Tiffin School Priority Area Guide 2026

Does Tiffin School Have a Catchment Area?

Unlike Queen Elizabeth's School Barnet, which has no catchment and uses distance only to break ties, Tiffin School does apply geography as part of its admissions process — but not through a borough list. The school's own term is Priority Area, and it is defined purely by straight-line distance, not local authority boundaries. Since the 10km Priority Area was introduced in September 2019, every place has gone to a boy living inside it.

Tiffin's Priority Area is any address within 10km in a straight line of the school gates, measured using computerised geographical mapping systems. Apart from a boy with an EHCP naming the school, every boy inside that radius is ranked ahead of every boy outside it, and within the Priority Area places go in Combined Score order (see below); there is no list of qualifying boroughs to check against.

How the 10km Priority Area Actually Works

Because the Priority Area is a radius, not a borough list, two families in the same borough — even the same street in some cases — can fall on different sides of the line depending on exactly how far their address is from the school gates. This is a meaningful difference from how many other London grammar schools define priority (Wilson's School, for example, has no priority area at all: it fills its 186 places in rank order of score after its looked-after, free-school-meal and aptitude places, and living in the London Borough of Sutton only decides between boys tied on the same rank), and it means Tiffin families should measure the straight-line distance from their own address rather than relying on borough membership as a shortcut.

We measured the straight-line distance from the grid reference the school publishes for itself (518588, 169434) to the centre of each surrounding postcode district. Every Kingston upon Thames district sits well inside 10km, and so do the main Richmond upon Thames districts, but much of Wandsworth is inside too, while Lambeth lies just beyond it (its nearest districts, SW12 and SW16, are about 11 to 12km away) and Southwark further still.

A postcode district spans a kilometre or more, so these figures only show where the line runs; the only way to know for certain is to measure your own address, not to assume based on borough.

How Does the Priority Area Affect Your Chances?

The practical effect of the Priority Area is significant. Tiffin's admissions policy states that since the 10km Priority Area was introduced in September 2019, places have only been offered to boys living within it, and its Patterns of Admissions confirms that for 2024, 2025 and 2026 entry no place went to a boy outside it. That reflects the volume of applicants inside the area: for September 2026 entry, 1,866 boys sat Stage One for 186 places, one offer for every 10.0 boys tested. Boys outside the Priority Area remain eligible, but apart from a boy with an EHCP naming the school, they rank only for places left after every Priority Area boy has been placed, and the up to 18 places reserved for sporting or musical aptitude are open only to Priority Area boys.

There is no fixed score threshold that differs neatly between "in-area" and "out-of-area" applicants, because Tiffin sets no pass mark in advance. Scores are standardised and age-weighted, and boys are ranked by a Combined Score — weighted 50% Stage Two English and 50% Maths (itself 40% Stage One, 60% Stage Two) — and the cut-off is simply the lowest Combined Score of any boy who is offered a place that year, which varies with the strength of that year's applicant pool.

What Happens If We Are on the Boundary?

Because the Priority Area is a 10km straight-line radius rather than a list of local authority areas, "the boundary" is not a fixed administrative line — it is a circle drawn on a map, and a family's address either falls inside it or outside it by however many hundred metres. There is no graduated priority for boys who live very close to the school within the radius; a boy 1km from the gates and a boy 9.9km from the gates are both simply "inside the Priority Area" for ranking purposes, and both are ranked on Combined Score against each other and every other Priority Area applicant. Distance comes back in only to break a tie: if boys are level on the score for the last place, it goes to the boy who lives nearest.

Families who are close to the 10km line should not rely on borough membership, postcode lookup tools, or neighbour anecdotes to judge their status, since none of these map directly onto a straight-line radius. The reliable approach is to measure the straight-line distance from your address to the school gates yourself (a mapping tool with a "measure distance" function will do this in seconds), and to treat anything within a few hundred metres of the line as uncertain. The definitive measurement is made by Kingston Schools Admissions, and Tiffin School says it has no access to that system and cannot tell families in advance whether they are inside or outside the Priority Area.

Applying From Outside the Priority Area

Apart from a boy with an EHCP naming the school, who is placed first wherever he lives, Tiffin's own oversubscription criteria rank boys outside the Priority Area after every Priority Area boy, so a place could in principle go to a boy beyond the 10km radius only if any were left once every Priority Area applicant had been placed; since September 2019, none has been. The school's admissions policy is blunt about it: "If you do not live in the Priority Area, you should consider very carefully if you should register your son to sit the tests and make an application for a place at Tiffin School on your Home Local Authority application form." Boys outside the area are also not invited to the sport and music aptitude assessments, and do not receive the 10% Stage One leeway given to looked-after and Pupil Premium boys inside it. Demand from inside the area is what fills the school: 1,866 boys tested at Stage One for 186 places for 2026 entry.

Families living outside the Priority Area who have their heart set on Tiffin should set their preparation goal at the strongest possible Combined Score across both stages, rather than any specific historical figure — see our complete guide to the Tiffin School 11+ Quest Assessments for the full two-stage test format and how the Combined Score is calculated.

The Priority Area and Other Grammar Schools

Because Tiffin's 10km Priority Area overlaps with several other grammar school catchments, many families apply to multiple schools simultaneously from within the same geographic zone. Common combinations include:

Tiffin + Wilson's School: Many families in Sutton and Merton apply to both Tiffin (the bespoke Quest Assessments two-stage test) and Wilson's School (the Sutton SET). The examinations are entirely separate — on different dates, but with a similar shape of multiple-choice English and maths first and written English and maths second, so much of the preparation overlaps. Both schools can realistically be targeted in the same Year 6.

For daughters, Tiffin Girls' + Nonsuch High School for Girls: For girls in Kingston, most of Merton, or the Worcester Park (KT4) side of Sutton, Tiffin Girls' School and Nonsuch are both strong options; most of Sutton (SM1 to SM3, SM5 and SM6) is outside the Tiffin Girls' Designated Area, where no place has gone since 2014, though it is worth noting they use genuinely different systems — Tiffin Girls' sets its own two-stage English and maths test with a distinct designated-area model (see our Tiffin Girls' Designated Area Guide), while Nonsuch uses the Sutton SET. Nonsuch also draws its boundary differently: Nonsuch High School's 5.25km catchment circle is only the fourth of five admissions priority tiers, so being inside it counts for less than families usually assume.

Tiffin + Kingston Grammar School: Kingston Grammar School is an independent (fee-paying) school in Kingston with a different admissions process, but some families apply to both for a grammar-and-independent strategy from the same geographic base.

How to Check Your Priority Area Status

The admissions policy defines the rule, and the policy for each year's entry is published well ahead of it: the one for September 2027 entry was adopted in February 2026. The measurement itself is made by Kingston Schools Admissions, from the address the local authority verifies to the school's Queen Elizabeth Road pedestrian gate, and those are the figures Tiffin uses. The school says it cannot tell you in advance whether your address is inside the line, so estimate the distance with a public mapping tool.

Do not rely on borough membership, postcode lookup tools, or previous years' assumptions — because the Priority Area is a radius rather than a fixed set of areas, small changes in address can move a family from one side of the line to the other. The same warning applies wherever a school measures a radius rather than listing boroughs, though the distances vary widely: King Edward VI Grammar School Chelmsford's 12.5-mile priority area governs 120 of its 150 places. Check the current year's policy as soon as it is published (Tiffin's policy for September 2027 entry was adopted in February 2026, in the spring of Year 5) and factor your Priority Area status into your preparation and application strategy early.

Transport Links and Practical Considerations for Tiffin School

One practical dimension that families sometimes overlook when assessing Tiffin School is the question of how their son will actually get there each day. This matters both for wellbeing and for whether the school is realistic as a daily commitment, particularly for boys coming from the outer edges of the Priority Area.

Tiffin School is located on Queen Elizabeth Road in Kingston upon Thames, a short walk from Kingston town centre. The school is well served by public transport. Kingston railway station is approximately a ten-minute walk from the school and connects directly to Waterloo (approximately 30 minutes), Wimbledon, Raynes Park, and Clapham Junction. Numerous bus routes serve Kingston town centre, including services from Richmond, Twickenham, Surbiton, New Malden, and Wimbledon. For boys in Richmond, Twickenham, and the surrounding areas, the bus or train journey is typically 20 to 35 minutes each way.

For boys coming from the further edges of the 10km Priority Area — Merton, parts of Sutton, or Hounslow — the journey can be 40 to 55 minutes each way on public transport. This is not unusual for grammar school commutes, but families should factor it in when considering the practical impact on homework time, sports and club commitments, and general energy levels across a long school week.

Plan the daily journey before you apply. There is no parking at the school, which is on a busy one-way system and a red route where no stopping is allowed, so families who drive need to use public car parks rather than the school gates. Families should trial the journey at peak times before committing to the application rather than relying on off-peak or weekend journey estimates.
