St George's School, Harpenden (also known as St George's) is a non-selective state day and boarding school in Harpenden, Hertfordshire, England, educating students of both sexes between the ages of eleven and eighteen, with an emphasis on its Christian ethos. It was founded in 1907 as one of Britain's first mixed-sex boarding schools. The school has International School status. The School was named as the Sunday Times' 'Comprehensive School of the Year' in 2019. In 2022, the School was ranked as the 122nd best secondary state school in the country based on combined GCSE attainment and A-Level point scores. History The school was founded in 1907 by Reverend Cecil Grant, having relocated his school southwards from Keswick, Cumbria in the Lake District to the site of previous school. In 1898 Grant, who was interested in co-education, was appointed the first headmaster of the newly reopened Keswick School. Along with Bedales School the school was the first co-educational day/boarding school in England. After a number of years, difficulties with the local authority and lack of a chapel prompted a move. The Harpenden site was discovered by one of the masters, a new limited company formed and Grant together with 59 boys and girls and many of the staff moved there. The new school where pupils could live in an atmosphere closely related to family life, based on sound Christian principles was officially opened in 21 June 1907. The Harpenden site had previously been home to a boarding school for 100 boys founded by Rev. Wix in 1887. A chapel was added in 1891 and a swimming pool in 1894. The school experienced a drop in numbers, with several masters and pupils leaving, and closed in 1904. The site was briefly leased to a branch of the United Services College. In 1916 Grant founded a separate Montessori unit for pupils from 2 to 8 years of age. The initial location is unclear, but in 1924 moved to Kingston Lodge, adjacent to the school grounds. (Kingston Lodge later became Goddard House is now the music school.) In 1932 the school was renamed to St George's Children's House to attract larger numbers. Its business interests were formally merged with the main school from 1949. In 1955 it broke ties with St George's and moved to Gorselands near Harpenden common. Grant retired in 1936 and A. H. Watts took over as headmaster, leading the school
