Few independent schools change their name and their gear in the same year. RGS Surrey Hills did both. The school that generations knew as Box Hill School, founded in 1959 in the village of Mickleham near Dorking, joined the Reigate Grammar School Group and relaunched under its new name in 2025. The bones are the same: a small, co-educational day and boarding school for ages 11 to 18, set in roughly 40 acres of Surrey countryside in the shadow of Box Hill itself, with a founding-member place in the Round Square movement and an international community drawn from around 30 countries. What is new is the backing of one of the region's most established independent groups. Around 350 students fill a school built for 450, which keeps class sizes small and the tone personal. Both A-level and the International Baccalaureate Diploma run side by side in the sixth form.
The DNA here is unusual, and it explains a lot. Box Hill School was started by Roy McComish, a house and art master who had taught at Gordonstoun under the German educator Kurt Hahn, and the school became one of the family of institutions built on Hahn's belief that character is forged through challenge, service and the outdoors as much as through the classroom. That lineage made the school a founding member of the Round Square Conference of Schools, and the Round Square IDEALS still anchor daily life: internationalism, democracy, environmentalism, adventure, leadership and service.
You can read that ethos in the geography. The main building, Dalewood House, is a Victorian house from 1883 designed by the architect John Norton, and the wider estate spreads across hillside grounds that lend themselves to expedition and outdoor learning rather than a tight urban footprint. The community is genuinely international: boarders and day students from roughly 30 countries share houses and classrooms, which gives the place a worldly, unpretentious feel.
The relaunch matters for parents weighing the school now. Under the Reigate Grammar School Group, RGS Surrey Hills keeps its own leadership, staff, curriculum and identity while drawing on the resources of a larger family. The group has been explicit that the two schools remain distinct: Reigate is a selective grammar by reputation, while Surrey Hills is non-selective and broadly inclusive, offering, in the head's words, choice to local families. Headmistress Hayley Robinson, who took the substantive post in 2024, has framed the change as staying true to the school's spirit while aiming higher.
For a prospective parent, the practical effect is reassurance with ambition attached. The Reigate Grammar School Group is a known quantity in this part of Surrey, and its leadership has stated that both schools will remain fully independent in character and admissions while sharing the same broad ambitions for their students. That gives RGS Surrey Hills the security of group resourcing without surrendering the small-school feel that has defined it for more than six decades. The buildings, the cohort, the staff and the Round Square outlook all carry over, so this is a school continuing under new stewardship rather than starting from scratch.
For GCSE outcomes, RGS Surrey Hills is ranked 592nd in England and 2nd in Dorking, a proprietary FindMySchool ranking built from official results. That places the school above the England average, within the top 25% of schools in England, and second among its local peers. The school is non-selective, so these results are earned across a mixed-ability intake rather than a filtered one, and the local standing is the headline figure worth holding onto. Strong GCSE grades feed directly into a sixth form that runs both A-levels and the IB, so the foundation built at 16 leads into a genuine choice of routes at 18.
Because the school admits across the ability range, the value it adds matters as much as the raw grades. Small classes, a broad curriculum that balances academic, creative and practical subjects, and close subject knowledge from teachers all feed into how students progress from their starting points. Parents looking to compare these figures against neighbouring schools can line them up side by side using the FindMySchool local hub comparison tool.
It is worth being clear-eyed about scale when reading these numbers. The cohort sitting GCSEs is modest, in keeping with a small school, so RGS Surrey Hills cannot lean on the volume effects that flatter much larger schools in the tables. Being placed second in Dorking and inside the top quarter of schools in England, from a non-selective starting point, is therefore a stronger result than the raw position alone suggests. The broad subject offer, including creative and practical routes alongside the academic core, also means the grade profile reflects a genuinely mixed-ability intake rather than a narrow, exam-focused one.

Teaching here is built around small groups and subject specialists who clearly enjoy their disciplines. Lessons are well planned and pitched to a mixed-ability room, with students who have additional needs, including those with special educational needs and English as an additional language, brought into the work rather than set apart from it. Pupils respond to this with genuine independence and self-drive, taking ownership of their learning rather than waiting to be led.
The curriculum is deliberately broad. Academic subjects sit alongside design, music, art and sport as equal parts of the timetable, in keeping with the Hahnian idea that the whole person is being educated, not just the exam candidate. The sixth form widens the offer further by running both A-level and the IB Diploma, so students can choose between depth in three or four subjects and the breadth of six. One caution worth noting: tracking of pupil progress using baseline data has not historically been consistent across the whole curriculum, an area leaders have been working to tighten.
Around 58% of the most recent leaving cohort progressed to university, from a sixth-form group of roughly 48 students. A small number moved into employment. The destinations are international as often as they are domestic, reflecting a student body that arrives from around the world and frequently returns to it.
At the most competitive end, the school has sent students to Cambridge: in the most recent year recorded, two students applied to Oxbridge, one received an offer, and that place was taken up at Cambridge. These are small numbers, as you would expect from a school of this size, and they should be read as evidence that the route is open and supported rather than as a high-volume pipeline. For a non-selective school of around 350 students, getting a student through to Cambridge is a meaningful result. Dedicated careers and university guidance runs through the sixth form, including support for applicants to courses with extra hurdles.
The dual-pathway sixth form shapes where students end up. IB Diploma graduates are well placed for international universities as well as those in England, while A-level students follow the more familiar route to British institutions. Because the school recruits internationally, a meaningful share of leavers head to universities overseas each year, and the destinations list reads less like a single regional pipeline and more like a map. Parents wanting the precise breakdown for a given year should ask the school for its latest leavers' destinations, which it publishes for prospective families.

The sixth form is where the school's dual-pathway character is clearest. Students can take A-levels or the full IB Diploma, two genuinely different routes to the same universities, which is rare in a school this size and a real point of difference for families who already know which model suits their child.
On A-level outcomes, RGS Surrey Hills is ranked 1,085th in England and 3rd in Dorking, a FindMySchool ranking derived from official results. That is solid performance, in line with the middle 35% of schools in England, with local strength behind two Dorking neighbours. In the most recent results, around 28% of entries were graded A*-A and roughly 54% reached A*-B. The A*-B figure runs ahead of the England average of about 47%, which is a fair reflection of a school that gets strong work out of a broad cohort rather than cherry-picking the top of the ability range at entry.
Entry to the sixth form is by interview and assessment, with standard expectations around GCSE grades in chosen subjects; the admissions team advises families on whether A-level or the IB is the better fit. The school recruits into Year 12 both from its own Year 11 and from outside, and the international intake means new faces arrive at 16 alongside students who have been there since Year 7. The EPQ and independent research culture sit naturally alongside the IB's extended essay, giving sixth formers practice at the kind of self-directed work universities reward.
The choice between the two pathways is the defining sixth-form decision here, and it is a real one. A-levels let a student go deep into three subjects, which suits those with a clear specialism and a defined degree in mind. The IB Diploma keeps six subjects in play, adds the Theory of Knowledge course, the extended essay and a creativity, activity and service element, and rewards students who want to stay broad and are comfortable carrying mathematics and a language to 18. Running both under one roof is unusual for a school of around 350, and it lets families pick the model that fits the child rather than bending the child to the only model on offer.
Boarding is central to the identity here, not an add-on. The school runs full, weekly and flexi boarding alongside day places, so families can choose how much of the week their child lives on site, from two or three nights up to the full term. Inspectors found boarding to be well managed, with a thorough induction and secure arrangements, and boarders proud to belong to the community. With students from around 30 countries in residence, the boarding houses are where the school's internationalism is most tangible: evenings and weekends mix nationalities, languages and backgrounds in a way few day schools can replicate.
For families further afield, including overseas families, full boarding makes the school genuinely accessible. For local families, the flexi option is a practical middle ground, letting a child board for part of the week and come home for the rest. The rural Surrey setting is a draw for the outdoor and expedition side of school life, though distant families should factor in travel for exeats and shorter boarding patterns.
The international mix is one of the school's defining features and a reason many families choose it. Living and learning alongside peers from around 30 countries builds the kind of cultural fluency that is hard to manufacture in a homogeneous day school, and it feeds directly into the Round Square ethos of internationalism. Induction is thorough, which matters when a proportion of boarders arrive each year from overseas, and the houses are organised to settle newcomers quickly into the rhythm of school and weekend life.
RGS Surrey Hills is non-selective, but entry is by assessment and interview rather than open to all comers, with the main entry points at 11+ for Year 7, 13+ for Year 9, and 16+ for the sixth form. The process is designed to find students who will thrive in a small, busy, internationally minded school rather than to filter for the highest scorers, which fits the school's inclusive intake and its place in the local market as the non-selective alternative to its sister grammar.
Because the school is independent, places are arranged directly with the admissions team rather than through the local authority, and there is no fixed catchment line: day pupils come from across the Mole Valley and the wider Surrey area, while boarders come from much further afield. Registration and assessment timings are best confirmed directly with the school, as is the right entry point for a given child.
Open events run through the year. The school typically holds morning and evening open mornings in the summer term, with separate sixth-form-focused events, and offers private tours outside those dates by arrangement. Prospective families should check current dates with the school and book ahead, as places at open events are limited.
Pastoral care has been the school's most public area of growth, and the story is worth telling honestly. The ISI inspection of November 2023 identified weaknesses in behaviour, supervision and leadership oversight, and did not initially judge those standards as met. The school responded quickly. A progress-monitoring inspection in May 2024 confirmed that all three areas were then fully met: behaviour had improved considerably, bullying incidents were much less frequent, supervision of communal areas had been tightened with a clear staff rota, and an electronic system for recording concerns was being used consistently to spot and resolve issues early. Inspectors observed positive, respectful relationships between students and a calm, friendly atmosphere at breaks and mealtimes.
That turnaround coincided with new leadership and a strengthened senior team, and it is a fair signal of a school that acts decisively on criticism. Safeguarding has been effective throughout: recruitment checks are thorough, central records are properly kept, staff are appropriately trained, and systems for filtering and monitoring are in place. The PSHE programme, tutorial time and assemblies now reinforce kindness and clear behavioural expectations as part of daily routine.
Adventure and the outdoors are the school's first pillar, and they are not decorative. The Duke of Edinburgh's Award and a dedicated Expedition Week build the Hahnian have-a-go spirit into the calendar, sending students into the Surrey hills and beyond to test themselves outside the classroom. The hillside estate is the natural home for this, and it is one of the clearest threads running from the school's 1959 founding to its present day. The early students helped build parts of the school themselves, a have-a-go spirit the founder borrowed from his Gordonstoun training, and that practical, get-stuck-in attitude still runs through expeditions, service projects and outdoor education today. Sport is the second pillar, headlined by the Chelsea FC Football Pathway, an elite-level football programme that gives footballers professional coaching alongside their studies. Beyond football, rugby and a full fixture programme keep teams competing across the seasons, with the grounds offering space that many town schools lack.
The creative and performing arts form the third pillar. A dedicated creative arts faculty and performing arts and music programmes give students room to compete on stage and develop music, drama and design skills, and these opportunities to perform and create are a recognised strength of school life. The fourth pillar is internationalism itself, expressed through Round Square exchanges and service projects that take advantage of the school's global membership and connect students to partner schools around the world. Together these four strands, adventure, sport, the arts and a genuinely international outlook, give a small school an unusually wide co-curricular reach.

The school day follows a standard independent timetable, extended by boarding routines and an after-school co-curricular programme for day and boarding students alike. The school sits on the London Road near Mickleham, in the Mole Valley district of Surrey, roughly 45 minutes from London and close to Dorking and Box Hill, which makes it reachable for day families across the area and for boarders travelling from further afield. Families weighing the commute can use the FindMySchool map search to gauge travel time from home before booking a visit. Specific term dates, transport arrangements and minibus routes are best confirmed with the school directly.
A school in transition. The relaunch under the Reigate Grammar School Group is recent, and the longer-term shape of the school under new ownership is still settling. Families are buying into a clear direction and stronger backing rather than a long, unchanged track record under the current name. For most this is a positive, but it is worth understanding before committing.
Recent pastoral history. The November 2023 inspection found real weaknesses in behaviour and supervision before the school addressed them. The May 2024 follow-up confirmed full compliance, which is reassuring, but parents should ask leaders directly how the improvements have held since.
Small scale, by design. With around 350 students, the school offers intimacy and attention, but the breadth of subject choice, fixtures and cohort size will be smaller than at a large day school. That suits some children and not others.
Boarding commitment and travel. Boarding ranges from a couple of nights a week to full term, and the rural setting means distant families should plan for exeat travel. The flexi option softens this, but it is a genuine consideration for those further away.
RGS Surrey Hills is a small, international, outward-looking school with an adventurous Round Square soul and, now, the security of a respected group behind it. Its GCSE results place it second in Dorking and within the top 25% in England, its sixth form runs the rare combination of A-level and the IB, and its pastoral provision has come through a difficult inspection and out the other side with full compliance restored. It is best suited to families who want a personal, character-building, genuinely international education over the anonymity of a large school, and who value adventure, the arts and boarding flexibility as much as raw league-table position. The main caveat is timing: this is a school confidently remaking itself, so visit, ask how the recent improvements have bedded in, and judge the new chapter on what you see.
RGS Surrey Hills is a well-regarded small independent school near Dorking. Its GCSE outcomes rank 2nd in Dorking and within the top 25% of schools in England, and its A-level results run ahead of the England average for A*-B grades. After an ISI inspection in November 2023 flagged weaknesses in behaviour and supervision, a follow-up inspection in May 2024 confirmed all standards were fully met, and safeguarding has been effective throughout. It suits families who want a personal, international, character-led education.
For the 2026-27 year, day fees are around £9,415 per term for Years 7 and 8, £10,145 per term for Years 9 to 11, and £10,585 per term for the sixth form. Boarding costs more depending on the pattern chosen, from flexi boarding of two or three nights a week up to full boarding, which reaches roughly £15,670 to £19,110 per term depending on year group. Families should confirm current figures directly with the school.
Yes. Scholarships of up to 10% off fees are awarded for academic, music, sport, art and drama achievement at 11+, 13+ and sixth-form entry, based on assessment and interview. Means-tested bursaries are also available to help families who could not otherwise afford the fees, and a student can hold both a scholarship and a bursary at the same time.
The school takes day students alongside boarders, and offers full, weekly and flexi boarding so families can choose how much of the week their child lives on site. The boarding community is strongly international, with students from around 30 countries, which makes the houses a particularly diverse part of school life.
Yes. The sixth form runs both A-levels and the full International Baccalaureate Diploma, so students can choose between depth in a few A-level subjects or the broader six-subject IB. The admissions team advises families on which pathway best fits their child at the point of sixth-form entry.
Behaviour and supervision were areas of concern at the November 2023 inspection, but the school revised its policies, retrained staff, introduced a clearer supervision rota and adopted a consistent electronic system for recording concerns. A May 2024 follow-up confirmed considerable improvement, with calmer communal areas, fewer bullying incidents and positive relationships between students. Safeguarding has been judged effective throughout.
