Real admissions data on which independent schools welcome state-school applicants at 13+ — and how to prepare
Book a Free ConsultationYes, a child at a state primary or state secondary school can apply for 13+ entry to an independent school for September 2027 — and at several leading schools, state-school pupils already make up a meaningful share of the intake. Wellington College's own admissions page reports that 16% of its Year 9 joiners come from state, grammar and 11-18 day schools; King's School Canterbury runs a dedicated non-prep-school entrance route that welcomes around 150 new pupils a year across all pathways; and Canford School states plainly that "while many come from independent Prep Schools, we also welcome pupils from a wide range of other educational backgrounds." The barrier most parents assume — that Common Entrance and the ISEB Common Pre-Test are built exclusively around a prep-school curriculum — is smaller in practice than it looks, provided families understand which route applies to them and register on time.
Yes. Independent schools that admit at 13+ (Year 9) draw their intake from a wider pool than many parents expect. Most schools' own admissions pages describe candidates coming from "a range of UK independent schools... as well as from state schools," in the words of King's School Canterbury, and Wellington College's own published figures put state, grammar and 11-18 day-school joiners at 16% of the Year 9 cohort — a further 11% arrive from international schools. Together, well over a quarter of a typical 13+ cohort at these schools has not come through the traditional prep-school-to-Common-Entrance pipeline.
What differs for state-school families is not eligibility but process. Prep-school pupils are usually prepared for the ISEB Common Pre-Test and Common Entrance as part of their normal Year 6 to Year 8 schooling, sitting practice papers and mock assessments set by their own teachers. A child at a state school will not receive this in-school preparation, which is precisely why some schools — King's Canterbury and Magdalen College School among them — run an entirely separate, non-prep-school application route with its own exam format and timetable, rather than expecting state-school candidates to sit an unfamiliar Common Entrance paper cold.
The table below sets out six schools with 13+ (Year 9) entry that either publish state-school intake data, run a dedicated non-prep-school application route, or make an explicit inclusive statement on their own admissions pages — verified directly from each school's official site during 2026.
| School | State-school pathway | 2026/27 key detail |
|---|---|---|
| Wellington College | 16% of Year 9 joiners from state, grammar and 11-18 day schools (11% international) | Registration closes 30 June 2026; ISEB test Oct/Nov 2026; offers March 2027, conditional only on a satisfactory Year 8 report |
| King's School Canterbury | Dedicated "Non-Prep School & International" route sitting King's own Entrance Exams (KEE) instead of the ISEB pre-test | ~150 pupils join at Year 9 annually; registration deadline 4 September 2026 |
| Magdalen College School | Explicit Year 9 route for candidates "currently in Year 8 at a state school" (separate from the prep-school pre-test route) | Registration closes 31 Oct 2026; exam 16 Jan 2027; interviews 26-27 Jan 2027; results 4 Feb 2027; fee £180 (UK) |
| Canford School | States directly: "we also welcome pupils from a wide range of other educational backgrounds" | Approx. 50 pupils join annually; multi-stage registration windows from Year 5 assessments onward |
| Cranleigh School | Applicants "from schools that do not offer the ISEB test" can sit it at Cranleigh Prep School | ISEB test Oct-mid-Nov 2026; assessment day Jan 2027; most offers made in the Lent term of Year 6 |
| Sevenoaks School | No school-type restriction; assessment weighted toward merit — a written test plus a 40-minute group discussion | "Later decision" ISEB window 1 Sept-27 Nov 2026; second-stage assessment 13 April 2027; results mid-May 2027 |
These are not the only 13+ schools open to state-school applicants — they are simply the six where Leading Tuition has been able to verify explicit, published policy or data directly from the school's own 2026/27 admissions pages. Families targeting a different school should check that school's admissions office directly, as policies and published intake data vary and change year to year.
The ISEB Common Pre-Test is the assessment used by the majority of 13+ independent schools as the first stage of admission, and it is designed to be sat by any Year 6 child regardless of their current school. It consists of four adaptive, multiple-choice papers — English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning — taking 2 hours 15 minutes in total, and results are age-standardised so that a child's birth month does not disadvantage them. Testing runs from the autumn term through to the spring term of Year 6, and — critically for state-school families — registration is handled directly by parents through ISEB's own Guardian Portal, not arranged by the child's school.
This matters because it means a state-school parent does not need their child's headteacher to "opt in" to the ISEB system to register. What can vary is where the test is physically sat: many schools expect candidates to sit it at their current school if that school is an ISEB-registered centre, but where it is not, target schools frequently offer an alternative. Cranleigh School, for example, states explicitly that candidates from schools that do not offer the ISEB test can sit it at Cranleigh Prep School by arrangement with the admissions team. Magdalen College School and Sevenoaks School publish similar detail on their own admissions pages. Parents should always confirm the nearest approved test centre with the target school directly rather than assuming their child cannot sit the test at all.
Preparing for 13+ Entry Without a Prep School?
Leading Tuition specialises in exactly this gap — building the Verbal Reasoning, Non-Verbal Reasoning, Maths and English skills that prep-school pupils receive as part of their normal timetable, from scratch, for children whose current school does not teach to the ISEB Common Pre-Test or Common Entrance.

The table below sets out the key 2026/27-cycle dates gathered directly from each school's own admissions pages.
| Milestone | Date / window | School |
|---|---|---|
| Wellington registration closes | 12 noon, 30 June 2026 | Wellington College |
| King's Canterbury registration closes | 4 September 2026 | King's School Canterbury |
| Sevenoaks ISEB / later-decision window | 1 September – 27 November 2026 | Sevenoaks School |
| Standard ISEB Common Pre-Test window | October–November 2026 (varies by school) | Wellington, Cranleigh & others |
| Magdalen College School registration closes | 31 October 2026 | Magdalen College School |
| Magdalen College School entrance exam | 16 January 2027 | Magdalen College School |
| Wellington offers issued | March 2027 | Wellington College |
| Magdalen College School acceptance deadline | 1 March 2027 | Magdalen College School |
| Sevenoaks results issued | Mid-May 2027 | Sevenoaks School |
The spread of dates matters for state-school families in particular: because a state-school child will not necessarily be told about a target school's registration window by their own school, families need to track these deadlines themselves, well before the Year 6 or Year 8 autumn term begins. Missing a registration date is one of the most common — and most avoidable — reasons a capable child never sits the assessment at all.
The single biggest practical difference is preparation, not eligibility. A prep-school pupil sits mock ISEB pre-tests, practice Common Entrance papers and interview-style discussions as a routine part of their Year 6 to Year 8 schooling — usually without their parents needing to organise anything beyond signing a form. A state-school pupil's teachers are focused on the national curriculum and, in Year 6, on SATs, not on ISEB reasoning papers or Common Entrance set texts, and a state secondary school in Years 7-8 has no reason to prepare a pupil for an independent-school entrance exam its own leavers will never sit.
This is exactly why several schools build a genuinely separate assessment route rather than a "sit the same paper, hope for the best" approach. King's School Canterbury's Non-Prep School & International route uses its own King's Entrance Exams (KEE) rather than the ISEB pre-test, administered flexibly at King's itself, the candidate's current school, through an education agency, or at a British Council office — recognising that state-school pupils are less likely to have an existing relationship with an ISEB-registered test centre. Magdalen College School goes further still, running its non-prep-school pathway a full two years later, in Year 8 rather than Year 6, with its own written papers (Maths, Non-Verbal and Verbal Reasoning, a Creative Writing paper, and an English paper with problem-solving) rather than expecting a state-school pupil to have already completed Common Entrance coursework designed around a prep-school syllabus.
What state-school families should not assume is that a lack of prep-school preparation shows up as a lower offer rate purely because of school type. Wellington College's selection process explicitly looks for candidates who show "real engagement, determination, and a sense of joy in learning" rather than polish acquired through years of exam familiarity, and its offers are conditional only on a satisfactory Year 8 report from the child's current school — whichever school that is — not on the type of school a child previously attended.
Because the preparation that prep-school pupils receive as a matter of course simply is not built into most state-school curricula, families applying from a state school need a structured external plan that starts earlier and covers more ground independently. The following timeline reflects the approach Leading Tuition recommends for the 2026/27 cycle.
Year 5 (the year before the main assessment window): Register early with any target school that has a Year 5 deadline — Wellington's window opens well before the June 2026 close, and Canford's Year 6-assessment registration closes at the end of July in Year 5. Begin building core reasoning skills: verbal reasoning through wide reading and vocabulary work, non-verbal reasoning through pattern and spatial puzzle books, and maths fluency beyond the pace of the national curriculum. At this stage the goal is exposure and confidence, not timed practice.
Year 6, September onward: Start structured, timed practice for the ISEB Common Pre-Test format specifically — the adaptive, multiple-choice structure across English, Maths, Verbal Reasoning and Non-Verbal Reasoning is unlike anything most state-school pupils will have encountered in class. Confirm with each target school exactly where and when your child will sit the test if their own school is not an ISEB centre, following Cranleigh's model of arranging an approved alternative venue. Track registration deadlines for every school on the shortlist — they range from late June through early September 2026 in this cycle and do not align with each other.
Year 6, into Year 7 for later-decision or non-prep routes: Where a target school runs a later or separate non-prep pathway — Sevenoaks' later-decision window runs to 27 November 2026, and King's Canterbury's KEE route sits outside the standard ISEB timetable entirely — prepare specifically for that school's own format rather than assuming ISEB pre-test practice transfers directly. Sevenoaks weights its second stage toward a 40-minute group discussion, which rewards a different kind of preparation (articulate, collaborative discussion) than a written paper alone.
Year 8 (for two-year-later routes): Families targeting Magdalen College School's dedicated state-school pathway have a full extra year of runway, with registration not closing until 31 October 2026 and exams sat on 16 January 2027. Use the additional time deliberately: build creative-writing skills specifically (a Magdalen College School paper component many state-school curricula do not emphasise), and rehearse interview technique ahead of the school's 26-27 January 2027 interview dates.

Yes. State-school applicants are an established part of 13+ admissions at many leading independent schools, not an exception. Wellington College reports that 16% of its Year 9 joiners come from state, grammar and 11-18 day schools, with a further 11% joining from international backgrounds — meaning well over a quarter of the cohort arrives without a traditional prep-school background. King's School Canterbury runs a dedicated "Non-Prep School & International" entry route alongside its prep-school pathway, and Canford School states directly that while many pupils come from independent prep schools, "we also welcome pupils from a wide range of other educational backgrounds." The barrier parents assume exists is smaller than it looks.
In most cases, yes — the ISEB Common Pre-Test is the standard first-stage assessment used by the majority of 13+ independent schools, and it is sat in Year 6 regardless of which type of school a child currently attends. It covers English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning across four adaptive, multiple-choice papers totalling 2 hours 15 minutes, taken between the autumn and spring terms. Registration is parent-led through ISEB's Guardian Portal rather than arranged by the school, and children who cannot sit it at their own school can usually test at an approved invigilation centre — Cranleigh School, for example, explicitly allows candidates from schools that do not offer the ISEB test to sit it at Cranleigh Prep School.
King's School Canterbury has the clearest dual-track system: pupils from prep schools sit the ISEB Common Pre-Test in Year 6 followed by an Experience Day, while pupils from non-prep, state or international schools sit King's own Entrance Exams (KEE) instead, administered at King's, the candidate's current school, or an approved centre. Around 150 pupils join King's at Year 9 each year across both routes. Magdalen College School operates a similarly explicit split — its Year 9 entry process is aimed specifically at "candidates who are currently in Year 8 at a state school, or at an independent school that does not prepare candidates for Common Entrance or PSB," with prep-school pupils directed to its separate pre-test route instead.
For September 2027 entry, Wellington College's online registration for the ISEB Common Pre-Test closes at 12 noon on 30 June 2026, against a non-refundable £400 registration fee. The pre-test itself is sat in October or November 2026, and offers are made in March 2027 — conditional only on the child's current school providing a satisfactory report at the end of Year 8, not on attending a particular type of school beforehand. Families intending to apply from a state school should register by this date regardless of whether their child's school has prepared them for Common Entrance.
Yes, and fees vary by school. Wellington College charges a non-refundable £400 registration fee for its Year 6 assessment. Magdalen College School charges £180 for UK-based candidates and £300 for candidates applying from overseas. These fees are separate from the ISEB Common Pre-Test's own administration cost where that test is used, and from any subsequent second-stage assessment or interview fees some schools charge. Families should check each school's own admissions page directly, as fees and deadlines are set independently by each school and change from year to year.
For September 2027 entry, Magdalen College School's registration for its Year 9 non-prep-school entry route closes on 31 October 2026. The written and online entrance examinations are sat on 16 January 2027, covering Maths, Non-Verbal and Verbal Reasoning, a Creative Writing paper, and English with problem-solving. Interviews for shortlisted candidates take place on 26-27 January 2027, results are announced on 4 February 2027, and the acceptance deadline is 1 March 2027. This full cycle runs entirely within Year 8, later than the Year-6 ISEB pre-test route used by prep-school pupils continuing straight through.
This is a common situation for state-school families and is explicitly accommodated by several schools. Cranleigh School states that applicants from schools that do not offer the ISEB test "can sit the test at Cranleigh Prep School, in arrangement with the Admissions Team" between October and mid-November of Year 6. Sevenoaks School's assessment for entry in 2027 runs an ISEB testing window from 1 September to 27 November 2026 and does not restrict eligibility by current school type, instead assessing candidates on a second-stage English and Maths paper plus a 40-minute group discussion. Parents should contact the admissions office of any target school directly to confirm the nearest approved test centre.
