Fraternities and sororities exist for high school students as well as college students. Like their college counterparts, most have Greek letter names. Although there were countless local high school fraternities and sororities with only one or two chapters, many secondary fraternities founded in the nineteenth and twentieth century in the United States grew into national organizations with a highly evolved governing structure and regularly chartered chapters in multiple regions. Many of the local chapters of these national fraternities were not tied to (or affiliated with) individual high schools but were instead area based, often drawing membership from multiple high schools in a given area.
