School applications

We've matched the postcode to Hertfordshire.

You apply through this education local authority even if the school is in another council area.

East Hertfordshire is the district council. School applications go through Hertfordshire.

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.
