If you're weighing up one of Sutton's super-selective grammar schools for a Year 6 application, here's what the numbers actually say. In 2025, Sutton Grammar School posted 67.0% A*-A at A-level and 33.3% grade 9s at GCSE. Wallington County Grammar School posted 67% A*/A at A-level and 24% grade 9s at GCSE. Wallington High School for Girls posted 56% A*/A at A-level and roughly 83% at grades 9-7 at GCSE. All three run second-stage papers covering English and Maths only: no multiple choice, no verbal or non-verbal reasoning. Only the girls' shared NWSSEE paper spells out, in its own published wording, that there's no comprehension component. Below, we go through each school's published results in detail, plus what we could and couldn't confirm about the second-stage English paper at each one.
The Sutton grammar school landscape
Sutton borough has some of the most competitive state grammar schools in the country. Families researching the 11 plus here are usually looking at five schools: Sutton Grammar School and Wilson's School for boys, Nonsuch High School for Girls and Wallington High School for Girls for girls, and Wallington County Grammar School, also for boys. All five sit inside a super-selective system, which means your child typically needs to clear a very high pass mark on the 11 plus rather than just scrape past a minimum threshold. Catchment tends to matter less here than at other grammar schools too, since these schools draw applicants from across south London and Surrey rather than a tight local area.
This article covers the three schools where we could verify 2025 results directly from the schools' own published documents: Sutton Grammar School, Wallington County Grammar School, and Wallington High School for Girls. We haven't included results figures for Wilson's School or Nonsuch High School for Girls, because we couldn't verify current numbers directly against their own sites at the time of writing. Treat any figures you see elsewhere for those two schools with some caution until you've checked the school's own published results page.
Sutton Grammar School: 2025 results in full
Sutton Grammar School's own results PDF, published on the school's website and amended as of 16 October 2025, gives a detailed picture of a school with 180 pupils in the year group and 600 A-level entries. At A-level, 67.0% of entries were awarded A*-A, 87.0% achieved A*-B, 95.2% achieved A*-C, and 99.7% achieved A*-E. At GCSE, with 133 pupils across 1,478 entries, 33.3% of entries were awarded the top grade 9 on its own, 60.6% achieved grades 9-8, 81.1% achieved grades 9-7, 93.6% achieved grades 9-6, and 98.0% achieved grades 9-5. The school's Attainment 8 score for 2025 was 80.3, rising to 80.8 when history iGCSE is included. Attainment 8 measures a pupil's average grade across eight qualifying subjects, so a score in the 80s puts Sutton Grammar well above the national average.
Wallington County Grammar School: 2025 results in full
Wallington County Grammar School publishes its own summary PDFs for both A-level and GCSE results, and the 2025 figures show a school on a clear upward trend. At A-level, across 596 entries, 24% achieved the top A* grade on its own, 67% achieved A*/A, 87% achieved A*-B, and 96% achieved A*-C. The school's own three-year trend data tells the story here: A*/A moved from 52% in 2023, to 62% in 2024, to 67% in 2025. At GCSE, across 1,729 entries, 24% of entries were grade 9, 51% achieved 8 or above, 73% achieved 7 or above (grades 9-7), 91% achieved 6 or above, 98% achieved 5 or above, and 99% achieved 4 or above.
Wallington High School for Girls: 2025 results in full
Wallington High School for Girls publishes per-subject A-level and GCSE results as PDFs rather than one overall summary line, so the whole-school figures below combine the school's own stated summary with our entry-weighted calculation from its per-subject tables. At A-level, the school's own results page states plainly that 22% of all entries were awarded an A*, and 56% achieved grades A*-A, with 85% at A*-B. We recalculated the A*/A figure ourselves by weighting the school's per-subject percentages across 761 entries (excluding the non-A-level EPQ) and arrived at roughly 56.1%, which matches the school's stated 56% almost exactly.
At GCSE, the school doesn't print one single overall 9-7 figure, so we entry-weighted the per-subject 9, 8 and 7 percentages across all 26 subjects and 2,215 total entries. That calculation comes out at approximately 83.4% achieving grades 9-7, close to the commonly cited external figure of 83% for the school. The school's own published data also confirms that 35% of entries were grade 9, 65% were at grade 8 or 9, and 99.5% of entries achieved strong 9-5 passes in English and Maths specifically. Because the 9-7 figure is our own calculation from the school's per-subject data rather than a single printed line, treat it as a close approximation rather than a school-quoted statistic.
How the three schools compare on results
Put the three schools' 2025 A-level figures side by side and the differences are easier to see, though Sutton Grammar doesn't publish a standalone A* percentage, only the combined A*-A figure.
| School | A* | A*-A | A*-B | A*-C |
|---|---|---|---|---|
| Sutton Grammar School (boys) | not published separately | 67.0% | 87.0% | 95.2% |
| Wallington County Grammar School (boys) | 24% | 67% | 87% | 96% |
| Wallington High School for Girls (girls) | 22% | 56% | 85% | not published |
At GCSE, the same three schools compare like this.
| School | Grade 9 | 9-8 | 9-7 | 9-6 | 9-5 |
|---|---|---|---|---|---|
| Sutton Grammar School | 33.3% | 60.6% | 81.1% | 93.6% | 98.0% |
| Wallington County Grammar School | 24% | 51% | 73% | 91% | 98% |
| Wallington High School for Girls | 35% | 65% | approx. 83.4% (calculated) | not published as a single line | 99.5% (English and Maths) |
On these figures, Sutton Grammar and Wallington County Grammar sit close together at A-level, with Wallington County Grammar's A*/A rate matching Sutton Grammar's exactly at 67% in 2025. At GCSE, though, Wallington High School for Girls comes out on top: its 35% grade-9 rate is the highest of the three schools shown here, ahead of Sutton Grammar's 33.3% and Wallington County Grammar's 24%.
What is the Sutton SET, and how does the second stage work?
Sutton Grammar School and Wallington County Grammar School both sit within what's often called locally the Sutton SET system, and both use a two-stage entrance process. Candidates who clear the first stage move on to a second-stage exam made up of two papers: an English paper and a Maths paper. Both schools' own FAQ pages describe this second-stage test in similar, deliberately generic wording: not multiple choice, no verbal or non-verbal reasoning, and content broadly based on the Key Stage 2 curriculum. Sutton Grammar's own FAQ page adds that each paper runs around 45 minutes to an hour; Wallington County Grammar's own FAQ text doesn't give a specific duration.
What neither school says, in its own words, is which specific genre of writing the English paper requires. Third-party 11+ tutoring sites commonly describe the paper as containing two pieces of extended or creative writing, often one fiction task and one non-fiction task such as a letter or speech, but that description comes from tutoring companies, not from suttongrammar.sutton.sch.uk or wcgs-sutton.co.uk directly. If you're preparing your child for the Sutton SET second stage, treat that third-party description as a helpful guide to what tends to come up, not as an official exam specification.
What is the NWSSEE, and does it test creative writing?
The Nonsuch and Wallington Second Stage Entrance Examination, or NWSSEE, is the shared second-stage paper used by Nonsuch High School for Girls and Wallington High School for Girls. Wallington Girls' own page describing the NWSSEE is more explicit than the boys' schools' pages. It states there are two elements, an English paper and a Maths paper, each lasting between 40 and 50 minutes, and crucially that there is no comprehension paper for English in the NWSSEE. Candidates are also warned that answers which are obviously prepared beforehand and don't address the form or task set will not be rewarded any marks: the school's own way of saying pre-learned essays will be penalised, and that your child needs to respond originally to whatever prompt comes up on the day.
The phrase creative writing doesn't appear word for word in that page, but ruling out a comprehension component and requiring an original, task-specific piece of extended writing amounts to much the same thing in practice. That makes the NWSSEE description the most explicit of the four schools' published wording when it comes to confirming what the English paper actually tests. This description comes from Wallington High School for Girls' own copy of the shared NWSSEE page; we couldn't independently verify identical wording on Nonsuch High School for Girls' own site, though as a shared exam paper the same format applies to both schools.
Sutton SET versus NWSSEE: the key difference for parents
If you're applying to more than one of Sutton's grammar schools, it helps to know that the Sutton SET (used by Sutton Grammar and Wallington County Grammar) and the NWSSEE (used by Nonsuch and Wallington High School for Girls) are two separate second-stage systems with their own papers, even though both are English-and-Maths-only, not multiple choice, and drop verbal and non-verbal reasoning entirely. The clearest documented difference: the NWSSEE explicitly rules out a comprehension paper in its own words and sets an original writing task instead, whereas the Sutton SET schools' own FAQ pages simply don't specify the writing genre at all. In practice, a familiarisation test or past paper aimed at one system may not map cleanly onto the other. If your child is sitting both, it's worth sourcing preparation materials for each separately rather than assuming one paper will fully prepare them for the other.
How Pip fits into your Sutton 11+ preparation
None of this changes the fact that the first stage for every one of these five Sutton schools, and for the vast majority of grammar school entrance routes nationally, still rests on strong core skills in English, Maths, verbal reasoning and non-verbal reasoning, built up steadily over Years 4 to 6. Whichever of Sutton's grammar schools you're aiming for, and whichever second-stage system your child will eventually sit, that foundational work is exactly what our free 11+ practice app is built around: daily adaptive questions across all four subjects, so your child keeps building fluency without every evening feeling like exam drilling. Once you're closer to the second-stage papers themselves, it's also worth reading our guide to how the 11 plus differs across exam boards. Knowing exactly what each paper does and doesn't test is half the battle when you're juggling more than one school's admissions process.

Sutton Grammar School's own 2025 results PDF records 67.0% of A-level entries at grades A*-A, rising to 87.0% at A*-B and 95.2% at A*-C. That's across 600 A-level entries from a year group of 180 pupils.
What GCSE results did Wallington County Grammar School get in 2025?+

How does Wallington High School for Girls' A-level performance compare to the other Sutton grammar schools?+
Wallington High School for Girls' own results page states 22% of A-level entries were awarded an A* and 56% achieved A*-A, with 85% at A*-B. That puts its A*/A rate below Sutton Grammar School and Wallington County Grammar School, which both recorded 67% A*/A in 2025, though we couldn't verify comparable figures for Nonsuch High School for Girls to complete the picture. At GCSE, though, Wallington High School for Girls' confirmed grade-9 rate of 35% is actually the highest of the three schools with verified 2025 figures.
Does the Sutton SET second-stage test include an essay or creative writing?+
Sutton Grammar School and Wallington County Grammar School's own FAQ pages describe the second-stage English paper only as not multiple choice and broadly based on the Key Stage 2 curriculum, without naming the writing genre. Third-party 11+ tutoring sites describe it as including extended or creative writing tasks, but that's not confirmed in either school's own published wording.
What is the NWSSEE and does it test creative writing?+
The NWSSEE, or Nonsuch and Wallington Second Stage Entrance Examination, is the shared second-stage paper for Nonsuch High School for Girls and Wallington High School for Girls. Wallington Girls' own page confirms there's no comprehension paper for English and that candidates must respond originally to a set task, which strongly implies an extended or creative writing component even though that exact phrase isn't used on the page.
What's the difference between the Sutton SET and the NWSSEE second-stage papers?+
Both systems test English and Maths only and rule out verbal and non-verbal reasoning entirely. Where a duration is published, papers run for roughly 40 minutes to an hour: Sutton Grammar and the NWSSEE both state a specific length in their own FAQ text, while Wallington County Grammar's own FAQ page doesn't give one. The clearest difference is that the NWSSEE explicitly rules out a comprehension component in its own published wording, while the Sutton SET schools' FAQ pages don't specify the writing genre at all, leaving that detail to third-party tutoring sites rather than the schools themselves.
