Families looking at Sidcup, Greater London will usually see Chislehurst and Sidcup Grammar School as a selective option for boys and girls aged 11-18, with sixth form continuing the academic journey on the same site. Current published roll and admissions data point to around 1,517 pupils on roll and 192 Year 7 places.
For parents thinking about the 11+, the admissions picture is one of the clearest differentiators here. The current route includes GL Assessment, with 192 places available in Year 7 and demand that currently looks very 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.
On current official measures, the school offers a clear academic profile for parents to weigh up. The latest published Ofsted judgement is Good. Recent official performance measures show Progress 8 at 0.82 and Attainment 8 at 76. 97.4% of pupils achieved grade 5 or above in English and maths in the latest stored GCSE figures. In the sixth form, 27.2% of entries were awarded AAB or better at A level. Destinations data also suggest strong progression after sixth form, with 75% moving into higher education.
Published school information highlights facilities such as Library. The wider offer currently includes Debate club, Drama, Duke of Edinburgh. 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. Chislehurst and Sidcup Grammar School is likely to appeal most to families who want strong academic expectations but also need the practical details, culture, and selective route to line up sensibly.
