Chislehurst and Sidcup Grammar School
About Chislehurst and Sidcup Grammar School
Chislehurst and Sidcup Grammar School is a heavily oversubscribed state secondary in Bexley, with 1,327 applications for just 192 places in the 2025/26 admissions round — an oversubscription ratio of nearly 7 to 1. The school currently holds 1,517 pupils against a capacity of 1,344, meaning it is running well above its official number. That level of demand makes sense when you look at the intake profile: just 2.7% of pupils are eligible for free school meals, compared with a national average that typically sits around 20-25% in secondary schools. This is a selective grammar school drawing from a wide area, and the first-preference figures tell a similar story — 272 families put it as their top choice, with 145 receiving offers. For parents considering whether their child will fit in, the data suggests a largely middle-class, academically driven cohort where competition for a place is fierce from the outset.
