This map shows the locations of off-reservation Indian Boarding Schools throughout the United States, numbered in the order in which each began operations under government auspices. These 27 schools were fully managed and directed by the Bureau of Indian Affairs. (There were more than 300 other schools, located both on and off reservations, many of which were managed by the Bureau, but some of which received subsidies from the federal government for their operations.)
