Spending on K-12 education across the United States and across local school districts has long been characterized by great disparities—disparities that reflect differences in property wealth and tax rates. For more than a quarter-century, reformers have attempted to reduce these differences through court challenges and legislative action. As part of a broad study of education finance, the committee commissioned eight papers examining the history and consequences of school finance reform undertaken in the name of equity and adequacy. This thought-provoking, timely collection of papers explores such topics as: What do the terms "equity" and "adequacy" in school finance really mean? How are these terms relevant to the politics and litigation of school finance reform? What is the impact of court-ordered school finance reform on spending disparities? How do school districts use money from finance reform? What policy options are available to states facing new challenges from court decisions mandating adequacy in school finance? When measuring adequacy, how do you consider differences in student needs and regional costs?
