The Fiscal Factbook is a data-rich, accessible guide to how education funding works in the United States. School finance is often one of the most misunderstood aspects of K–12 policy. This publication walks readers through how money flows through the system, what it actually costs to educate students in traditional and choice programs, and how funding formulas cushion district budgets when students leave. With charts, comparisons, and key takeaways, the Fiscal Factbook equips readers to engage in more informed conversations about education spending, and how school choice fits into the broader picture.
