Why It Matters

According to a Congressional Research Service (CRS) report titled "Funding for Public Elementary and Secondary Schools", the federal share jumped to 12.74 percent in FY2010 during the Great Recession and again to 13.73 percent in FY2022 during the COVID-19 pandemic, but settled back to 11.68 percent in FY2024. Federal education funding has fluctuated over time, spiking during major economic crises before retreating. According to a Congressional Research Service report titled "Funding for Public Elementary and Secondary Schools", the federal share of public elementary and secondary school revenue rose to 12.74 percent in fiscal 2010 during the Great Recession and 13.73 percent in fiscal 2022 during the COVID-19 pandemic before falling to 11.68 percent in fiscal 2024.

The shifts underscore the federal government's relatively limited but sometimes substantial role in financing public schools, particularly during periods when Congress provides emergency funding.

The Big Picture

Federal funding has generally accounted for less than 10 percent of annual revenue for public elementary and secondary education nationwide since fiscal 2002, with exceptions during the Great Recession and COVID-19 pandemic.

The Elementary and Secondary Education Act, which represents the largest tranche of federal funding for public elementary and secondary schools, tells a distinct story when adjusted for inflation. In constant 2025 dollars, ESEA funding has declined from $39.1 billion in FY2002 to $29.7 billion in FY2024. In constant 2025 dollars, ESEA funding declined from $39.1 billion in fiscal 2002 to $29.7 billion in fiscal 2024.

Meanwhile, total school revenues have grown substantially, driven primarily by increases in state and local funding. State and local governments together continued to provide the vast majority of public education revenue in fiscal 2024, with states contributing 45.81 percent and local sources accounting for 42.51 percent.

The federal government's share has historically increased during economic downturns and other emergencies. During the COVID-19 pandemic, Congress provided approximately $200 billion through the Elementary and Secondary School Emergency Relief Fund and other education stabilization programs, temporarily increasing the federal role in school funding.

The Bottom Line

Congress must weigh whether to reauthorize ESEA, unchanged since 2015, knowing that any federal cuts will disproportionately affect high-poverty school districts. ESEA's real-dollar decline since 2002 reflects decades of budget constraints, yet the administration's emphasis on federal spending discipline will likely intensify pressure on categorical programs serving disadvantaged students. The Trump administration faces a structural reality: federal K-12 funding represents a small but targeted lever over a system primarily sustained by state and local resources. Federal K-12 funding represents a comparatively small but targeted share of a public education system financed primarily by state and local governments. ESEA funding has declined in inflation-adjusted terms since fiscal 2002 even as overall public school revenue has increased.

Congress last comprehensively reauthorized ESEA through the Every Student Succeeds Act in 2015. The law generally authorized appropriations for ESEA programs through fiscal 2020, with those authorizations automatically extended through fiscal 2021. Although the authorization of appropriations has since expired, Congress can continue funding ESEA programs through the annual appropriations process.

Future congressional decisions over ESEA funding could have particular significance for programs targeted toward specific student populations and school districts, including Title I assistance for schools serving large numbers or percentages of children from low-income families.
