Overview

Southend High School for Boys is a selective boys' grammar in Southend-on-Sea, serving ages 11 to 18. The school presents itself as a high-expectation grammar where pupils are happy and prosper, and where academic standards are sustained through structured support and guidance. The school has about 1,325 pupils on roll, including the sixth form.

The academic offer is broadest in the sixth-form material. SHSB describes a sixth form of around 450 students based in a dedicated, purpose-built centre with its own common room, canteen, study rooms, ICT suite, pastoral office and a study area in the main school library. Students normally choose four A levels, with the Extended Project Qualification available, and the school links recent results to Oxbridge and Russell Group progression.

The same sixth-form pages give the best view of wider school life: personal development, health and wellbeing, cooking, mindfulness, volunteering in local primary schools, team sports and Duke of Edinburgh all appear there. Drama, sport and community volunteering also appear, so the school reads as academically ambitious but not narrowly classroom-bound.

Year 7 admission has 180 places and uses the CSSE 11+ route: a 60-minute English paper with additional reading time and a 60-minute mathematics paper, standardised and weighted equally. SHSB reserves up to 150 places for applicants in SS0-SS9, with preferential-consideration places inside and outside the area, and the remaining places allocated by marks under the published policy. Ofsted judged the school Outstanding in June 2024; GOV.UK shows +0.74 Progress 8, 98.9% grade 5+ in English and maths, and 26.7% AAB or better at A level.

The report describes a highly academic school with a strong sense of community, expert teaching, respectful conduct, extensive enrichment and pupils who see themselves as a positive force for change.

Examples included Year 10 work on mathematical proof and sixth-form art that showed considerable depth, supported by passionate specialist teachers.

  • Sixth form provision: The sixth form shares the school's Outstanding judgement. The available report evidence points to demanding academic work, especially in art, and to the same wider culture of expert teaching, strong support and enrichment that helps pupils pursue their interests fully.
