Free school meals: academic impact unclear but benefits exist
A growing number of U.S. schools offer free meals to all students, with federal spending on the National School Lunch Program reaching $17.2 billion. Experts say these programs can improve test scores and reduce absenteeism, but a Scientific American analysis finds the academic evidence is murky. However, there are clear financial and social benefits.
Universal meal programs have expanded rapidly, with student enrollment in participating schools more than tripling since 2016–2017. Federal spending on the National School Lunch Program reached $17.2 billion between October 2024 and September 2025, funding over 4.87 billion lunches. Funding sources vary: some cities and states, like Seattle and New York, use their own budgets, while many districts rely on federal dollars. Researchers note that benefits are uneven—one study found larger test-score gains for non-poor students than for poor students in New York City, while a South Carolina analysis showed modest math improvements. However, a review of 42 studies in high-income economies found minimal effects on health, behavior, or education outcomes.
The push for universal school meals could reshape how families and policymakers view education funding. If academic gains are modest, the clearest impacts may be financial relief for households and reduced stigma around eating school food. Yet, the mixed evidence means debates over federal spending may intensify, potentially affecting millions of students who rely on these programs for daily nutrition. The outcome could influence future policy decisions, though the social benefits alone may justify continued support.
