When Should My Child Start 11+ Preparation? An Oxford Tutor's Realistic Timeline

Here's the thing families miss: you don't choose when 11+ preparation ends. The tests do. And they fall much earlier than most parents expect — for the grammar route, right at the start of Year 6, before your child has properly unpacked their new pencil case.

Near Oxford, the state grammar options sit their tests in September of Year 6. Buckinghamshire's Secondary Transfer Test is sat in early September at the very start of Year 6, with out-of-county registration back in May–June of Year 5. Kendrick School in Reading sat its 2027-entry test on Friday 18 September 2026, with registration having closed on 1 July 2026. Reading School's out-of-catchment day applicants sat on 25 September 2026. If the test is in September, then in practical terms Year 5 is your last full preparation year — the summer holiday before Year 6 is the final straight, not the starting line.

Oxford's leading independent day schools run to a slightly later, but still early, rhythm. Magdalen College School sits its 11+ entrance exam in January of Year 6 (Saturday 16 January 2027 for September-2027 entry), with a late-October registration deadline. Oxford High School's application deadline for the same cycle is Sunday 8 November 2026, with outcome letters sent to families in December. So even the independent route wants your child at their best from the first weeks of Year 6.

One important caveat runs through this whole guide: the 11+ is not one uniform exam. Grammar-school papers, individual independent-school tests and the ISEB Common Pre-Test weight the four core skills differently, and Oxford's day schools mostly set their own assessments rather than using the ISEB test. I've written a fuller breakdown in my guide to Oxford independent-school 11+ entrance exams and a companion piece on grammar schools near Oxford. The point for timing is simple: work backwards from your specific target schools' test dates, because those dates set your deadline.

If you want one sentence to take away, it's this: for most children, structured 11+ preparation works best as a core year in Year 5, sitting on top of good habits built earlier. That gives roughly twelve months of steady work before the September tests, or a little more before the independent-school assessments in the winter of Year 6.

I'm not alone in landing on Year 5. One tuition provider, Simply Learning Tuition, recommends "12 to 18 months of gentle preparation for the 11 Plus exam, starting in the Autumn or Spring term of Year 5." I'd stress that this is a single company's rule of thumb rather than an official standard — but it lines up closely with what I see working across Oxford families year after year.

Why Year 5 specifically? Because it's long enough to teach every question type properly, build genuine fluency and still leave room for a normal childhood — but short enough that a nine- or ten-year-old can sustain focus without burning out. Start much earlier with formal papers and you risk stale, resentful children by the time it matters. Start in Year 6 and you're compressing a year's work into a term, usually with more pressure and less margin for the wobbles that are completely normal at this age.

The reassuring part, and I mean this, is that the content isn't the mountain parents fear. ISEB — the body behind the widely used Common Pre-Test — states plainly that "extra revision is not necessary for your child to excel," because the test is mapped to the national curriculum and your child should already be familiar with the topics. Preparation, done well, is mostly about familiarity with formats and timing, and quiet confidence — not learning vast tracts of new material.

If Year 5 is the core year, what comes before it? Not exam prep — please, not exam prep. The years before Year 5 are for the quiet foundations that make the core year easy rather than frantic. Done right, this groundwork is invisible: your child never knows it was "for the 11+" at all.

Four skills sit at the heart of the ISEB Common Pre-Test — English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning — and the same skills underpin most other 11+ formats. The good news is that three of the four are built far more by everyday habits than by workbooks. Here's where I'd put the energy in Year 3 and Year 4:

None of that looks like tutoring, and that's the point. A child who arrives in Year 5 reading widely, comfortable with number, and unbothered by a puzzle has already done the hardest part. If you want a structured hand with these foundations, that's exactly what primary tuition in Oxford is for — building the KS2 base that makes 11+ preparation feel like a small step rather than a leap.

Let me lay the whole thing out as a table. This assumes a September grammar test or a winter independent-school assessment at the start of Year 6 — adjust the end point to your target schools' actual dates. Think of it as a shape to follow, not a schedule to enforce; every child moves at their own pace.

A word on the independent route: because Oxford's day-school assessments fall from late autumn of Year 6 into January, you have a little more runway than the grammar timeline above. Preparation can sensibly continue through the autumn term of Year 6, rather than peaking in the summer holiday. But the groundwork and the Year 5 core year are the same either way.

This is where good intentions go wrong. Faced with a big test, the instinct is to do more — longer sessions, more papers, weekends swallowed whole. It's almost always counterproductive at this age.

The evidence here is unusually clear. The "spacing effect" — spreading learning across short, regular sessions rather than cramming — is one of the most reliably replicated findings in learning science. The Learning Scientists summarise classroom studies, including experiments with ten-year-olds and Year 5 pupils, showing spaced practice produces more durable learning "in a real classroom setting with primary school children," and that massed practice (long cramming sessions) depletes working memory. In plain terms: little and often genuinely beats the weekend marathon, and not by a small margin.

So what does "little and often" mean in hours? Here I have to be honest that the specific figures come from tuition providers rather than any regulator, so treat them as rules of thumb that vary. As a working guide, I aim for roughly 20 to 30 minutes on most days through Year 5 — the equivalent of a few hours a week — rising modestly closer to the test. I'd be wary of pushing much past about ten hours a week even in the final stretch; beyond that, tired children stop improving and start dreading the whole thing.

Remember ISEB's own line: extra revision is not necessary, because the test is mapped to what your child already learns at school. That's your permission to keep it proportionate. The aim is a child who walks in familiar with the formats and calm about the clock — not one who has done every practice paper in print. If maths in particular is a source of tension, my note on helping a child with maths anxiety may be more useful than another workbook, since an anxious child underperforms their real ability.

Age on the birth certificate isn't really the question. Readiness is. A child who's fluent with number, reads for pleasure, can sit with a puzzle without melting down, and is curious rather than crushed by challenge is ready to begin a structured Year 5 — whatever the calendar says.

Equally, there's no shame in holding off. If your child is still finding core KS2 maths or reading a struggle, the honest kindest move is often to shore up those foundations first rather than layering reasoning practice on shaky ground. Strong maths tuition and reading confidence do half the 11+ job before "11+ prep" even begins, and they're worth having whether or not your child ends up sitting the test.

Two things I'd gently warn against. First, the temptation to over-coach. There's a cautionary view — reported in the press and attributed to education experts like the Good Schools Guide — that a child can be coached so hard they scrape into a school they then can't keep pace with. It's an opinion rather than a settled finding, but it's one worth holding in mind: the goal is a good fit, not a place won at any cost. Second, remember that qualifying in a grammar test doesn't guarantee a place, because catchment and oversubscription rules apply — so keep the 11+ as one option among several, and treat a strong plan B as essential, not a fallback.

If you're reading this in Year 6 with the tests looming, don't panic — and don't write it off either. Plenty of children prepare in a compressed window and do well. It simply means being strategic rather than trying to do everything.

Start with the official familiarisation materials so formats are never a surprise. ISEB, for instance, provides a free official Walkthrough of its test-player interface so children know exactly what the screen will look like — a small thing that removes a surprising amount of test-day anxiety. Then triage: identify the two or three weakest question types and focus there, rather than spreading thin across everything. Protect sleep and calm above extra hours; a rested, confident child outscores an exhausted, drilled one almost every time.

This is also where a tutor earns their keep — not by cramming, but by covering every question type methodically, spotting the specific gaps, and giving you an honest read on whether the target schools are realistic this cycle. That's exactly how I structure one-to-one 11+ tuition across Oxford: a diagnostic first, then a focused plan, with candid feedback rather than false reassurance. Whether you start in Year 4 or in a hurried Year 6, the principles are the same — steady, sourced, and calm beats frantic every time.
