Eton College is a 13–18 independent boarding school for boys in the parish of Eton, near Windsor in Berkshire, England. It was founded in 1440 by King Henry VI as "Kynge's College of Our Ladye of Eton besyde Windesore", as a sister institution to King's College, Cambridge, making it the 18th-oldest Headmasters' and Headmistresses' Conference school. Eton's history and influence have made it one of the most prestigious schools in the world.Following the public school tradition, Eton is a full boarding school, which means pupils live at the school seven days a week, and it is one of only four such remaining single-sex boys', boarding-only independent senior schools in the United Kingdom . The remainder have since become co-educational: Rugby , Charterhouse , Westminster , and Shrewsbury . Eton has educated prime ministers, world leaders, Nobel laureates, Academy Award- and BAFTA award-winning actors, and generations of the aristocracy, having been referred to as "the chief nurse of England's statesmen."Eton charges up to £42,501 per year . Eton was noted as being the sixth most expensive HMC boarding school in the UK in 2013-14, however the school admits some boys with modest parental income: in 2011 it was reported that around 250 boys received "significant" financial help from the school, with the figure rising to 263 pupils in 2014, receiving the equivalent of around 60% of school fee assistance, whilst a further 63 received their education free of charge. Eton has also announced plans to increase the figure to around 320 pupils, with 70 educated free of charge, with the intention that the number of pupils receiving financial assistance from the school continues to increase.
