Wellington Entrance Exam: What to Expect and How to Prepare

Wellington College assesses its 13+ candidates in two stages, and only the first involves a written test. Stage one is the ISEB Common Pre-Test, taken online in Year 6. Stage two is an assessment day at Wellington built around collaborative lessons and activities, not a further exam, alongside an online interview. Wellington describes this as a whole-child approach, looking at how a candidate thinks, listens and works with others. Knowing what each stage involves is the difference between focused preparation and effort spent on the wrong thing. This guide explains the process and how to prepare.

The two-stage process

Wellington assesses 13+ candidates in two stages, and it is worth being clear that only the first is a written test. Stage one is the ISEB Common Pre-Test, sat online in Year 6, which together with a head teacher's reference is used to decide who is invited onward. Stage two is an assessment day at Wellington for shortlisted candidates, built around collaborative lessons and problem-solving activities rather than a further exam, alongside an interview with a senior member of pastoral staff held online on a separate day. This structure tells you a great deal about what Wellington values: a sound academic foundation measured by the pre-test, and then a close look at how a child engages, collaborates and thinks when there is no exam to revise for. Our guide to the Wellington interview covers that part in detail.

The ISEB Common Pre-Test

The only written assessment for 13+ entry is the ISEB Common Pre-Test, taken in October or November of Year 6. It is an online, adaptive, age-standardised test, sat at your child's current school or, for overseas candidates, at the British Council or an approved centre. It covers four areas: Maths, lasting around fifty minutes; English, covering comprehension and spelling, punctuation and grammar, lasting around twenty-five minutes; Verbal Reasoning, around thirty-six minutes; and Non-Verbal Reasoning, around thirty-two minutes, taking a little over two hours in total. Because it is adaptive, the questions adjust to your child's answers as they go, and because it is age-standardised, it measures your child against others of exactly the same age in months, so a summer-born child is not disadvantaged. Our dedicated guide to the ISEB Common Pre-Test covers the test in full.

The assessment day

Candidates who do well at the first stage are invited to an assessment day at Wellington, usually in January or February of Year 6, and this is deliberately not a written test. It is a half-day built around three collaborative lessons or problem-solving activities, designed to let the school see how a child engages with academic work and with their peers. There are no further exams on the day. The point is to watch how a child thinks, listens, contributes to a group, and behaves alongside other children, in a setting that feels more like a normal school day than an examination. For a child who is genuinely curious, works well with others and joins in readily, the day is a chance to show qualities that a written paper cannot capture.

The whole-child approach

Wellington describes its selection as a whole-child approach, and the assessment is built around it. Rather than ranking children by a single exam score, the school weighs the pre-test, the assessment day, the interview and the reference together to judge both academic potential and how a child will fit into the community. Wellington says it is looking for engagement, determination and joy in learning, and for how candidates think, listen, contribute and behave around their peers. This matters for preparation because it means the qualities that count are not all academic. A child who is curious, resilient, kind to others and genuinely enthusiastic about learning is showing exactly what Wellington wants to see, and these are qualities that grow over time rather than being coached in a few weeks.

How to prepare

Because Wellington assesses in two stages that reward different things, preparation should match both. For the pre-test, the foundation is secure English and Maths built early, with wide reading to support comprehension, and because the test is timed, adaptive and on-screen, some online practice under realistic conditions is worth doing so the format holds no surprises. For the assessment day, the best preparation is the kind that builds genuine curiosity and the ability to work with others: a child who reads widely, pursues real interests, and is used to discussing ideas and collaborating will engage naturally in the collaborative lessons. For the interview, a calm, confident child who can talk warmly about what they enjoy is well placed. Throughout, take Wellington's whole-child approach at face value and aim for a genuinely engaged, well-rounded child rather than a drilled one.

What to avoid

The first thing to avoid is treating the pre-test as the whole assessment. It is only the first stage, and the assessment day, the interview and the reference all carry weight in a whole-child review. The second is trying to coach for the assessment day as if it were an exam, when in fact it rewards genuine engagement and collaboration that cannot be crammed. The third is neglecting the qualities Wellington explicitly values, such as listening, working well with others and a real enthusiasm for learning, which matter as much as academic attainment. Prepare for both stages, build genuine curiosity and good collaboration, and let your child's character show.
