The school opened in the Autumn Term of 1931 and has been at three different sites since then. CSGS has been at the current site for over fifty years and has undergone considerable building development, including a dedicated Sixth Form study facility, Lecture Theatre, Sports Pavilion, Gymnasium, as well as specialist Drama, Music and Art & Technology blocks.
Chislehurst and Sidcup Grammar School aims to educate and prepare for life able pupils from all backgrounds. This mission is dynamically carried forward within a caring, happy and supportive community. The education that CSGS offers develops its pupils intellectually, emotionally and physically. The ingrained idea of excellence in school life allows pupils to reach the highest academic, sporting, cultural and aesthetic standards. The special quality of learning in the classroom is equally matched by the richness of teaching that pupils experience.
Whilst healthy competition is central to the CSGS ethos, there are also many opportunities for pupils to enter into the wider life of the school. Service to the school and community is enthusiastically performed and high levels of leadership and responsibility are actively taken on by pupils at all levels. There is a supreme belief that building CSGSs’ tradition of excellence comes not from dwelling on yesterday’s successes but performing tomorrow’s tasks.
The continued success of CSGS is matched by an ongoing focus on site development and improvement. Upon extremely attractive grounds, almost unique in the south east of England, a heavy investment programme in new facilities is unfolding. Aside from a range of well-resourced specialist teaching areas, the school continues to add new buildings.
