Grammar School Preparation: The Complete Parent's Guide 2026

Grammar school preparation in 2026 requires a structured, school-specific plan beginning as early as Year 4. The 11 Plus is not a single national exam: each school or area chooses its own test. Kent and Buckinghamshire include verbal and non-verbal reasoning, while the Essex CSSE tests only English and maths. This guide covers when to start, what each test asks, how competitive schools are and how to prepare.

What Are Grammar Schools and How Does Selective Entry Work?

Grammar schools are state-funded secondary schools that select all or most of their pupils by academic ability. Entry is determined by performance in the 11 Plus examination, typically sat in Year 6 during September or October of the application year.

The selective admissions process works in parallel with the standard state school application. Parents register their child for the 11+ test, with registration usually closing between mid-May and the end of July of Year 5 (Reading School's closed on 17 May 2026, Buckinghamshire's on 2 June 2026, the CSSE's on 19 June 2026 and the Sutton SET's on 31 July 2026; The Tiffin Girls' School's stayed open until noon on 1 September 2026); the child usually sits the test in September or early October of Year 6 (Reading School tested in July of Year 5 for 2027 entry); most results arrive before parents submit their Common Application Form (CAF) to their local authority by the closing date (Saturday 31 October 2026 for Birmingham, Buckinghamshire, The Tiffin Girls' School and the CSSE schools; Monday 2 November 2026 in Kent), although the second stages at Tiffin School and The Tiffin Girls' School fall in November. Kent Test results day is Thursday 15 October 2026, Buckinghamshire's results were released on 9 October 2026 and the CSSE's are emailed after the close of business on 12 October 2026. School offers are made on National Offer Day, 1 March 2027. Missing a deadline can cost a place, because many schools take no late registrations.

Reaching a grammar school's test standard is only the first step, because schools choose between qualifying children in different ways. The Tiffin Girls' School gives priority to girls living in its catchment area; Kendrick School in Reading advises families outside its designated area not to register, because no such candidate has been offered a place since 2013; and Wilson's keeps 14 places for boys eligible for free school meals and 9 each for sport and music aptitude. Some schools also reserve places for aptitude: Dame Alice Owen's School in Potters Bar admits children under both academic and music aptitude criteria, and Reading School reserves 10% of places for boys who show both academic ability and sporting aptitude.

GL Assessment, CEM or the School's Own Test: Which Does Your Target School Use?

Understanding which test your target school uses is the single most important piece of research before buying a single practice paper. Formats differ sharply from school to school, and mixing up preparation resources is one of the most common and costly mistakes families make.

GL Assessment supplies papers to several grammar schools. It produces Buckinghamshire's Secondary Transfer Test, two papers of about 60 minutes each measuring verbal, mathematical and non-verbal skills, and Buckinghamshire gives every child the chance to work through a familiarisation booklet and try the question types. GL also marks and standardises Kendrick School's two papers in Reading and, for 2027 entry, provides the verbal reasoning paper at Dame Alice Owen's School, while The Latymer School moves to Quest Assessments from September 2027, for 2028 entry.

CEM, the Centre for Evaluation and Monitoring, sells Cambridge Select Insight, which it says is designed for selective independent schools, partially selective state schools and grammar schools. It is a computer-based assessment that schools buy individually, suitable for 11+, 13+, late transfer and fair banding, and no practice or past papers are sold for it. Check what your target school actually uses before buying anything labelled CEM-style.

A third answer is that neither applies. Many state grammar schools run their own tests or share one with neighbouring schools: Tiffin School works with Quest to set its own test, The Tiffin Girls' School runs a two-stage test, Queen Elizabeth's School in Barnet runs its own entrance test, Reading School uses the FSCE test, and the Sutton SET and the Essex CSSE are shared tests. Independent schools have their own admissions processes too — our RGS Guildford 11+ preparation guide sets out what one such school's assessments ask for.

See our detailed breakdown in the CEM vs GL Assessment Complete Parent Guide 2026, or book a free consultation and we will confirm which tests your child's target schools use.

When Should Grammar School Preparation Start? Year-by-Year Timeline

The right start date depends on how competitive the target school is and where the child is academically. Here is a practical timeline:

Year 3 (age 7–8): Build strong foundations in maths and English through school and reading. No formal 11+ preparation needed yet. Focus on rapid mental arithmetic, wide reading habits, and times tables to 12×12.

Year 4 (age 8–9): Recommended start for children targeting super-selective London schools (Henrietta Barnett, Tiffin, Queen Elizabeth's, Wilson's and the other Sutton grammar schools). Begin with topic-by-topic maths and English, and add verbal reasoning only if the target school tests it: Henrietta Barnett's Round One does, but Queen Elizabeth's and the Essex CSSE do not. Aim for one or two sessions per week. A good tutor at this stage focuses on depth of understanding, not test-taking speed.

Year 5 (age 9–10): Appropriate start for most county grammar schools. Begin bridging from core skills to timed practice. Introduce non-verbal reasoning if the target test includes it, as the Kent and Buckinghamshire tests do, and build vocabulary. By the summer of Year 5, children should be doing regular timed sections.

Year 6 (age 10–11, tests in September or October): Intensive preparation phase. Children should be doing full timed mock papers under exam conditions regularly from May of Year 5 onwards. Identify weak areas and target them specifically. Exam technique — question order, time management, checking — becomes critical. Most tests fall in September: for 2027 entry, the Kent Test was on 10 September 2026 for children at Kent primary schools, Buckinghamshire's Secondary Transfer Test on 10 September 2026 (after a practice test on 8 September), the Sutton SET on 15 September and the CSSE on Saturday 19 September 2026, while Tiffin School's Stage One was held on 2 October 2026 and The Tiffin Girls' School's on 1 and 2 October 2026.

What Does the 11 Plus Actually Test?

The 11+ draws on up to four skill areas, and each test uses a different mix: the Kent Test covers all four, while Queen Elizabeth's in Barnet and the Essex CSSE test only mathematics and English.

Verbal Reasoning: This tests a child's ability to work with words and language logically — anagrams, synonyms, antonyms, letter and word codes, analogies, and comprehension. Strong reading habits from an early age build this naturally. Our Eleven Plus Verbal Reasoning Complete Parent Guide covers every question type in detail.

Non-Verbal Reasoning: This assesses spatial and pattern-based thinking — identifying shapes that complete a series, finding the odd one out, rotating figures, and folding nets. Familiarity with the question types matters a great deal here, so regular practice helps, but only where the target test includes non-verbal reasoning. See our Non-Verbal Reasoning guide.

Mathematics: 11+ maths covers the standard KS2 curriculum but demands speed and accuracy well above average classroom level. Topics include fractions, decimals, percentages, ratio, algebra, area and perimeter, data handling, and word problems. See the full topic checklist at Eleven Plus Maths Topics: Complete Checklist.

English / Comprehension: Most tests include reading comprehension, and several add written work: Dame Alice Owen's English paper is a one-hour comprehension paper that includes an extended writing piece. The Kent Test's writing exercise is not marked, but a headteacher panel may use it. See our guide on Eleven Plus English Comprehension: Question Types and Mark Schemes.

How Competitive Is the 11 Plus? Statistics by School and Region

The 11+ is not uniformly competitive — the qualifying standard and the way places are offered differ from area to area and school to school. Understanding real competition levels helps families set realistic expectations.

Henrietta Barnett School has 120 Year 7 places for 2027 entry and invites the top 300 candidates from Round One to Round Two; Queen Elizabeth's School, Barnet, usually holds its tests over two days in September; and Dame Alice Owen's School invites the top 325 from its Part I verbal reasoning test to Part II. The two Tiffin schools admit separately: each runs a Stage One test and invites only some children to a Stage Two test, on 12 November 2026 at Tiffin School and 7 November 2026 at The Tiffin Girls' School. In Sutton, the shared Selective Eligibility Test (SET) was held on 15 September 2026, with second stages held on 26 September 2026 for Nonsuch High School for Girls and Wallington High School for Girls and on Saturday 3 October 2026 for Wilson's School, Wallington County Grammar School and Sutton Grammar School.

By contrast, Kent sets a qualifying standard. Kent County Council says its grammar schools provide for about the top 25% of the ability range. It also says many children will find the Kent Test difficult and suggests discussing a child's academic achievement with their primary school before registering. Buckinghamshire expects about 37% of children to reach its qualifying score of 121. Reaching the standard is not the same as winning a place at a popular school: The Judd School in Tonbridge, which publishes cut-off scores by area, had an Inner Area cut-off of 389 for 2026 entry (403 for the Outer Area) against Kent's 2025 threshold of 332.

There is no single national pass rate, because each area and school sets its own standard. See our detailed analysis at Eleven Plus Pass Marks by Region: How High Do You Need to Score?

London Super-Selectives vs County Grammars: Different Strategies Required

These two categories require fundamentally different preparation approaches. Treating them the same is a strategic mistake.

Among London super-selectives, Henrietta Barnett, Queen Elizabeth's and Tiffin School each run their own entrance tests, while the Sutton grammar schools share a first-stage test, the SET. At Henrietta Barnett, the top 300 candidates from Round One (verbal reasoning, non-verbal reasoning and English) are invited to Round Two in English and maths, which was held on Tuesday 6 October 2026. Preparation at this level demands not just correct answers but speed, consistency, and the ability to perform under pressure. Mock exams under timed conditions, ideally graded with proper standardisation, are essential. At Queen Elizabeth's, a boy needs a combined score of 225 to be eligible to be considered for admission. See our guide to London Super-Selective Grammar Schools.

County grammar areas set a qualifying standard instead. In Buckinghamshire a score of 121 or more qualifies, and once a child qualifies the score plays no further part, because places are allocated by each school's own admission rules; in Kent, the 2025 threshold was a total of 332 with no single score below 108. The preparation emphasis shifts from extreme speed to reliable accuracy across every paper. Many children preparing for county grammars in Kent or Buckinghamshire will benefit from structured preparation, but not at the intensive pace required for London super-selectives.

The Latymer School, Henrietta Barnett and Queen Elizabeth's each run their own tests: for 2027 entry, Henrietta Barnett's Round One ran on 2 to 4 September 2026 and Latymer's tests on 3 to 5 September; Queen Elizabeth's usually holds its tests over two days in September. Where schools do share a test, as the Sutton SET schools do, each school or group of schools then runs its own second stage — see our guide to schools that share an 11+ paper for how offers are decided when several schools use the same test.

What Good Grammar School Preparation Looks Like

Effective preparation is not about volume of papers — it is about deliberate practice with intelligent feedback. Here is what our experience preparing children for selective schools suggests:

Structured topic work before timed papers. Many families go straight to practice papers, which reveals weaknesses but does not fix them. Start with topic-by-topic mastery — mental arithmetic speed, vocabulary building, non-verbal reasoning question types — before introducing timed pressure.

Timed mock tests under exam conditions. From around May of Year 5, about four months before a September test, regular full timed mocks are essential. These develop time management, reduce test anxiety, and build stamina. Children should sit mocks in a quiet room, with no interruptions, and under proper time pressure. See our guide to how to practise filling in bubble answer sheets — a frequently overlooked exam technique issue.

Error analysis after every paper. Working through mistakes systematically — not just marking, but understanding why errors occurred — is where the learning happens. A child who sits many untimed practice papers and never analyses errors learns less than a child who sits fewer timed papers and reviews every wrong answer carefully.

One-to-one tuition for targeted support. A good tutor identifies the specific weaknesses holding a child back and designs sessions around fixing them. At Leading Tuition, our 11+ specialists use the first session to establish a baseline across all tested areas and build a preparation plan from there. In the 2025 admissions cycle, 38 of the 40 students we worked with at 11 plus and 13 plus (95%) received at least one offer from a selective or independent school.

Grammar School Catchment Areas and Designated Zones

Passing the 11+ does not guarantee a place at a grammar school if you live outside its designated or priority area. Many grammar schools use distance-from-school tiebreakers or have formal designated areas that give priority to residents within a specific postcode zone.

Henrietta Barnett School publishes its Admissions Policy 2027-2028 and Admission FAQs on its admissions page. See our Henrietta Barnett admissions area guide for more on its area rules.

The Tiffin Girls' School gives priority to girls in its Designated Area of 44 postcode districts, and since 2014 all its places have gone to girls living inside it. In Sutton, Wilson's uses Sutton residence only to separate tied scores.
