High Wycombe families effectively have six grammar schools to consider. For boys, the Royal Grammar School (RGS) dominates the reputation stakes, with John Hampden Grammar a genuinely strong alternative and Dr Challoner’s Grammar in catchment for families north of the town. For girls, Wycombe High is the local heavyweight, with Beaconsfield High and Dr Challoner’s High sitting within realistic reach. All six admit through the same Bucks 11+ and a qualifying score of 121.

Figures compiled from each school’s published results pages and Ofsted reports. All six require a standardised score of 121 in the Bucks 11+.
The Bucks 11+ Exam Explained
Definition — The Bucks 11+. Buckinghamshire runs a single Secondary Transfer Test used by all 13 grammar schools in the county, including every school on this list. The test has been delivered by GL Assessment since 2019, replacing the older CEM paper, and is sometimes informally called a “GL-CEM hybrid” because the familiarisation material still reflects both influences.
Children sit two multiple-choice papers on the same morning in September of Year 6. Each paper lasts roughly one hour and combines English, maths, verbal reasoning and non-verbal reasoning. Scores are age-standardised so an August-born child is not disadvantaged against a September-born peer.
Buckinghamshire Council states that a standardised score of 121 is required to qualify for a grammar school place. That is 10 points higher than Slough’s 111 threshold — the Bucks bar is genuinely harder to clear, which is why serious preparation matters more in High Wycombe than in many other selective areas.

Royal Grammar School, High Wycombe
RGS has the reputation, but parents overlook how competitive it actually is. The school is boys-only, state-funded, and unusually among Bucks grammars it also offers boarding at Fraser Youens House.
| Stat | RGS |
|---|---|
| Address | Amersham Road, High Wycombe HP13 6QT |
| Headteacher | Mr Philip Wayne |
| Pupils | ~1,409 |
| Y7 PAN | 186 |
| Gender | Boys (boarding option 11–18) |
| Ofsted | Good — ungraded inspection Feb 2025 signalled significant improvement |
| GCSE 9–7 (5-yr) | ~75% of entries |
| A-Level A*–B (2024) | 72% |
| Website | rgshw.com |
Who it’s for. Academically confident boys who thrive in a busy, sporty, traditional environment. The boarding house makes RGS genuinely viable for families further out — one of the few state grammar schools in England where that is an option.
Admissions reality. Day places go through the Bucks 11+. Boarding places run through a separate process. For day entry, distance within the designated area is the main oversubscription tiebreaker once a qualifying score is achieved, so postcode still matters. Oxbridge and Russell Group destinations are strong, and the 2025 A-Level cohort was described by the school as a landmark year.
Wycombe High School
Wycombe High is the pick of the High Wycombe girls’ grammars for most local families, with an Outstanding rating reaffirmed in April 2024.
| Stat | Wycombe High |
|---|---|
| Address | Marlow Hill, High Wycombe HP11 1TB |
| Headteacher | Mrs Nicola Renyard |
| Pupils | ~1,361 |
| Y7 PAN | 192 |
| Gender | Girls (co-ed sixth form) |
| Ofsted | Outstanding (April 2024) |
| 2024 GCSE 9–7 | 68% of entries, 46% at 9–8 |
| 2024 A-Level | 19% A*, >50% A*–A, >75% A*–B |
| Website | whs.bucks.sch.uk |
Who it’s for. Ambitious girls who want a high-performing academic environment without the pressure-cooker feel of some superselectives. Inspectors specifically praised the “high level of trust between staff and pupils.”
Admissions reality. Wycombe High is one of the few Bucks grammars with a formal two-part catchment. Area A (High Wycombe, Marlow, Stokenchurch) has priority over Area B (Maidenhead and surrounding areas). Qualifying disadvantaged girls are admitted first, then Area A catchment, then distance out to roughly 11.7 miles in recent years. If you live outside Area A, your daughter will need both a qualifying score and proximity on her side.
John Hampden Grammar School
John Hampden sits next door to Wycombe High on Marlow Hill. It is the under-rated boys’ option — a school that punches above its reputation and is often a better fit than RGS for boys who want grammar-school rigour without boarding-school bustle.
| Stat | John Hampden |
|---|---|
| Address | Marlow Hill, High Wycombe HP11 1SZ |
| Headteacher | Miss Tracey Hartley |
| Pupils | ~1,271 |
| Y7 PAN | ~180 |
| Gender | Boys |
| Ofsted | Outstanding (September 2022) |
| Progress 8 | +0.69 (top 25% nationally) |
| 2024 GCSE 9–7 | 71.3% of entries |
| 2024 A-Level A*–B | 70.8% |
| Website | jhgs.bucks.sch.uk |
Who it’s for. Boys who want the #BeMore ethos — ambitious, kind, confident — in a mid-sized school with a strong PE and STEM tradition. University destinations include Oxford, Cambridge, Bath, Loughborough and Bristol.
Admissions reality. Bucks 11+, distance-based oversubscription, priority for looked-after children. Because Marlow Hill puts JHGS and Wycombe High on the same campus complex, families often have siblings split across the two — which can simplify school-run logistics.
Beaconsfield High School
Beaconsfield High sits 20 minutes east of High Wycombe and is in realistic reach for families in Loudwater, Wooburn and Flackwell Heath. According to Ofsted (inspected December 2024), it remains Outstanding.
| Stat | Beaconsfield High |
|---|---|
| Address | Wattleton Road, Beaconsfield HP9 1RR |
| Headteacher | Ms Emma Jay |
| Pupils | ~1,269 |
| Y7 PAN | 180 |
| Gender | Girls |
| Ofsted | Outstanding (December 2024) |
| 2025 GCSE 9–7 | 71% (23% at grade 9) |
| 2025 A-Level | 50% A*/A, 81% A*–B |
| National rank | 35th among UK grammars (2025 GCSE) |
| Website | beaconsfieldhigh.school |
Who it’s for. Girls who want the “dare to be remarkable” culture Ofsted singled out, with character development weighted as heavily as results. Strong in humanities and sciences, with regular Medicine and Dentistry placements.
Admissions reality. Tight catchment — typically 4 to 5 miles. Distance is the main oversubscription criterion, so Beaconsfield High is realistically on the table for families east of High Wycombe town centre but much harder from Booker or Sands without a high 11+ score.
Dr Challoner’s Grammar School
Dr Challoner’s Grammar is in Amersham and has been part of the HW family consideration set for decades, particularly for families in the Hazlemere, Holmer Green and Penn corridor.
| Stat | Dr Challoner’s Grammar |
|---|---|
| Address | Chesham Road, Amersham HP6 5HA |
| Headteacher | Mr D Atkinson |
| Pupils | ~1,368 |
| Y7 PAN | 186 |
| Gender | Boys (co-ed sixth form) |
| Ofsted | Outstanding (November 2024) |
| 2025 GCSE 7+ | Two-thirds of entries at grade 7+ |
| 2025 A-Level | 64% A*/A, 87% A*–B |
| Website | challoners.com |
Who it’s for. Boys targeting strong A-Level outcomes with a proper Oxbridge pipeline. Challoner’s values — “aspiration, kindness and resilience” — translate into a school that is academically serious without being brutal.
Admissions reality. Bucks 11+, distance-based, sibling priority. The effective catchment pulls from Amersham, Chalfont, Beaconsfield, Great Missenden and the northern edge of High Wycombe. Transport matters: the A413 and the Metropolitan line make it a workable commute from the HW27 side of town.
Dr Challoner’s High School
The sister school in Little Chalfont had the standout 2025 GCSE results of the six schools in this guide.
| Stat | Dr Challoner’s High |
|---|---|
| Address | Cokes Lane, Little Chalfont HP7 9QB |
| Headteacher | Mr Alan Roe |
| Pupils | ~1,358 |
| Y7 PAN | 180 |
| Gender | Girls |
| Ofsted | Outstanding (November 2023) |
| 2025 GCSE 9–7 | 83% (35% at grade 9, 62% at 9–8) |
| 2025 A-Level | 57% A*/A, 84% A*–B |
| Website | challonershigh.com |
Who it’s for. Academically confident girls — the school is, in its own words, “massively oversubscribed.” Strong in Modern Languages and Humanities, with excellent Medicine, Law and Veterinary Science pipelines.
Admissions reality. Tight catchment covering Little Chalfont, Amersham, Chalfont St Peter and surrounding areas. Families in the north of High Wycombe can make it work, but families south of the A40 will find distance works against them.
How to Choose the Right School for Your Child
Most High Wycombe parents overthink the school and under-think the preparation. A few honest questions cut through most of the noise:
1. What’s your postcode? Distance decides most oversubscription tiebreakers. Put your home postcode into each school’s catchment map before you fall in love with a reputation.
2. Single-sex or co-ed? Of the six, only the two Challoner’s schools offer co-educational sixth form (for Dr Challoner’s Grammar) — everything else is single-sex throughout. This matters more to some children than others.
3. Superselective or supportive? A “superselective” grammar school is one where demand far exceeds places, so a bare 121 is rarely enough. RGS, Wycombe High and Dr Challoner’s High sit nearer that end. Beaconsfield High and John Hampden tend to be more forgiving on score once catchment is met.
4. What does your child actually want? Visit every open evening you can. A school that works for your neighbour’s child may feel wrong for yours within five minutes of walking the corridors.

FAQ
What score do I need in the Bucks 11+ to get into a High Wycombe grammar school? A standardised score of 121 is the qualifying threshold for every Bucks grammar, including RGS, Wycombe High and John Hampden. For superselective schools like RGS and Dr Challoner’s High, aim for 130+ in practice to build a genuine margin — 121 alone often isn’t enough once catchment runs out.
Is the Bucks 11+ the same test as Slough’s? No. Bucks uses a single paper run by GL Assessment with a qualifying score of 121. Slough uses the Slough Consortium 11+, also GL Assessment, but with a lower qualifying score of 111. The exams test similar skills but the bar is meaningfully higher in Bucks.
Which High Wycombe grammar school is the most competitive? RGS High Wycombe is the most famous, but Dr Challoner’s High and Wycombe High are often harder to get a place at once catchment is applied. All three are functionally superselective for families outside their immediate priority area.
Can my child sit the 11+ for multiple Bucks grammars at once? Yes. The Bucks 11+ is a single county-wide test. One score is shared with every Bucks grammar school you list on your Common Application Form. You do not sit the exam again for each school.
When should we start 11+ preparation for the September 2026 exam? Ideally at the start of Year 5, so your child has 12 months of structured practice before sitting the test. If you’re starting later, five to six months of focused work at our centre can still produce a qualifying score — but it has to be consistent.
Does TSA only help with 11+? No. We support Bucks families from 11+ through KS3, GCSE and A-Level. Many of our Year 6 students stay with us through their whole school career at RGS, Wycombe High or John Hampden.
