Westminster School is an independent day and boarding school in London, England, located within the precincts of Westminster Abbey. With origins before the 12th century, the educational tradition of Westminster probably dates back as far as AD 960, in line with the Abbey's history. Boys are admitted to the Under School at age seven and to the senior school at age thirteen; girls are admitted at age sixteen into the Sixth Form. The school has around 750 pupils; around a quarter are boarders, most of whom go home at weekends, after Saturday morning school. It is one of the original seven public schools as defined by the Public Schools Act 1868. Charging up to £7,800 per term for day pupils and £11,264 for boarders in 2014/15, Westminster is the 13th most expensive HMC day school and 10th most expensive HMC boarding school in the UK. Westminster school achieved the highest percentage of students accepted by Oxbridgecolleges over the period 2002-2006.
