Castleton University, formerly known as Castleton State College, is a public liberal arts college, located in Castleton in the U.S. state of Vermont. Castleton has an enrolment of 2000 students and offers more than 30 undergraduate programs, as well as master's degrees in education and accounting. The college is accredited by the New England Association of Schools and Colleges. Castleton University traces its history to the Rutland County Grammar School, chartered by the Vermont General Assembly on 15th October, 1787.The Grammar School was a regional school, preparing young men for college through instruction in traditional academic subjects such as Latin and Greek. In 1829, a three-story brick building costing US$30,000 was constructed on a small hill south of the village. Principal Solomon Foot (1826–1829), who would go on to be President pro tempore of the U.S. Senate during the Civil War, was the driving force in this expansion of the school. The Seminary Building (eventually known as the Old Seminary Building) was the most impressive structure in the village, but expensive to maintain and often too large for the school's struggling enrolment. Castleton Medical College (1818–1862) was also located in the village. It graduated 1400 students, more than any other medical school in New England at the time. Although Castleton Medical College and Castleton Seminary were separate institutions, they often shared faculty. Today the former medical college building, known as the Old Chapel, is the oldest building on the campus. The first female principal was Harriet Haskell (1862–1867). She had attended the Seminary as a child, took classes at Middlebury College without being permitted to matriculate, and then attended Mount Holyoke Female Seminary, which was not yet a college but offered a college-level curriculum for women. Although Haskell was in her 20s when she served as principal, the school flourished under her administration. With her departure to be principal of Monticello Ladies Seminary in Godfrey, Illinois, Castleton Seminary went into decline. Built in 1821, Old Chapel (Castleton Medical College Building) is the oldest building on the Castleton campus. University hired staff with advanced degrees, and broadened her students' exposure to the world by bringing people such as Helen Keller, Robert Frost, and Norman Rockwell to Castleton. Woodruff was the first and only Vermonter to become president of the National Education Association. On July 23, 2015, the Vermont State Colleges Board of Trustees voted unanimously to change the name of the institution to Castleton University. This was far from the first time there had been a proposal to change the school's name: in the fall of 1979, the Board of Trustees proposed a name change to Southern Vermont State College; the proposal was never acted on. Nearby Rutland plays host to the Castleton Polling Institute, as well as a professional development centre for educators and entrepreneurs. In September 2016, the university opened Foley Hall, a two-floor residence, in collaboration with Green Mountain Power and Efficiency Vermont that provides housing for students.
