Millais School is a girls' comprehensive school for students aged 11–16 situated in Horsham, West Sussex and an Outstanding School following an Ofsted inspection in 2010. There is no sixth form and the number on roll is 1495. In July 2011 the school became a National Teaching School, one of only 100 in the country. The school's catchment area serves Horsham, and the villages bordering the town. The Headteacher is Mr. L. C. Nettley, and the two Deputy Heads are Mrs S.Springer and Mr. M. Sutton. Mrs. E. Barnes is the Chairman of Governors.
A new uniform was introduced in 2007 to year 7 and was gradually integrated throughout all years, becoming compulsory for all students in the academic year 2009/10. The old uniform of a bottle green jumper and skirt with a light peach blouse and blue / green striped tie was changed to a white shirt, black jumper and green tartan skirt. An option of bottle green trousers was also created.
The school has one of the highest pass rates in Sussex and always produces outstanding exam results. During the Spring Term of 2010, the school was subject to an Ofsted inspection and was judged to be an Outstanding School. 
Millais has also had an exceptional reputation for having extremely successful hockey teams for years. Their success carried them to Nationals and they continue to play other private schools around the country.
The school's history can be traced back to 1928, around which time, the Oxford Road Senior School opened. This was a co-educational school which, in 1932 had an average attendance of 208: 116 boys and 92 girls; by 1938, this number had risen to 294: 153 boys and 141 girls. After 1944, it was split into Horsham secondary boys' and girls' schools.
As Horsham Secondary School for Girls, it received pupils from Broadbridge Heath, Slinfold, Southwater and Colgate in 1951. In 1958, it moved to its current location on Depot Road, around the corner from the site of the Boys' school, which had moved to Comptons Lane four years previously. Both schools were renamed as The Forest School, and the boys' school still retains this name.
In 1976, the school became a comprehensive, and the following year was renamed to its current name. In 1980, there were 1,097 girls on roll.
In September 1996, it was designated a language college, and currently teaches six languages: French, Spanish, German, Italian, Japanese and Chinese. Students are taught French and one other language for their initial three years and must then continue at least one as a full course GCSE in their final two years at the school (though many also continue a second language as either a shortcourse, accelerated or full course GCSE).
In 2006, a Millais became a training school, and recently opened Mitex: a training facility for staff from local schools.
The connection to the Millais family
The school is named after John Everett Millais and his initials J E M as used in his monogram are incorporated into the logo. Although John Millais has no Horsham connection, his son, the wildlife artist, gardener and travel writer John Guille Millais, lived the final thirty years of his life in a house called Compton's Brow less than a mile from the school.
