Educational institutions for women during the 19th century typically began as schools for girls, academies (which during the late 18th and early 19th centuries were the equivalent of secondary schools), or as female seminaries. (During the early 19th century there were forms of secular higher education.) The Women's College Coalition noted that: "Seminaries educated women for the only socially acceptable occupation: teaching. Only unmarried women could be teachers. Many early women's colleges began as female seminaries and were responsible for producing an important corps of educators."
