Practical guidance from the Leading Tuition team
Book a Free ConsultationBoth Tiffin Girls' School and Tiffin School are among the most academically selective state grammar schools in England, and for families in Kingston upon Thames and the surrounding boroughs, the choice between them is rarely straightforward. The honest answer is that neither school is objectively better — they are distinct institutions with different cultures, entry processes, and strengths. The right choice depends on your child's gender, personality, learning style, and how well they perform under the specific demands of each school's entrance examination.
Both schools are state-funded, selective grammar schools in the Royal Borough of Kingston upon Thames. Tiffin School is a boys' grammar school for Year 7 to Year 13, while Tiffin Girls' School is an all-girls grammar school covering the same year groups. Both are non-fee-paying and consistently rank among the top state schools in England by A-level and GCSE outcomes.
At GCSE, both schools follow a broad curriculum aligned with AQA, Edexcel, and OCR specifications depending on the subject. At A-level, students typically choose three or four subjects from a wide range, and both schools have strong records of Oxbridge and Russell Group university entry. In recent years, both schools have regularly placed students at Oxford, Cambridge, and medical schools — with students now sitting the UCAT as part of medicine applications rather than the now-abolished BMAT.
This is where the comparison becomes genuinely practical. The two schools run entirely separate entrance examinations, and the style and weighting of those tests differ in ways that matter for preparation.
Tiffin School (boys) uses a two-stage process. Stage one is a multiple-choice reasoning test taken by a large cohort. Those who pass are invited to stage two, which includes more demanding papers in mathematics and English. The maths paper in particular is known for requiring strong problem-solving ability beyond standard Key Stage 2 curriculum content.
Tiffin Girls' School also uses a two-stage process, but the balance between verbal reasoning, non-verbal reasoning, and written English differs. The school places notable emphasis on extended writing and comprehension at stage two, which rewards students who read widely and can express ideas clearly under timed conditions.
Both schools draw applicants from a wide geographical area — not just Kingston but also Richmond, Sutton, Merton, and parts of Surrey. Competition is intense, with hundreds of applicants for roughly 120 places at each school each year.
Beyond the entrance exam, the day-to-day experience at each school is shaped by its single-sex environment. Research on single-sex education in the UK is mixed, but many parents and students report that both schools foster a focused academic culture where students feel less self-conscious about being openly ambitious or asking questions in class.
Tiffin School has a well-established reputation for mathematics and science, with strong participation in national competitions such as the UK Mathematics Trust (UKMT) challenges and the British Physics Olympiad. The school also has active sports teams, a strong music programme, and a debating culture.
Tiffin Girls' School is similarly strong across STEM subjects but is also widely recognised for its humanities and arts provision. The school has a particularly active drama and music scene, and students frequently go on to study a broad range of subjects at university — not just sciences.
Both schools expect a high level of independent study from Year 7 onwards. Students who thrive tend to be self-motivated, curious, and comfortable with a fast pace of learning.
When families ask how to choose between the two schools, the following points are worth working through honestly:
Preparation for both schools typically begins in Year 5, with focused work intensifying in Year 6. The core areas to develop are verbal reasoning, non-verbal reasoning, mathematics (including topics beyond the standard Year 6 curriculum), and English comprehension and writing.
For Tiffin School, particular attention should be paid to problem-solving in maths — questions often require multi-step reasoning and familiarity with topics such as algebra, ratio, and number theory at a level above what most primary schools cover. Past papers are available and should form part of any structured preparation plan.
For Tiffin Girls', the extended writing component means that regular practice with timed essays and comprehension responses is essential. Reading a wide range of fiction and non-fiction throughout Year 5 and Year 6 builds the vocabulary and analytical thinking the exam rewards.
Many families work with a specialist tutor to identify gaps and build exam technique. Leading Tuition works with students preparing for both schools and tailors preparation to the specific demands of each exam rather than using a one-size-fits-all approach.
Both schools consistently achieve outstanding results. At GCSE, the vast majority of students at both schools achieve grade 7, 8, or 9 (equivalent to the old A and A* grades) across core subjects. At A-level, both schools regularly feature in national rankings for average point scores per student.
University destinations reflect the academic intensity of both schools. Oxbridge entry, medicine, law, and engineering are common outcomes, but students also go on to study arts, languages, and social sciences at leading universities. Neither school pushes students towards a narrow range of subjects — both encourage students to follow genuine interests at A-level.
Is Tiffin Girls' School harder to get into than Tiffin School?
Both schools are extremely competitive, with hundreds of applicants for around 120 places each year. The difficulty is comparable, though the style of the exam differs. Tiffin Girls' places greater weight on extended writing at stage two, while Tiffin School's stage two is more heavily weighted towards mathematics. Neither is straightforwardly harder — it depends on your child's individual strengths.
What area do Tiffin Girls' and Tiffin School take pupils from?
Both schools are open to applicants from across England, though in practice most successful applicants come from Kingston upon Thames, Richmond, Sutton, Merton, and parts of Surrey. There is no strict catchment area, but distance from the school can be a tiebreaker if two applicants score equally. Families outside the immediate area should check the latest admissions policies on each school's website.
When should my child start preparing for the Tiffin entrance exam?
Most families begin structured preparation in Year 5, which gives roughly 12 to 18 months before the exam in Year 6. Starting earlier than Year 5 is rarely necessary and can lead to burnout. The focus should be on building genuine understanding in maths and English rather than drilling past papers too early.
Do both schools offer sixth form places to external applicants?
Yes, both Tiffin Girls' School and Tiffin School accept external applicants into Year 12 (sixth form). Entry is competitive and based on predicted or achieved GCSE grades — typically requiring grade 7 or above in subjects to be studied at A-level, and strong overall GCSE profiles. This is a realistic route for students who did not join at Year 7.
Choosing between these two schools ultimately comes down to which environment will allow your child to flourish — academically, socially, and personally. Both offer an exceptional state education, and either would be a strong foundation for whatever comes next. Taking the time to visit, to understand the exam demands, and to listen to your child's own instincts will put you in the best position to make the right call.
