Wilson's School in Wallington is a boys-only selective grammar and one of the four Sutton grammar schools, alongside Sutton Grammar, Wallington County Grammar and Wallington High School for Girls. It is heavily oversubscribed and consistently ranks among the strongest state schools in the country, which means the entrance test is genuinely competitive rather than a formality. This guide sets out how the Sutton admissions process actually works, the scores families need to aim for, how the distance rules shape your realistic chances, and how to prepare so your son arrives ready for a long, fast, reasoning-heavy paper.
How the Sutton consortium test works
The four Sutton grammars share a common entrance test run as a two-stage process in the autumn term of Year 6. You register your son once with the consortium and rank the schools in order of preference. The test is set by GL Assessment and reflects the current post-CEM landscape: multiple-choice questions answered on a separate machine-marked answer sheet, tightly timed, with no calculator allowed. Understanding both stages matters, because each does a different job.
- Stage 1 takes place in mid-September and combines English, Maths, Verbal Reasoning and Non-Verbal Reasoning into a mixed paper of roughly 90 minutes. It is designed to filter the large applicant pool down to a shortlist of around 600 boys across the consortium.
- Stage 2 follows in mid-October for those who pass Stage 1. It is a longer, more demanding reasoning and comprehension paper. Wilson's then makes offers to approximately the top 175 boys, allocated according to its own admissions criteria.
Because the two stages are close together, there is little time to fix weaknesses between them. Preparation needs to be largely complete before September, with the weeks in between used for light practice and rest rather than cramming.
The qualifying score you are aiming for
Sutton scores are standardised, meaning raw marks are converted onto an age-adjusted scale so that a summer-born boy is not disadvantaged by being younger than his peers. The scale runs roughly from 69 to 141, with 100 as the national average. To progress past Stage 1, boys typically need a standardised score of around 121 or higher. Stage 2 then re-ranks the qualifying cohort to select Wilson's intake.
Two important cautions. First, exact thresholds move each year with the size and strength of the cohort and the number of places available, so treat 121 as a working target rather than a fixed pass mark. Second, a qualifying score does not guarantee a place: because Wilson's is so oversubscribed, the distance and ranking rules below often decide who actually receives an offer.
Places, ranking and distance
Wilson's splits its intake between academic rank and proximity. Broadly, a portion of places goes to the highest-scoring qualified boys regardless of where they live, and the remainder are allocated by distance to those who qualify, favouring families inside a tight inner radius of roughly two miles. The practical effect is that a very high score can secure a place from further away, while a solid-but-not-exceptional score is far more likely to succeed for a family living close to the school.
| Factor | What it means for your application |
|---|---|
| Qualify at Stage 1 (~121+) | Entry ticket only — required, not sufficient |
| Top-ranked scores | A block of places offered on rank alone, distance-blind |
| Inner catchment (about 2 miles) | Remaining places favour nearby qualified boys |
| Sibling / looked-after criteria | Priority categories set out in the admissions policy |
Always check the current admissions arrangements on the school and consortium websites for the exact year of entry, as the split between ranked and distance places and the priority categories are reviewed periodically.
What the paper actually tests
The Sutton test covers the four familiar 11+ skill areas, and Wilson's boys need to be comfortable across all of them rather than leaning on one strength:
- English — reading comprehension with inference and retrieval, vocabulary in context, spelling, punctuation and grammar.
- Maths — number, fractions, decimals, percentages, ratio, algebra and function machines, geometry and multi-step word problems, worked mentally under time pressure.
- Verbal Reasoning — synonyms, antonyms, analogies, letter and number codes, and logic questions.
- Non-Verbal Reasoning — series, matrices, rotation, reflection and odd-one-out puzzles.
You can drill each of these free of charge through Quest Arena's worksheets and time your son against the clock with our mock papers.
How to prepare for a long, fast test
The Sutton format is one of the longer 11+ experiences, so stamina matters as much as accuracy. A boy who is strong for ten minutes but fades over ninety will lose easy marks late in the paper. Build preparation around a "little and often" routine from early Year 5, then shift toward full timed papers in the summer before the test.
- Master the content first using untimed revision practice, one topic at a time.
- Add strict timing — aim for roughly a minute per Maths and English question and 30 to 45 seconds per reasoning question.
- Teach answer-sheet discipline: transfer answers cleanly, and if a question is slow, mark a best guess and move on rather than stalling.
- Sit full-length mocks under exam conditions to build endurance and reduce nerves.
Quest Arena's centre-specific library includes Sutton-style mocks that mirror the two-stage structure, and our key dates page helps you plan registration deadlines. For the wider picture of how selective entry works, see the 11+ process guide and the grammar school directory.
Frequently asked questions
Is Wilson's School boys-only?
Yes. Wilson's is a selective boys' grammar. Families seeking a girls' grammar in the same consortium usually consider Wallington High School for Girls or Nonsuch, while Sutton Grammar and Wallington County Grammar are the other boys' options.
What score does my son need to pass?
As a rough guide, a standardised score of around 121 or above is needed to clear Stage 1, but the real threshold shifts each year with the cohort. Distance and rank then decide offers among qualified boys, so a place is never guaranteed by score alone.
When should we start preparing?
Most families begin gentle preparation in Year 4 or early Year 5, giving a 12 to 18 month runway. That allows content mastery first, then timed practice and full mocks in the summer before the September test, without last-minute cramming.
