Tiffin Girls' vs Tiffin School — How to Choose

Both Tiffin Girls' School and Tiffin School are among the most academically selective state grammar schools in England: for 2026 entry, 1,866 boys sat Tiffin School's Stage One for 186 places, and 1,468 girls sat the Tiffin Girls' Stage One for 180. 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. For most families the school is decided by the child: Tiffin School admits boys into Year 7 and Tiffin Girls' admits girls. The real comparisons come for families with a son and a daughter, who face two different tests and two different area rules, and for girls at 16, when Tiffin School's Sixth Form is open to them as well.

The Basics: What Kind of Schools Are They?

Both schools are state-funded, selective grammar schools in the Royal Borough of Kingston upon Thames. Tiffin School admits boys into Year 7 and girls as well as boys into its Sixth Form, while Tiffin Girls' School is an all-girls grammar school from Year 7 to Year 13. Both are non-fee-paying and heavily oversubscribed: for 2026 entry, 1,866 boys sat Tiffin School's Stage One and 1,468 girls sat Tiffin Girls'.

At GCSE, Tiffin Girls' options booklet lists AQA, Edexcel, OCR and Eduqas specifications, depending on the subject. At A-level, students at both schools choose from a wide range of subjects. 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.

The Entrance Examination: Key Differences

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 in English and maths only, with tests set each year in partnership with Quest. Stage One is computer-marked: the English paper is multiple choice and maths answers are multiple choice or numerical. The boys invited back sit handwritten English and maths papers at Stage Two. The school says its tests need no knowledge beyond the Year 5 National Curriculum, but they include questions in unfamiliar formats.

Tiffin Girls' School also uses a two-stage process in English and maths only, with a computer-marked Stage One and Stage Two papers the school says it sets and marks itself; neither school sets a verbal or non-verbal reasoning paper. The difference is in the weighting: the Tiffin Girls' Combined Mark is 60% English, against 50% at Tiffin School, and Stage One counts for 10% of the final mark at Tiffin Girls' against 20% at Tiffin School (our arithmetic from each school's published weighting). Tiffin Girls' says its Stage Two English paper includes a reading comprehension task and a creative writing task. Tiffin School says some of its English questions need longer written answers, and its illustrative questions include a story-writing task, though it warns that the papers change significantly from year to year. Both reward students who read widely and can express ideas clearly under timed conditions.

Both schools draw applicants from a wide area around Kingston, and competition is intense. The schools' own published figures set the two side by side:

Geography matters as much as the score. Apart from a few priority groups, such as children with an EHCP naming the school, both schools rank applicants living inside their area ahead of everyone else, and neither has offered a place outside it in the years it reports, but the two areas are drawn differently: a 10km circle around Tiffin School, and a fixed list of postcode districts for Tiffin Girls'. A family can be inside one and outside the other, so check both.

Academic Culture and School Environment

Beyond the entrance exam, the day-to-day experience at each school is shaped by its single-sex environment in Years 7 to 11 (Tiffin School's Sixth Form also admits girls). 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's leavers' destinations page reports over 30 students a year going on to Oxford and Cambridge. The school also has active sports teams, a strong music programme, and a debating culture.

Tiffin Girls' School offers a broad curriculum across the sciences, humanities and arts, and the school has an 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.

How to Decide: A Practical Framework

When families ask how to choose between the two schools, the following points are worth working through honestly:

• Gender: This is the most obvious factor. Tiffin School admits boys only; Tiffin Girls' admits girls only. There is no co-educational option between the two.
• Exam strengths: The two tests draw on the same core skills in English and maths, but the papers and the weighting differ: Tiffin School splits its Combined Score equally between English and maths, while Tiffin Girls' gives English 60%. For a family preparing a son and a daughter, that means the same core preparation with a little more emphasis on writing for Tiffin Girls'.
• School visits: Both schools hold open events for families of prospective Year 7 students; Tiffin School's Year 7 Open Evening for September 2027 entry was on 30 June 2026, before registration closed. Attending these is genuinely useful — the atmosphere, the students you meet, and the questions teachers answer will tell you more than any league table.
• Geography and commute: Both schools are located in Kingston upon Thames, and where you live can decide the outcome, not just break a tie: Tiffin School has offered no place outside its 10km Priority Area since it was introduced in September 2019, and Tiffin Girls' none outside its Designated Area since September 2014. Check your address against both before registering.
• Your child's preference: At age 10 or 11, children often have a stronger instinct about school environments than parents expect. A child who is enthusiastic about a school will generally prepare for its entrance exam with more motivation.

Preparing for the Entrance Exams

Preparation for both schools typically begins in Year 5, with focused work intensifying in Year 6. The core areas to develop are English comprehension and writing and mathematics; neither school tests verbal or non-verbal reasoning, and both say their tests assume only the Year 5 National Curriculum, with some questions in unfamiliar formats.

For Tiffin School, particular attention should be paid to problem-solving in maths and to the move from multiple-choice answers at Stage One to handwritten answers at Stage Two. Neither school publishes past papers; Tiffin School publishes illustrative questions for both stages instead, and both warn that their papers change every year.

For both schools, and especially Tiffin Girls' with its 60% English weighting, the written Stage Two English paper means that regular practice with timed writing 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.

Results and Destinations

Both schools consistently achieve outstanding results. Tiffin School described its 2026 GCSE results as its best ever and its 2026 A-levels as its highest ever percentage of A* grades, and Ofsted's January 2026 inspection of Tiffin Girls' found that pupils' achievement is superb.

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.

Frequently Asked Questions

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.
