Mayfield Grammar School, Gravesend

Ranks applicants by geography first and test score only as a tiebreaker within each zone — the opposite of how a superselective school allocates places.

Mayfield was literally called 'Gravesend Grammar School for Girls' until a 2011 rename — the two schools share a town and a history but are now fully independent, with no shared governance. Mayfield offers an optional second-chance route, 'The Mayfield Procedure', set by CEM at Durham University, distinct from the Kent Test's usual provider. Its own admissions policy confirms it isn't superselective in the usual sense: applicants are ranked by geographic priority zone first, with the Kent Test score used only as a tiebreaker within each zone — the reverse of how a genuinely superselective school would allocate places by score first.

Admissions

Admissions authority
The school sets its own test and criteria
Entrance test board
Primary route: the Kent Test, commissioned by Kent County Council (GL Assessment reported as paper-setter, not confirmed by KCC directly). Optional secondary route: 'The Mayfield Procedure', the school's own supplementary assessment with a computer-based component set by CEM (Centre for Evaluation and Monitoring, Durham University) — directly confirmed in the school's own admissions documents.partly verified

GL Assessment for the Kent Test is widely reported but wasn't found named on any KCC page checked during this research.

Test format
Kent Test: an English & Maths paper, a Reasoning paper (verbal and non-verbal), and an unmarked 40-minute writing task for borderline decisions. Mayfield Procedure (optional, for girls seeking a second opportunity): a locally-standardised computer test weighted 50% verbal / 25% Maths / 25% non-verbal reasoning, plus a separately marked English writing paper.
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. Mayfield's current admissions policy governs September 2027 entry, whose threshold Kent County Council won't publish until October 2026 — not yet knowable at the time of writing, not a research gap. The school sets no additional threshold of its own.
Superselective?
No

Confirmed directly from the school's own determined admissions policy: eligibility requires only the standard county-wide Kent Test pass. Crucially, when oversubscribed, places are allocated by geographic priority zone first (two tiers of named postcodes), with 'highest aggregated Kent Test score' used only as a secondary tie-break within each zone, ahead of proximity — the opposite mechanism from a genuinely superselective school, which would rank the whole applicant pool by score first.

Catchment & priority criteria

A two-tier geographic priority system: Priority Area 1 covers postcode prefixes across Dartford, Gravesham and parts of Sevenoaks and Swanley districts; Priority Area 2 covers a further ring. Girls outside both areas remain eligible but rank last, by score then proximity.

  1. Children with a Statement of SEN or EHCP naming the school
  2. Looked-after and previously looked-after children
  3. A sibling attending at the time of entry
  4. Girls resident in Priority Area 1 — Free School Meal recipients first, then by Kent Test score, then proximity
  5. Girls resident in Priority Area 2 — same sub-ordering
  6. All other eligible girls — ranked by Kent Test score, then proximity
  7. Random draw for the final place if applicants remain exactly equal

The A-level progress score was -0.28, banded 'below average' with a confidence interval (-0.38 to -0.19) entirely below zero — a real, statistically significant contrast against the school's own marketing description of 'almost 1 in 2 grades A*-B' for the same cohort.
