Admissions and the 11+
- Admissions policy
- Selective (grammar school)
- Selection in this area
- Fully selective area27% of Year 7 places offered in Bexley for September 2026 were at selective schools (DfE applications and offers). We class an area as fully selective at 25% or more. Confirm with the local authority's admissions guide.
- Entrance test
- Not yet available
- Qualifying score
- Not yet available
- Catchment area
- No catchment area. Bexley council says there are no catchment areas in Bexley, although distance from home to school is used to decide some places.
- Children from outside the catchment
- Yes: Children who pass the Bexley selection test can apply from anywhere. Children with one of the highest 180 scores in the Bexley test get priority wherever they live; most remaining places then go by straight-line distance from home to school (after siblings and other priority groups), so children living far away are unlikely to get a distance place. (Arrangements as described for 2023 entry; check the school's current arrangements.)

"Applicants" counts every family that listed the school as any preference, so it is higher than the number competing for each place. "Outside Bexley" means a home in another local authority; it is not the school's catchment area. For grammar schools, offers also depend on the entrance test result.
