of funding for public education, and a review of the status of assessing educational productivity. The first two papers continue the NCES tradition of commissioning papers to address the measurement problems of the education finance research community. The other papers examine the relationship between school district and school spending, and private sources of funding public education, of which surprisingly little is known. The final paper examines the existing attempts to estimate the cost of educational outcomes, and the implications for policymakers and researchers. Following an Introduction and Overview by William J. Fowler, Jr., papers included, in order, are: (1) Adjusting for Differences in the Costs of Educational Inputs (Eric A. Hanushek); (2) An Alternative Measure of Inflation in Teacher Salaries (Dan Goldhaber); (3) School Districts and Spending in the Schools (Amy Ellen Schwartz); (4) New Revenues for Public Schools: Alternatives to Broad-Based Taxes (Michael F. Addonizio); and (5) Modern Education Productivity Research: Emerging Implications for the Financing of Education (David H. Monk and Jennifer King Rice). (Individual papers contain references.).
