Chislehurst and Sidcup Grammar School is a co-educational selective grammar in Sidcup, serving ages 11 to 18. The school describes its purpose in outward-looking terms: to educate inquiring, well-informed and compassionate young people who can take responsibility and influence the world around them. That purpose is matched by practical expectations around high academic standards, creativity, leadership, healthy lifestyles, self-discipline and respectful relationships.
Academically, CSGS presents itself through an 'Academic Excellence' area covering curriculum, subject information, homework and careers education, with a substantial sixth form as part of the same school community. The sixth-form pages highlight a study programme, university guidance and student destinations, while the main values page makes clear that the complementary curriculum matters alongside examination success. This is a large school, with around 1,517 pupils, so the sixth form and the co-educational character both shape the daily feel of the site.
The school-life menu is unusually useful for understanding the offer. CSGS signposts clubs and societies, creative and performing arts, sport, educational trips, personal development, Quest Lectures, student leadership, the Marlborough School partnership, Duke of Edinburgh and school traditions. The library is a named part of the pupil experience, and the co-curricular evidence also includes debate, drama and sport as visible co-curricular routes. The result is a grammar school that presents intellectual life and participation as connected rather than separate strands.
Year 7 has 192 places and uses the Bexley selection system.
