180 places for boys, qualifying score 121, test date 10 September 2026 — everything parents need to know
Book a Free ConsultationJohn Hampden Grammar School (JHGS) is a selective state grammar school for boys aged 11 to 18, located on Marlow Hill in High Wycombe, Buckinghamshire. It admits 180 boys into Year 7 each year via the Buckinghamshire Secondary Transfer Test (STT), administered by GL Assessment. The school was founded in 1893, holds Outstanding status at Ofsted, and is one of 13 grammar schools within The Buckinghamshire Grammar Schools (TBGS) consortium. Entry is competitive: boys must achieve the qualifying standard on the STT and, where the school is oversubscribed, meet the priority area and admissions criteria. This guide covers the test format, 2026 key dates, priority areas, admissions criteria, and how to structure preparation effectively for John Hampden and the Buckinghamshire grammar system.
John Hampden Grammar School takes its name from John Hampden, the 17th-century Buckinghamshire parliamentarian and civil war leader who was born in the county. The school has operated as a selective boys' grammar school since 1893, making it one of the older grammar schools in Buckinghamshire and one with over 130 years of continuous operation as a selective institution.
The school is located on Marlow Hill, High Wycombe, Buckinghamshire, HP11 1SZ. It caters for boys from Year 7 through to the sixth form and has a strong tradition of both academic achievement and extracurricular engagement. The school is known for its law society, engineering activities, and photography club, alongside the full range of academic subjects and sports. It is Outstanding-rated by Ofsted across all areas.
John Hampden is one of two boys' selective state grammar schools in the High Wycombe area. The other boys' state grammar in High Wycombe is Royal Grammar School (RGS), which is an independent grammar school and not part of the state-funded TBGS consortium. Families sometimes confuse the two. John Hampden Grammar School is a state school, meaning it charges no fees. RGS High Wycombe is independent and fee-paying. For the 11+ state grammar school route in High Wycombe, John Hampden and Wycombe High School (girls) are the two relevant TBGS schools.
The school is part of The Buckinghamshire Grammar Schools consortium alongside the other 12 state grammar schools in the county. All Year 7 entry is via the shared STT, and a boy who passes the STT is eligible to apply to any of the 13 schools. He does not sit a separate John Hampden-specific exam.
The Buckinghamshire Secondary Transfer Test (STT) is the shared entrance assessment used by all 13 Buckinghamshire grammar schools. A boy who passes the STT is eligible to apply to any of the 13 schools; there is no school-specific exam for John Hampden Grammar School. The test date for 2027 entry is Thursday 10 September 2026, with a practice session on Tuesday 8 September 2026.
The test consists of two papers, each lasting approximately 60 minutes, with a break between them. Both papers are entirely multiple-choice and administered by GL Assessment. Scores are age-standardised and combined to produce a Secondary Transfer Test Score (STTS). The weighting across the two papers is: 50% verbal ability, 25% numerical ability, and 25% non-verbal reasoning.
Paper 1 tests verbal skills across three components: English comprehension (reading an unseen passage and answering comprehension questions), technical English (grammar, punctuation, and sentence structure), and verbal reasoning (word codes, analogies, letter sequences, and language pattern questions). Paper 2 tests non-verbal and numerical skills: mathematics (Key Stage 2 curriculum topics with an emphasis on problem-solving and multi-step reasoning) and non-verbal reasoning (shapes, spatial patterns, matrices, and abstract sequences).
Age-standardisation means that a boy born in August is not penalised compared to one born in September. The qualifying standard is typically a standardised score of 121, though this can vary slightly from year to year based on overall cohort performance across the county. Reaching 121 qualifies a boy to apply; it does not guarantee a place at John Hampden specifically. Oversubscription criteria determine which qualifying boys receive places at each individual school.

Each year, approximately 9,500 children across Buckinghamshire sit the Secondary Transfer Test to compete for around 1,900 grammar school places across all 13 schools. This gives a county-wide pass rate of roughly one in five children who sit the test. John Hampden Grammar School offers 180 of those places. The pool of applicants qualifying for John Hampden is further shaped by its priority areas: boys in Priority Area A are given preference over those in Priority Area B, and boys outside both priority areas must typically score well above 121 to stand a realistic chance of a place.
High Wycombe is one of the larger towns in Buckinghamshire, and demand for John Hampden places is consistently high. The school draws applications from boys in High Wycombe, Marlow, Beaconsfield, Gerrards Cross, and surrounding villages in south Buckinghamshire, as well as from families in parts of Berkshire, including Maidenhead, who fall within Priority Area B. The cross-county draw from Berkshire is notable: families in Maidenhead who do not have access to a Berkshire grammar school sometimes register their sons for the Buckinghamshire STT specifically to target John Hampden.
Boys who live in Priority Area A and achieve 121 or above have a strong prospect of a place in most years, though this is not guaranteed and depends on the number of qualifying boys in that area each year. Boys in Priority Area B need to score well to ensure they are competitive with in-catchment applicants. Boys from outside both priority areas who score 128 or above are generally in a strong position. The best indicator of likely admission for any individual family is to review the school's previous year's admissions data, which shows the minimum score at which offers were made in each priority category. This data is available from the school on request.
John Hampden Grammar School uses a priority area system that functions differently from the simple catchment model used by some Buckinghamshire grammar schools. Rather than a single in-catchment or out-of-catchment distinction, JHGS operates two geographically defined priority bands that determine the order in which qualifying boys are considered for places.
Priority Area A covers the main areas of High Wycombe, Stokenchurch, Marlow, Beaconsfield, and Gerrards Cross, together with surrounding villages. Boys living in Priority Area A who have reached the qualifying standard are prioritised in admissions above boys from Priority Area B, subject to higher-priority criteria (EHCPs, looked-after children, Pupil Premium, siblings, medical/social need, and staff children) being applied first.
Priority Area B covers parts of south Buckinghamshire not in Priority Area A, as well as parts of Berkshire: Maidenhead, Taplow, Stoke Poges, Iver Heath, and parts of Burnham. Priority Area B boys are considered after all Priority Area A qualifying boys have been accommodated. In years where Priority Area A qualifying boys are numerous relative to the 180 places, Priority Area B boys may not receive offers even if they have scored well above 121.
The full oversubscription criteria when the school is over-subscribed with qualifying applicants apply in this order: first, children with an Education, Health and Care Plan naming the school; second, looked-after and previously looked-after children; third, boys in Priority Area A receiving Pupil Premium; fourth, siblings of current pupils in Priority Area A; fifth, boys with exceptional medical or social needs (with written evidence) in Priority Area A; sixth, children of current JHGS staff in Priority Area A; seventh, all other qualifying boys in Priority Area A, in distance order; eighth, Priority Area B in the same sub-criteria order; ninth, all other qualifying boys by distance. Parents should always download the current year's published admissions policy from the John Hampden Grammar School website or from Buckinghamshire Council to confirm the exact current criteria.
High Wycombe sits in the heart of south Buckinghamshire and has a strong tradition of selective education. Understanding the local grammar school landscape helps families make well-informed decisions when listing preferences on the Common Application Form.
The state grammar school options for boys in High Wycombe and south Buckinghamshire are centred on John Hampden Grammar School. Wycombe High School is the girls' state grammar school in High Wycombe, also part of TBGS and using the same STT. A family with both a son and a daughter may be applying to both schools simultaneously in the same year if children are in the same year group. Both John Hampden and Wycombe High School are Outstanding-rated and consistently achieve strong results.
Families in High Wycombe who also consider south Bucks geography will be aware of Beaconsfield High School for girls (see our Beaconsfield High School 11+ guide), which is another TBGS girls' grammar school within practical distance. For boys, John Hampden is the principal state grammar option in this part of the county. Further afield in Buckinghamshire, families may also consider Dr Challoner's Grammar School in Amersham for boys (see our Dr Challoner's Grammar School guide).
It is also worth noting that Royal Grammar School High Wycombe (RGS Wycombe) is often discussed alongside John Hampden but is categorically different: RGS is an independent school that charges fees and runs its own separate entrance assessment. It is not part of the TBGS consortium and does not use the Buckinghamshire STT. Families considering RGS should prepare separately for that school's own entry process. For the state grammar school route in High Wycombe, John Hampden is the relevant destination for boys.

Effective preparation for John Hampden Grammar School and any Buckinghamshire grammar school is built over 12 to 18 months, not compressed into the final few weeks before the September test. Boys who begin preparation in Year 4 or the start of Year 5 have time to develop genuine understanding, build stamina, and enter the test in a composed, well-prepared state. Boys who begin in the summer term of Year 5 consistently feel rushed, anxious, and underprepared on test day.
Year 4: Begin building foundations informally. Focus on reading widely across fiction, non-fiction, and newspapers to develop vocabulary range and comprehension stamina. Strengthen mental arithmetic and number fluency. Introduce verbal reasoning question types gently so they become familiar rather than intimidating. Start non-verbal reasoning with simple shape and pattern exercises. Formal timed preparation is not necessary at this stage. The aim is gradual, positive exposure.
Year 5 Autumn Term: Begin structured preparation with a regular schedule. Cover all five STT components systematically: comprehension, technical English, verbal reasoning, non-verbal reasoning, and maths. Explain the logic of every question type explicitly before drilling answers. A boy who understands why an answer is correct will consistently outperform one who has only seen the correct answer on a mark scheme without understanding the reasoning.
Year 5 Spring Term: Move to targeted work on weaker areas. By the spring term, most boys have a clear picture of their relative strengths and weaknesses. Common weak areas are technical English (grammar and punctuation questions that are not typically drilled in primary schools) and the higher-order verbal reasoning question types. Use this term to address specific gaps directly, rather than continuing to cover areas where the boy is already performing well.
Year 5 Summer Term: Introduce timed full-length practice tests under realistic test conditions. Sit at least one complete STT-style test per month. Review every question missed, including any where the correct answer was guessed without understanding. Track scores across multiple papers to build a clear sense of progress and to identify any areas that still need attention before the test itself.
Year 6 (before September test): Fine-tune and consolidate. Continue timed maths practice to ensure automatic recall of number facts. Maintain regular reading to sustain vocabulary and comprehension stamina. Keep the overall volume of preparation steady rather than escalating dramatically in the final weeks. In the fortnight before the test, reduce formal preparation and focus on rest and confidence. The goal is to enter the test on 10 September 2026 feeling ready, rested, and calm rather than exhausted from last-minute cramming.
Preparing your son for John Hampden Grammar School?

Our tutors observe consistent patterns among boys who score well above the qualifying standard for John Hampden Grammar School. These differences are not primarily about innate academic ability. They reflect preparation quality, consistency, and specific habits developed over the year or more before the test.
They have specifically practised technical English. Technical English is the component most commonly underweighted in preparation plans. Many families invest heavily in verbal reasoning practice and maths but give little attention to the grammar, punctuation, and sentence structure questions in Paper 1. Boys who have worked through targeted technical English exercises, learning to identify sentence errors and select correctly punctuated options, are noticeably more confident in Paper 1 and score more consistently across all three of its components. Since Paper 1 counts for half the total test score, this matters significantly.
They understand verbal reasoning question types before encountering them in the test. GL Assessment verbal reasoning uses a consistent set of formats: word codes, letter sequences, number analogies, and odd-one-out questions. Boys who have been explicitly taught each format, with the underlying logic explained and worked examples demonstrated, consistently outperform boys who have only guessed their way through practice papers and checked the answers. Understanding why an answer is correct is more valuable than simply knowing that it is correct.
They have read widely and consistently. The comprehension section of Paper 1 rewards reading breadth more than any specific exam preparation technique. Boys who read regularly across a range of material, including fiction, non-fiction, quality newspapers, and longer articles, develop the vocabulary range and reading speed needed to process an unseen passage quickly under time pressure. This habit cannot be manufactured in the final weeks before the test. It is built over months of consistent reading.
They practise maths in timed conditions. The maths section of Paper 2 draws on Key Stage 2 curriculum content but is taken under significant time pressure. Boys who have drilled maths in timed sessions, working through problem sets against the clock, develop the automatic number recall and the habit of checking working that produces reliable scores. Boys who have only done untimed maths practice at home find the paced nature of Paper 2 disproportionately stressful on test day.
Their families have kept preparation calm and consistent. The boys who perform closest to their ceiling on test day are those whose families have maintained steady encouragement without generating excessive pressure around scores or outcomes. A well-prepared boy who walks into the test on 10 September 2026 having followed a consistent programme throughout Year 5 is in the best possible position. The STT is a significant assessment, but the children who perform best on the day are those who have been prepared thoroughly and calmly, not those who have been drilled intensively in the final fortnight.
John Hampden Grammar School admits 180 boys into Year 7 each September. For 2027 entry, the Buckinghamshire Secondary Transfer Test takes place on Thursday 10 September 2026. A practice session is available on Tuesday 8 September 2026. Boys at Buckinghamshire state-funded primary schools are registered automatically; boys at independent schools or outside Buckinghamshire must register manually between Friday 1 May 2026 and Tuesday 2 June 2026. Test results are sent to parents on Thursday 9 October 2026, and the Common Application Form for school preferences must be submitted to your home local authority by Saturday 31 October 2026.
John Hampden Grammar School uses two priority areas in its admissions criteria. Priority Area A covers High Wycombe, Stokenchurch, Marlow, Beaconsfield, and Gerrards Cross, along with surrounding villages. Priority Area B covers Maidenhead, Taplow, Stoke Poges, Iver Heath, and parts of Burnham. Boys living in Priority Area A are given preference over those in Priority Area B when the school is oversubscribed. Boys outside both areas can still apply and may receive places if spaces remain after Priority A and B applicants have been accommodated. The full admissions policy with current area boundaries is available from the school and Buckinghamshire Council.
The Buckinghamshire Secondary Transfer Test consists of two papers, each approximately 60 minutes long, both entirely multiple-choice. Paper 1 covers verbal ability: English comprehension, technical English (grammar and punctuation), and verbal reasoning. Paper 2 covers non-verbal reasoning (shapes, patterns, and matrices) and mathematics (Key Stage 2 topics with a focus on problem-solving). The weighting is 50% verbal ability, 25% non-verbal reasoning, and 25% mathematics. Results are age-standardised before being combined. The qualifying standard is a standardised score of 121, though this can vary slightly from year to year depending on cohort performance across the county.
Most boys who successfully secure places at John Hampden Grammar School begin structured 11+ preparation around 12 to 18 months before the September test. For the 2026 test, that means starting in Year 4 or the autumn term of Year 5. Starting in Year 4 allows time to build strong foundations across verbal reasoning, technical English, non-verbal reasoning, and mathematics without excessive pressure. Starting in the summer term of Year 5, just weeks before the test, leaves boys underprepared and anxious. The most effective programmes involve regular short sessions, with at least one timed full-length practice test per month from Year 5 autumn term onwards.
John Hampden Grammar School and Wycombe High School are the two selective state grammar schools in High Wycombe, serving different genders. John Hampden is boys-only, while Wycombe High School is girls-only. Both schools are part of The Buckinghamshire Grammar Schools consortium and use the same Secondary Transfer Test, so a child who qualifies may apply to both. Both carry strong academic reputations and are heavily oversubscribed each year. Families with sons who qualify will typically list John Hampden as a first or second preference, depending on distance and priority area. Both schools draw from overlapping catchment areas in High Wycombe and south Buckinghamshire.
