Education in the United States is mainly provided by the public sector with control and funding coming from three levels: federal, state, and local. Child education is compulsory. There are also a large number and wide variety of higher education institutions throughout the country to choose from. Public education is universally available. School curricula, funding, teaching, employment, and other policies are set through locally elected school boards with jurisdiction over school districts with many directives from state legislatures. Because the US attracts talent and the best brains from all over the world, people with a hunger to learn, enjoy the US as a study destination. Because there are no cultural boundaries, people are also fortunate enough to learn about different cultures of the world as they find communities from different sections of the society within the campus.
