A decades-long school funding revolution continues in the United States. The litigation sparked by the Supreme Court of California's 1971 decision in "Serrano v. Priest" continues to reshape the legal, political, and educational landscape in the United States, affecting the lives of children, parents, educators, and taxpayers throughout the nation. "Serrano"-inspired lawsuits have transformed school funding policies nationwide, resulting in billions of dollars in new funding and a notable redistribution of resources among school districts. "Serrano"-inspired litigation has changed public schools in many states to a degree second only to the transformation that followed "Brown v. Board of Education." To understand school funding litigation in the present and to better anticipate future developments, a review of the past, present, and likely future of school funding litigation is invaluable. This article briefly reviews and discusses the past, present, and likely future of "Serrano"-inspired school funding litigation. (Contains 85 footnotes.)
