If Maidstone Grammar School is on your child's list, preparation should be shaped around how this school actually selects — not generic 11+ advice. MGS admits boys through the standard Kent Test, so the smartest plan is to practise the exact subjects, question types and timing that the Kent Test uses, then rehearse them under real conditions until they feel routine. This guide walks through the school, the test, what to practise, a build-up timeline, and how to keep your child calm on the day — with links to free Quest Arena worksheets and mocks for every skill named.
About Maidstone Grammar School
Founded in the mid-16th century by Edward VI, Maidstone Grammar School (MGS) is one of Kent's most over-subscribed grammars. It is a boys' grammar with a mixed sixth form, and selection is by the standard Kent Test rather than any bespoke school paper. Because places are heavily contested, a qualifying score is only the first step — securing a place also depends on the school's admissions criteria, so read the current policy carefully on the school's own site each year.
- Location: Maidstone, Kent
- Intake: Boys (Mixed Sixth Form)
- Founded: 1549
- Type: Academy Grammar
- Admissions test: Kent Test (GL Assessment)
You can read the full school profile on Quest Arena, and always confirm this year's admissions policy, catchment rules and open-day dates on the official Maidstone Grammar School website. MGS sits within Kent's system of 32 state grammar schools — England's largest fully-selective network — which is browsable in our grammar school directory.
How selection works at Maidstone Grammar School
Entry to MGS is decided by the Kent Test, produced by GL Assessment and sat by children across Kent in early September of Year 6 — right at the start of the autumn term, before applications are finalised. This is the single most important point in the timeline to get right: the test happens in September of Year 6, so all the practice must be finished before the summer holidays end.
The Kent Test is made up of separately-timed, multiple-choice papers covering three areas:
- English — a comprehension-led paper testing reading understanding, spelling, punctuation and grammar.
- Maths — Key Stage 2 arithmetic and problem-solving, worked at pace and without a calculator.
- Reasoning — a combined paper covering Verbal Reasoning (VR) and Non-Verbal Reasoning (NVR).
Answers are marked on a separate answer sheet, and the raw marks are converted into age-standardised scores so that younger, summer-born children are not disadvantaged. Kent then combines the standardised scores across the papers into an aggregate, and a child is assessed against both an overall threshold and a rule that no single area falls too low. To show how that works in practice — without quoting any figure as this school's guaranteed cut-off — imagine a scheme where a child needs an aggregate of 320 across the three areas with none below 106. A boy scoring 116 (English), 108 (Maths) and 110 (Reasoning) reaches 334 with every area above the floor, so he qualifies. A boy scoring 130, 118 and 102 totals 350 but is held back by the 102 in Reasoning. The lesson is simple: strengthen the weakest area, because a very high score elsewhere cannot rescue a low one. Exact thresholds are set by Kent each year and are published officially, so never rely on a number you have seen quoted second-hand.
Children who narrowly miss the qualifying standard can usually be considered through a head-teacher assessment or local appeals route; the details live in Kent's admissions guidance and on the school site.
What to practise for this test
Because the Kent Test is a GL Assessment product, it is one of the most learnable 11+ formats: the question types are published, stable and predictable, so systematic type-by-type practice pays off directly. Focus on four skill areas and drill each until it is automatic.
- English & comprehension: reading a passage closely, inferring meaning, and answering fixed-format questions quickly. Wide vocabulary is the single best predictor of both comprehension and verbal-reasoning marks, so build it daily.
- Maths: fluent times tables, fractions, percentages, ratio, and multi-step word problems — all at roughly a minute per question. Speed and accuracy matter equally.
- Verbal Reasoning: around 21 named GL question types, including letter and number series, hidden words, letter codes, analogies, closest-meaning and opposite pairs, compound words, odd-one-out and move-a-letter. For example, in a code question, if CAT is written as DBU, each letter has moved on by one, so DOG becomes EPH.
- Non-Verbal Reasoning: series, matrices, analogies, odd-one-out, reflections, rotations and cube nets/folding — spotting the visual rule (a shape rotating 90 degrees, a pattern reflecting, a net folding into a cube) and applying it.
Start with our GL Assessment practice papers, all free, then use the free worksheet library to strengthen whichever subject a first timed paper exposes as weakest. When your child can handle single question types confidently, move to full-length timed mock papers, and in the final weeks switch to centre-specific mocks matched to the Kent format. No account is needed to start practising.
A realistic preparation timeline
The most effective preparation is spread over two years of gentle habit-building rather than crammed into a panicked summer. Because the Kent Test falls in September of Year 6, the real deadline is the end of the Year 5 summer holiday.
- Year 4 into the summer: daily reading of varied, slightly challenging books; times tables to 12×12; short mental-maths games. No formal papers yet — the goal is a strong, curious reader who enjoys number puzzles.
- Year 5 autumn: begin 15–20 minutes of daily topic practice with our free worksheets, introducing verbal and non-verbal reasoning gradually alongside English and maths.
- Year 5 spring: register in good time. Kent's registration window for the September test typically opens in the early summer and closes before the holidays — check the exact dates on our key dates page and confirm on the school's own site.
- Year 5 summer: one full timed mock paper a week. Review the mistakes far more carefully than the score — every wrong answer is a lesson for the real thing.
- Final few weeks before September: switch to centre-specific papers in the Kent format so the layout, answer sheet and timing feel completely familiar.
Keep sessions short and consistent. Twenty focused minutes a day beats a three-hour weekend marathon, and it protects your child's enthusiasm — which matters as much as any single mark.
On the day and after
By test day the aim is for the exam hall to feel like the eleventh time, not the first. A child who has sat ten timed mocks at the kitchen table treats the real thing as routine, and calm composure is often what separates candidates at the margin.
- The night before: pack pencils, a rubber and anything the school asks for, lay out uniform, and get an early night. Do no new practice — it only raises nerves.
- On the morning: a proper breakfast, arrive with time to spare, and keep the mood light. Remind your child of one strategy, not ten: if a question is stuck, mark your best guess and move on.
- During the paper: watch the clock, don't linger on any single question, and check the answer sheet number matches the question number.
- Afterwards: praise the effort regardless of how it felt, and avoid post-mortems. Results are released by Kent in the autumn, in time for the secondary application deadline, so use the intervening weeks to keep reading and stay relaxed.
Whatever the outcome, the reading, reasoning and resilience your child builds are worth having in their own right — and every resource to build them is free on Quest Arena.
Frequently asked questions
Is the Maidstone Grammar School test GL or CEM?
It is the Kent Test, produced by GL Assessment. CEM's separate paper 11+ was discontinued around 2023, and Kent uses GL-style multiple-choice papers, which are predictable and reward type-by-type practice.
When is the Kent Test sat?
In early September of Year 6, at the very start of the autumn term. Registration opens earlier, usually in the early summer of Year 5, so confirm the exact window on the school's official site and our key dates page.
What subjects does the Kent Test cover?
English (comprehension, spelling, punctuation and grammar), Maths (Key Stage 2 problem-solving without a calculator), and a Reasoning paper combining Verbal and Non-Verbal Reasoning. Scores are age-standardised and combined into an aggregate.
