How Grammar Schools Decide Between Children With the Same 11+ Score

Two girls tie on the 180th mark at The Tiffin Girls' School and the place goes to an independently verified draw. Two boys tie at Watford Grammar School for Boys and the lower door number wins. At Queen Elizabeth's School, Barnet, 225 is the qualifying mark and distance separates only what the marks could not. Five schools, five published rules — and this page quotes all five.

Does the law require a tie-break at all?

Two children sit the same paper on the same morning and finish on the same standardised mark. One is offered a place and the other is not. Most parents assume a decision is made at that moment — that somebody in an admissions office weighs up two applications and picks. That is not what happens. The rule that separates those two children was written, consulted on and legally determined months before either of them picked up a pencil, and in every case we checked it is published on the school's own website, in a document any parent can download.

The School Admissions Code is explicit that having such a rule is not optional. It requires that "Admission arrangements must include an effective, clear, and fair tie-breaker to decide between two applications that cannot otherwise be separated." Three words in that sentence do a lot of work. Effective means the rule has to actually resolve the tie rather than restate it. Clear means a parent should be able to read it and predict the outcome. Fair means it cannot become a back door to something the school is not permitted to select on.

The Code also closes the most obvious loophole. "Admission authorities must not adjust the score achieved by any child in a test to take account of oversubscription criteria, such as having a sibling at the school." A sibling already on roll, a parent on the staff, an application submitted early — none of these can be converted into marks. They may exist elsewhere in the criteria as a separate category, but the score itself is untouchable. If your child is tied, they are tied on a number nobody is allowed to nudge in either direction.

Where a tie does end in a draw, two conditions apply that most families have never been told about. The Code states that "The random allocation process must be supervised by someone independent of the school, and a fresh round of random allocation must be used each time a child is to be offered a place from a waiting list." The second half of that sentence is the half that matters in June. A ballot is not run once in March and then read down like a queue. Every single waiting-list offer triggers a new draw among whoever is tied at that point.

A lottery also cannot be allowed to become the system. The Code says local authorities "must not use random allocation as the principal oversubscription criterion for allocating places at all the schools in the area for which they are the admission authority." Randomness is a separator of last resort, not a method of allocation. The Code's own model arrangements show the intended shape plainly: "Random allocation will be used as a tie-break in category '3' above to decide who has highest priority for admission if the distance between two children's homes and the school is the same. This process will be independently verified."

That two-stage shape — a separator, then a draw for whoever the separator cannot separate — is the spine of everything below. What varies, and varies far more than the general advice on this subject admits, is what the separator is. Families working towards grammar school entrance almost always assume it is distance. In two of the five sets of determined arrangements we read in full for this page, distance is not the first thing that happens.

Where is the distance to the school actually measured from?

Nearly every article on this subject contains the same sentence: distance is measured in a straight line, as the crow flies. That is true, and on its own it is not enough to be useful. A straight line has to start somewhere and end somewhere, and the two schools in this group that publish their measurement method in detail do not end it in the same place.

The Tiffin Girls' School sets it out like this: "The starting point of the measurement is a grid reference point for the property, which is supplied by Ordnance Survey. The end point is measured to the nearest school gate." The nearest gate. Not the front door, not the reception, not the postcode centroid — whichever of the school's gates happens to be closest to your home. On a large urban site with entrances on more than one road, that choice can move the endpoint by a meaningful distance, and it moves it differently for families approaching from different directions.

Queen Elizabeth's School, Barnet publishes a different endpoint. Its rule reads: "In the event of two or more applicants scoring the same mark, the rank order for allocation of places will be determined by the distance measured in a straight line between the address point for the child's home, supplied by Ordnance Survey, and the main School gate, with the closest given the highest rank." The main gate, singular and fixed. Both schools start from an Ordnance Survey address point, so the home end is identical in method; the school end is not.

This is not a pedantic distinction. Where a tie-break comes down to metres — and it does, because the whole point of a tie-break is that everything else has already failed to separate two children — the difference between the nearest gate and the main gate is the difference between an offer and a waiting list. Neither school is doing anything unusual. They simply made different drafting choices, and a parent comparing the two schools by measuring to the same point on a map is comparing the wrong thing.

It is also worth noting what the distance is not doing. It is not a catchment in either case. It is the rule applied after the marks have already been ranked, to separate children the marks could not. Families used to comprehensive admissions, or to the distance-heavy criteria that govern other selective entry points, often carry over the assumption that living close is the primary asset. At the schools below it is a secondary one, and at one of them it does nothing at all until two boys finish on exactly the same mark.

What do five published tie-breaks actually say?

These are the five sets of determined arrangements we read in full. They were chosen because all five are academically selective and heavily oversubscribed, which makes ties routine rather than theoretical, and because all five publish their arrangements as documents rather than summaries. What the five together demonstrate is that there is no such thing as "the" grammar school tie-break.

Queen Elizabeth's School, Barnet is the cleanest case in the group, because the school removes every other variable: "Queen Elizabeth's School has no catchment." Nothing about where a boy lives affects whether he is considered, only the order in which identically scoring boys are ranked. The school is equally blunt about the other factors families ask about. Asked whether it gives priority to pupil premium candidates, its published answer is "No. Admission is based solely on entrance test results." There is no sibling rule and no aptitude rule to discuss. The tie-break is the only non-score element in the entire policy.

The Henrietta Barnett School works the opposite way round. It has a distance criterion, covering candidates living within three miles of the school at the point when they submit their application, and that criterion sits above open rank order. Rank by score is applied inside a category, not across the whole cohort: "In the unlikely event that there are more candidates in this category than places available, then places will be allocated in rank score order." A description of the school as ranking purely on marks, which is how most guides describe it, is simply not what the policy says.

The Tiffin Girls' School runs a three-step tie-break in which distance comes last. Looked-after status is first, pupil premium second, proximity third. The pupil premium step reads: "To the girl whose school is currently in receipt of pupil premium funding for her. Evidence will be required (see paragraph 2.10.6). If there is more than one girl in this category, the girl who lives nearest the School (see paragraph 5.2.4) will be offered a place first." Distance is the separator inside the category, not the separator between categories.

The Latymer School inverts the expected order more sharply than any other school here. Its clause on a tie for the final place reads: "preference will first be given to students who are on pupil premium (ranked within the top 900) but haven't been offered a place under this category, then to students who show musical ability (ranked within the top 700) but haven't been offered a place under this category and then those who live closest to the school using local authority measurement calculations." Two children on identical marks, living identical distances away, can be separated by a musical aptitude ranking.

Read the table as a warning against generic advice. Four different first separators appear in five schools. A family whose shortlist crosses two of these admission authorities is preparing for two different competitions, and the thing that decides a close case at one school is not even mentioned in the arrangements of the next.

How often does it really come down to a draw?

The common claim, which this page used to make itself, is that a ballot is a theoretical curiosity, because distance measurement is precise enough to separate almost anyone. That claim does not survive contact with the documents. Four of the five schools we read publish an explicit random-allocation clause, and two of them publish a clause written specifically for children whose measured distance is identical. Schools do not draft rules for events that never occur.

The Henrietta Barnett School names the scenario directly: "Applicants from the same block of flats, or applicants who live the same distance from the school will be selected in random order using London Borough of Barnet's computerised system and places will be offered accordingly." Note what the clause takes for granted. A block of flats has one address point, so every child in the building is exactly the same distance from the school. In dense parts of north London that is not an edge case, it is Tuesday.

Watford Grammar School for Boys handles the same problem without any randomness at all, and publishes what is probably the most granular tie-break in English selective admissions: "In the event of two boys living an equal distance from the school (e.g. in a block of flats) the boys will be ranked numerically by house/door number, the lower number taking priority. If the boys live at equal distance but in different locations, the place will be allocated by independently verified random allocation." Flat 3 beats Flat 7. It is arbitrary, but it is published, deterministic and knowable in advance, which is exactly what the Code's requirement for a clear tie-breaker asks for.

Where a draw does run, the supervision requirement is real rather than notional, and one school spells out the mechanics in the part of its policy dealing with sixth form entry: "Where two or more applicants ranked equally in the test live equidistant from the School, places will be allocated by random allocation (this process will be supervised by somebody independent of the School)." The Tiffin Girls' School uses the same construction at its final place: "If more than one girl is on the 180th score and all live the same distance from the School, the place will be allocated by random selection and this process will be independently verified."

So the honest position is the reverse of the usual one. Ties are common enough that every school in this group has a written procedure for them; draws are the fallback rather than the norm, but they are a live fallback with named supervision and a verification step. What is genuinely rare is a family being told, after the event, which limb of the tie-break decided their child's application. The rules are public. The specific outcome usually is not.

Why does one school run a tie-break at the 60th place?

Almost everything written about tie-breaks assumes the tie happens at the last place in the intake. That is where the pressure is most visible, and it is where the phrase "cut-off score" comes from. But there is no rule that says a tie-break can only run at the end, and The Tiffin Girls' School publishes one that runs in the middle of its allocation.

The clause reads: "In the event of there being more than 60 girls who are eligible under paragraph 5.1.2.2 and there is a tied-score to fill the 60th place, the place will be offered to the girl who lives nearest to the School (as measured in paragraph 5.2.4). If more than one girl is on the 60th score and all live the same distance from the school as measured in paragraph 5.2.4, the place will be allocated by random selection and this process will be independently verified." A block of places is capped, so the boundary of that block is its own contest, with its own separator and its own draw.

The same school also publishes a rule that changes who is in the tied group in the first place. For looked-after and pupil premium girls in its Designated Area, it applies a leeway to the marks: "At Stage Two, the School will calculate 10% of the 350th ranked mark. This will be the leeway. This will be subtracted from the 350th ranked mark, and any girl who falls within the range of the 10% leeway and who is eligible under paragraph 2.10.2 will be prioritised under paragraphs 5.1.2.2 and 5.1.2.3." The leeway is not a bonus added to a girl's own score, which the Code forbids; it is a threshold calculated once from the cohort and used to decide eligibility for a category.

Layered on top of that is geography, and here the school is unusually candid about the practical effect. "Since the Designated Area was introduced in September 2014 all places have been offered to children living inside it. The Designated Area is made up of 44 postal districts and these are set out in the admissions policy." That single sentence should end any conversation about the school being a pure rank-by-score institution. A girl outside those 44 districts is not competing on the same terms as a girl inside them, whatever her mark.

The practical consequence for a family is that "the cut-off score" is not one number. At this school it is at least two, sitting at two different points in the list, each with its own tie-break, and both sitting inside a geographic frame that has decided every offer for over a decade. Any preparation plan built around a single remembered figure from a forum is planning for a competition that does not exist.

Can the same score win in one postcode and lose in another?

Yes, demonstrably, and one school publishes the figures that prove it. Watford Grammar School for Boys divides its specialist places between two geographic zones, so a boy is not competing against the whole cohort but against the boys in his own area. The arrangements state: "Watford area: The school will reserve 47 specialist places (60% of the total specialist places) for boys whose normal home address lies within the Watford area. Of these places, 13 are reserved for musical aptitude and 34 are reserved for academic ability." The remaining specialist places are held for the rest of the admission area, which the school calls the Traditional area.

There is no threshold to clear. The school is explicit: "No minimum score will be required to gain admission, with places being offered strictly in descending order of candidates' standardised test scores." That makes the outcome purely a matter of rank — and because the ranking runs separately in each zone, the mark required to secure a place is a different number in each zone. The school publishes those numbers on allocation day.

Read the top row slowly, because it is the single most concrete answer to the question this page is about. In the same intake, at the same school, sitting the same test on the same day, the lowest academic score offered was 200 in one area and 214 in the other. That is a gap of 14 standardised points — 214 minus 200 — created by nothing except which side of an administrative boundary a boy's home sits on. A boy on 205 in the Watford area is in. A boy on 205 in the Traditional area, with exactly the same paper and exactly the same marks, is not.

The gap is not a one-year artefact either, though it does move. In the two earlier years published in the same table, the Watford area figures were 203 and 203 while the Traditional area figures were 213 and 216, so the direction of the gap held even as its size changed. The music places tell the same story in miniature, with the lowest music test score offered in the Watford area recorded as 33, 35 and 36 across the three published years.

The scale of competition behind those numbers is published too: "There were a total of 974 applicants who named us as a preferred school to their Local Authority, of which 705 of these sent us a School Information Form." That is 705 of the 974, or 72.4%, completing the school's own supplementary step. Nothing in that data says the test got harder. It says a boy's score is only meaningful once you know which queue it was placed in.

Do ties stop mattering after National Offer Day?

Most coverage of this subject stops on the first day of March, as though the ranking is dissolved once offers go out. It is not. The same tie-break machinery is what orders the waiting list, and it keeps running for months.

The Tiffin Girls' School states it directly: "The waiting list will be held in the order of paragraph 5.1.3 of the Selection Criteria and will automatically consist of the names of children who did not receive a higher preference offer. If there are several girls on the same score, then they will be placed in rank order of paragraph 5.2." Paragraph 5.2 is the tie-break itself — looked-after status, pupil premium, then nearest. A list ordered by those rules is not fixed. A family moving into the area, or a new application arriving in May, is inserted at its correct rank, which means a tied child can move down a list without anybody doing anything wrong.

Layer on the Code's condition that "a fresh round of random allocation must be used each time a child is to be offered a place from a waiting list" and the picture changes again. Where a group of children is tied all the way through the tie-break, they are not permanently ordered by a single March draw. Each offer is a new draw among the tied group. Losing one is not the same as being behind for the year, which is the single most useful thing a family sitting on a list in June can know.

The depth those lists reach is published by three of these schools, and the numbers are less bleak than most parents expect. The Latymer School describes its process as ranking "all applicants and offer places to the top 192, in line with the school's admissions criteria, placing the next 50 highest-ranked applicants on a waiting list." The Henrietta Barnett School reported that "Second round offers were made on Thursday 26th March. As of 18th August we have offered up to number 40 on the waiting list." Queen Elizabeth's School, Barnet publishes the equivalent: "The waiting list for entry into Year 7 in September 2026 has reached position 20."

Those are real, published movements, not encouragement. A child ranked in the low twenties at Queen Elizabeth's or in the thirties at Henrietta Barnett was inside the range that received offers in the intake those figures describe. Nobody can promise the same depth in another year, and the schools do not. But a waiting-list position is a live number attached to a live process, and the process is the same tie-break that decided the original offer.

Which schools does this page cover, and which does it not?

This page is built from five sets of determined arrangements, all of them in London and Hertfordshire: Queen Elizabeth's School Barnet, The Henrietta Barnett School, The Tiffin Girls' School, The Latymer School and Watford Grammar School for Boys. Everything quoted above comes from those documents or from the schools' own admissions pages. Where a document did not answer a question, the table says so rather than filling the gap with something plausible.

It follows that this page does not describe the systems in Kent, Buckinghamshire, Sutton, Birmingham or Lincolnshire, all of which have their own consortium arrangements and their own tie-breaks. Nor does it describe Tiffin School, the boys' school, which is a separate admission authority from The Tiffin Girls' School. It was not among the documents we read, so this page makes no claim about it — and that distinction matters, because the two schools are routinely conflated in advice written about ties.

One further limitation is worth stating plainly. Queen Elizabeth's School, Barnet publishes its full admissions criteria in a viewer that could not be read programmatically, so the quotations from that school come from its own public entrance test FAQs and admissions process pages rather than from the determined arrangements document. Those pages are primary and they are the school's own words, but a family relying on a fine distinction should open the formal document as well.

The general point behind all of this: a tie-break is a local rule, not a national one. The Code sets the frame — there must be one, it must be clear, a score may not be adjusted, a draw must be supervised. Everything inside that frame is the individual school's drafting. The only reliable way to know how a close case is decided at the school your child is sitting for is to open that school's arrangements and read the clause.

What do these rules mean for how a child should prepare?

The instinct after reading all of this is to ask for a target number, and the honest answer is that the target is a different kind of thing at each school. At Watford Grammar School for Boys, with no minimum score and places offered strictly in descending order within a zone, the target is a rank rather than a mark, and the rank is contested only against boys in the same area. At Queen Elizabeth's School, Barnet, there is a stated threshold: candidates "achieving a combined score of 225 or higher will be deemed to have met the standard required by the Governors to be eligible to be considered for admission to the school". Meeting it is entry to the competition, not the end of it.

At The Latymer School the target is a position inside a ranked cohort, and the school is unusually frank about how crowded that position is: "Please note that due to several applicants sharing the same ranking position, it is likely that there will be more than 700 applicants in the top cohort." A cohort described as the top 700 routinely contains more than 700 children, because ties are not exceptional there. If your child is aiming at that band, the tie-break is not a remote contingency; it is a normal part of how the school gets to a list.

At The Henrietta Barnett School, where "The Published Admission Number (PAN) for September 2027 entry is 120", the structure rewards a different kind of preparation again, because the first stage does not eliminate ties — it carries them forward. "If there is a tie at the cut-off score, then all those with the tied score will be invited to sit the Round Two test." A child on the boundary of the first test is not fighting for the benefit of the doubt; the arrangements grant it. What that child needs is to be ready for a second, different paper.

So the useful preparation question is not "how many marks are enough". It is "which competition is my child actually in, and what separates children who finish level in it". That question has a different answer for a boy in the Traditional area at Watford than for a girl inside a Designated Area postal district, and neither answer transfers to the other school. Working through the arrangements for a specific shortlist takes an evening and changes what a year of subject work should be aimed at.

It also changes what is worth worrying about. A family cannot move a door number, cannot acquire a musical aptitude ranking in March, and cannot influence a supervised draw. What is inside a family's control is the mark, and the mark is the one input the Code guarantees nobody may adjust for any other reason. Everything else on this page is context for why a strong mark, at the right school, in the right zone, is the only lever there is.
