A selective boys grammar school in Southend-on-Sea, Essex, serving ages 11-18 with a sixth form and around 1,325 pupils on roll. Southend High School for Boys serves boys aged 11-18 and keeps a full sixth form on site. Current published roll and admissions data point to around 1,325 pupils on roll and 150 Year 7 places.
From a family point of view, admissions are likely to be one of the most important parts of the picture. The current route includes CSSE, with 150 places available in Year 7 and demand that currently looks high by grammar-school standards. Catchment or distance rules still matter at allocation stage, so this is the kind of school where families need to read the admissions policy carefully rather than rely on headline scores alone.
The academic side of the school is backed by enough published data to give families a useful starting point. The latest published Ofsted judgement is Outstanding. Recent official performance measures show Progress 8 at 0.74 and Attainment 8 at 73.9. 98.3% of pupils achieved grade 5 or above in English and maths in the latest stored GCSE figures. In the sixth form, 26.7% of entries were awarded AAB or better at A level. Destinations data also suggest strong progression after sixth form, with 68% moving into higher education.
Published school information highlights facilities such as Library. The wider offer currently includes Drama. For many parents, the presence of a sixth form is part of the attraction, because it gives able pupils the option to stay in a familiar academic setting through to A level. Taken together, those features make Southend High School for Boys the kind of school that rewards careful research into travel, admissions detail, and day-to-day fit, not just headline outcomes.
