King's College School Wimbledon 13+ Preparation

King's College School Wimbledon is an independent school on Wimbledon Common that admits boys to Year 9 through its own 13+ tests and interview, not the ISEB Common Pre-Test used at many other independent schools. For September 2029 entry, boys sit King's own English, Maths A and Maths B papers on Saturday 5 December 2026, with registration closing Monday 2 November 2026. Leading Tuition builds preparation programmes matched to that exact format.

King's College School Wimbledon Sets Its Own 13+ Tests — It Does Not Use the ISEB Common Pre-Test

Search for preparation advice for this school and the first thing many families meet is the ISEB Common Pre-Test. One widely read tutoring guide states plainly that "King's College School Wimbledon now requires students to complete the ISEB Common Pretest", and dates that change to the COVID-19 pandemic. It is not what King's own admissions page says today, and building a preparation plan around the wrong exam wastes exactly the months a family cannot get back.

King's own words on its 13+ admissions page are unambiguous: entry is "via competitive tests and interviews which take place in December/January of year 6." No ISEB reference appears anywhere on that page. King's specimen papers are titled "English 11+ & 13+ pre-test specimen paper", "Maths A 11+ & 13+ pre-test specimen paper" and "Maths B 11+ & 13+ pre-test specimen paper" — King's own house term for its own bespoke papers, not the externally administered ISEB product used at schools that outsource their pre-testing to that consortium. A family preparing on ISEB-style adaptive digital tests is preparing on the wrong format for this particular school.

The confusion is understandable. Many London and Surrey independent schools genuinely have moved their 13+ intake onto the ISEB Common Pre-Test over the past decade, so treating "13+ means ISEB" as a safe default is a reasonable habit — it is simply wrong here. It is also not possible to apply for both the 11+ and 13+ entry points at King's in the same year: all candidates for both routes are assessed in Year 6, and offers for both are made in February of Year 6, so a family choosing this route commits to it rather than hedging across both.

What the King's 13+ Assessment Actually Involves

The written component sits across three King's-set papers: English, Maths A and Maths B. King's publishes specimen versions of all three for families to review ahead of the test. Reasoning is also assessed, but King's does not publish its own sample verbal reasoning paper — its admissions page tells families that "we do not supply sample verbal reasoning papers but these are readily available from booksellers", which confirms reasoning forms part of the assessment even though the practice material for it comes from commercial publishers rather than the school itself.

All of this happens in a single sitting: the 13+ entry tests for September 2029 entry are set for Saturday 5 December 2026, in the morning. Boys who clear the written stage are told by email whether they have been invited to interview, with invitations going out in January; the interviews themselves run over three days in mid-January, and results follow within a month of the written tests. There is no separate registration for individual papers and no option to sit only part of the assessment — a boy who registers by the November deadline sits the full set on the same December morning as every other 13+ candidate that year.

From the Year 6 Test to Year 9 Entry: What Happens in the Gap

This is the part almost no advice page for this school explains, and it matters more than the test itself: a boy who passes the Year 6 assessment does not start at King's the following September. He is offered a conditional place, results are emailed in February of Year 6, and he then spends two further school years — Years 7 and 8 — at his current prep or junior school before he arrives at King's for the fourth form. Almost three years pass between sitting the test and walking through the gates.

That conditional place is not automatic. King's confirms it "by means of two satisfactory head teacher's reports: the first by the end of the summer term in year 7; the second by the end of the spring term in year 8", and formally confirms the place for Year 9 entry "by the middle of May in year 8." In January of Year 7, families are asked to pay a deposit — "one half of a term's school fees (currently £5,970)" — to confirm King's as their first-choice school, due in the admissions calendar in early February 2028 for the 2029 intake. Boys holding a conditional place who want to be considered for an academic scholarship sit King's scholarship examinations in May 2029, shortly before a welcome day in June 2029 and the start of term in September 2029.

The practical consequence for preparation is that the exam is not the end of the process, only the first and highest-stakes step of it. A family that treats results day in February of Year 6 as the finish line can be caught out later by a head's report that falls short of King's expectations, or by missing the deposit deadline. Keeping a boy's academic performance and school reference strong across Years 7 and 8, not only in the run-up to December, is part of securing the place King's has conditionally offered.

Boys-Only at 13+ Until September 2035

King's College School Wimbledon currently admits boys only through its 13+ entry point. That is changing on a published timetable, not an open-ended one: King's states that "girls and boys will be admitted to year 9 (fourth form) of the senior school at 13+ from September 2035" as part of a wider move to full co-education across the school. Families researching 13+ entry today, for the cohort born between 1 September 2015 and 31 August 2016, are applying under the boys-only arrangement; the change affects intakes from 2035 onwards, not the current cycle.

Is There a Second Chance If a Boy Misses the Year 6 Assessment?

King's runs a distinct late-assessment route for boys who did not sit the main Year 6 test, sat it without receiving an offer, or were placed on the waiting list. Its own page describes the eligibility plainly: it is open to "pupils who did not sit the pre-test in year 6 or who sat the test but did not receive an offer, who have the full support of their head as a strong candidate to join King's in year 9", and separately to "all those who have been placed on the waiting list after the pre-test in year 6." The next round of this route runs in the autumn term of Year 8, for boys born between 1 September 2013 and 31 August 2014. It is a genuine second door into King's at 13+, not a formality, but it depends on a strong head's reference and is explicitly framed as a route for boys who have kept performing well since the missed or unsuccessful first attempt.

Scholarships at 13+

King's awards up to eight academic scholarships each year at 13+, though the exact number varies "according to the quality of the candidates" in any given cycle. Scholarships in Art, Drama, Music and Sport are also available. In every case, the school requires the boy to already hold a conditional place for Year 9 entry the following September before he can be considered for a scholarship — the award sits on top of a place already offered through the standard 13+ assessment, not as an alternative route into the school.

How Leading Tuition Prepares Boys for King's College School Wimbledon 13+

Our tutors build 13+ preparation around King's own format, not a generic ISEB-style course: written English, Maths A and Maths B papers set by the school, plus the reasoning component King's assesses but does not itself publish practice material for. Where a family's son also has a Consortium or ISEB-format school on his shortlist, we say so plainly and prepare the two formats separately, because treating them as interchangeable is precisely the mistake this page exists to correct.

A programme typically starts in Year 5, giving time to work through comprehension, extended writing, both King's maths papers and reasoning practice well before the Saturday 5 December test date, then shifts to focused interview preparation once interview invitations are due in January. Tutors also help families plan for the two years between a conditional offer and Year 9 entry — the head's-report checkpoints at the end of Year 7 and Year 8 are as relevant to a family's planning as the exam itself, and our tutors keep an eye on both.

Families who are also weighing King's 11+ entry point, which runs on a different timetable and test format, can read our separate King's College School Wimbledon 11+ preparation guide. For a wider view of how the externally administered ISEB Common Pre-Test itself is structured, at the schools that do use it, our ISEB Common Pre-Test preparation page sets out the format King's specifically does not follow. Families still weighing up how Common Entrance and pre-test routes generally differ at 13+ may also find our 13+ Common Entrance exam guide useful background before narrowing in on King's own format.
