Tiffin Girls' Designated Area — 2026 Admissions Guide

Tiffin Girls' School in Kingston upon Thames is one of England's most sought-after selective grammar schools, and understanding its designated area is the first practical step for any family considering an application for September 2026 entry. In short, Tiffin Girls' does not use a traditional catchment area based on home address. Instead, it operates a designated area — a defined geographical zone — within which a girl must live to be eligible to sit the school's entrance examination. If your daughter does not live within that zone, she cannot apply, regardless of academic ability.

What Is the Tiffin Girls' Designated Area?

The designated area for Tiffin Girls' School covers a broad stretch of south-west London and Surrey. For recent admissions cycles, it has included the London Boroughs of Kingston upon Thames, Richmond upon Thames, Merton, Sutton, Croydon, Lambeth, Wandsworth, and Bromley, as well as parts of Surrey including Elmbridge, Epsom and Ewell, Mole Valley, Reigate and Banstead, and Tandridge districts.

It is essential to check the school's official admissions policy for the 2025–26 academic year (governing September 2026 entry) directly on the Tiffin Girls' School website or via the Royal Borough of Kingston upon Thames, as boundaries can be reviewed annually. The policy document will specify the exact postcode districts included. Do not rely on information from previous years without verifying it against the current published policy.

How Residency Is Defined and Verified

Living within the designated area is not simply a matter of having a local postcode. The school applies strict residency rules to prevent families from using temporary or fraudulent addresses. Key points include:

• Your daughter must be permanently resident at the address you declare at the time of application — typically the closing date for registration, which usually falls in late June or early July of the year before entry.
• The address used must be the child's sole or main home. Where parents live separately, the address of the parent with whom the child spends the majority of school nights is used.
• The school may request supporting documentation such as a council tax bill, utility bill, or GP registration letter to verify the address.
• Moving into the area after the registration deadline will not qualify a child for that admissions round.
• If a fraudulent address is discovered at any point — even after a place has been offered — the offer can be withdrawn.

Families who are genuinely in the process of moving should contact the school's admissions team directly to understand how their circumstances will be assessed.

The Entrance Examination: What Year 6 Girls Need to Know

Tiffin Girls' School selects entirely on academic ability. Girls currently in Year 5 (during the 2024–25 academic year) who are aiming for September 2026 entry will sit the entrance examination in autumn 2025, typically in September or October.

The test is set and marked by the school itself — it does not use GL Assessment or CEM papers, which are common at other grammar schools. The examination assesses English and mathematics, and in recent years has included a writing component alongside comprehension and reasoning tasks. There is no verbal or non-verbal reasoning paper in the style used by many other selective schools, which means generic 11-plus preparation materials alone are unlikely to be sufficient.

Results are used to rank all eligible candidates. A place is only offered if a girl both scores highly enough and lives within the designated area. There is no separate waiting list tier for out-of-area applicants — the area boundary is a hard eligibility requirement, not a tiebreaker.

How Many Places Are Available and How Competitive Is It?

Tiffin Girls' School admits 120 girls into Year 7 each September. Given the size of the designated area — which covers a population of well over a million people — competition is intense. In recent years, several hundred girls have sat the examination for those 120 places, making it one of the most competitive state grammar schools in England.

The school is a state-funded selective grammar school, meaning there are no fees. It is part of the state sector and follows the national curriculum framework, with students typically sitting GCSEs (usually nine to ten subjects) and then A-levels in the sixth form. The school is not affiliated with a specific exam board for all subjects, but commonly uses AQA, Edexcel, and OCR depending on the subject.

Because the school is non-fee-paying and highly regarded — consistently among the top-performing schools nationally by GCSE and A-level results — demand significantly outstrips supply every year.

Applying Through Kingston's Secondary Transfer Process

Even if your daughter passes the Tiffin Girls' entrance examination and receives a qualifying score, you must still name the school on your Local Authority (LA) Common Application Form (CAF). In Kingston upon Thames, this is submitted through the Royal Borough of Kingston upon Thames admissions portal, with the national secondary school application deadline of 31 October each year.

Tiffin Girls' is a foundation school that manages its own admissions, but places are still coordinated through the LA on National Offer Day — 1 March (or the next working day). Families living outside Kingston but within the designated area apply through their own LA's CAF and name Tiffin Girls' as one of their preferences.

It is worth noting that the Tiffin Girls' registration process (to sit the exam) has its own earlier deadline, separate from the LA application. Missing the exam registration deadline means your daughter cannot sit the test, regardless of where you live.

Common Misconceptions About the Designated Area

Several misunderstandings circulate among families new to the process. The most important ones to correct are:

Misconception 1: "The designated area is the same as a catchment area." It is not. A catchment area typically determines priority for oversubscribed non-selective schools based on proximity. The Tiffin Girls' designated area is purely an eligibility boundary — it determines who can sit the exam, not who gets priority within it.

Misconception 2: "Living closer to the school gives you an advantage." Distance from the school plays no role in the offer process. All eligible girls who sit the exam are ranked solely by their test score.

Misconception 3: "The designated area changes every year." The boundaries have been relatively stable, but the school does review its admissions policy annually. Always read the current year's published policy rather than relying on secondhand accounts.

Frequently Asked Questions

Does the Tiffin Girls' designated area change for 2026 admissions?

The designated area has remained broadly consistent in recent years, covering several London boroughs and Surrey districts. However, the school reviews its admissions policy annually, so families should read the official 2025–26 admissions policy — published on the school's website — before assuming the boundaries are identical to previous years.

What happens if we move into the designated area after the registration deadline?

If you move into the designated area after the exam registration deadline has passed, your daughter will not be eligible to sit the entrance examination for that admissions round. The residency requirement applies at the point of registration, not at the point of the exam or the LA application deadline.

Can my daughter apply to Tiffin Girls' if we live in Surrey rather than a London borough?

Yes. Several Surrey districts — including Elmbridge, Epsom and Ewell, and Mole Valley — have historically been included within the designated area. Families in these areas apply through Surrey County Council's CAF rather than Kingston's, but the process and deadlines are otherwise the same.

Is Tiffin Girls' School the same as Tiffin School?

No. Tiffin Girls' School and Tiffin School are two separate grammar schools located close to each other in Kingston upon Thames. Tiffin School is a boys' grammar school. Each has its own admissions policy, designated area, and entrance examination. Families with both sons and daughters need to check both schools' policies separately.

Understanding the designated area is genuinely the starting point for any Tiffin Girls' application — without confirmed eligibility, no amount of preparation matters. Once you have confirmed your address falls within the boundary, the focus can shift entirely to helping your daughter prepare thoroughly for an examination that rewards strong literacy, mathematical reasoning, and clear written expression. Leading Tuition works with families across south-west London and Surrey on exactly this kind of focused, exam-specific preparation. If you are at the early planning stage, the most useful next step is simply to read the school's current admissions policy in full and note every deadline in your calendar.
