Charterhouse 13+ Preparation

Charterhouse is a co-educational independent boarding and day school in Godalming, Surrey, educating pupils from age 13 to 18. Entry at 13+ follows one of three registration pathways — Year 6, Year 7 or Year 8 — each with its own deadline, and for 2026 the Year 6 and Year 7 pathways both close on 30 September 2026. Charterhouse describes itself as academically selective, admitting by competitive assessment, interview and school reference.

The Charterhouse Entrance Process — A Step-by-Step Guide

Charterhouse recommends applying through whichever year group a child is in now; the registration deadline and the resulting entry date both depend on the pathway used, as the table below shows. All three UK pathways follow a similar sequence: registration, an assessment (the ISEB Common Pre-Test for the Year 6 and Year 7 pathways, or a digital test for the Year 8 pathway), an Interview and Activities Assessment at Charterhouse, and an offer communicated within the same admissions year.

Registration costs £420.00 (inclusive of VAT) and is non-refundable under any pathway. Once an offer is made, Charterhouse asks families on the Year 6 and Year 7 pathways to accept it and pay a deposit within 8 weeks, and families on the Year 8 pathway to do so as soon as possible after the offer, noting that competition for places is high. The place itself is not confirmed at the point of offer: Charterhouse's own admissions pages state that all offers are conditional on a positive reference for performance and behaviour from the child's current school, sought as the child moves through Year 8 (or, for Year 8-pathway applicants, during that same year) — which is why consistent work across the years in between matters more than performance on a single day.

The ISEB Common Pre-Test — What It Is and Why It Matters

The ISEB Common Pre-Test is a computer-adaptive online assessment used by many senior independent schools, including Charterhouse, as part of admissions. Charterhouse's own pathway pages have all registered candidates sit the Pre-Test in the Autumn Term of Year 6 (Year 6 pathway) or Year 7 (Year 7 pathway), taken online at the candidate's current school and reviewed alongside a school reference.

The test covers four areas: English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning. Results are age-standardised, so a pupil tested earlier in the window is not disadvantaged against one tested later; ISEB's own Pre-Tests Framework describes the standardisation scale as averaging 100 across the independent-school applicant sample, and does not publish a specific pass mark for any individual school.

Because the test is adaptive, it adjusts in difficulty based on each answer given. This means that hesitation, guessing or running out of time on early questions can suppress a score significantly. Familiarity with the format matters as much as underlying ability. Pupils who have practised verbal and non-verbal reasoning in particular — areas not always covered systematically in prep school — tend to perform more consistently under timed conditions.

One concrete preparation tip: begin verbal reasoning practice at least six months before the test date, working through question types systematically rather than doing random mixed papers. Many pupils lose marks not because they lack the reasoning ability but because they encounter an unfamiliar question type mid-test and lose confidence. Knowing what to expect removes that risk entirely.

Common Entrance and School Papers — What Is Actually Tested

Charterhouse's own published 13+ process centres on the ISEB Common Pre-Test and an Interview and Activities Assessment at Charterhouse — not, for most candidates, a published Common Entrance mark threshold. The Interview and Activities Assessment mixes group activities, an interview and a written assessment; Charterhouse describes the written element as a piece of creative writing, used to get to know each prospective pupil beyond a single test score.

Common Entrance (CE) itself is coordinated by ISEB, whose own description is that its CE assessments are set by highly-experienced teachers from some of the UK's leading schools. Where a candidate's current prep school is CE-registered, Common Entrance at 13+ still runs to ISEB's own timetable of three sessions a year (November, January and May/June), with three compulsory papers — English, Mathematics and Science — plus optional papers from geography, history, classics, modern foreign languages, and theology, philosophy and religion. Charterhouse's own 13+ Scholarship papers are explicitly based on the Common Entrance syllabus, so CE content stays relevant even where it is not a separate hurdle for standard entry.

For families whose child is not at a CE-registered school, this distinction matters: Charterhouse's standard Year 6, Year 7 and Year 8 pathways do not name Common Entrance as a requirement anywhere in the school's own description of them. What Charterhouse's own site does say is that offers are conditional on a positive reference for both performance and behaviour from the current school — so the Pre-Test (or digital test), the Interview and Activities Assessment, and ongoing school performance carry the weight, rather than a single externally-set exam.

Preparation still needs to be broad. A pupil who is strong in one area but has allowed another — a subject at their current school, or one of the Pre-Test's four areas — to slip can find that this affects the overall picture Charterhouse builds up over Years 6 to 8, since reference, assessment and (where applicable) Common Entrance results are all considered together rather than in isolation.

Amazing tutors!

We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.

Where Pupils Most Often Lose Marks

In Mathematics, the most common issue is not a lack of understanding but a lack of method. CE maths papers reward clear working, and pupils who arrive at correct answers without showing their steps can lose marks that should have been straightforward. Algebra, fractions and problem-solving questions that require multi-step reasoning are the areas where preparation time pays off most directly.

In English, comprehension answers that are too brief or too vague are the most frequent cause of underperformance. Pupils need to practise quoting from the text, structuring their responses and demonstrating inference rather than just surface reading. Composition marks are often left on the table by pupils who write fluently but do not plan — a structured approach to timed writing makes a measurable difference.

In Verbal Reasoning, speed is the issue. The question types themselves are learnable, but pupils who have not practised under timed conditions often find that they know how to answer a question but cannot do so quickly enough. Regular, timed practice from Year 5 onwards builds the automaticity that the pre-test rewards.

For a closer look at how the 13+ English paper has changed for 2027 entry — relevant whether a child is preparing for the ISEB Pre-Test's English component or a CE-registered school's own Common Entrance English paper — see our English guide for 13+ entry.

Working With Leading Tuition on 13+ Preparation

Leading Tuition provides specialist 1-to-1 tutoring for 13+ preparation, working with pupils from Year 5 through to Year 8. Our tutors are experienced with both the ISEB Common Pre-Test and the Common Entrance subjects, and we tailor programmes to each pupil's current level, timeline and target school. For Charterhouse candidates specifically, we focus on building Pre-Test and interview performance early, then maintaining subject knowledge through Years 7 and 8 so that a pupil's ongoing school reference and, where relevant, Common Entrance results reflect what they are genuinely capable of.

We work with families across Surrey and nationally via online tutoring, and we are familiar with the expectations of schools in the Charterhouse bracket. Early engagement — ideally in Year 5 or the start of Year 6 — gives us the most time to build the foundations that make the difference at Pre-Test, interview and, where applicable, Common Entrance stage.

For the September 2027 entry cohort, Charterhouse's Co-Curricular Scholarship applications close on Friday 11 December 2026, with portfolios or videos due by Friday 8 January 2027; the Foundation (Academic) Scholarship application deadline is Friday 19 March 2027. Scholarships are offered across Academic, Art & Textiles, Performing Arts, Dance, Drama, Design Engineering, and Music and Sport, and can be held alongside a means-tested bursary.

Charterhouse's Year 9 Entrance Bursaries are academically competitive and means-tested; they are awarded following the ISEB Common Pre-Test and the Interview and Activity Afternoons, and the school states that awards can cover up to 100% of school fees depending on need.

Preparation rewards consistency rather than a late push. Families typically register in Year 5 or 6, and under the Year 6 pathway the resulting entry date can be roughly three years later — so a pupil's Pre-Test performance, their Interview and Activities Assessment result, and their reference through to Year 8 all sit within the same admissions picture. Leading Tuition works with Charterhouse candidates across each of these stages: Pre-Test coaching in Years 5 and 6, interview readiness, and — for CE-registered candidates — subject-specific Common Entrance work through Years 7 and 8.
