School applications
We've matched the postcode to Essex.
You apply through this education local authority even if the school is in another council area.

Last published allocation
None of the schools listed here has a published last-distance figure, so we cannot compare a postcode with last year's allocation. We do not draw catchment maps in this list; where we hold a council's map, it is on the school's page.
