Buckinghamshire is one of the largest grammar school counties in England. Thirteen grammar schools, a single qualifying test, and a selective system that's been in place for generations. If your child is in Year 4, 5, or 6, grammar school might be on your radar. If you're looking at Aylesbury, Beaconsfield, Amersham or High Wycombe in particular, the Buckinghamshire Transfer Test matters. Here's what it is, how it works, and what you actually need to do.
What is the Buckinghamshire 11+?
Officially called the Secondary Transfer Test, it's the single assessment that determines grammar school eligibility across the county. The Buckinghamshire Admissions Team runs it on behalf of the 13 grammar schools.
Until 2019 the test was produced by CEM (Durham University). When CEM stopped making 11+ tests in 2020, Buckinghamshire moved to GL Assessment. The test now uses GL format, the same format used in Kent, Essex, and parts of Lincolnshire. If you've been collecting old CEM-style practice books, they aren't quite the right fit anymore.
Children sit the test in September of Year 6. Those who live in Buckinghamshire are registered automatically through their primary school. Out-of-county children need to register independently through the Bucks admissions site, usually by the end of June in Year 5. Miss that window and it's much harder to sort later.
What's in the test?
Two papers, each around 45 minutes, sat over two mornings. Each paper mixes verbal reasoning, non-verbal reasoning, English, and maths. The questions are multiple choice and children mark answers on separate answer sheets, which is worth practising. Some children struggle the first time they encounter the format.
English covers comprehension, vocabulary, grammar, punctuation and spelling. Maths is based on the primary curriculum up to Year 6 content. Verbal reasoning tests word relationships, codes, analogies, sequences, and logic. Non-verbal reasoning uses shapes and patterns to test spatial thinking.
What matters for practice is that GL papers move fast. Children who understand the methods but work slowly will still drop marks just on time. That's true in the reasoning sections especially, where you're often looking at roughly 30 seconds per question.
What's the pass mark?
The qualifying score is 121. That's a standardised composite score calculated across the two papers, with an age adjustment for the month the child was born in. A summer-born child doesn't have a lower pass mark. But the raw scores are age-adjusted. A child born in August isn't penalised for being nearly a year younger than a child born the previous September.
121 is the floor for all 13 grammar schools. Some of those schools are super-selective, meaning they admit by score after a distance tiebreaker. Dr Challoner's Grammar in Amersham and Dr Challoner's High in Little Chalfont both regularly fill at scores well above 121. A pass gets you eligibility. It doesn't guarantee a place at a specific school.
The review process
If your child scores below 121 but you believe they should be considered of grammar school ability, Buckinghamshire runs a review process. This isn't an appeal. It's a structured second look that happens before the secondary application deadline.
Parents submit a review form along with samples of school work and a head teacher's recommendation. A panel of headteachers and reviewers considers the whole picture. Illness on the test day, EAL status, SEN, or significant disruption around the time of the test can all be taken into account.
Is it worth pursuing a review? If your child is close to 121 and there's a credible reason they underperformed, yes. If they scored well below and the school work doesn't clearly support the case, reviews are much less likely to succeed. It's a fair process, not a rubber stamp. Bucks publishes review statistics each year and the success rate varies, but it's never high.
Which grammar schools are there?
Thirteen grammar schools, and they differ significantly by location, sex, size and character.
Aylesbury Grammar (boys) and Aylesbury High (girls) serve the Aylesbury area. Sir Henry Floyd (mixed) is also in Aylesbury. Dr Challoner's Grammar (boys) and Dr Challoner's High (girls) sit in Amersham and Little Chalfont respectively and are super-selective. Beaconsfield High (girls) and Chesham Grammar (mixed) serve the south of the county. Royal Grammar School High Wycombe (boys), John Hampden (boys), and Wycombe High (girls) are in High Wycombe. Sir William Borlase's (mixed) is in Marlow. Burnham Grammar (mixed) sits near Slough. The Royal Latin (mixed) is in Buckingham in the north.
Distance matters enormously. Most Bucks grammar schools prioritise children who live closest. Applying to Dr Challoner's from Aylesbury is unlikely to end in an offer unless your score is very high. Know your realistic catchment before you pin your hopes on a specific school.
How to prepare
The Bucks Test uses GL Assessment format, which is the most widely practised format in the country. CGP and Bond publish structured practice series for both content and full papers. Pretty much every major 11+ publisher has GL-style material available.
The timeline that tends to work is starting structured practice in Year 5, building familiarity with question types through spring, working on speed across the summer, and doing timed full mock papers in August. By September, the test should feel familiar rather than frightening.
So what catches Bucks children out most? Pace. The reasoning sections reward fluent pattern recognition. A child who plods through questions methodically will leave some unanswered. That's not a reflection of intelligence. It's a reflection of practice. Timed work needs to be built in from at least Easter of Year 5, not bolted on in August.
Maths content is often the easiest to prepare for because it aligns with what schools already teach. Children who are strong at primary maths tend to find those questions comfortable. English punctuation and grammar questions are trickier because they test technical knowledge most Year 5 classroom work doesn't consolidate. Worth doing specific work on comma use, apostrophes, tenses and word classes rather than assuming reading widely covers it.
Do you need a tutor?
Plenty of Bucks families use tutors. Plenty don't. Whether it helps depends on your child and your willingness to structure home practice yourself. A good tutor identifies specific weak areas and works on them. A less good tutor runs generic weekly sessions that don't move the needle.
If you can commit to doing structured practice at home and your child responds well to you, a tutor isn't necessary. If home practice becomes a daily argument, paying someone else to take that pressure off the parent-child relationship can be worth it on that basis alone. That's a practical reason, not a test-performance one, and it's fine.
FAQ
When does the Buckinghamshire Test actually happen?
Usually in the second or third week of September in Year 6. Both test days fall within a short window. Results come out in mid-October, in time for the secondary school application deadline at the end of October.
We live just outside Buckinghamshire. Can our child still sit the test?
Yes. Out-of-county children can register independently through the Buckinghamshire admissions portal. The registration deadline is usually at the end of June in Year 5. Children who register and pass are treated the same as in-county children for the test itself. School admissions still prioritise distance, so a strong pass from outside Bucks doesn't guarantee a place at an oversubscribed grammar.
What's the difference between a pass and getting into a specific grammar school?
A pass means your child scored 121 or above and is eligible for any Bucks grammar. Getting in is a separate matter decided by that school's admissions criteria. For non-super-selective schools, distance is usually the main factor. For super-selectives like Dr Challoner's Grammar, score within the pass group is what matters. Always check each school's admissions policy before you rank preferences on the application form.
Should we hold off preparing until we know if our child is likely to pass?
No. The way to find out if your child is likely to pass is to prepare, then assess how they're doing. Starting in Year 5 gives you time to build familiarity without pressure. You can check progress with a mock paper in spring of Year 5. If your child is miles off, you've still got time to work on it. If they're comfortably above, you can ease off and keep things ticking over. What doesn't work is waiting until the summer before Year 6 and trying to cram in three months.
