The United States education system is divided into three levels: primary, secondary, and higher education. Primary education is typically provided through kindergarten through fifth grade. Secondary education is provided by middle and high schools and typically covers sixth grade through twelfth grade. Higher education includes post-secondary education such as vocational schools, community colleges, and universities. Each state is responsible for providing primary and secondary education, while higher education is provided on both a state and private level. The curriculum in each state varies, although all states must adhere to the federal educational guidelines.
