At a glance
Altrincham Grammar School for Girls is a large selective girls' grammar school for ages 11 to 18 on Cavendish Road in Bowdon, Altrincham. Founded in 1910, it presents itself through three simple values - curious, kind and courageous - and its school material links academic ambition with sport, culture and service to the wider community. The roll is about 1,384 pupils, so the sixth form is a substantial part of daily school life rather than a small add-on.
The curriculum is deliberately broad in the lower school. In Key Stage 3, pupils study English, mathematics, science, humanities, art, drama, dance, music, PE, design technology, computing, religious studies, citizenship and two modern foreign languages from French, German and Spanish. Science separates into biology, chemistry and physics in Year 9, and the GCSE structure keeps the EBacc strongly in view through history or geography, at least one language and separate or trilogy science. Sixth formers usually build a programme of three A levels, with scope for a fourth, plus options such as EPQ and Core Mathematics.
AGGS has the feel of a school where participation matters. The published clubs list runs from Model United Nations, politics, debating and first aid to art, computing, music and subject support, and the curriculum page explicitly treats trips, Duke of Edinburgh, fundraising, mentoring and representation as part of pupils' development. The site material also highlights library, art, design and science spaces, which matters for a school whose offer is as much about sustained academic habits as headline results.
Year 7 admission is through the Trafford Grammar Schools Consortium. The published admission number is 204, and the current route uses GL Assessment papers covering mathematics, verbal reasoning and non-verbal reasoning. Passing the test makes a candidate eligible; places are then allocated through the school's oversubscription order, including looked-after children, pupil-premium categories, sisters and catchment before distance is used. Recent official benchmarks underline the academic standard: Ofsted Outstanding, +1.01 Progress 8, 100% grade 5+ in English and maths, and 62.4% AAB or better at A level.
