Education in the United States of America is provided in public, private, and home schools. State governments set overall educational standards, often mandate standardized tests for K–12 public school systems and supervise, usually through a board of regents, state colleges, and universities. The bulk of the $1.3 trillion in funding comes from state and local governments, with federal funding accounting for only about $200 billion. Private schools are generally free to determine their own curriculum and staffing policies, with voluntary accreditation available through independent regional accreditation authorities, although some state regulation can apply.
In 2013, about 87% of school-age children (those below higher education) attended state funded public schools, about 10% attended tuition- and foundation-funded private schools,[9] and roughly 3% were home-schooled.
