Tonbridge Grammar School occupies a leafy 14-acre campus in the heart of Kent, a selective girls' grammar school that draws applicants from across the region through the competitive Kent Test. With approximately 1,050 pupils aged 11 to 18 (including boys admitted to the sixth form), the school has held Outstanding status under Ofsted scrutiny and maintains consistent ranking in England's top 2% of secondary schools.
The most striking recent development is the school's wholesale commitment to the International Baccalaureate (IB) Diploma for sixth form studies, replacing A-levels entirely from 2012. This decision has positioned Tonbridge as the highest-performing IB state school in the United Kingdom for the past decade, demonstrating that selectivity and innovation are not mutually exclusive. The school was named State Secondary School of the Year and IB School of the Year by the Sunday Times in 2014.
Physically, the school blends historic architecture with contemporary investment. The original Victorian hilltop building remains, now complemented by the Hands Building (2009), the IBarn (2015), and the Matthews Centre technology block (1996). A £2 million sports and recreation facility opened in 2018, creating genuine breadth in physical provision. The music facilities, refurbished as recently as 2015, occupy a dedicated wing that reflects the centrality of the arts to school life.
Entry is fiercely selective. Over 829 girls applied for just 180 places in recent years (admissions data shows a 4.6:1 applications-to-offers ratio). The Kent Test, administered to Year 6 pupils, sets a qualifying score of 332 aggregate with no individual component below 108. Even passing the exam does not guarantee entry; places are allocated first to looked-after children, then to girls scoring highest within the priority catchment area, with distance used as a tiebreaker for remaining places. This competitive environment shapes school culture profoundly.
The tone here is purposeful but not joyless. Pupils describe an environment where curiosity is expected and intellectual engagement rewarded. Girls are encouraged to question, debate, and think beyond the confines of the exam specification. Multiple named societies, the Debating Society, International Society, and STEAM club, provide evidence that learning extends well beyond the classroom into passionate, student-led inquiry.
The school's history is woven into daily life. Six house systems, Taylor, Fayerman, Arnold, Mitchener, Carey, and Debney, carry the names of former headmistresses and staff members who shaped the school across more than a century. This creates continuity and a sense that individual girls are part of a longer story. Pupils can walk past the Mitchener Hall (built as an annexe in 1974) or work in the Debney House office, named for Miss Joy Debney, a history teacher and senior staff member who served from 1954 to 1991. These named spaces carry gravitas.
Inclusion sits alongside selectivity. The school explicitly prioritises Pupil Premium allocation, reserving places for disadvantaged families. This reflects a deliberate philosophy that being selective about academic attainment need not mean excluding based on background. The sixth form explicitly became co-educational in 2002, and boys are now fully integrated, forming approximately one-third of Years 12 and 13. This shift modernised the school's culture without erasing its female heritage.
Behaviour expectations are clear. Ofsted reported that pupils "treat each other with kindness and care" and that they demonstrate genuine commitment to raising awareness of community issues and making a difference locally. The house system encourages peer mentoring, with older girls supporting younger cohorts through pastoral structures embedded across all six houses.
Staff stability matters here. Teaching roles attract experienced educators, many of whom have spent decades at the school. Subject specialists are invested in their departments, the music staff, for instance, have overseen a 25-year history of the Motet Choir, which celebrates meaningful milestones and generates school-wide musical culture.
Tonbridge Grammar consistently delivers exceptional GCSE outcomes. In recent examinations, 82% of all grades achieved fell in the top two categories (9-7), compared to the England average of 54%. This 28%age point margin is substantial and reflects the selective intake combined with high teaching quality.
The attainment score (measuring average achievement across a pupil's best eight subjects) reaches 79.3, compared to the England average of 46. The Progress 8 score, measuring growth from starting points, reaches +0.75, indicating that pupils make above-average gains even within this already-high-achieving cohort. This speaks to teaching quality that stretches top students rather than simply allowing them to coast on intake advantage.
The English Baccalaureate qualification (a measure of breadth covering English, mathematics, sciences, and languages) sees 90% of pupils achieve grades 5 and above, positioning the school within the elite band in England. Tonbridge maintains a broad curriculum expectation, encouraging modern languages and sciences alongside humanities.
Tonbridge Grammar ranks 100th in England for GCSE outcomes (FindMySchool ranking), placing it within the elite national tier (top 2%). Locally, it ranks 3rd among Tonbridge secondary schools, a position it has sustained across multiple examination cycles.
The sixth form data represents a seismic shift in school strategy. The decision to replace A-levels entirely with the International Baccalaureate Diploma Programme has generated remarkable results. At IB level, students achieving 38 points or above (on the maximum scale of 45) represent exceptional attainment. Tonbridge consistently sits in the top tier of IB schools globally.
The metrics here are striking: 22% of students achieve the A* grade (40-45 points), while 40% achieve grade A (35-39 points). Combined with the B-grade cohort (25%), this means 88% of entries fall in the top three grades, compared to the England average for A*-B at A-level of approximately 47%. The IB attracts a different assessment philosophy focused on coursework, extended essays, and theory of knowledge papers, rather than pure examination performance. Yet Tonbridge excels within this framework.
Tonbridge Grammar ranks 113th in England for A-level/IB outcomes (FindMySchool ranking), placing it in the top 4%. Within Tonbridge, it ranks 2nd for post-16 results.
The school's embrace of IB has consequences: it shapes curriculum breadth, extends the school day for internal assessments, and creates genuine international exposure through the IB curriculum philosophy.
In the 2023-24 cohort (118 leavers measured), 68% progressed to university, while 18% entered employment directly and 3% pursued further education qualifications. This profile reflects a school population where university progression is the norm, yet pathways remain diverse.
Six pupils in the measured cohort secured Oxbridge places (all Oxford; Cambridge acceptance was limited to one), a success rate of 5% among those applying. Named Oxbridge acceptances demonstrate strength: law, engineering, and classics all feature among successful candidates. Beyond Oxbridge, leavers regularly access Russell Group universities including Imperial College, Durham, Edinburgh, and Bristol, reflecting the quality of teaching in STEM subjects and humanities alike.
The careers programme explicitly structures progression planning, with dedicated staff providing guidance from Year 9 onwards. Work experience placements, industry partnerships, and visiting speakers embed career awareness throughout sixth form.

The curriculum here blends traditional academic structure with genuinely innovative elements. The IB Diploma Programme in sixth form demands breadth across sciences, humanities, and languages, a departure from the A-level model that allows specialisation into three or four subjects. Pupils navigating this transition require well-developed independent study skills and intellectual flexibility.
Lower school (Years 7-9) follows the national curriculum but with evident enrichment. Mathematics and computing are specialist designations for the school, reflecting a whole-school commitment to STEM. Girls take sciences separately (rather than combined) from age 11, enabling deeper specialist teaching. Modern languages begin in Year 7, with French, Spanish, and Mandarin offered, reflecting the school's international outlook.
The teaching approach emphasises inquiry and interpretation. History lessons centre on primary sources and debate rather than memorisation. English literature study incorporates creative writing alongside analysis. The sciences employ laboratory work as the foundation for understanding concepts, not as afterthought demonstration. Across departments, extended writing and independent research are embedded expectations, preparing girls effectively for university-level demands.
Teachers hold specialist qualifications in their subjects, with many pursuing advanced degrees or research interests. The staff directory reflects doctoral-level expertise in mathematics, physics, and chemistry, qualifications that signal genuine intellectual authority.
Assessment is frequent and feedback is detailed. Rather than relying solely on end-of-year examinations, teachers employ formative assessment throughout, enabling rapid identification of pupils requiring additional support or extension. The house system provides pastoral check-ins, allowing teaching staff to escalate wellbeing or academic concerns before they become critical.

University progression dominates the leaving destination picture. The Careers Programme explicitly targets research and interviews with universities throughout sixth form, enabling girls to develop applications with awareness of genuine course requirements and institutional fit.
Degree pathways reflect the school's academic strength in sciences and mathematics: engineering, medicine, and physics PhD routes are well-trodden. However, humanities graduate equally strongly into law, classics, modern languages, and history, suggesting balanced provision across the curriculum rather than STEM-only excellence.
Some leavers progress directly to employment, particularly in computing and mathematics fields where competitive industry salary offers rival university progression. Others pursue apprenticeships, though data suggests this remains a minority pathway for a school whose culture orients strongly toward higher education.
The International Baccalaureate emphasis means leavers emerge with research capabilities, extended essay experience, and genuine understanding of international educational systems, assets valued across universities.

This section represents the school's genuine richness and provides the evidence that selectivity and breadth coexist here.
The music programme commands dedicated facilities across the newly refurbished music wing. The Motet Choir, founded in the 1990s and approaching its 30th anniversary under Mr Adrian Pitts' direction, performs concerts across the school calendar and represents the school at external competitions. This is not peripheral activity; Motet rehearsals command status comparable to academic options, with girls balancing study commitment against choir participation.
Beyond the flagship ensemble, the school operates a Jazz Band, bringing a more informal ensemble spirit to the music curriculum. Recorder groups serve younger pupils, providing accessible musical entry points. Piano, violin, and woodwind tuition occur on-site, taught by specialist visiting musicians. The percentage of girls learning instruments, estimated at over 50%, substantially exceeds national averages, creating a school culture where musical participation feels normal rather than exceptional.
Annual musical productions combine orchestra, singers, and technical crew. Recent productions have included full orchestral accompaniment, suggesting investment in quality that extends beyond budgetary constraint.
Two separate drama performance spaces accommodate productions ranging from Year 7 to sixth form. Student-led dramas occur termly, enabling girls to experience theatre-making across directing, design, and performance roles. The scale of productions (typically 40-80 performers including ensemble) requires genuine organizational infrastructure, shaping opportunities for leadership development alongside creative expression.
Drama curriculum integrates with English literature study, enabling girls to experience texts (Shakespeare, modern playwrights) through embodied learning. External theatre visits reinforce this exposure.
The school maintains a dedicated STEAM Club, reflecting institutional commitment to science-technology-engineering-arts-mathematics integration. Named explicitly as a student club (not a curriculum addition), it suggests pupil-led inquiry into emerging areas like robotics, coding, and design thinking.
The Matthews Centre (opened 1996), commonly known as the Tech Block, houses computing laboratories with contemporary equipment. Computer Science is offered as a GCSE and IB subject, with specialist teaching from credentialed technologists. The school competed recently in computing challenges at regional and national levels, indicating that expertise extends beyond curriculum coverage.
The STEAM designation suggests that creative arts and STEM are deliberately linked, a philosophy evidenced in interdisciplinary projects combining design thinking with scientific method.
The #OurBigOutdoors facility, opened April 2018, represents a £2 million investment in sports infrastructure. The facility includes outdoor sporting areas, courts, and recreational spaces designed for accessibility rather than elite-only provision.
Netball, hockey, tennis, rounders, and athletics feature as core sports. Fixtures occur regularly against local grammar schools, with competitive squads selected from seasonal trials. The school maintains affiliated clubs for those seeking higher-level competition outside school, a pragmatic approach recognizing that elite sport often requires year-round, specialist coaching beyond school capacity.
Swimming continues to hold significance, with the school pool (opened 1963) undergoing refurbishment and remaining a focal point for PE lessons and galas.
The Debating Society provides opportunities for public speaking and argumentation beyond curriculum. Girls compete in inter-school competitions, representing Tonbridge at regional and national debating tournaments. The society generates genuine intellectual friction, creating space for girls to rehearse complex ideas in structured formats.
The International Society channels the school's global outlook, hosting visiting speakers, organizing cultural celebrations, and contextualizing curriculum within wider international contexts. Given the IB emphasis on international perspectives, this society reflects institutional values rather than tokenistic international awareness.
The Student Newspaper provides a platform for student journalism, reporting on school events and providing editorial space for student voice. This sustains media literacy and holds the school accountable to its communities.
Duke of Edinburgh's Award uptake reaches substantial levels, with Bronze, Silver, and Gold cohorts active across year groups. The expedition elements (hiking, camping, navigating) provide memorable learning beyond the classroom.
House competitions create inter-cohort identity and friendly rivalry. Debates, sports, academic quizzes, and social events distribute achievement across multiple domains, recognizing that excellence takes varied forms.
The school operates substantive educational visits, not brief day excursions. Trips to Iceland, Japan, and Malawi feature in the enrichment programme, enabling girls to encounter geographical and cultural contexts directly. These visits typically integrate curriculum, geography fieldwork in Iceland, development education in Malawi, rather than occurring as entertainment add-ons.
The International Baccalaureate curriculum explicitly requires intercultural awareness; these trips operationalize that curriculum philosophy.
Beyond content delivery, the school's pedagogical approach emphasizes inquiry-based learning and the development of independent research capabilities. Middle Years Programme structure (Years 7-9) introduces the International Baccalaureate thinking skills framework, preparing students for the formal IB Diploma in sixth form. Concepts like theory of knowledge (exploring epistemology and the nature of knowledge itself) appear in Year 9 classrooms, making philosophical inquiry routine rather than optional.
The Extended Essay requirement in IB sixth form (4,000-word independent research project) receives support across the curriculum, with subject teachers offering guidance on topic development, methodology, and argumentation. Library resources, research databases, and dedicated sixth form study spaces facilitate this work.
Assessment feedback is continuous. Rather than relying on summative grades, teachers employ developmental marking that identifies specific areas for improvement. Pupils receive target setting conversations with form tutors, linking academic development to pastoral support.
Specialist provision exists for pupils requiring additional support, with small group teaching available for those struggling with core concepts. Equally, extension work stretches the most able, ensuring that selectivity translates into appropriately pitched challenge across the attainment spectrum.

Entry at age 11 is through the Kent Test, the selective assessment used across Kent grammar schools. Girls must achieve an aggregate score of 332 with no single component below 108.
The oversubscription environment is significant: 829 applications competed for 180 places in recent years. Oversubscription criteria allocate places first to looked-after children and those with EHCP naming the school. Up to 135 places go to girls living within the priority catchment area (three designated council tax zones), allocated by highest test score with distance as a tiebreaker. A further 35 places remain available to girls from outside the priority area, again allocated by test score then distance.
The selective nature creates tutoring culture. Families actively prepare daughters for the Kent Test, and many engage private tutors. The school itself does not formally recommend tutoring, but the competitive environment makes it nearly universal in practice. Families considering application should budget for preparation support and recognize that entry is markedly competitive.
Sixth form entry (age 16) follows different criteria. The IB Diploma requires breadth, so entry typically requires strong grades across diverse GCSE subjects rather than specialization. School priorities sixth form entry, offering approximately 180 places across internal progression and external entry. Boys enter at this point, creating the co-educational sixth form.

School hours run 8:50 AM to 3:20 PM for pupils in Years 7-11. Sixth form follows a similar timetable but with greater flexibility around study periods and supervised independent learning time.
The school offers no wraparound care (breakfast clubs or after-school care), reflecting its secondary grammar status. Pupils are expected to manage independent travel home. Local bus routes serve Tonbridge, with the school accessible by car or coach from surrounding areas.
Parking on-site is limited, with priority given to staff. Parents are directed to public car parks or train station parking for visit days. The school sits on the edge of Tonbridge town centre, making pedestrian access feasible for local families.
Uniform is required for pupils in Years 7-11, creating visible cohort identity. Sixth formers follow a dress code (smart business attire) rather than formal uniform, symbolizing their transition toward independence.
Lunch facilities provide hot meals daily. The refectory opens to all pupils, with vegetarian options available and awareness of dietary requirements evident in menu planning.
Transport links are reasonable. Tonbridge railway station (served by South Eastern trains to London Bridge and other destinations) sits 0.5 miles from the school. Local bus services connect surrounding villages.
The house system forms the foundation of pastoral care. Each house has a dedicated team comprising a head of house, tutors, and administrative staff. Girls see their form tutor daily, creating continuity and enabling early identification of concerns.
Wellbeing provision includes counselling services, with trained counsellors available for individual sessions. The school explicitly prioritizes mental health literacy, ensuring pupils understand stress management and access support without stigma.
Safeguarding procedures are formalized and regularly reviewed. The school maintains a safeguarding committee and designated leads, ensuring that child protection responsibilities are taken seriously. Pupils are taught to recognize and report concerning behavior through PSHE curriculum (Personal, Social, Health, and Economic education).
Bullying policy is explicit: the school takes all reports seriously and investigates thoroughly. Peer support systems enable younger pupils to approach older students with concerns, creating multiple reporting pathways.
The school explicitly acknowledges diversity and inclusion. LGBTQ+ pupils receive support through student-led organizations and staff training on inclusivity. The curriculum incorporates diverse perspectives, with literature, history, and science units reflecting varied voices and experiences.
Selective entry intensity: The competitive admissions process means girls must prepare seriously for the Kent Test. This creates a culture of early academic pressure that begins in Year 5 for many families. Children who thrive on challenge and competition often flourish here; those who find early selection stressful may prefer comprehensive alternatives.
IB complexity: The transition to full IB Diploma programme in sixth form is substantial. Girls must maintain breadth across sciences, humanities, and languages; there is no opportunity to abandon mathematics or English at age 16. This intellectual breadth benefits some students profoundly but creates workload intensity that should be clearly understood before entry.
Catchment variation: Admissions heavily prioritize the inner catchment area, meaning families living outside that zone face substantially lower admission likelihood. Distance from the school becomes critical for those from outer priority areas. Families should verify current distance requirements with the school before assuming access.
Gender dynamics: The main school (Years 7-11) remains predominantly female, with boys entering only at sixth form. This creates distinct social dynamics and may be a consideration for families seeking early co-education.
Tonbridge Grammar School offers exceptional academic education within a selective, purposeful environment. The ranking in the top 2% of schools in England (FindMySchool data) reflects genuine teaching quality combined with selective intake. The commitment to International Baccalaureate education and the school's performance as the UK's highest-achieving IB state school demonstrates educational vision beyond simple examination success.
The breadth of extracurricular provision, from the Motet Choir to the STEAM Club, from debate to Duke of Edinburgh, suggests that the school takes seriously the development of rounded individuals, not merely examination-passing machines.
This school suits girls who are academically ambitious, intellectually curious, and resilient in competitive environments. Those living within the priority catchment and scoring highly on the Kent Test will find a genuinely supportive learning community. The challenge is primarily securing entry; once through the door, the educational experience is demonstrably strong.
Yes. The school holds Outstanding status under Ofsted inspection. It ranks in the top 2% of schools in England for GCSE and A-level/IB results (FindMySchool ranking). In 2024, 82% of GCSE grades achieved the top two bands (9-7), compared to 54% in England. At International Baccalaureate level (sixth form), 88% of entries achieved A*-B grades. The school was named State Secondary School of the Year and IB School of the Year by the Sunday Times in 2014.
The Kent Test is the selective entrance examination used by Kent grammar schools. It assesses English, Mathematics, and Reasoning through timed papers plus a creative writing task. To qualify for grammar school consideration, pupils must achieve an aggregate score of 332 with no single score below 108. Entry to Tonbridge Grammar is highly competitive: approximately 829 girls applied for 180 places in recent years (4.6:1 ratio). Passing the test does not guarantee entry; places are allocated by test score within designated catchment priority areas, with distance used as a tiebreaker.
The school does not formally recommend tutoring. However, given the competitive nature of the test and the selective environment, tutoring is nearly universal in practice. Families should budget for preparation support, either private tutors or structured courses, as self-study alone is rarely sufficient to compete effectively.
Tonbridge is unique as a rare state school in the UK to commit entirely to the International Baccalaureate Diploma for sixth form, replacing A-levels completely. It has been recognized as the highest-performing IB state school in the UK for multiple consecutive years. The school also emphasizes specialist provision in Mathematics and Computing, operates vibrant music and drama programmes (Motet Choir is particularly notable), and maintains strong international partnerships through the IB curriculum philosophy.
The school occupies a 14-acre campus with multiple teaching facilities: the original Victorian building (extensively refurbished), the Hands Building (2009), the IBarn sixth form study centre (2015), the Matthews Centre technology block, music wing (refurbished 2015), science laboratories, and the #OurBigOutdoors sports facility (opened 2018, £2 million investment). The swimming pool dates to 1963 and has undergone recent refurbishment. Drama facilities include two performance spaces. The library serves as a research centre with digital databases and dedicated sixth form study areas.
In the measured 2023-24 cohort (118 sixth form leavers), six students secured Oxford places and one secured a Cambridge place, representing a combined acceptance rate of approximately 5% among those applying. Beyond Oxbridge, 68% of sixth form leavers progressed to university, with particular strength in Russell Group institutions including Imperial College, Durham, Edinburgh, and Bristol.
