Most American children attend district public schools funded largely by state and local revenue. Charter schools, vouchers, and education savings accounts route public funds differently, and the debate concerns both student outcomes and the purpose of a public system.
School funding comes primarily from state and local sources, with federal dollars a small share targeted mainly at low-income students and students with disabilities. Reliance on local property taxes produces large funding differences between districts.
Charter schools are publicly funded, tuition-free, and independently operated under a charter. Vouchers and education savings accounts direct public funds toward private tuition and related expenses. These are distinct mechanisms often discussed together.
Research findings vary considerably by program, location, and outcome measured. Some charter sectors show strong gains, particularly in urban settings; others show none. Voucher studies have produced mixed and sometimes negative test score results alongside positive attainment and satisfaction findings.
