If you're looking at secondary schools in Sutton and wondering whether grammar school entry is realistic for your child, you're probably already aware that this borough is home to some of the most sought-after selective schools in the country. Wilson's School, Sutton Grammar School, Wallington County Grammar, Nonsuch High School for Girls, Wallington High School for Girls, and Greenshaw High School together form the Sutton Selective Eligibility Test (SET) consortium — six schools, one shared entrance exam, and 966 selective places for 2027 entry, with thousands of children competing each year. Understanding exactly how this process works, what the exam demands, and how to prepare effectively is the difference between a confident, well-targeted application and one that falls short despite a capable child.
The six consortium schools each have their own character and admissions criteria, but they share a single entry route: the Sutton SET. Wilson's School in Wallington is an all-boys grammar consistently ranked among the top state schools in England. Sutton Grammar School, also for boys, draws applicants from across South London and Surrey — its Published Admission Number rose from 135 to 150 for 2027 entry. Wallington County Grammar School is another boys' school with a strong academic reputation and fierce competition for places. Nonsuch High School for Girls in Cheam is one of the most oversubscribed girls' grammar schools in the country. Wallington High School for Girls, also in Wallington, is the borough's other girls' grammar and shares the same entry route. Greenshaw High School operates as a partially selective school, offering a proportion of places on academic ability alongside its broader intake.
Families often apply to multiple consortium schools simultaneously, which is one of the practical advantages of the shared exam — your child sits the SET once, and the result is used across all six schools. However, each school then applies its own admissions criteria, including distance, sibling priority, and in some cases catchment considerations, so a strong SET score does not guarantee a place at every school on your list. Independent schools in the same area run to a different calendar and a different test entirely: Sutton High School assesses girls on screen across November and December, and Ewell Castle School, just over the Surrey boundary, sets a 75-minute computer-based Quest paper with its 2027-entry sitting on 26 November 2026.
The Sutton SET is administered in early September of Year 6. It consists of two multiple-choice papers — Mathematics and English — taken on the same day; there is no verbal reasoning or non-verbal reasoning component. Children are assessed on their ability to work accurately under time pressure, using multiple-choice questions with a separate answer sheet, which is itself something children need to practise before the real thing.
English questions cover comprehension, grammar, punctuation, and vocabulary. The mathematics section tests content broadly in line with the Key Stage 2 curriculum, but the pace and question style demand fluency rather than just understanding. There is no verbal reasoning or non-verbal reasoning paper, which distinguishes the SET from reasoning-based 11+ systems used elsewhere.
One preparation mistake that catches many children out is treating the English paper as less important than maths. Because a timed, multiple-choice English paper is unfamiliar to most children, it deserves just as much structured practice as maths. Starting focused English preparation early — ideally twelve months before the exam — gives children time to become genuinely fluent under timed conditions rather than just familiar with the question types.
The level of competition in Sutton is not something to underestimate. Wilson's, Nonsuch, and Wallington are regularly cited among the most oversubscribed grammar schools in England. Each school receives far more applications than it has places to offer, and the children who receive offers are typically those who score in the top percentiles of an already self-selecting group of well-prepared candidates.
There is no single published pass mark for the SET — schools use a combination of standardised scores and their own admissions criteria to rank applicants. What this means in practice is that a child needs not just to pass a threshold, but to perform at a high level relative to every other child sitting the same exam on the same day. The standardised scoring process adjusts for age, which means younger children in the year group are not automatically disadvantaged, but it does not reduce the fundamental challenge of competing against a large, highly prepared cohort.
Our 11+ specialists work with students targeting Sutton selective schools, building the maths and English skills the borough's super-selective entry process rewards. Our students have achieved a 95%+ offer rate across selective school entry, and we're rated 4.8/5 on Trustpilot.

The SET takes place in the first week of September, which means preparation needs to be well underway before the summer holiday — not starting during it. Most families who achieve strong results begin structured preparation in Year 5, typically around twelve to eighteen months before the exam date. This is not about drilling a child relentlessly; it is about building genuine competence across both tested subjects so that the exam itself feels manageable rather than overwhelming.
A realistic preparation plan for Sutton families should build fluency in both tested subjects from the outset. Mathematics fluency — particularly speed and accuracy with arithmetic, fractions, and word problems — needs consistent practice rather than last-minute revision. English comprehension should be developed through wide reading alongside targeted question practice.
Timed practice papers are essential in the final three to four months before the exam, but they are most useful once a child has a solid foundation in each subject area. Sitting papers too early, before the underlying skills are in place, can knock a child's confidence without providing useful diagnostic information. The goal is to enter September feeling prepared, not exhausted.
Leading Tuition provides specialist 1-to-1 tutoring for children preparing for the Sutton SET. Our tutors are experienced with the SET's exact format and understand the specific demands of the consortium schools. Rather than working through generic 11+ materials, we tailor each child's programme to their starting point — identifying gaps in maths and English and building the exam technique needed to perform under timed conditions.
Working one-to-one means your child's tutor can respond to how they are actually progressing, not how an average child might progress. For a process as competitive as Sutton grammar school entry, that level of individual attention makes a genuine difference. We work with families across Sutton, Cheam, Wallington, Carshalton, and the surrounding areas, and we are familiar with the pressures and timelines that Sutton applicants face.
When does the Sutton SET take place, and when should we register?
The SET is held in early September of Year 6. Registration typically opens in the spring of Year 6, with deadlines usually falling in June or July. You should check the consortium's official website each year for exact dates, as these can vary slightly. Missing the registration window means missing the exam entirely, so it is worth setting a reminder well in advance.
Does my child need to sit separate exams for each Sutton grammar school?
No. The Sutton SET is a single exam used by all six consortium schools — Wilson's, Sutton Grammar, Wallington County Grammar, Nonsuch, Wallington High School for Girls, and Greenshaw. Your child sits the exam once, and you then apply to individual schools through the normal secondary school admissions process. Each school applies its own admissions criteria to rank eligible applicants.
What subjects does the Sutton SET cover, and how long is the exam?
The SET consists of two multiple-choice papers — Mathematics and English — sat on the same day, using a separate answer sheet; there is no verbal reasoning or non-verbal reasoning component. The total testing time across both papers is approximately two hours, though children should be prepared for the pace and format well before the exam day itself.
Is the SET harder than other 11+ exams, and how should we approach preparation?
The SET is a demanding exam, and the competition in Sutton is particularly intense given the reputation of the consortium schools. The exam itself is entirely multiple-choice across the two papers, but the cohort sitting it is large and well-prepared. Children who perform strongly tend to have built genuine fluency across both subject areas over a sustained period — typically twelve months or more — rather than relying on short-term cramming in the summer before Year 6.
