Rugby School is a co-educational day and boarding school in Rugby, Warwickshire, England. It is a registered charity and is one of the oldest independent schools in Britain. The influence of Rugby and its pupils and masters in the nineteenth century was enormous and in many ways the stereotype of the English public school is a reworking of Thomas Arnold's Rugby. It is one of the original ten English public schools defined by the Public Schools Act 1868 and one of the most famous and expensive schools in the country. "Floreat Rugbeia" is the traditional school song. Rugby School enrolls boarding and day students, with a total student enrollment of 800 in day student grades 4 to 12.
