What the test actually involves — sourced from ISEB and GL Assessment, not from a tutoring directory
Book a Free ConsultationAt 13+, non-verbal reasoning is far rarer than the tutoring market assumes. ISEB's own Common Entrance specification for 13+ entry — sat in Year 8, with three compulsory papers in English, mathematics and science — carries no non-verbal reasoning paper at all. The non-verbal reasoning most families associate with "13+" actually belongs to the ISEB Pre-Test, a test ISEB itself brands "(11+)" and which most senior schools sit in Year 6 or Year 7, one to two years before a child turns 13. This page works from ISEB's, GL Assessment's and named schools' own admissions pages to explain what the test actually contains, how it is scored, when it really happens, and what preparing for it can and cannot change.
Non-verbal reasoning has a specific, testable shape, and it is worth knowing before anything else on this page. According to GL Assessment's own support documentation for its NVR 12-14 assessment — the age band that covers most 13+ candidates — the test "contains two basic types of question: classification questions and matrix, series and analogy questions." Classification questions ask a pupil to find another member of a set among six shapes; the pupil is not told what the "rule" connecting the set is and has to work it out from the examples given.
The second group is broader. GL Assessment's guidance describes matrix-style questions as being "either 2x2, 2x3 or 3x3 matrices, which contain elements of series and analogies," alongside three other presentation styles: horizontal rows (a straightforward series in one case, an analogy in the other), star shapes, where a pupil identifies patterns or analogies between different areas of a design, and a "two triangles" format, described as "another way of presenting a set of analogies." In every case the pupil is choosing which of six candidate figures completes the pattern — there is no reading or writing involved, which is the entire point of a "non-verbal" test.
Non-verbal reasoning (NVR) and verbal reasoning (VR) are frequently bundled together in tutoring marketing, but they test genuinely different things. GL Assessment's CAT4 — Cognitive Abilities Test, a separate diagnostic tool many schools use for internal profiling rather than admissions — describes its non-verbal reasoning battery as "problem-solving using pictures and diagrams," distinct from its verbal reasoning battery, which assesses "the ability to express ideas and reason through words." CAT4 reports across four batteries in total: verbal, non-verbal, spatial and quantitative reasoning. If your search is really about the verbal side of 13+ preparation, our companion page on 13+ verbal reasoning covers that test in full — this page deliberately does not duplicate it.
ISEB's own framing of why both matter is useful. Its guidance for schools distinguishes what English and mathematics measure from what verbal and non-verbal reasoning measure: the former test "attainment" — what a pupil has been taught — while "the verbal and non-verbal reasoning tests enable pupils to demonstrate their academic potential through a range of question types that may be unfamiliar to them." That distinction — attainment versus potential — is why reasoning papers exist alongside subject papers in the first place, and it matters again later on this page when it comes to what preparation can realistically change.
Search "13+ non-verbal reasoning" and the assumption baked into almost every result is that a 13-year-old sitting a senior school's 13+ exam will face a non-verbal reasoning paper. ISEB's own Common Entrance page says otherwise. Common Entrance (CE) "in use since 1903," is set directly by ISEB, and at 13+ it works like this: "Pupils sit the CE assessment at 13+ when they are in Year 8, and there are three examination sessions each year; in November, January and May/June. All pupils sit three compulsory papers; English, mathematics and science, and they may be required to sit additional papers in a wide range of subjects including geography, history, classics, modern foreign languages, and theology, philosophy and religion." Non-verbal reasoning is not listed among the compulsory papers or the optional ones. The same is true of CASE, the scholarship-level companion to CE at 13+, which ISEB describes as built "based on our CE at 13+ specifications" — the same subject list, the same absence of a reasoning paper.
So where does the non-verbal reasoning genuinely central to "13+ NVR" searches actually live? In the ISEB Pre-Test — a completely separate ISEB product, four online, adaptive papers covering "English, mathematics, verbal reasoning (VR) and non-verbal reasoning (NVR)." Crucially, ISEB's own schools' guidance names it "the official Pre-Tests (11+) Test Framework," and states plainly: "The tests are designed for pupils in Years 6 and 7. Some senior schools use the tests for admissions into Year 7, whilst others use it for entry into Year 9." A senior school deciding a Year 9 (13+) place can therefore lean entirely on a non-verbal reasoning score that was generated one or two academic years earlier, inside a product ISEB itself brands as an "11+" assessment. For the wider Common Entrance picture beyond non-verbal reasoning, see our Common Entrance 13+ guide, and for the Pre-Test mechanism itself, our ISEB Pre-Test guide.
Not sure which test your child is actually facing? Whether the real assessment is the Year 6/7 ISEB Pre-Test or a school-set 13+ paper, Leading Tuition's specialist tutors build a plan around the exam that is genuinely coming, not a generic "13+ NVR" package.
Book a Free Consultation Message us on WhatsAppThe practical consequence of the Pre-Test's timing is that a family who starts looking for "13+ non-verbal reasoning tutoring" once their child is in Year 8 has, for most senior schools, already missed the window. ISEB's published dates for the 2026-2027 Pre-Test session confirm how early this sits: the Guardian Portal for parents and guardians opens for registration on Tuesday 9 June 2026, live testing begins on Tuesday 1 September 2026, and the session runs through to late May 2027. ISEB is explicit that "pupils can only sit the ISEB Pre-Tests once in any academic year" — there is no resit within the same cycle if a school wants a different result.
Rugby School's own admissions pages give a concrete, named example of how this plays out for a real 2027 entry cohort. Rugby confirms that its "entrance assessments include: Academic: English, Maths, Verbal Reasoning and Non-Verbal Reasoning" for both 13+ Boarding and 13+ Day applicants, and that "for 2027 entry, the Year 6 Assessment Day will take place on Thursday 26 November 2026," with "Year 7 candidates" invited "to attend on either 7 or 9 October" the same year. Its 13+ Scholarship assessments, sat by pupils applying for an academic or Foundation award, run later still — "in the Advent and Lent terms of Year 8" — but by that stage the school-set academic papers, not a fresh non-verbal reasoning score, are what decide the outcome. In every case, the non-verbal reasoning component is behind the family well before the September a child actually starts Year 9.
Understanding the score matters as much as understanding the format. ISEB's guidance to schools sets out exactly what a Pre-Test result contains: "A Standardised Age Score (SAS) which is based on the accuracy of the pupils' answers and their consistency. The score is adjusted for age and placed on a scale which makes a comparison with a standardisation sample taken from the independent schools' sector (the average is 100)." Alongside the SAS, senior schools also see "individual stanine, percentile rank and group rank scores, together with mean SAS" — several different ways of expressing the same underlying performance.
| Score element | What it shows |
|---|---|
| Standardised Age Score (SAS) | Age-adjusted score against the independent-sector sample; average is 100 |
| Stanine | A nine-band summary derived from the SAS |
| Percentile rank | Position relative to the standardisation sample, also derived from the SAS |
| Group rank | Ranking among a school's own applicant group for that session |
The test is also adaptive: ISEB explains that "the test system will assess the pupil's ability after each response and select the next question to have the most appropriate level of difficulty," so two children rarely see the same sequence of non-verbal reasoning questions, and a pupil "cannot go back and change previous answers" once submitted. Families requesting access arrangements should know that ISEB allows applicants with SEND "additional time of 25%" to complete each element of the Pre-Test — including the non-verbal reasoning paper — where a senior school agrees and appropriate evidence, usually an Educational Psychologist's report, has been provided.
This page is deliberately not a school-by-school directory — that level of local detail belongs to our dedicated location guides, linked below. But it is worth knowing the shape of the market. Rugby School's own admissions pages are the clearest verified example: Non-Verbal Reasoning is explicitly named among the "Academic" entrance assessments for both its 13+ Boarding and 13+ Day routes. Separately, one test-prep retailer's own product catalogue lists 16 senior schools selling a dedicated 13+ practice product that spans non-verbal reasoning alongside maths, English and verbal reasoning — a commercial listing rather than an official confirmation from each school, but a useful indication of how many schools the market believes are relevant.
Mill Hill School is one frequently cited example of a school whose 13+ route genuinely does include an adaptive non-verbal reasoning component — our Barnet 13+ non-verbal reasoning guide covers its format, dates and fees in full, so this page does not repeat them. For the wider picture of which named schools near a specific area do and do not test non-verbal reasoning at 13+, see our Bromley and Harrow guides — each verifies school by school, against that school's own admissions pages, rather than assuming.
ISEB's own framing of the Pre-Test is a useful starting point for preparation, because it tells you what the test is designed to resist. English and mathematics test "attainment" — curriculum content a child has been taught. Verbal and non-verbal reasoning, by contrast, are designed so that pupils "demonstrate their academic potential through a range of question types that may be unfamiliar to them," assessing "the ability to analyse, think critically, find patterns, and problem-solve." That framing does not mean practice is pointless — familiarity with classification and matrix-style formats reduces the time a child spends decoding an unfamiliar question type rather than solving it — but it does mean that no amount of drilling turns non-verbal reasoning into a memorised subject the way a mathematics topic can be.
For families preparing specifically for the ISEB Pre-Test, ISEB itself endorses one practice platform over any other: "we have worked with our partners, CENTURY and Bond (Oxford University Press), to develop and introduce the only ISEB-endorsed test practice platform, Bond Online Premium Plus." ISEB is explicit that it "cannot guarantee the accuracy of third-party Common Pre-Tests practice resources that are not endorsed by ISEB," which is a reasonable caution given how many generic "13+ NVR" packages are sold without reference to which school, or which of ISEB's own products, a family is actually preparing for.
No. ISEB's own Common Entrance specification confirms that the 13+ assessment, sat in Year 8, consists of three compulsory papers — English, mathematics and science — plus optional subjects such as geography, history, classics, modern foreign languages, and theology, philosophy and religion. Non-verbal reasoning is not among them, and the same is true of CASE, the 13+ scholarship version of Common Entrance, which is built on the same specification. Common Entrance has been used since 1903, and its subject list has never included a dedicated reasoning paper at 13+.
Inside the ISEB Pre-Test, officially the "ISEB Pre-Tests (11+)" — four online, adaptive papers covering English, mathematics, verbal reasoning and non-verbal reasoning. ISEB's own admissions guidance states the tests are designed for pupils in Years 6 and 7, and that some senior schools use them for Year 7 entry while others use the same tests to decide Year 9, deferred 13+ places. A child's non-verbal reasoning is therefore usually assessed one to two years before they turn 13, not at 13 itself.
GL Assessment's own NVR 12-14 test — the age band covering most 13+ candidates — contains two basic question types: classification questions, where a pupil finds another member of a set, and matrix, series and analogy questions. The second group is presented in several formats, including 2x2, 2x3 and 3x3 matrices, horizontal-row series, star-shape patterns and two-triangle analogies. Every question is multiple-choice, asking the pupil to pick which of six figures completes the pattern.
ISEB reports a Standardised Age Score (SAS), adjusted for the pupil's age and benchmarked against a standardisation sample from the independent sector, where the average score is 100. Results also include a stanine, a percentile rank and a group rank. Because the test is adaptive, no two pupils see quite the same sequence of questions, and once an answer is submitted a pupil cannot go back and change it — so the effective length of the test varies from child to child.
Yes. Where a senior school agrees and appropriate evidence — usually an Educational Psychologist's report — has been provided, ISEB allows applicants with SEND an additional 25% of time to complete each element of the Pre-Test, including the non-verbal reasoning paper. Parents request this during registration on the Guardian Portal, and the relevant senior school reviews the supporting evidence before confirming the arrangement. The on-screen timer can also be hidden for pupils who find a visible countdown stressful.
No, and confusing the two is a common mistake. CAT4 is GL Assessment's separate cognitive abilities test, reporting across four batteries — verbal, non-verbal, spatial and quantitative reasoning — and many schools use it for internal diagnostic profiling or setting rather than as a pass/fail admissions gate. The Pre-Test's non-verbal reasoning paper, by contrast, is one specific admissions assessment set by ISEB. A school might use both, for different purposes, in the same academic year.
It varies far more than the tutoring market assumes. Rugby School's own admissions pages confirm that its Academic entrance assessments — for both 13+ Boarding and 13+ Day — include Non-Verbal Reasoning alongside English, Maths and Verbal Reasoning. One test-prep retailer's own catalogue separately lists 16 senior schools selling a dedicated 13+ practice product spanning non-verbal reasoning, though that is a commercial listing, not an official one. For hyper-local detail on named schools, see our Barnet, Bromley and Harrow guides.
Earlier than a "13+" search implies, for most schools. Rugby School's Year 6 Assessment Day for 2027 entry falls on Thursday 26 November 2026, with Year 7 candidates invited on 7 or 9 October the same year — both roughly two years before a September Year 9 start. Because the ISEB Pre-Test's non-verbal reasoning paper is sat in this same Year 6 or Year 7 window, effective preparation needs to be under way well before a child's 13th birthday, not after it.
