At some point in your 11+ research you'll stumble across a number that makes your stomach drop. Henrietta Barnett: roughly 3,000 applicants for around 106 places. Tiffin: about 14 applicants per place. Your first thought is probably the same one I had. What chance does my child have against odds like that?
Here's the thing. Those numbers are real, but they're also the most misleading statistics in the whole 11+ world. The headline ratio tells you almost nothing about your child's actual chances. Once you understand how the numbers are built, the picture looks very different. Sometimes better, occasionally worse, but always more useful.
What applicants per place actually measures
An application-to-place ratio is exactly what it sounds like. The school had 106 places, 3,000 children sat the test, so the ratio is about 28 to 1. Simple arithmetic, and completely true.
But it isn't a probability. It doesn't mean your child has a 1 in 28 chance, because the children sitting that test aren't a random sample. They're not even close to one.
Think about who actually registers for a school like Henrietta Barnett or Queen Elizabeth's in Barnet. These are super selective schools with no real catchment, so families travel from across London and beyond. Most have been preparing for a year or more. Many are sitting four or five other tests in the same season. The applicant pool is self-selecting, committed and well-drilled. Your child isn't competing against 3,000 random ten-year-olds. They're competing against a filtered group. In one sense that makes the contest harder than the raw ratio suggests, but it's also more honest. Everyone in the room chose to be there.
Now flip it. That same self-selection means the ratio overstates the field too. A chunk of those 3,000 applications are speculative. Parents enter their child for HBS as a long shot while focusing on a local catchment grammar. Some children sit the test with minimal preparation just to see. The number of serious, prepared candidates genuinely chasing a place is well below the headline figure.
Why the same child appears in five different ratios
Here's the bit almost nobody mentions. Application numbers count applications, not children.
A family in south-west London might enter their daughter for Tiffin Girls', the Sutton consortium test and a couple of others. That's one child inflating three or four separate school ratios. Add up the headline applicant numbers across the South East's most competitive schools. You're counting the same children over and over.
This matters because places work the other way. Each child can only accept one. So every September, children who scored well enough for three schools take up one place and release the others. Waiting lists move. The effective competition for any single place is lower than the ratio implies, because the top performers can't hoard places they won't use.
Does that mean the super selectives are secretly easy? No. A school like Tiffin still fills every seat with children scoring in the top few percent. But it does mean a near-miss isn't always final. Waiting list movement is a normal part of the system, not a rare miracle.
Super selective vs catchment grammars: two different contests
The ratio question splits sharply depending on the type of school, and this is where parents most often misread the odds.
A super selective ranks every candidate by score and takes the top however-many. No catchment, no qualifying mark you can aim for in advance. The competition is the cohort itself, so the ratio at least points at something real, even if it distorts it.
A catchment grammar works differently. In Kent, around 16,000 children sit the Kent Test each year for just over 5,000 grammar places. That sounds like 3 to 1, but it's not a rank-order contest. Kent built the test to find children working in roughly the top 25% of the year group. Reach the qualifying standard and live in the right place, and your child is in. They don't need to beat 15,999 other children. They need to clear a bar.
Buckinghamshire runs on similar logic. In recent years roughly 28% of children taking the Transfer Test have qualified automatically with a score of 121 or more. Again, that's a threshold, not a ranking. The odds for a well-prepared child in catchment are far kinder than any super selective ratio.
Then there are the hybrids. Here in Berkshire, Kendrick in Reading runs at something like ten applicants per place across its 128 spots. Most of those places go to a defined priority area first, though. Reading School works much the same way for boys. If you live in the priority area, your real competition is the other local children, not the full applicant list. If you live outside it, you're fighting for a small handful of open places and the odds get much steeper. Same school, same test, wildly different contest depending on your postcode.
So how competitive is it really for your child?
The honest answer: it depends on which question you're asking, and the ratio answers none of them.
The useful questions are these. Is your child working comfortably above the level of their year group, not just keeping up? Are you in catchment or priority area for the school you actually want, or relying on a score-only place? And is your target a threshold school or a ranking school? At a threshold school, preparation gets a capable child over a fixed bar. At a ranking school, they must outscore a strong field on the day.
A Year 5 child in Maidstone aiming for a local Kent grammar faces a completely different challenge from a child in Kingston aiming at Tiffin. Both are "doing the 11+", but the contests barely resemble each other. Treating them as the same exam with the same odds is how families end up over-prepared and burnt out, or under-prepared and blindsided.
What you can control is information. Find out the type of admissions system your target school uses before you commit to a year of preparation. Read the school's actual admissions policy, not a tutoring company's summary of it. And get a realistic, current measure of where your child sits academically. That single fact tells you more about your odds than any ratio ever will.
FAQ: 11 plus competition ratios
Is 28 applicants per place as bad as it sounds? No. That figure counts speculative entries and children applying to several schools at once. The pool of serious, prepared candidates for any single place is smaller. It's still a hard contest, but it's not a lottery with 28 tickets.
Do more children fail the 11+ than pass? In threshold regions like Kent and Buckinghamshire, yes, roughly three quarters of those who sit don't reach the qualifying standard. But remember, that's deliberate. The counties built these tests to identify around the top 25% of the year group, so the pass rate isn't a sign of impossible difficulty.
Are the odds better if we apply to more schools? Sometimes, but not automatically. Extra applications only help if your child is genuinely in contention for each school and the test dates don't clash. Adding a super selective long shot to a sensible local application costs little. Building a list entirely of long shots is how families end up with no offer at all.
Where can I find the real applicant numbers for a school? Schools publish admissions information annually, and local authorities release allocation data every March. Some schools state applicant numbers in their admissions reports. A Freedom of Information request works for the rest, though a school's published "previous years" data is usually enough to see the pattern.
Worrying about ratios is natural, but it's not preparation. The better starting point is knowing where your child actually stands right now. ReadyFor11 gives you a free, honest benchmark of your child's 11+ readiness, with no paywall and no upsell. Then you can decide what the odds really look like for your family.
