11 Plus Tutor: What to Look For, When to Start, and the Mistakes That Cost Children Grammar School Places

Last updated: 3 June 2026

Why the 11 Plus Is Unlike Any Other Exam Your Child Will Sit

Think about every other important exam in the UK education system. GCSEs — nine or ten of them, taken across weeks, with resit opportunities if things go wrong. A Levels — two years of preparation, multiple sittings. Even university applications have clearing as a fallback.

The 11+ has none of that. One exam. One morning. One chance. Grammar school or not.

And here is the uncomfortable truth that most parents discover too late: the 11+ is not actually that hard in terms of content. Verbal reasoning, non-verbal reasoning, maths, English — these are things a Year 5 or Year 6 student is fully capable of handling. The difficulty is the format, the time pressure, and the margin for error. In competitive areas like Essex, Buckinghamshire, and parts of London, the gap between a child who earns a grammar school place and one who misses it is often two or three marks. Two questions. Sometimes one.

Children who have done every practice paper in the book but were never taught to manage their time within sections — to skip hard questions and return — regularly leave marks on the table they were completely capable of claiming. That is a tutoring failure, not a child’s failure.

What a Good 11 Plus Tutor Actually Does

There is a world of difference between a tutor who sits next to a child and works through papers, and a tutor who analyses why that child is losing marks and fixes it. The first is fairly easy to find. The second is what Tailored Tutors provides.

The tutors we place for 11+ preparation are exam professionals — DBS-checked Heads of Department, current and former examiners. They are not first-year university students who happen to know primary maths and English. They have spent years watching where children go wrong in these specific papers, and they know how to fix it.

A genuinely effective 11 plus tutor will:

• Give you an honest starting assessment — not to discourage, but because you cannot fix a problem you have not diagnosed. Which sections are losing the most marks? Which question types? Why?
• Work to the specific exam your target school uses — GL Assessment, the ISEB Common Pre-Test, and CEM formats are meaningfully different, and the preparation strategy for one does not fully transfer to the others
• Teach timed exam strategy explicitly — when to move on, how to manage a difficult question, how to check work in the final 90 seconds without rushing and introducing errors
• Address exam anxiety directly — this is not a soft concern. A child who freezes under pressure or second-guesses themselves in the room will underperform relative to what they actually know, regardless of how well they prepared at home
• Build progressively — confidence in the 11+ is not given; it is earned through structured practice under increasingly realistic exam conditions

“The children who fail the 11+ are rarely the ones who couldn’t do the work. They’re the ones who weren’t taught how the exam works. The format, the timing, the specific tricks of the board — these are learnable. Every single one of them. That’s what our tutors focus on from day one.”

— Rich Thompson, Founder, Tailored Tutors

When to Start: The Timeline Most Parents Get Wrong

The most predictable mistake in 11+ preparation is starting too late. The exam lands in September or October of Year 6. By the time a child begins Year 6, there are fewer than twelve weeks of term until that morning arrives. If you are starting structured preparation in September of Year 6, you are not preparing — you are cramming.

The right time to begin is Year 5, ideally by January. That gives roughly eighteen months of preparation at a manageable pace. Enough time for a child to build genuine fluency with the question formats — not just surface recognition, but the kind of automatic processing that takes the cognitive load out of familiar question types and reserves mental energy for the hard ones.

Year 6 starts are not hopeless. But the preparation needs to be more intensive, more focused, and the child needs to be able to handle that pressure. Some can. Some cannot. An honest conversation with an experienced 11+ tutor will tell you quickly which category yours falls into.

A Realistic 11 Plus Preparation Timeline

• Year 4 / Early Year 5: Core numeracy and literacy. No exam-specific preparation yet — build the foundations so the 11+ work sits on something solid.
• January to July, Year 5: Begin structured 11+ tutoring. Introduce the question formats for your specific board. Build speed and accuracy. Identify weak areas early, while there is time to address them properly.
• September to December, Year 5: Consolidate and accelerate. Timed practice under exam-like conditions begins. Persistent weaknesses get targeted attention.
• January to July, Year 6: Exam-focused preparation in earnest. Past papers under full conditions. Strategy work. Mock exams. Debrief every session against specific mark loss patterns.
• August to September, Year 6: No new content. Cement what is already known. Confidence-building. Routine, familiarity, composure.

What Exam Will Your Child Actually Sit? GL Assessment, ISEB Pre-Test, or a School’s Own Paper

Before you book a single session, before you buy a single practice paper, find out which exam your target schools use. This is not a minor detail. It changes the entire preparation strategy.

For most grammar schools, the answer in 2026 is GL Assessment — the dominant provider since CEM stopped offering paper-based 11+ exams in late 2022. Most grammar school consortia switched to GL Assessment for the 2023‑24 admissions season and have stayed with it. GL papers follow predictable, well-established formats. The question types recur across papers with recognisable patterns. If you know what to expect, you can prepare for it specifically.

CEM (Centre for Evaluation and Monitoring) still exists but has narrowed. The current product, sometimes called Cambridge Select Insight, is online and adaptive — the questions get harder as your child performs better. It’s used by a small number of selective schools. If your target school uses it, the preparation strategy is different from GL, so you need a tutor who has worked with it specifically.

For independent (private) senior schools, the dominant format is the ISEB Common Pre-Test. This is an adaptive, online, computer-based exam covering English, Maths, Verbal Reasoning, and Non-Verbal Reasoning (2 hours 15 minutes total). It’s used by many of the most competitive UK private schools — Eton, Harrow, Winchester, Wellington, St Paul’s, and Westminster among them. Importantly, ISEB results go directly to schools — parents don’t see them.

A few elite schools run their own bespoke entrance exams instead of (or in addition to) the ISEB. Westminster’s 11+ entry is the standout example — a school-specific assessment held at the school in November of Year 6.

The right preparation differs for each format. A tutor with deep GL Assessment experience will not necessarily know how the ISEB adaptive scoring works, or what Westminster’s own paper looks for. At Tailored Tutors, the first thing we establish when matching a family is which exam (or exams) their target schools use, and we place tutors with direct, current experience of that specific format.

Why Online Tutoring Works for the 11 Plus

Tailored Tutors is exclusively online. For some parents that raises an eyebrow, particularly for younger students. It should not.

The practical advantages are real. No travel time. No fatigue from getting to and from sessions. The child works from a space they know, which reduces the background anxiety that some children carry into in-person tutoring. And — most importantly — geography no longer limits who you can hire. You are not confined to whoever lives within five miles. You are choosing from a national pool of 11+ specialists.

The technology is not a barrier. Shared whiteboards, real-time annotation, document sharing — verbal and non-verbal reasoning questions, including the visual pattern work in non-verbal sections, are handled in live online sessions with the same effectiveness as on paper. Our tutors use resources specifically designed for online 11+ delivery.

The Vetting Process: Why It Matters for a One-Shot Exam

The UK tutoring market is completely unregulated. There is no qualification required, no minimum experience threshold, no oversight body. A first-year university student can charge £25–£35 an hour and call themselves a tutor — and many do.

For most exam preparation, a cheap, inexperienced tutor is an expensive waste of time. For the 11+, it can cost a grammar school place. The stakes are different.

Tailored Tutors operates a strict top 20% acceptance policy. Founder Rich Thompson personally interviews and assesses every tutor before they go on the roster. Those who are accepted are DBS-checked career professionals: former Heads of Department, current and former examiners, educators with verifiable track records. For 11+ specifically, we place tutors with demonstrated experience on the relevant exam board’s format — not tutors who are broadly good at primary maths and English.

Five Questions to Ask Any 11 Plus Tutor Before You Commit

Whether you are considering Tailored Tutors or looking elsewhere, ask these questions before booking sessions. The answers will tell you quickly whether you are speaking to a specialist or a generalist:

1. “Which exam does our target school use — GL Assessment, ISEB Common Pre-Test, or a school-specific paper — and how much direct experience do you have with that specific format?” A tutor who is vague on this is not a specialist.
2. “How do you diagnose where a child is losing marks?” The answer should be specific — which sections, which question types, which patterns. “We’ll do lots of papers” is not an answer.
3. “How do you teach timed exam strategy?” Listen for concrete techniques: section timing, skip-and-return, the approach to a question they are not sure about. Vague reassurance is a red flag.
4. “How do you work with a child who gets anxious under exam conditions?” Exam anxiety is a performance variable. A tutor who has no structured approach to it will leave marks on the table.
5. “Can you tell me about children you have helped get into grammar school?” Specifics — schools, timescales, starting points — are more useful than general praise.

The Mistakes That Cost Children Grammar School Places

Across our team’s combined years of 11+ tutoring and examining experience, the same patterns recur in how children lose marks. None of these are inevitable. All of them are correctable:

• Running out of time in the verbal reasoning section. The single most common source of mark loss in GL Assessment papers. Children who have not practised strict section timing — with a clear plan for what to do if they fall behind — regularly spend too long on hard questions and run out of time before the easy ones at the end.
• Misreading non-verbal reasoning instructions. The visual nature of these questions makes them easy to misinterpret. A simple technique for reading the instruction carefully and eliminating obvious wrong answers before committing takes minutes to teach and recovers marks consistently.
• Not leaving time for a final check. In the maths sections, the majority of mark loss comes from calculation errors — not from not knowing the maths. A 90-second check pass at the end of a section typically recovers two or three marks that would otherwise be lost to arithmetic slips.
• Doing papers without debriefing them. A child who has completed forty practice papers but has never been shown which question types they consistently get wrong is accumulating practice, not learning. Volume without analysis is one of the most common preparation traps.
• Underperforming on exam day despite strong preparation. Some children who have prepared thoroughly and accurately predict their own performance still underperform on the day. Mock exams under realistic conditions — including time pressure, formal setting, and the emotional weight of a real exam — are the only reliable way to address this before it matters.

Frequently Asked Questions

How many sessions will my child need?

There is no universal answer — it depends on the starting point, the target schools, and the time available. A child beginning in Year 5 typically does one session per week of 50–60 minutes, increasing to two sessions per week in the final six months. A child starting in Year 6 will need a more intensive approach. At Tailored Tutors, the initial consultation is specifically designed to give you an honest, specific picture of what your child needs — not a generic package.

Is online tutoring as effective as face-to-face for the 11+?

Yes — and for many families, more so. The quality of the tutor is what determines outcomes, not whether sessions happen in person or online. Online removes the logistics, opens up access to specialist tutors nationally, and puts the child in a comfortable, low-pressure environment. Tailored Tutors operates exclusively online, and our tutors have years of online teaching and tutoring experience between them.

Which exam will my child sit — GL Assessment, CEM, or ISEB?

It depends on the school. Most grammar schools now use GL Assessment, following CEM’s discontinuation of paper-based 11+ exams in late 2022. A small number of selective schools use CEM’s newer online format (Cambridge Select Insight), and many independent (private) senior schools use the ISEB Common Pre-Test. Some elite schools run their own bespoke exams instead. The right preparation strategy is different for each. Establishing which format your target schools use is the first step in any structured 11+ preparation, and it’s the first thing we’ll confirm in your initial consultation.

How old are children when they sit the 11+?

Most children are 10 or 11 when they take the exam, in September or October of Year 6. Registration deadlines and application processes for grammar schools typically fall much earlier — often a year or more before the exam itself. Check your target schools’ specific timelines well in advance.

How much does an 11 plus tutor cost?

At Tailored Tutors, expert 1-to-1 sessions start from £60–£90 per hour. That reflects tutors with verified credentials, exam board specialism, and a demonstrable track record — not generalist students charging a third of the rate but without the relevant experience. On a one-shot exam, the cost of the wrong tutor is a grammar school place. That calculus is worth thinking through carefully.

Is there a free trial before I commit?

Yes. Every placement begins with a free 30-minute consultation call — with an experienced educator, not a sales representative — to understand your child’s current position and what preparation is needed. After that, there is a free rapport session with the matched tutor before any payment is required. No lock-in contract. Sessions are booked week to week, with 24-hour cancellation notice for individual sessions.

My child is already in Year 6 — is it too late?

No. But every week now matters. The preparation needs to be more intensive and focused to compensate for the shorter runway. Get started immediately, and make the first session a thorough diagnostic so that every subsequent session is targeted at the highest-leverage weaknesses. Contact Tailored Tutors — the initial consultation will give you an honest assessment of what is achievable in the time available.
