Has the 10 km rule changed?

What the school's own documents say, year by year.

Entry yearWhat the school says
Since the Priority Area was introducedPlaces have only been offered to boys living within 10 km of the school. It was previously called the Inner Priority Area. The FAQ does not give the year it began. Source
2025 entry onwardsUp to 10% of places for sport (5%) or music (5%) aptitude, with earlier registration deadlines. The 2027 policy reserves up to 18 places (9 sport, 9 music) for Priority Area boys at or above the 450th ranked Combined Score. Source
2026 entry to 2027 entryThe 10 km Priority Area, the 50% English and 50% maths Combined Score (maths from Stage One and Stage Two in the ratio 2:3), the 450th-rank threshold for priority groups and the 18 reserved aptitude places read the same in both determined policies. The registration deadline moved from noon on 3 September 2025 to noon on 2 September 2026. Source
2028 entryNo determined policy for 2028 entry was published when we checked. Do not assume the 2027 rules carry over. Source

The address that counts, and who checks it

  1. The address that counts is where your son permanently lives on 31 October 2026, the council application closing date. Your local authority asks for evidence of it. Source
  2. Kingston Schools Admissions verifies the address and measures the straight line with its own mapping system. The school cannot tell you the distance in advance, and its figure is the one used. Source
  3. Aptitude places need a Priority Area address. If the council later finds a different address outside 10 km, the school cancels the aptitude result. Source
  4. If you move after 31 October 2026, contact your local authority, not the school. Source

A result here is an estimate from your postcode's centre point. Only Kingston Schools Admissions' measurement from your home's address point decides.

The Tiffin School priority area, in plain English

What is the Tiffin School priority area?

Every boy who lives less than 10 km from Tiffin School, in a straight line, lives in the Priority Area. It is what most parents mean by the Tiffin Boys catchment area. There is no list of postcodes and no drawn boundary: the council measures each home.

Does living within 10 km get my son a place?

No. It decides the order, not the outcome. Boys who sat Stage Two are ranked by Combined Score, and Priority Area boys come before everyone else. For 2026 entry, 665 boys sat Stage Two and 186 places were offered on 1 March, every one to a Priority Area boy.

How is the 10 km measured?

Kingston Schools Admissions measures a straight line from the Ordnance Survey address point of your home to the Queen Elizabeth Road pedestrian gate. The school publishes its grid reference as 518588, 169434. This checker measures from the centre of your postcode, so it calls anything within 250 m of the line too close to call.

Can boys who live further than 10 km away apply?

Yes, but they are ranked after every Priority Area boy, and no place has gone to a boy outside the area since it was introduced in September 2019. The school asks families outside it to think carefully before registering.

Which address counts, and what if we move?

The address where your son lives permanently when you submit your council application, by the 31 October 2026 deadline for 2027 entry. Your council checks it and will ask for evidence. If you move after that date, speak to your council, not the school.

Is there a policy for 2028 entry yet?

Not yet. The current policy covers September 2027 entry, for boys born from 1 September 2015 to 31 August 2016, and says its next review is in spring 2027. Until then the 2027 rules are the best guide, and they can change.
