HIGHER EDUCATION SYSTEM IN THE UNITED STATES

• Higher Educations
• Private Colleges
• Community Colleges
• Private Universities
• State Universities.

Education in the United States is mainly provided by the public sector, with control and funding coming from three levels: federal, state, and local. Public education is universal at the primary and secondary levels (known inside the United States as the elementary and high school levels). The ages for compulsory education vary by state, beginning at ages five to eight and ending at the ages of fourteen to eighteen. A growing number of states are now requiring compulsory education until the age of 18.

Compulsory education requirements can generally be satisfied by educating children in public schools, state-certified private schools, an approved homeschool program, or in an orphanage. In most public and private schools, education is divided into three levels: elementary school, middle school (sometimes called junior high school), and high school (sometimes referred to as secondary education).

Post-secondary education, better known as "college" in the United States, is generally governed separately from the elementary and high school systems.

Among the country's adult population, over 85 percent have completed high school, and 27 percent have received a bachelor's degree or higher. The average salary for college or university graduates is greater than $51,000, exceeding the national average of those without a high school diploma by more than $23,000, according to a 2005 study by the U.S. Census Bureau.
