You've heard that Tiffin School in Kingston upon Thames is exceptional, you know the competition is fierce, and you're trying to work out where on earth to begin. What does the exam actually test? How early should preparation start? And how do you know if your son is genuinely on track, rather than just getting through practice papers? This guide answers those questions directly, based on what the Kingston Grammar Test actually demands — not a generic overview of the 11+ process.
Tiffin School uses the Kingston Grammar Test, which is shared with a small group of selective schools in the borough. The test is administered in two stages. The first stage is a standardised assessment sat by all registered candidates, typically in September of Year 6. It covers verbal reasoning, non-verbal reasoning, and mathematics. Children who score highly enough are then invited to a second stage, which includes a more demanding mathematics paper and an English paper assessing reading comprehension and written composition.
The mathematics sections test problem-solving and reasoning rather than rote recall. Questions often require children to work efficiently under time pressure, applying concepts such as fractions, ratio, algebra, and geometry in unfamiliar contexts. The verbal reasoning component tests vocabulary, word relationships, and logical language skills. Non-verbal reasoning assesses spatial and pattern-based thinking. The English writing task rewards clarity, structure, and genuine engagement with the prompt — not formulaic responses.
One preparation detail that many families overlook: the Kingston Grammar Test mathematics questions frequently present multi-step problems where the method is not immediately obvious. Children who have only practised straightforward computation often stall at these points. Practising problems that require two or three logical steps — and building the habit of showing working clearly — is far more valuable than drilling single-operation questions at speed.
Tiffin School consistently ranks among the highest-performing state schools in England. Its Sixth Form results, university destinations, and academic culture make it genuinely distinctive — not just selective by reputation, but selective in outcome. The school admits approximately 120 boys each year from a pool of around 2,000 applicants. That means roughly one in seventeen boys who sit the test will receive an offer. The children who succeed are not simply bright — they are well-prepared, confident under pressure, and able to perform consistently across every section of the test.
The catchment is also worth understanding. Because Tiffin is a state grammar school, there is no fee barrier, which means the applicant pool draws from a very wide area and includes many children who have received intensive preparation. Families should approach this process with clear eyes: the standard required is high, and preparation needs to reflect that honestly.
Key characteristics of successful Tiffin applicants typically include:
At Leading Tuition, we provide 1-to-1 specialist tutoring tailored specifically to the Kingston Grammar Test and the demands of Tiffin School's admissions process. That specificity matters. A tutor who understands the exact format, the typical difficulty curve of the second-stage mathematics paper, and the style of writing prompt used in the English section can target preparation far more precisely than a general 11+ programme.
We begin with a diagnostic assessment to identify where a child is genuinely strong and where gaps exist — because surface confidence can mask real weaknesses, particularly in mathematical reasoning and extended writing. From there, we build a structured programme that develops skills progressively, introduces timed practice at the right stage, and builds the kind of exam composure that only comes from repeated, well-supported practice.
We also work with parents throughout the process, providing honest progress updates and clear guidance on what realistic targets look like at each stage of preparation. Our aim is not to create anxiety but to replace uncertainty with a clear plan.
Preparing for Tiffin School is a significant undertaking, and it affects the whole household — not just the child sitting the exam. Parents often carry the weight of research, logistics, and emotional support simultaneously, while also trying to judge how much pressure is appropriate. Children, meanwhile, need to sustain motivation across a preparation period that can span twelve months or more.
The most effective preparation is consistent rather than intensive. Short, focused sessions several times a week tend to produce better results than weekend cramming, particularly for younger children who are also managing a full school timetable. Building in regular breaks, celebrating genuine progress, and keeping the process proportionate to your child's wellbeing are not soft considerations — they are practical ones. A child who arrives at the exam exhausted or anxious will not perform to their ability, however well they have prepared.
It also helps to keep perspective on the wider picture. Tiffin is an outstanding school, but it is one option among several excellent ones. Families who approach the process with a clear first choice and a genuine second choice tend to navigate it with less stress than those who have placed everything on a single outcome.
When should we start preparing for the Tiffin School 11+?
Most families begin structured preparation in Year 4 or early Year 5, with more focused exam-specific work in Year 5 and into the first term of Year 6. Starting earlier than Year 4 is rarely necessary and can lead to burnout. Starting later than January of Year 5 leaves limited time to address genuine gaps, particularly in mathematical reasoning and vocabulary. The right start point depends on your child's current level — a diagnostic assessment is the most reliable way to judge this.
How do we keep a child motivated over such a long preparation period?
Motivation is sustained by visible progress, not by pressure. Children respond well when they can see themselves improving on specific skills — getting faster at a type of problem, writing a stronger paragraph than they did a month ago. Breaking preparation into clear, achievable stages helps enormously. It also matters that preparation doesn't consume every weekend and holiday. Children who have time to pursue other interests throughout Year 5 and 6 tend to arrive at the exam in better shape than those for whom 11+ has become the only focus.
Are practice papers alone enough to prepare for the Kingston Grammar Test?
Practice papers are an essential part of preparation, but they are not sufficient on their own. A child who works through papers without understanding why they are making errors will repeat those errors under exam conditions. Effective preparation involves identifying the specific skills and concepts that need development, building those systematically, and then using timed papers to consolidate and build exam confidence. Papers without teaching tend to produce a plateau — scores improve initially and then stop.
How do we manage preparing for Tiffin alongside applications to other grammar schools?
Many families apply to two or three selective schools simultaneously, which is sensible. The Kingston Grammar Test has a specific format, so preparation should be anchored to that — but the underlying skills in mathematics, verbal reasoning, and English transfer well to other tests. The main risk of applying to multiple schools is spreading preparation too thinly across different formats. We recommend identifying your priority school, building preparation around that exam, and then familiarising your child with any format differences for secondary choices in the final weeks before those tests.
