The SET Sutton Eleven Test: A Complete Guide for Parents (2026)

What Is the SET Sutton Eleven Test?

The Sutton Eleven Test is a shared entrance examination administered jointly by five selective secondary schools in and around the London Borough of Sutton. Rather than each school running its own separate test, all five schools agree on a single exam, administered on the same day each September. A child sits the SET once and the resulting score is shared with whichever SET schools the family has listed in their local authority application.

The test is developed and administered by GL Assessment, the same provider used by grammar schools in areas such as Bexley, Kent, and Buckinghamshire. However, the SET is classed as super-selective. This means the score threshold required for an offer is substantially higher than at standard grammar schools that also use GL Assessment papers. Passing a standard GL grammar test in a less competitive area might require a standardised age score (SAS) in the low 110s. At Wilson's School or Nonsuch High School for Girls, the typical qualifying score is 118 or above. At the other three SET schools, the working threshold sits around 115, though this varies year to year depending on cohort strength.

The consortium arrangement has practical implications for families. A child who scores 120 could receive preference consideration at all five schools simultaneously. A child who scores 113 may not qualify at any of them, even though a 113 would comfortably secure a place at many grammar schools elsewhere in England. This all-or-nothing characteristic is what makes early, structured preparation so important for SET candidates.

The test itself covers four curriculum areas: English, Mathematics, Verbal Reasoning, and Non-Verbal Reasoning. Each paper is separately timed, and the four scores are combined to produce a composite result. The composite is then standardised for age, meaning a child who sits the test just after their tenth birthday is not disadvantaged compared to a child who is nearly eleven at the time of sitting.

The Five SET Grammar Schools

Each of the five schools has its own admissions policy, but all use the SET score as the primary selection criterion. Here is a closer look at each school.

Wilson's School is widely regarded as one of the top state secondary schools in the country. It is a boys' school with a long academic tradition and consistently strong GCSE and A-level outcomes. Its Ofsted rating is Outstanding, and it regularly features near the top of national league tables for state schools. Because of its reputation, demand is exceptionally high, and the effective score threshold for a realistic offer is at the top end of the SET range.

Nonsuch High School for Girls is the girls' equivalent in terms of prestige and demand. Also rated Outstanding, Nonsuch has a reputation for producing strong academic results and an enriched co-curricular environment. Like Wilson's, it draws applications from families across a wide catchment, and the competition for places is intense.

Wallington County Grammar School is a boys' school that also holds Outstanding status and produces excellent results. Although the score threshold is typically a few points below Wilson's, the school is by no means an easy alternative. A score that secures a place at Wallington would put a child in the top few percent nationally.

Wallington High School for Girls shares a similar profile. It is consistently high-performing and oversubscribed, and it competes for the same pool of girls as Nonsuch. Families who list both schools are giving their daughter two genuine chances at a SET place with one sitting of the exam.

Sutton Grammar School is a boys' school that also performs strongly at both GCSE and A-level. It offers a broad curriculum and strong sixth form, and it is often the school that boys who narrowly miss Wilson's or Wallington County ultimately attend. All three boys' schools draw from largely overlapping applicant pools, so the score that earns a Wilson's offer will almost certainly also qualify a boy for the other two.

A note on gender and choice: because three of the five schools are for boys and two for girls, each family is effectively choosing between two or three schools for their child rather than all five. Boys may list Wilson's, Wallington County Grammar, and Sutton Grammar. Girls may list Nonsuch and Wallington High School for Girls. Families then also complete a separate Local Authority secondary school preference form, in which SET schools can be ranked alongside non-selective options.

The Four-Paper SET Format

English at SET level goes well beyond comprehension recall. Children are expected to interpret meaning, identify literary techniques, infer character motivation, and comment on how an author's word choices shape the reader's response. The passages used tend to be more complex and stylistically varied than those in standard 11-plus tests. Vocabulary questions may draw on words that are genuinely unusual for a Year 5 child, and the ability to work quickly under timed conditions is essential.

Mathematics at the SET covers the full KS2 curriculum and then some. Fractions, decimals, percentages, ratio, algebra, geometry, and multi-step word problems all appear. The difficulty lies not in exotic content but in the speed and precision required. A child who understands a concept but takes too long to apply it will run out of time. SET mathematics rewards both fluency and method.

Verbal Reasoning is a specialist paper type that many children encounter for the first time during 11-plus preparation. It tests the ability to understand and manipulate language through coded tasks rather than prose reading. Common question types include: finding words that complete analogies, identifying the odd word out, spotting hidden words within sentences, and working through letter and number codes. With practice, most children can improve substantially in verbal reasoning, making it one of the most trainable elements of the SET.

Non-Verbal Reasoning tests spatial and logical thinking using diagrams, shapes, and patterns rather than words or numbers. Children must spot rules, complete sequences, identify the shape that does not belong, or find which option completes a matrix. Non-verbal reasoning is less directly linked to school curriculum content, so raw practice with the question formats is especially important. Some children find this paper comes naturally; others need concentrated drilling to build speed and pattern recognition.

All four papers are taken in a single session on the test day in September. The exam is administered at various centres, typically in or near the Sutton borough. The papers are multiple-choice or short-answer in format, and results are returned as standardised age scores, with a mean of 100 and a standard deviation of 15 built into the standardisation model used by GL Assessment.

How Competitive Is the SET?

To understand what a SET score of 118 actually means, it helps to place it in the context of the wider population. Under the GL Assessment standardisation model, a score of 100 represents the average for that age group nationally. A score of 115 places a child roughly in the top 7 percent. A score of 118 places them in approximately the top 4 percent. A score of 120 or above, which is needed for a realistic chance at Wilson's or Nonsuch in a competitive year, places a child in the top 2 to 3 percent nationally.

Now consider that the SET applicant pool is not a random cross-section of the population. Families who enter their children for the SET are already a self-selected group: engaged, informed, and typically preparing specifically for selective entry. The effective competition is therefore much stiffer than the raw percentile suggests. A child who scores 115 nationally might be average or below-average within the SET cohort.

Approximately 3,000 children sit the SET each year. There are roughly 750 places across all five schools. That gives a headline ratio of 4 applicants per place. However, because each child can only attend one school, and because some children will receive multiple offers from different SET schools (and decline all but one), the effective competition for a place at any single school is more nuanced. At Wilson's, with around 180 places and applications from across the region, the true ratio for a single school may be closer to 8 or 10 to one.

Year-on-year variation in the cohort also affects the threshold. In a year where the pool of high-scorers is unusually strong, the effective cut-off may rise by a point or two. In a quieter year it may fall slightly. This unpredictability is one reason why preparation coaches and specialists generally advise families to aim well above the published threshold rather than targeting exactly 118. A child who consistently scores 122 in practice has meaningful headroom against year-on-year variation. A child who consistently scores 118 is sitting right at the edge.

The geographic spread of applicants adds another layer of complexity. Many SET applicants come from the London boroughs of Sutton, Merton, Croydon, and Kingston, as well as parts of Surrey. Out-of-area applicants may sit the same test and achieve qualifying scores, but distance from the school acts as a tie-breaker once the score threshold is met. A child who scores 120 but lives 15 miles away may be ranked below a child who scores 118 but lives within the priority distance band. Families living further from the Sutton schools need to be realistic about this, and may wish to hold non-selective or less competitive grammar school options as genuine alternatives.

How SET Compares to Standard GL Assessment

The table above highlights the key structural differences. Both tests use the same GL Assessment platform and the same standardisation methodology, but the bar for success at the SET is markedly higher. A child who could comfortably pass a standard grammar school entry test might still fall 5 to 8 points short of what is needed for the SET.

The four-paper structure is also more demanding than the two-paper format used in many GL Assessment grammar areas. Children who sit only English and Maths in a standard area have a narrower skills range to maintain. SET candidates must keep all four subject areas at a high level simultaneously, which requires more sustained and varied preparation.

One significant advantage of the SET consortium model is that a family only needs to manage one test registration and one test day for up to three (or two, for girls) grammar school options. By contrast, families applying to multiple non-consortium grammar schools may face separate test days, different providers, and different preparation needs for each school. The SET simplifies the logistical challenge even while raising the academic bar.

Registration: Key Dates and How to Apply

Registration for the SET typically opens in June or July of the year before secondary school entry, which means Year 5 families are registering during the summer term. The registration closes before the summer holiday begins, so families need to be aware of the timeline well in advance.

The process works as follows:

Step 1: Register for the SET. Families register directly with the SET consortium, usually through a dedicated registration portal. Registration is separate from the Local Authority secondary school application. You are not applying for a school place at this stage; you are registering your child to sit the examination. There is typically an administration fee. Registration confirmation will include the test centre allocation and timing.

Step 2: Sit the SET in September. The test is held on a Saturday in early to mid-September. All five schools use the same date and the same papers. Test centres are located in the Sutton area, and families are allocated to a centre based on their registration details. The full exam takes most of the morning, covering all four papers with breaks between.

Step 3: Receive results in October. Standardised age scores are returned to families in October, before the Local Authority secondary school application deadline. Families who receive a qualifying score can then list SET schools in their LA application with confidence. Families who do not reach the threshold have time to adjust their school preferences accordingly.

Step 4: Submit the Local Authority application. The deadline for secondary school applications in England is typically 31 October. Families must list their school preferences on the Local Authority form. Simply registering for the SET and achieving a qualifying score does not guarantee a place; the LA application must also name the relevant SET schools.

A note for out-of-area families: Children who live outside the London Borough of Sutton are eligible to sit the SET and may receive qualifying scores. However, when places are allocated, distance from the school is used as a tie-breaker among children who meet the score threshold. Families living in Croydon, Merton, Kingston, or parts of Surrey should check the individual admissions policies of each SET school for the exact distance priority bands.

Exact dates are published annually on each school's website and through the London Borough of Sutton. Families should check official sources each spring, as dates can shift slightly year to year. Waiting until September to begin researching dates risks missing the registration window entirely.

Preparation Strategy for the SET

A realistic preparation timeline for the SET begins in Year 4 or early Year 5 at the latest. Children who start in Year 5 spring term can still do well, but they will need to work efficiently and cover a large amount of ground in a relatively short time. Children who begin in Year 4 have the advantage of being able to build skills gradually, consolidate understanding, and approach the test from a position of genuine mastery rather than last-minute familiarity.

Phase 1: Foundation Building (Year 4 or early Year 5)

The first phase focuses on closing any curriculum gaps in English and Mathematics. This means solid arithmetic fluency, including times tables to 12, mental calculation strategies, and confident handling of fractions, decimals, and percentages. In English, the emphasis should be on vocabulary breadth, reading comprehension at a high level, and the ability to write clearly under time pressure.

During this phase, children should also be introduced to verbal reasoning and non-verbal reasoning as subjects. Many children have never encountered these paper types at school. Early exposure removes the novelty factor and allows time for genuine skill development rather than just familiarisation.

Phase 2: Skills Development (Year 5, spring and summer terms)

The second phase shifts to deliberate practice in all four subject areas. Children should work through GL Assessment-style practice papers under timed conditions. The key discipline here is accuracy first, then speed. Many parents make the mistake of pushing speed too early, which embeds careless habits. Speed improves naturally as accuracy becomes automatic.

Verbal reasoning in particular benefits from systematic vocabulary work. Learning common prefixes, suffixes, and root words gives children a toolkit for handling unfamiliar words in the VR paper. Reading challenging fiction and non-fiction independently is one of the most effective long-term investments a child can make.

Non-verbal reasoning should be practised with a wide variety of question formats. The GL Assessment NVR paper uses a consistent set of question types, and children who have seen all of them in practice are far better placed than those who encounter a format for the first time in the actual test.

Phase 3: Mock Exam Preparation (Year 5 summer holidays and early Year 6)

The six to eight weeks before the September test date are when full timed mock exams become the central focus. Children should sit complete four-paper mock SET exams under realistic conditions: timed, quiet, without parental assistance, and with the answer sheet format used in the real test.

After each mock, the analysis of errors is more valuable than the score itself. Which question types are consistently missed? Are there time management problems on a particular paper? Is the child making careless errors in mental arithmetic or misreading VR question instructions? Targeted follow-up practice on identified weaknesses is far more efficient than generic re-sitting of papers.

Eddy, EdifyPod's learning coach, supports this targeted approach by tracking where a child answers incorrectly and focusing follow-up practice on those specific gaps. Rather than repeating work the child has already mastered, the system concentrates effort where it will make the most difference, helping children make better use of the limited preparation time before September.

Managing wellbeing during preparation

The SET is a high-pressure exam, and children are acutely aware of the expectations placed on them. Parents play a crucial role in keeping preparation positive and sustainable. Setting a weekly routine with clear start and end times prevents preparation from bleeding into every corner of family life. Celebrating effort and improvement rather than only outcomes helps children stay motivated through setbacks.

Children who enter the test feeling calm and confident generally perform better than those who arrive anxious and depleted. The final week before the test should involve lighter practice and plenty of rest rather than a last-minute cramming push.

Is a SET School Right for Your Child?

The SET schools are outstanding institutions by any measure, but highly selective environments are not the right fit for every academically able child. Before investing significant time and energy in SET preparation, it is worth reflecting honestly on the following questions.

Does your child enjoy academic challenge? The SET schools attract highly motivated, academically confident peers. Children who thrive in that environment tend to be those who genuinely enjoy learning, are comfortable with competition, and can handle the pressure of high expectations from both teachers and classmates. Children who prefer a less pressured pace, or who have broader strengths in practical, creative, or vocational areas, may flourish more in a different type of school.

How does your child respond to setbacks? At a super-selective school, even very able children will not always be top of the class. The peer group is exceptional across the board. A child who has always found school easy may encounter academic challenge for the first time and need to develop resilience. This can be a wonderful growth experience for the right child, but it can be stressful for a child who ties their sense of worth closely to always being ahead.

What are the practical logistics? The SET schools are located in or near Sutton. For families in central London or further into Surrey, the commute can be significant. A Year 7 child commuting 45 minutes each way on public transport faces a meaningfully different daily experience from a child whose school is a short walk or bus ride away. Factor travel time, cost, and independence into your thinking.

Are there strong alternative options? A child who narrowly misses the SET threshold is not without excellent secondary options. Good non-selective schools in Sutton, Merton, and surrounding boroughs offer strong outcomes, and some independent schools offer scholarships or bursaries for academically able children. It is important that SET preparation sits within a broader secondary school strategy, not as the only option being considered.

If the answers to these questions suggest a SET school is a good fit, then the investment in preparation makes clear sense. If there are doubts, it is worth widening the conversation to include other selective options such as the Consortium for Selective Education in Wandsworth, Tiffin Schools in Kingston, or grammar schools in neighbouring areas.

What Happens If Your Child Does Not Get a SET Place?

Not getting a SET place is a difficult experience, but it is one that thousands of families navigate every year. The important thing to remember is that the outcome says nothing fundamental about your child's potential. The SET is an extremely high bar, and many children who do not reach a qualifying score go on to have outstanding academic careers at other schools.

If the score is close to the threshold, it is worth checking the individual schools' waiting list procedures. Some SET schools operate ranked waiting lists, and movement does occur between results in October and school places being confirmed in March. Families who want to be considered for a waiting list position should contact the relevant school admissions team promptly after results are published.

If the score is significantly below the threshold, the right focus shifts to making the best possible choice from the remaining school options. Many families in this position find that a strong non-selective school, chosen carefully and with good pastoral support, turns out to be the best environment for their child. Academic outcomes at top comprehensive schools in the Sutton and Merton area are genuinely competitive.

Other selective options to consider include:

Tiffin School and Tiffin Girls' School in Kingston use a separate entrance test and have their own competitive process. A child who scores well enough for the SET threshold but does not receive a place due to distance factors, for example, may be competitive for Tiffin.

The Consortium for Selective Education (CSE) in Wandsworth covers Graveney School and other selective-stream arrangements in that borough.

Grammar schools in Surrey, including those in Reigate and Guildford, run their own tests and may be accessible to families in the southern parts of the SET catchment.

Independent schools in the area offer academic scholarships, and some have bursary programmes for families who cannot afford full fees. A child who prepared seriously for the SET is likely to be well-prepared for independent school entrance exams.

Finally, it is worth noting that secondary school is not the final selection point in a child's education. Children continue to develop, and sixth form college, A-level and beyond offer many routes to excellent outcomes regardless of which secondary school they attend.

Verbal Reasoning and Non-Verbal Reasoning: What to Expect

Because verbal reasoning and non-verbal reasoning are not standard parts of the primary school curriculum in England, many families are surprised to discover these papers form half of the SET. Understanding what each involves helps you prepare more effectively.

Verbal Reasoning question types in the SET include:

Word analogies: Completing a pattern such as "cold is to hot as dark is to ____". These test vocabulary and the ability to recognise relationships between words.

Letter codes: Deciphering a coded alphabet to identify a hidden word or complete a sequence. These reward logical thinking and the ability to apply a rule systematically.

Hidden words: Finding a word hidden at the boundary between two words in a sentence, for example "I want a photograph" contains the hidden word "toga".

Compound words: Identifying a word that can be added to two given words to form compound words, testing vocabulary and word construction knowledge.

Number series in word form: Some VR questions include numerical sequences presented using letter-number coding. These straddle the boundary between verbal reasoning and pattern recognition.

Non-Verbal Reasoning question types include:

Sequences: Identifying which shape comes next in a series, requiring the child to spot one or more rules governing how the sequence changes.

Matrices: A grid of shapes where one cell is missing, and the child must identify the rule and select the correct answer.

Odd one out: Five shapes are presented and the child identifies which one does not share the property common to the other four.

Reflection and rotation: Identifying how a shape would look if reflected or rotated, testing spatial reasoning.

Nets: Identifying which 2D net would fold to make a given 3D shape.

For both VR and NVR, the most effective preparation combines initial teaching of each question type, followed by timed practice papers, followed by careful error analysis. Children who understand why they got an answer wrong learn much faster than those who simply re-sit papers without reflection.

Understanding Standardised Age Scores (SAS)

The SET results are reported as Standardised Age Scores rather than raw marks. This adjustment is important and frequently misunderstood by parents.

A raw mark is simply the number of questions answered correctly. A standardised age score takes that raw mark and adjusts it based on the child's age at the time of sitting the test. Because the test is sat in September of Year 6, children in the same cohort can differ in age by up to eleven months. A child born in September is nearly a full year older than a child born in August of the same school year. Without age standardisation, the older children would have a systematic advantage.

The standardisation process converts raw marks to a scale where 100 represents the average for the age group nationally, and the scores are distributed with a standard deviation of approximately 15 points. This means:

• A score of 100 is exactly average for the national age group
• A score of 115 is one standard deviation above average, placing the child in approximately the top 7 percent
• A score of 118 is roughly the top 4 percent
• A score of 121 or above is in approximately the top 2 percent
• A score of 130 represents exceptional performance, in the top 0.1 percent or so

The maximum possible SAS is typically 140 or 141, though very few children approach this ceiling.

For parents monitoring preparation progress through mock exams, it is worth noting that mock exam providers use their own standardisation models which may differ slightly from the actual GL Assessment standardisation. A score of 120 on one mock paper provider's test is not necessarily equivalent to a 120 on the real SET. Use mock scores as directional guidance and monitor trends over time rather than treating any single mock score as a definitive prediction.

One additional point: because the SAS adjusts for age, a summer-born child who seems behind their peers during Year 5 may score comparably on the standardised test once the age adjustment is applied. Parents of summer-born children sometimes underestimate their child's potential SET performance for this reason.

The Role of Primary School in SET Preparation

SET preparation is primarily a family and private tuition responsibility rather than a primary school one. State primary schools in England are not resourced to deliver SET-specific preparation, and most class teachers are focused on National Curriculum delivery and SATs outcomes rather than selective entrance exam preparation.

That said, a strong primary school education is the foundation on which SET preparation builds. Children who are taught to read widely and critically, to approach mathematics with genuine understanding rather than rote procedure, and to think logically and independently are far better placed to benefit from focused SET preparation than those who lack those foundations.

Parents can support primary school learning in several ways. Encouraging independent reading of challenging fiction and non-fiction (not just age-rated books) builds vocabulary and comprehension skills that transfer directly to the English and verbal reasoning papers. Playing logic games, puzzles, and strategy games develops the spatial and sequential thinking that underpins non-verbal reasoning. Practising mental arithmetic regularly, even informally, maintains the number fluency that the Maths paper demands.

Some families engage a private tutor to supplement school learning during Years 4 and 5. Others use structured online preparation programmes. Both can be effective if they are used intelligently: the goal is genuine skill development, not the ability to recognise a test question format without understanding the underlying concept. A child who has learned to guess VR answers from pattern recognition without understanding why is vulnerable in the exam when a question is presented slightly differently.

Communication with the class teacher can also be valuable. A good primary school teacher will know the child well and can offer honest guidance on whether the child is ready for the SET level of challenge. They may also be able to signal if there are learning or confidence issues that would benefit from additional support before embarking on intensive 11-plus preparation.
