Practical guidance from the Leading Tuition team
Book a Free ConsultationKent is home to more grammar schools than any other county in England, with over 30 selective state schools offering strong academic results and well-resourced sixth forms. The best grammar schools in Kent — including Tonbridge Grammar School, Judd School, Dartford Grammar School, and Simon Langton Grammar School for Boys — consistently rank among the top state schools nationally, with outstanding Ofsted ratings and A-level results that rival independent schools. Choosing the right one depends on your child's strengths, your location, and how competitive the admissions process is in your area.
Kent operates a fully selective secondary system, meaning the 11-plus (also called the Kent Test) is the gateway to all grammar school places. Children in Year 6 sit the Kent Test in September, typically at age 10 or 11, and results determine whether they are deemed "suitable for grammar school education." This is different from many other selective areas where grammar schools exist alongside non-selective comprehensives — in Kent, secondary modern schools serve those who do not pass or do not sit the test.
The Kent Test is set by GL Assessment and covers reasoning (verbal, non-verbal, and spatial) as well as English and maths. Scores are standardised by age, so a child born in September is not automatically advantaged over one born in August. Parents can register their child for the test through Kent County Council, and the deadline typically falls in June of Year 6.
It is worth knowing that grammar schools in Kent are still state-funded — there are no fees. However, competition for places at the most sought-after schools is fierce, and many families invest in 11-plus preparation well in advance.
While every grammar school in Kent is selective, there is a clear tier of schools that attract the most applications and produce the strongest outcomes at GCSE and A-level.
Tonbridge Grammar School is an all-girls school consistently rated Outstanding by Ofsted. It regularly achieves among the highest Progress 8 scores in the county and has an excellent sixth form with strong uptake in sciences and humanities at A-level.
The Judd School in Tonbridge is an all-boys grammar with a national reputation. It frequently appears in league tables for A-level performance and has produced a notable number of Oxbridge entrants. Entry is highly competitive, and the school draws applicants from across the Tonbridge and Malling district.
Dartford Grammar School (boys) and Dartford Grammar School for Girls are both rated Outstanding and serve the north-west of the county. Their proximity to London makes them popular with families in the Dartford and Gravesham areas.
Simon Langton Grammar School for Boys in Canterbury is well regarded for its sixth form and extracurricular offer, including a strong music and drama tradition. Simon Langton Girls' Grammar School is equally well regarded and sits nearby.
Maidstone Grammar School and Invicta Grammar School (girls, Maidstone) serve the county town and are both consistently high-performing, with strong GCSE and A-level results across core subjects including English Literature, Mathematics, and the sciences.
League table position is only one measure. When assessing which grammar school suits your child, consider the following:
One widespread misconception is that passing the Kent Test guarantees a place at your preferred grammar school. It does not. Passing means your child is assessed as suitable for grammar education, but individual schools then rank applicants using their own oversubscription criteria — typically distance, siblings already at the school, and in some cases, looked-after children. A child who passes the test but lives far from a popular school may not receive an offer there.
Another misconception is that tutoring is unnecessary or unfair. In practice, the majority of children who sit the Kent Test have had some preparation. This does not mean intensive coaching from Year 4 is required, but familiarising your child with the test format — particularly the non-verbal and spatial reasoning sections — is sensible and widely done.
Finally, some parents assume that grammar schools in Kent follow a different GCSE exam board from other schools. They do not. Kent grammar schools use the same national GCSE qualifications — predominantly AQA, Edexcel, and OCR — and sit the same exams as all other state schools in England. The difference lies in the pace and depth of teaching, not the qualification itself.
The process runs on a fixed annual timetable. Registration for the Kent Test opens in the spring term of Year 5 and closes in June of Year 6. The test itself takes place in September of Year 6. Results are sent to parents in October, and the standard secondary school application deadline (via Kent County Council's online system) falls on 31 October each year.
If your child is not initially assessed as suitable for grammar school education, you can request a review. This is a formal process where the school or Kent County Council re-examines the scores. It is not a re-sit, but it can occasionally result in a changed outcome if there were mitigating circumstances — illness on the day, for example.
Out-of-county applicants can also sit the Kent Test, and some grammar schools — particularly those near the borders with London, Surrey, or East Sussex — receive significant numbers of applications from outside Kent. Leading Tuition works with families across the South East preparing for the Kent Test and other selective admissions processes.
Which is the best grammar school in Kent overall?
There is no single answer, as "best" depends on your child's needs and your location. The Judd School and Tonbridge Grammar School are frequently cited for academic outcomes and Oxbridge entry. Dartford Grammar schools are strong choices for families in north-west Kent. Maidstone Grammar and Invicta Grammar are excellent options in the county town. Ofsted ratings, Progress 8 scores, and sixth form results are all worth comparing directly on the DfE's school performance tables.
Do you have to live in Kent to apply to a Kent grammar school?
No. Out-of-county children can sit the Kent Test and apply to Kent grammar schools. However, most schools prioritise applicants by distance after the selective threshold is met, so living further away reduces your chances at oversubscribed schools. Some schools near the Greater London border — such as those in Dartford — receive many applications from London-based families.
What score do you need to pass the Kent Test?
Kent County Council does not publish a fixed pass mark. Instead, children are assessed as either "suitable" or "not yet suitable" for grammar school education based on their standardised scores across the test's components. The threshold varies slightly each year depending on cohort performance. Preparation that builds genuine reasoning and literacy skills — rather than drilling to a specific number — is the most reliable approach.
Can a child sit the Kent Test if they attend a school outside Kent?
Yes. Any child in Year 6 can register for the Kent Test regardless of which school they currently attend or which county they live in. Parents register directly through Kent County Council's admissions portal. The test is the same for all children, and out-of-county applicants are assessed on identical criteria.
Choosing a grammar school in Kent is a significant decision, and the county's selective system gives families a genuinely wide range of high-performing options. Taking time to visit schools, review their sixth form and GCSE results on the DfE performance tables, and understand the admissions geography for each school will put you in a much stronger position than relying on reputation alone. Leading Tuition can help your child prepare thoroughly for the Kent Test with structured, age-appropriate support.
