St Teresa's Effingham is a selective, independent boarding and day school for girls aged 2–18 in Effingham, Surrey, England, established in 1928. It is a member of the Girls' Schools Association.HistoryIn 1799, John Fuller built a mansion called Effingham Hill House on the site of another house which had been called Tibs, and this house now forms the centre of the senior school, and has been extended to provide modern facilities. In 1886 or somewhat later, Julius Caesar Czarnikow bought Effingham Hill House from Frederick Augustus Maxse, and owned it until he died in 1909. His daughter, Ada Louisa, sold it to Azalea Caroline Keyes, who in 1916 sold it to Robert Reitmeyer Calburn, who owned it until 1928. St Teresa's was founded in that house by the Religious Order of Christian Instruction (who also founded St Teresa's sister school Leweston School) in 1928 on what was originally part of a manor site recorded in the Domesday Book. The last headmistress nun retired in 1977. Since 2002, the school has been managed by a lay trust. Although there are no longer any religious sisters on staff (as of 2013-14 academic year), the school maintains its Catholic ethos and ties to the local parish, which is represented in the school's Board of Governors.An all-weather pitch and new swimming pool complex were completed in 2000 and 2003 respectively and, in September 2005, music, drama and the arts benefited from a multimillion-pound, 750-seat technologically equipped performing arts theatre hall, with new music and drama suites.
