Reading 11+ Test 2027: Berkshire Grammar School Preparation Guide
· 10 min read
Everything Reading and Berkshire parents need to know about Kendrick School, Reading School, and the wider Berkshire grammar consortium — formats, dates, and how to prepare for the most competitive 11+ in England.
The short answer
Reading is home to two of the most academically selective grammar schools in England — Kendrick School (girls') and Reading School (boys'). Both are super-selective: they admit purely on test rank, with no catchment area, and routinely receive five to ten applicants for every place. Kendrick uses a two-stage assessment: Stage 1 is a GL-style paper covering English, Maths, Verbal Reasoning, and Non-Verbal Reasoning in September of Year 6; Stage 2 is a written task (and historically an interview round in some years) for those who clear Stage 1. Reading School uses a single-stage test covering Maths and English. The wider Berkshire selective system also includes the Slough Consortium grammars — Herschel, Langley, Upton Court, and St Bernard's — plus Reading Boys and Kendrick. These schools test in different formats, mostly in September of Year 6. For the full regional breakdown, see our Reading 11+ region guide.
Kendrick School: a two-stage super-selective
Kendrick is unusual among English grammars in running a formal two-stage assessment. Stage 1 is a GL Assessment-style paper sat in September of Year 6, covering English (including comprehension), Mathematics, Verbal Reasoning, and Non-Verbal Reasoning. The exact balance and timing of the Stage 1 paper is published by the school each spring. Those who score above Kendrick's Stage 1 threshold are then invited to Stage 2, which historically has involved a written task — an extended writing exercise or comprehension response — and in some years an interview component. The written task assesses written fluency, structure, and depth of thinking in a way that a multiple-choice paper cannot. Children who pass Stage 1 on raw aptitude but have weak written English can fall short at Stage 2, which is why Kendrick preparation cannot stop at GL drill alone. Final offers are made on the combined Stage 1 and Stage 2 outcomes, with rank order determining places. Because Kendrick is a super-selective with no catchment, families apply from across Berkshire, Oxfordshire, Hampshire, and beyond. Effective qualifying scores at Stage 1 sit well above the typical grammar school threshold elsewhere — refer to the school's current published admissions guidance rather than historical figures.
Reading School: single paper, very high bar
Reading School (the boys' equivalent) runs a single-stage assessment, typically in September of Year 6. The paper covers Mathematics and English — Reading School does not formally test verbal or non-verbal reasoning as separate papers, though comprehension and problem-solving sections naturally incorporate reasoning skills. The format and length are published by the school each year. Like Kendrick, Reading School is super-selective: no catchment area, places allocated by rank order on the test. Competition is intense, with applicants regularly outnumbering places by five to one or more. Effective qualifying scores are very high, and there is little margin between qualifying and falling short. The practical implication is that Reading School preparation has to be deeper than reasoning-focused 11+ drilling. Strong Maths problem-solving — multi-step, worded, often requiring algebraic reasoning above expected Year 5 level — and confident written English comprehension are non-negotiable. Children who excel on GL reasoning papers but have only moderate Maths depth typically do not score competitively at Reading School.
The wider Berkshire and Slough consortium
Beyond Reading itself, the Slough Consortium covers four selective schools that operate a joint admissions test: Herschel Grammar School, Langley Grammar School, Upton Court Grammar School, and St Bernard's Catholic Grammar School. These schools use a single common test, with each school then applying its own oversubscription criteria on top of the qualifying score. Several families apply to both Reading (Kendrick or Reading School) and the Slough Consortium because the test windows are close enough to coordinate but the formats and qualifying thresholds differ. Children sitting both should plan for two preparation tracks: super-selective depth for Reading, and broader GL-style drill for the consortium. The Berkshire system as a whole is best understood as several parallel selective systems sharing geography rather than a single coordinated process. Always check each target school's current admissions arrangements rather than assuming a regional pattern. Our main 11+ overview lists the wider regional context if you're applying across more than one local authority.
Registration and key dates for 2027 entry
Reading's super-selectives use direct school registration, not local authority registration. Parents register their child with Kendrick and Reading School individually, via each school's admissions portal. Registration windows typically open in early summer 2026 and close before the September test sittings — exact deadlines are published on each school's admissions page in the spring. The Slough Consortium runs its own joint registration, separately from Kendrick and Reading. Stage 1 papers (Kendrick) and the Reading School test are typically in mid-September 2026. Stage 2 invitations for Kendrick are usually issued within a few weeks of Stage 1 results, with Stage 2 itself held in October or November. Final outcomes are typically communicated to parents before the 31 October 2026 secondary school application deadline, allowing families to confirm school preferences on the local authority's Common Application Form. National offer day is 1 March 2027. The practical sequence matters: if your child is sitting Reading and Slough Consortium tests, plus possibly an out-of-area test such as Sutton or Bucks, the September-October window can become very crowded. Plan the calendar in May, not August.
Why a Year 4 start matters more here than elsewhere
For most English grammar schools, starting structured 11+ preparation in the spring of Year 4 gives a comfortable preparation window. For Reading's super-selectives, that timeline is closer to the minimum than the ideal. The reason is depth. Kendrick and Reading School test at the upper end of what an able Year 6 child can reasonably do — Maths a year or more above expected level, comprehension well above expected reading age, written English with structure and voice. Building that depth genuinely (rather than drilling exam-shaped questions) takes time. A child who starts in Year 5 has roughly 12 months to do what Reading School-bound children in Year 4 have 18-24 months to do, and the time pressure shows in mock results. For a more general timeline that applies to most grammar regions, see our guide on when to start 11+ preparation. For Reading specifically, the recommendation is to add six months to that timeline. Late starts are not impossible, but they are uncommon among successful applicants. Parents considering Reading from Year 5 should be honest about the gap and prioritise daily reading, depth Maths, and written English from day one rather than spreading effort across all 11+ formats. GrammarPrep's diagnostic at grammarprep.uk/onboarding gives a starting benchmark across the four 11+ subjects, which is useful for identifying where the depth gap is largest.
How preparation differs from a single-paper region
Families moving from another region — or planning between Reading and somewhere like Kent or Trafford — often underestimate how much Kendrick's two-stage assessment changes preparation priorities. In a single-paper region, GL question-type fluency and timed multiple-choice technique are the dominant skills. A child who can rapidly identify and dispatch each of the ~21 GL verbal reasoning question types, with strong Maths fluency, will score well. The format is the format, and once mastered, raw practice volume produces gains. Kendrick's Stage 2 written task tests something different: written communication, structure, and depth of thinking. A child cannot drill their way to a strong written piece in the way they can drill their way to fluent code-breaking or shape rotations. What helps instead is sustained writing practice across Year 5 and the summer of Year 6 — short pieces, varied prompts, with feedback. Many families add a writing tutor or a structured writing curriculum specifically for Stage 2, on top of GL preparation for Stage 1. For a fuller comparison of the GL, CEM, and CSSE formats — and how Kendrick's Stage 1 fits into the GL family — see our exam boards comparison.
Out-of-catchment applications and realistic odds
Because Kendrick and Reading School are super-selective with no catchment, applications come from a wide geographic area. Families in Oxfordshire, Hampshire, west London, and along the Thames Valley regularly apply. There is no geographic disadvantage in eligibility — but there is a logistical one. Daily commutes from outside Berkshire can be long, and parents should be honest about whether the school is genuinely the right fit even if a place is offered. The odds of an offer are best understood not as a percentage but as a rank-order question. With five to ten applicants per place, your child needs to be in the top decile of test-takers — a cohort that is itself self-selecting at the top of national academic ability. Mock-paper performance at the typical regional grammar pass mark (around 80% on a Kent-style paper, for example) is well below what Reading's super-selectives require. Most families applying to Reading also apply to a wider safety net: the Slough Consortium, a non-selective state preference, and sometimes an independent school option. Pinning the entire secondary school plan on a Kendrick or Reading offer is high-risk even for very able children. The right approach is to prepare seriously for Reading while building a realistic backup, and to use tools like our free diagnostic and Reading region guide to track progress against the appropriate benchmark — not against a generic 11+ pass mark.
