Wilmington Grammar School for Girls

GCSE results are well above national averages, but the same cohort's A-level outcomes were officially rated 'below average' by DfE's own value-added measure — a real, statistically significant contrast worth knowing before choosing a sixth form.

Wilmington Girls admits by the standard Kent Test pass, then a narrow 'Governor Places' category (up to 18 places, for exceptional Maths-paper performance within 5 miles) sits alongside — but doesn't replace — the ordinary priority-then-distance system, so the school isn't superselective in the way some Kent grammars are. The most important thing for families to know: while GCSE results are consistently strong and well above local and national averages, the same leaving cohort's A-level outcomes were rated 'below average' on DfE's own statistically significant value-added measure for three consecutive years — a genuine and surprising gap between the two stages worth checking before assuming continuity.

GL Assessment is widely reported but wasn't named on any KCC page found during this research.

Test format
The standard county-wide format: an English & Maths paper and a Reasoning paper (verbal and non-verbal), both multiple-choice/computer-marked, plus an unmarked writing task for borderline decisions.
Qualifying / pass mark
Confirmed directly from Kent County Council's own page (2025 cycle, governing September 2026 entry): an aggregate of 332 or more, with no single component below 108. The school sets no additional threshold of its own for standard entry.
Superselective?
No

The school's own determined admissions policy allocates places to girls assessed suitable for grammar school through the standard Kent procedure, then resolves oversubscription through priority category and distance — no higher aggregate score or banding requirement exists for the main intake. The one selective sub-category, 'Governor Places' (up to 10% of places, for exceptional performance in the Kent Test Maths paper within 5 miles), is a narrow supplementary category layered on top of standard entry, not a banding of the whole cohort.

Catchment & priority criteria

A defined priority area exists: a 1.5-mile inner radius plus a long list of named parishes and wards across Dartford, Sevenoaks and Swanley districts, with Pupil Premium children prioritised within it; a further 3-mile radius applies to other Pupil Premium children; and a separate 5-mile radius applies specifically to the Governor Places category.

  1. Children with an EHCP naming the school
  2. Looked-after and previously looked-after children
  3. Siblings at this school or at Wilmington Grammar School for Boys
  4. Children of staff (2+ years' service, or filling a skill-shortage post)
  5. Governor Places — exceptional Maths-paper performance within 5 miles (up to 18 places)
  6. Girls within 1.5 miles or within the named priority-area parishes/wards, with Pupil Premium children prioritised within this group
  7. Other Pupil Premium children within a 3-mile radius
  8. All other eligible girls, ranked by straight-line distance

DfE's A-level progress (value-added) score was -0.39, banded 'below average' with a confidence interval (-0.5 to -0.28) entirely below zero — a statistically significant result, not noise, and a real contrast against this same cohort's strong GCSE outcomes.
