The exam at a glance
For September 2028 entry, Dr Challoner’s Grammar School uses the Buckinghamshire Secondary Transfer Test as part of Buckinghamshire’s grammar-school admissions process. Year 7 applications are handled through Buckinghamshire Council’s co-ordinated admissions scheme rather than by the school alone.
The school’s own Year 7 admissions page confirms that children applying for grammar-school places in Buckinghamshire must take the Secondary Transfer Test. For the current published round, Buckinghamshire Council has set out two test dates in September for children in Year 6.
What is not safely confirmed for 2028 entry is the exact paper style, provider, tested subjects and delivery method. ElevenReady’s verified school data says these are not yet confirmed, and the official pages I found for Dr Challoner’s and Buckinghamshire Council do not provide enough detail to describe the format more precisely for 2028 entry. The safest advice is to treat this as the Buckinghamshire Secondary Transfer Test and check the school admissions page and Buckinghamshire Council’s testing pages as soon as registration opens for your child’s cohort.
In practical terms, families should expect the testing process to happen early in the autumn term of Year 6, followed by results before the secondary school application deadline. On the day itself, Buckinghamshire Council’s process normally involves children attending one of the published test sessions and then receiving their qualification outcome later in the autumn.
Registration and key dates
For Dr Challoner’s Grammar School, Year 7 admissions are administered through Buckinghamshire Council under the county’s co-ordinated admissions scheme. The school’s admissions page makes clear that applicants for grammar-school places need to complete the Buckinghamshire testing process, and the school also requires its own Supplementary Information Form (SIF) from families relying on certain oversubscription rules linked to catchment.
For the most recently published Year 7 round on the school’s admissions page, the dates shown are:
- Secondary Transfer Test dates: 8 September 2026 and 10 September 2026
- Results released: 9 October 2026
- School SIF deadline for first-round allocations: 30 November 2026 at 4.00pm
Because you are preparing for 2028 entry, these are not your child’s live dates. They are the latest official dates currently published on the school’s page, so the sensible working assumption is that Buckinghamshire testing will typically take place in early September of Year 6, with results in early October, and any school SIF due later in the autumn term. Parents should watch Buckinghamshire Council’s admissions pages and the school’s Year 7 admissions page for the 2028 entry timetable.
What should you expect to do when registration opens?
- Register for the Buckinghamshire Secondary Transfer Test using Buckinghamshire Council’s published process for your child’s cohort.
- Check whether you need the school’s SIF. Dr Challoner’s says applicants considered under Rules 2, 3, 4 and 6 of its admissions policy, where catchment residence matters, must complete the school’s own SIF to confirm residency qualification.
- Keep copies of address evidence and any requested documents. The admissions policy and SIF are the places to check exact evidence requirements for your year.
- Submit your Common Application Form (CAF) through your home local authority by the national secondary application deadline in October of Year 6.

Who can apply: catchment and admissions
Dr Challoner’s Grammar School is a selective academy for boys aged 11 to 16, with a co-educational sixth form. For Year 7, the school offers 180 places.
The school says applications are handled on behalf of the Governing Body by Buckinghamshire Council through the co-ordinated admissions scheme. That means families must follow both the grammar-school testing process and the normal local-authority secondary application process.
Catchment matters here. ElevenReady’s verified admissions note, which matches the school’s admissions approach, is that applicants considered under Rules 2, 3, 4 and 6 of the school’s admissions policy and relying on residence in catchment must complete the school’s own Supplementary Information Form to confirm residency qualification.
The safest way to think about eligibility is:
- Your child must go through the Buckinghamshire grammar-school testing process.
- You must apply through your home local authority’s secondary application system.
- If you want the school to consider your child under catchment-related priority rules, you must also complete the school’s SIF by the published deadline for your entry year.
The school does not publish a Year 7 cut-off score, pass mark, allocation distance or competition figure on the sources reviewed here, so it is better not to rely on forum claims or old spreadsheets. If you want the exact wording of the oversubscription order for your year, read the current admissions policy on the school’s admissions page as soon as the 2028 documents are posted.
One point that does come through clearly is that grammar-school admissions in Buckinghamshire are competitive. The school’s website gives a specific warning only for late transfer, saying it receives a substantial number of registrations for a very small number of possible places. It does not give an equivalent published Year 7 application figure.
A month-by-month preparation plan
If your child is aiming for the Buckinghamshire Secondary Transfer Test in early September of Year 6, the key is calm, steady preparation rather than a last-minute rush. Because the exact 2028 test format is not yet confirmed on the official pages reviewed, this plan focuses on strong core skills, tidy habits and gradual familiarisation with timed work.
Year 4 summer term or Year 5 September: Keep it light. Around 1 to 1.5 hours a week is enough at first. Build reading stamina, secure arithmetic, times tables, basic reasoning habits and neat working. If your child is not yet a confident reader, that is the first priority.
Year 5 autumn term: Increase to 2 hours a week, split across short sessions. Focus on accuracy, not speed. Use short skills exercises, mental maths, vocabulary growth and careful comprehension. Start noting any recurring weaknesses, such as fractions, inference, or losing marks through rushed reading.
Year 5 spring term: Move to about 2 to 3 hours a week. Begin more structured practice in the skill areas most likely to matter in selective testing: secure arithmetic, problem solving, close reading, and reasoning from written information. Introduce short timed sections only after your child understands the underlying method.
Year 5 summer term: Work at 3 hours a week for most children, perhaps a little more in short bursts if they are coping well. This is the stage to bring in regular timed practice, but not every session. The aim is to learn pacing without making preparation feel like a permanent mock exam.
Summer holiday before Year 6: Keep momentum, but protect family time and energy. Around 3 to 4 hours a week is realistic for many children. Use one fuller practice session each week, review errors carefully, and spend the rest of the time patching gaps. If a child starts to tire, shorten sessions rather than pushing harder.
Late August to test week: Prioritise confidence and routine. Do one or two final timed papers at most, then taper. In the final week, focus on sleep, breakfast routine, simple review and calm reassurance. Avoid cramming.
A good rule is this: do not start full timed papers too early. For most children, the right point is once the core methods are reasonably secure, usually in the second half of Year 5. Before that, untimed accuracy work gives better returns.
Subject by subject: what to practise
Because the official sources reviewed do not confirm the exact tested subjects for 2028 entry, parents should avoid over-committing to any one published commercial format. The most sensible preparation is to strengthen the broad academic skills selective tests usually reward and then adapt quickly when Buckinghamshire publishes fuller familiarisation material for your child’s cohort.
English and reading
Practise fluent reading, understanding of meaning, inference, vocabulary in context and careful retrieval from a passage. Good habits include underlining key words, checking evidence in the text and answering exactly what was asked. Read a wide range of fiction and non-fiction, then discuss tone, viewpoint and tricky vocabulary.
Useful practice includes short comprehension tasks, summarising paragraphs in one sentence, explaining word meanings from context and spotting where an answer has gone beyond the text.
Mathematics
Build speed only on top of secure knowledge. Children should be very comfortable with the four operations, place value, times tables, fractions, decimals, percentages, ratio basics, simple algebraic thinking and multi-step word problems at primary-school level. Many pupils know the method but lose marks through misreading, skipped steps or weak mental arithmetic.
Strong practice includes mixed arithmetic, short problem-solving sets, mental maths drills and regular review of weak areas. Encourage your child to estimate first and check whether an answer is sensible.
Reasoning and problem solving
Even though the precise 2028 subject list is not confirmed, selective admissions tests often reward logical thinking, pattern spotting and careful handling of information. Practise puzzles that require method, elimination and attention to detail rather than guesswork. If your child meets an unfamiliar task type, teach them to stay calm, mark what they know and move step by step.
Good activities include code-breaking puzzles, sequencing, classifying information, comparing statements and solving short logic problems with a clear written method.
Writing and vocabulary habits
Where the precise assessment content is unknown, vocabulary growth is one of the safest investments. Read aloud together, collect ambitious but usable words, and revisit them in context. If your child writes regularly, focus on clear sentences, accurate punctuation and selecting evidence from what they have read, rather than writing long pieces for the sake of it.
As soon as Buckinghamshire Council releases official familiarisation guidance for the 2028 cohort, use that to narrow your practice and match the balance of skills more closely.
Practice papers and mock exams
Practice papers are most helpful when they are used to diagnose weaknesses, not just to generate scores. One paper a week, reviewed properly, is usually far better than several rushed papers with no follow-up.
A simple routine works well:
- Choose one paper or timed section.
- Mark it carefully.
- Sort mistakes into three groups: didn’t know, knew but rushed, and misread the question.
- Spend the next few sessions fixing those exact issues.
- Repeat with a fresh paper after a gap.
Mock exams can be useful later in Year 5 or the summer before Year 6 because they help children practise timing, focus and exam-room routine. They are less useful if taken too early, before your child has secure methods. If you do use mocks, treat the feedback as information, not a verdict.

Because the exact 2028 format is not yet confirmed on the official pages reviewed, keep an eye on Buckinghamshire Council’s familiarisation materials and be ready to switch to those as your main reference once published.
On the day
Children usually do best when the day feels predictable. In the week beforehand, make sure your child knows the basic routine: when to get up, what breakfast works well, what they are taking, and where they are going if Buckinghamshire Council has assigned a specific venue or session.
Practical steps that help:
- Pack everything the night before if the official instructions ask for it.
- Leave in good time so there is no sense of rushing.
- Keep conversation calm and ordinary on the journey.
- Remind your child that some questions will feel hard; that is normal in a selective test.
- Encourage them to listen carefully to instructions, keep an eye on time and move on if they get stuck.
The best final message is simple: read carefully, do the straightforward questions cleanly, and do not let one difficult section spoil the rest of the paper. Children often perform better when they know they are not expected to find every question easy.
After the test, try not to conduct a detailed post-mortem in the car. Offer food, a break and reassurance first.
After the exam: results, allocation and appeals
For the latest published Year 7 round on the school’s admissions page, Secondary Transfer Test results are released on 9 October 2026. For your child’s 2028 entry year, expect the same general sequence: test in early September, results in early October, then national secondary school applications and allocations in the usual admissions cycle.
After results are issued, families list school preferences through their home local authority’s application system. Buckinghamshire Council then handles the co-ordinated process for this school’s Year 7 admissions on behalf of the Governing Body.
If you are applying under one of the school’s catchment-related priority rules, do not forget the school’s own SIF deadline as well as the local-authority application deadline. Missing the SIF can affect how the application is ranked under the admissions rules.
If a child does not receive an offer, the usual next steps are to stay on the waiting list if available and consider an appeal. The exact appeal arrangements for your year should be checked on the school’s and local authority’s admissions pages, because procedural details can change. What matters most is using the official documents for your cohort rather than relying on previous years or informal advice online.
What has changed recently
The main clearly published update on the official school admissions page is the 2027 entry testing timetable, which sets the Secondary Transfer Test dates as 8 and 10 September 2026, with results on 9 October 2026. The same page also gives a 30 November 2026, 4.00pm deadline for the school’s SIF for first-round allocations.
I did not find an official announcement on the school or Buckinghamshire Council pages reviewed that confirms a new provider, new paper style, new tested-subject list or a change in Published Admission Number for 2028 entry beyond the current admissions information. Because ElevenReady’s verified directory states that the 2028 format and subjects are not yet confirmed, parents should wait for the school and Buckinghamshire Council to publish the next round’s documents before assuming anything has changed.
