What percentage of children pass the 11 plus nationally?

There's no single official 'pass rate' published for the 11+, because it isn't a pass/fail exam in the way GCSEs are — but the wider context is telling. According to the House of Commons Library, there are 163 grammar schools in England with around 176,000 pupils, representing only about 5.3% of all state-funded secondary pupils. That's the national backdrop: grammar places are a small slice of the total, which is the main reason the 11+ is so competitive almost everywhere it's used.

Is the 11 plus pass rate the same everywhere?

No — this varies enormously by area, far more than most national figures suggest. The Department for Education officially classifies 'highly selective' areas as those where 25% or more of state secondary places are in grammar schools — places like Kent and Buckinghamshire. In these areas, a much larger share of children who sit the test go on to get a place. In areas with only one or two grammar schools serving a large, densely populated catchment — parts of outer London are the most cited example — the ratio of applicants to places can be dramatically steeper.

How many children sit the 11 plus each year?

Estimates commonly cited by tutoring organisations put the figure at roughly 100,000 children sitting the 11+ across England each year, spread across around 35 local authorities that still operate selective admissions. This figure isn't an official government statistic in the way the House of Commons Library's grammar school numbers are, so treat it as a reasonable estimate rather than a precise count — but it gives a useful sense of scale relative to the roughly 176,000 total grammar school population across all five year groups.

Does 80% mean 80% of children pass?

No — and this is a genuinely common mix-up worth clearing up. Some sources describe an 'average pass mark of around 80%', but that's a comment on the raw percentage score some children achieve on the actual paper, not the proportion of children who pass or qualify. These are two completely different numbers. The proportion of children who actually go on to secure a grammar school place is a much smaller figure, and it's driven far more by how many grammar places exist locally than by any fixed percentage score.

Why does the 11 plus feel so much harder in some areas than others?

Because the ratio of applicants to available places is the real driver of difficulty — not the exam content itself, which is broadly similar everywhere a given exam board is used. An area with many grammar schools relative to its population (like Kent, with around 32) offers proportionally more places than an area with very few grammar schools serving a much larger population. This is also why 'super-selective' schools — a small number of grammar schools that draw applicants from an unusually wide area — can see many times more applicants per place than a typical local grammar school.

Does a lower local pass rate mean the exam is harder?

Not necessarily in terms of content — most children sitting GL Assessment in one area are facing broadly the same style of question as those in another GL Assessment area. What differs is the level of standardised score needed to actually secure a place, because that's set by supply and demand locally, not by the difficulty of the paper. A child who would comfortably qualify in a highly selective area might narrowly miss out in a more competitive one, despite putting in the same score.

What Percentage of Children Pass the 11 Plus?

The National Picture

There's no single official "pass rate" for the 11+, because it isn't a pass/fail exam in the way GCSEs are — a standardised score qualifies a child for consideration, but what actually happens next depends entirely on how many grammar places exist where you live. That said, the wider context explains a lot about why it feels so competitive almost everywhere.

According to the House of Commons Library — the UK Parliament's own research service, and the most authoritative published source on this — there are 163 grammar schools in England, with a total of around 176,000 pupils across all five year groups. That works out to roughly 5.3% of all state-funded secondary pupils nationally. Put simply: fewer than 1 in 20 secondary school places in England are grammar school places. That scarcity, not the exam content itself, is the single biggest reason the 11+ is so hard to "pass" in the everyday sense parents mean.

Key Takeaways

Only ~5.3% of English state secondary pupils attend a grammar school — official House of Commons Library data.
There's no single national "pass rate" — it depends entirely on local supply of grammar places versus demand.
"80% pass mark" and "pass rate" are different things — a raw score percentage isn't the same as the proportion of children who get a place.
"Highly selective areas" (officially, 25%+ of local secondary places are selective) have meaningfully better odds than areas with few grammar schools.
Super-selective schools that draw from a wide catchment can see far steeper competition than a typical local grammar.

Two Different Numbers, Often Confused

Search around for "11 plus pass rate" and you'll quickly run into a genuinely common mix-up, repeated across a lot of otherwise well-meaning advice: conflating the pass mark (a percentage score on the paper) with the pass rate (the proportion of children who actually secure a place). These are completely different statistics.

Pass mark: a raw or standardised score threshold — for example, "you typically need around 80% of marks" or "a standardised score of 121+."
Pass rate: the proportion of children who sit the test and go on to get a grammar school place — a figure driven almost entirely by local supply and demand, not by how the paper is marked.

A region can have a demanding pass mark and a relatively generous pass rate (many grammar places, so more children who clear the threshold get in), or the reverse — a moderate pass mark but a brutal pass rate, because vastly more children apply than there are places. Knowing which number you're actually looking at matters far more than the number itself.

Why It Varies So Much by Area

The Department for Education officially defines "highly selective" areas as those where 25% or more of state-funded secondary places are in selective schools — Kent and Buckinghamshire are the most commonly cited examples, each with dozens of grammar schools serving their local population. In these areas, a meaningfully larger share of children who sit the 11+ go on to secure a place, simply because there's more grammar capacity relative to demand.

Contrast that with areas that have only one or two grammar schools serving a large, densely populated catchment — parts of outer London are the example raised most often in parent discussions. Here, the same standardised score that would comfortably secure a place in a highly selective area can fall well short, purely because so many more children are competing for so many fewer places.

The takeaway: "How likely is my child to pass?" doesn't have one national answer. It depends far more on how many grammar schools serve your specific area than on anything else — check our school database or your regional guide to understand your local landscape before benchmarking against a national figure.

Super-Selective Schools

Within any region, a small number of "super-selective" grammar schools draw applicants from an unusually wide catchment — sometimes an entire county or beyond — rather than a typical local intake area. Because so many more families apply to these specific schools relative to their (often smaller) number of places, competition runs considerably steeper than at a standard local grammar school, even within an otherwise "highly selective" area. A standardised score that would be comfortably above the norm at most schools may still fall short at a genuinely super-selective one, where places are typically allocated strictly to the highest scorers rather than against a fixed threshold.

What This Actually Means for Your Child

Three practical conclusions follow from all of this:

Research your specific local landscape, not a national average. The number of grammar schools relative to your area's population matters more than any headline figure.
Treat the published qualifying score as a floor, not a target — especially in competitive areas, where places often go strictly by rank rather than a fixed pass/fail line. See our guide to what the pass mark actually means for the full breakdown.
Consider more than one target school where realistic, particularly if your local area is on the more competitive end — this is standard practice for many families, not a sign of low expectations.

Whatever your local landscape looks like, the preparation fundamentals are the same: strong core skills, genuine familiarity with Verbal and Non-Verbal Reasoning, and realistic timed practice.
