This report offers an analysis of school finance litigation during 1998. It summarizes cases in New Jersey, Ohio, Arizona, Texas, Wyoming, Colorado, New Mexico, and New York. These states were sued due to failure to provide a thorough and efficient system of common schools, ineffective efforts to provide equitable financing to poorer school districts, methods of funding school facilities, and other matters. Only five states have not been sued over school-finance issues: Delaware, Hawaii, Iowa, Mississippi, and Nevada. Historically, school-finance suits have focused on the equity and adequacy of state funding, and the decisions handed down in 1997 and 1998 have followed that pattern. However, in recent years several cases have dealt with other questions such as the quality of facilities or special-education funding. The issues of what constitutes an adequate educational system and how it is defined continue to be the main battleground for distinguishing constitutional from unconstitutional systems. An appendix offers a state-by-state summary of school-litigation cases. (RJM)
