Wallington High School for Girls is a large selective girls' grammar in the London Borough of Sutton, with about 1,547 pupils across Years 7 to 13. The school describes itself as a happy, purposeful and vibrant community, with high academic standards, first-class pastoral care and a strong enrichment programme.
The curriculum and sixth-form offer are supported by a broad co-curricular structure, pastoral resources, careers guidance, a library system, science-lab fundraising, student leadership and sixth-form destinations work. Wallington is also part of the Girls' Learning Trust, so its school identity sits within a wider local selective-school family.
Year 7 admission is for 210 places and has two testing stages: the Selective Eligibility Test, followed by the Nonsuch and Wallington Second Stage Entrance Examination. Candidates must pass the SET and both second-stage papers; the final score combines the second-stage marks with half of the aggregate SET mark. The policy includes top-score places, Pupil Premium priority and a 6.7km catchment-linked category.
Wallington's public data is strong: Ofsted Good, very high Progress 8, 100% grade 5+ in English and maths and a substantial sixth-form AAB figure. Its size, Sutton test structure and catchment mechanics make it feel different from smaller county grammars even where headline outcomes are similar.
