Kent is unusual. Most of England operates a mixed secondary system where grammar schools are the exception. Kent kept selective education across the entire county. All 33 grammar schools in Kent select by the same test, on the same day, at the same time of year. If your child lives in Kent and grammar school is on the table, understanding how this works is the first thing to get right.
What is the Kent Test?
The Kent Test is the single entry point for all grammar school places in the county. It's administered by GL Assessment and taken in early September of Year 6. That's unusually early. Most 11+ areas test in September too, but Kent sits among the earliest, often in the first full week of the autumn term.
Children who live in Kent are automatically registered for the Kent Test through their primary school. If you live outside Kent but want your child considered for a Kent grammar school, you need to register separately through the KentChoices4u admissions portal. The deadline for out-of-county registration is usually in June of Year 5, so it catches parents off guard if they haven't planned ahead.
The test itself covers three areas: English, Maths, and Reasoning. The English section includes reading comprehension, punctuation, spelling and grammar. Maths covers the primary curriculum up to and including Year 6 content. Reasoning tests both verbal and non-verbal reasoning in the GL Assessment style, the same format used in most of Essex, Buckinghamshire, and parts of Lincolnshire.
Why does Kent test in September?
The short answer: because it needs to. Grammar school applications in Kent are made through the normal Kent admissions process with a secondary school preference deadline in October. Test results need to be out before that. That means sitting the test at the start of Year 6, not the end of Year 5.
For parents, this is a significant planning point. Your child has roughly the summer between Year 5 and Year 6 as final preparation time. Any heavy lifting needs to be done before September arrives. There's no grace period. Children turn up for the Kent Test a fortnight into the new school year.
What does passing the Kent Test actually mean?
A pass on the Kent Test means your child has been assessed as suitable for grammar school education in Kent. It doesn't guarantee a place at any specific school. That's determined separately by the normal admissions criteria (distance, siblings, religion where applicable). But without a pass, a child cannot be offered a place at a Kent grammar school.
The pass mark is standardised each year. It isn't a fixed percentage score. GL Assessment calculates an age-standardised score for each child, which adjusts slightly for when in the school year they were born. Summer-born children don't get a different pass mark. But the standardisation process accounts for the age gap. A child born in August is nearly a year younger than a child born in September, and that's factored in.
Kent publishes the pass mark after the test. In most years it sits around the 320–330 range out of a maximum standardised score in the high 300s, but it shifts. Don't treat any specific number as gospel until the year's results are released.
The borderline review
Kent has a formal borderline review process, which not every area offers. Children whose scores fall within a defined range just below the pass mark are automatically reviewed. Schools can request to see a teacher assessment form, and primary schools submit a written assessment of a child's academic ability.
This isn't a soft second chance for everyone. The borderline band is narrow. Children well below the pass mark aren't included. But for children who sit right on the edge, a strong primary school assessment can tip the balance. Make sure your child's primary school understands that you want the assessment completed carefully if it becomes relevant.
Some parents assume the borderline review is something they push for. It isn't. The process runs automatically based on score. What you can do is ensure the primary teacher knows the context and takes the assessment seriously.
Grammar schools in Kent: not all the same
There are 33 grammar schools in Kent. That sounds like a lot of choice, but the schools vary considerably in location, character, and competition for places. Tonbridge and the surrounding area has some of the most sought-after schools in the county. The Judd School in Tonbridge and Tonbridge Grammar School for Girls both attract strong demand. Harvey Grammar School in Folkestone, Simon Langton Grammar School for Boys in Canterbury, and Maidstone Grammar School are other well-regarded options.
Distance tends to determine where you realistically apply. Most Kent grammar schools prioritise children who live closest, so applying to Judd from the Medway Towns is unlikely to result in a place even with a strong pass. Know your catchment before you get attached to a specific school.
Kent doesn't have a single super-selective tier in the way some other counties do. A pass is a pass. Some schools fill quickly because of location and reputation, but the selection threshold is the same Kent Test for all of them.
How to prepare
The Kent Test format is GL Assessment, which is the most thoroughly practised exam type in the country. Good practice materials are easy to find. CGP and Bond publish full practice paper sets specifically matched to GL format. The question types in verbal reasoning, non-verbal reasoning, English, and maths are all learnable with consistent work.
The timeline that works for most Kent families is to start structured practice in January or February of Year 5, build familiarity with the question types through spring, do regular timed work across the summer, and use August for full mock papers in exam conditions. By the time September arrives, the test should feel familiar rather than frightening.
What trips children up most in Kent is the timing pressure of the verbal and non-verbal reasoning sections. GL papers move fast. A child who understands the methods but works slowly will still drop marks. Timed practice needs to be part of preparation from at least Easter of Year 5 onwards — not something you add in August and hope sticks.
English catches some children out because it requires more than reading comprehension. Punctuation and grammar questions test technical knowledge that some Year 5 and 6 children haven't consolidated well. It's worth doing specific work on that, not just reading widely and hoping it absorbs.
Maths up to Year 6 is the expectation. That means fractions, percentages, ratio, area and perimeter, basic algebra, and data handling. Children who are strong at maths often find this the most comfortable section. Children who struggle with maths need early attention here because it's the section least helped by last-minute practice.
What about tutors?
Kent has a substantial tutoring industry and plenty of children sit the Kent Test with at least some tutoring behind them. Is it necessary? It depends on your child and your family. A good tutor helps most in identifying and filling specific gaps in the months before the test. General weekly tutoring from Year 4 onwards is probably more about parental anxiety than genuine exam benefit.
If your child is near the borderline, targeted preparation in the final six months can make a real difference. If they're comfortably above it after a mock test in the spring, the marginal return on additional tutoring is low. The honest question is whether you're doing it for the child or for yourself.
FAQ
My child is in Year 5 and we're just starting to think about this. Are we too late?
No. Starting structured preparation in Year 5 is exactly the right time. Most Kent families begin in January or February of Year 5. You have roughly 12 to 18 months, which is enough to cover the material without burning your child out. What you don't want to do is leave it until the summer before the test and try to cram everything into six weeks.
Can children from outside Kent sit the Kent Test?
Yes. Out-of-county children can register and sit the Kent Test. You register through the KentChoices4u portal, and the registration deadline is usually in June of Year 5. If you miss it, contact Kent County Council directly. Late registrations are sometimes possible, but not guaranteed. Out-of-county children who pass still apply through the normal admissions process and compete for the same places.
Does the September sitting date mean my child is sitting the test without much Year 6 learning under their belt?
Effectively yes. The test happens within the first couple of weeks of Year 6, so your child is being tested mainly on what they've learned by the end of Year 5 and whatever they've done over the summer. This is why the summer before Year 6 matters so much in Kent. Schools don't explicitly teach to the test over Year 5, so most preparation happens at home.
How do borderline scores get treated if my child applies to multiple Kent grammar schools?
The borderline review is run once at the county level, not school by school. If your child is in the borderline band, one review process runs. The outcome applies to their general Kent Test result, not to specific schools. Individual schools don't run their own secondary reviews on top of the Kent borderline process.
