It is a grammar school, with Richard Booth as the Headmaster since September 2016. The school is also twinned with Wallington County Grammar School for Boys, in many events due to both the schools being in the same area as each other. Girls can join the boys' school's sixth form. Around 2000 girls each year apply for 210 available places. The school is in Woodcote Green on the A237, around a half-mile north of the A2022 crossroads, at the of Sandy Lane South, Woodmansterne Lane, and . It is near the southern edge of the borough of Sutton, and the western edge of Croydon. It is only one mile north-east of Surrey, specifically Woodmansterne.
History
Wallington High School for Girls was established in 1888 by a collective of nuns. The school building has since changed many times, and now accommodates an estimated 2310 students with 210 in each year group, as well as a Sixth Form College. It was originally on Stanley Park Road in Carshalton, known as Wallington County Grammar School for Girls, the Wallington County School for Girls, Wallington County School, or the County School for Girls, Wallington. This site is now Bandon Hill primary school. It moved to Woodcote Road in 1965, the same year it changed its administration from Surrey County Council to the borough of Sutton. In the late 1970s it had around 750 girls with 150 in the sixth form. In the 1990s it became grant-maintained school.
Although the school itself is non-religious, Springfield Church uses the school premises for its worship every Sunday at 10.30. The school lies in the parish of Wallington Holy Trinity, with the nearest church being Wallington , and lies on the boundary with Roundshaw.
The Houses
Wallington has seven different forms in each year group. Each form is a member of one of the seven different houses, each named after an influential woman. Each house has two Year 11 House Captains, who are responsible for organising the annual fete and events and activities for their house. However, there will be the addition of an extra house as of the academic year of 2012/2013 and this new house will be called Curie with the house colour of Cerise. This is due to the school needing to expand in order to accommodate the growing number of primary school students leaving primary education without a place in a secondary school.
Uniform and house names
The school uniform consists of a navy and green kilt; a baby blue shirt ;a green v-neck jumper or cardigan and a navy blazer. However, students that joined the school before 2006 will not have blazers as these items were not on the school uniform regulations as of that time. Blazers also have the school logo and house name on the left-breast pocket.
