The Boston Latin School is a public exam school founded on April 23 1635, in Boston, Massachusetts, making it the oldest public school in America. The Public Latin School was a bastion for educating the sons of the Boston Brahmin elite, enabling the school to claim many influential Bostonians as alumni. Its curriculum follows that of the 18th century Latin-school movement, which holds the Classics to be the basis of an educated mind. Four years of Latin are mandatory for all pupils that enter the school in 7th grade, three years for those who enter in 9th. In 2007 the school was named one of the top twenty high-schools in the United States by U.S. News & World Report.
