American culture - education

Education in the United States is provided mainly by government, with control and funding coming from three levels: federal, state, and local. School attendance is mandatory and nearly universal at the elementary and high school levels (often known outside the United States as the primary and secondary levels).
Students have the options of having their education held in public schools, private schools, or home school. In most public and private schools, education is divided into three levels: elementary school, junior high school (also often called middle school), and high school. In almost all schools at these levels, children are divided by age groups into grades. Post-secondary education, better known as "college" or "university" in the United States, is generally governed separately from the elementary and high school system.
In the year 2000, there were 76.6 million students enrolled in schools from kindergarten through graduate schools. Of these, 72 percent aged 12 to 17 were judged academically "on track" for their age (enrolled in school at or above grade level). Of those enrolled in compulsory education, 5.2 million (10.4 percent) were attending private schools. Among the country's adult population, over 85 percent have completed high school and 27 percent have received a bachelor's degree or higher.
