Passing the 11+ qualifies a child for consideration at a grammar school — it does not, on its own, guarantee a place. If a school gets more qualified applications than spaces, it ranks those qualifying children using its own published oversubscription criteria: typically a priority order covering looked-after children, siblings, distance and, sometimes, the test score itself.
Qualifying is not the same as being offered a place
This is the single most important — and most misunderstood — fact about grammar school admissions. The 11+ sets a qualifying standard: a mark or band a child must reach to be eligible for a grammar place at all. It is not, by itself, a ranking of every child who reaches that standard. In a popular grammar school's catchment, especially in a heavily selective area such as Kent (which has 36 grammar schools alone) or Buckinghamshire, the number of children who qualify each year can comfortably exceed the number of places on offer. When that happens, the school does not simply take the highest scorers until the places run out by default — it applies its own published oversubscription criteria to decide, in a fixed priority order, who is actually offered a place.
The mechanics of oversubscription criteria generally — including the statutory requirement that looked-after and previously looked-after children come first — are already covered for state schools broadly in our guide to what admissions oversubscription criteria are. This article focuses on the specific twist that applies to grammar schools: what happens once a child has already cleared the academic bar, and how "qualified but not offered a place" can still happen.
A typical grammar school priority order
Every grammar school's admissions policy is legally required to set out its own oversubscription criteria in a fixed, published order — schools cannot make up the order case by case, and the criteria must be objective and measurable. While the exact order and detail vary from school to school, a commonly seen pattern among grammar schools looks like this:
| Priority | Criterion | What it typically means |
|---|---|---|
| 1 | Looked-after and previously looked-after children | Children in local authority care, or who left care via adoption, a Special Guardianship Order, or a Child Arrangements Order — this must come first by law |
| 2 | Children with an Education, Health and Care Plan naming the school | Where the school is specifically named in a statutory EHC plan |
| 3 | Siblings already attending the school | Usually defined as a brother or sister who will still be enrolled at the school in the September the applicant would start |
| 4 | Distance or catchment area | Measured by straight-line distance or a defined catchment boundary, depending on the school |
| 5 | Faith criteria (faith-designated grammar schools only) | Evidence of religious practice, verified via a supplementary form |
| 6 | The 11+ score itself, as a ranking or tie-break factor | Used either to rank remaining qualified applicants directly, or to break ties within a distance or catchment band |
Why the test score can appear twice
It is worth being explicit about something families often find confusing: the 11+ score does two separate jobs. First, it sets the qualifying bar — a child either reaches the required standard or does not. Second, at some (not all) grammar schools, the score is used again, further down the priority order, either to rank oversubscribed qualifiers directly or as the tie-breaker when two applicants are otherwise equal on every criterion above it — for example, two sibling applicants living the same distance from the school. Whether a school uses the score this way at all, and exactly how, is set out in that school's own admissions policy — it is not a universal rule.
How the sibling rule works in practice
A sibling criterion typically requires the older child to be enrolled at, and still attending, the grammar school in the September the younger child would join — a sibling who has already left the school (for example, into sixth form elsewhere) usually does not count. Definitions of "sibling" vary between schools and can include half-siblings, step-siblings and children living permanently at the same address, so it is worth reading the exact wording in the specific school's policy rather than assuming a family's situation automatically qualifies.
Why this is always school-specific
Every grammar school publishes its own admissions policy, and the exact order, wording and detail of its oversubscription criteria can differ from the school down the road — even within the same local authority. The pattern above is genuinely common, but it is illustrative, not universal: some grammar schools weight catchment ahead of siblings, some do not use faith criteria at all, and some do not use the test score as a ranking factor beyond the initial qualifying bar. The only way to know exactly how a specific grammar school will treat your child's application is to read that school's current, published admissions policy in full — usually available on the school's own website or via the local authority — well before the application window opens.

FAQ
If my child passes the 11+, are they guaranteed a grammar school place?
No. Passing the 11+ means a child has reached the qualifying standard, which makes them eligible for consideration — it does not guarantee a place if the school is oversubscribed among qualifying applicants. In that case, the school ranks qualified applicants using its own published oversubscription criteria.
Does living in the catchment area guarantee a grammar school place?
No. Catchment area is usually just one of several oversubscription criteria, applied after higher-priority factors such as looked-after children and, at many schools, siblings. If the number of qualifying applicants within the catchment exceeds the number of places, the school will use the next criterion in its priority order — often distance — to decide between them.
Is the priority order the same at every grammar school?
No. Every grammar school publishes its own admissions policy, and while common patterns exist — looked-after children first, then often siblings and distance or catchment — the exact order, definitions and use of the test score as a tie-break all vary by school. Always check the specific school's current published policy rather than assuming a general pattern applies.
Does a sibling already at the grammar school guarantee a place for a younger child?
Not automatically. A sibling relationship is usually a genuine advantage, since it is typically ranked ahead of distance or catchment criteria, but it does not override higher-priority criteria such as looked-after status, and it will not help if the sibling has already left the school by the time the younger child would start. Read the school's own definition of "sibling" carefully, as eligibility rules vary.
