Guildford High School is an all-girls independent school not far from Guildford High Street, on London Road, Guildford, Surrey. It works closely with the local independent boys' school Royal Grammar School. There are approximately 930 students from junior school to sixth form.
From the first, Guildford High School, founded by the Church Schools Company in 1888, was a progressive school. While some early girls' schools were designed to enhance the knowledge and skills of prospective governesses, Guildford High School sought to provide a feminine counterpart to the reformed public schools for boys. The current site on London Road was completed in 1893 and is still in use. During the post-World War II years, the school underwent rapid expansion. By the 1980s, student numbers had increased to over 600. Today the school has over 980 girls and is still part of the Company (now known as the United Church Schools Trust).
The school possesses a sports' centre off of the main campus. This includes an indoor swimming pool, gym, sports hall, fitness suite and social area. The main campus consists of the Senior school, the sixth form house (Morton House), Nightingale Road House, and the Junior school. Harper House was bought and added to the premises, also enlarging the gardens, in August 2011. The garden of the original Nightingale Road House were converted into a social area when the site was acquired in 2006.
