11+ Maths Online Tutor: How to Choose One You Can Trust

An 11+ maths online tutor prepares a child in Year 5 or the first weeks of Year 6 for the maths section of a selective-school entrance exam — a state grammar school or an independent senior school — over video rather than at your kitchen table. Done well, online 11+ maths tuition is not a weaker version of in-person prep: a good tutor works through timed papers on a shared whiteboard, watches how your child paces themselves under the clock, and can be a genuine 11+ specialist rather than just the nearest available name. The hard part is not finding someone who says they prepare children for the 11+. It is knowing whether the track record you are being sold is real. On Tutorwise, a tutor's credibility is a computed, checkable score built from verified signals — not a paragraph the tutor wrote about themselves — and when the whole relationship happens over a screen, that difference matters more, not less.

Most families reach online 11+ maths for a practical reason. The well-known local tutors booked up eighteen months ago, or the ones with a real grammar-school record are an hour's drive away, or you live outside a selective area entirely and want a tutor who actually knows your target school's exam. The 11+ is also a market thick with reputation and rumour — the "secret" tutor a neighbour swears by, the recommendation passed around a parents' group with no way to check what sits behind it. Online removes the postcode limit and opens up specialists you could never reach in person. What it also removes is the one free reassurance in-person tuition gives you: meeting the tutor on your own doorstep. That reassurance has to come from somewhere else, and this article is about where.

What the 11+ maths exam actually tests

The 11+ is sat in Year 5 or the opening weeks of Year 6, for entry to a selective secondary. Its maths draws on the Key Stage 2 national curriculum your child already meets at school, but it tests that content faster, deeper and less predictably. School maths usually asks a child to carry out a method they have just been shown; 11+ maths asks them to choose the method, often inside a multi-step word problem where the first step is not obvious. Number, fractions, decimals and percentages, ratio and proportion, early algebra, geometry, measures and data all appear — much the same topics as the SATs, but with the routine stripped out and the pace turned up.

Two features of the exam shape how a child should prepare, and a good tutor builds the whole plan around them. The first is speed under timed conditions: the 11+ rewards a child who can work quickly and accurately in their head, so mental arithmetic fluency — not just knowing how, but knowing fast — is the single biggest difference between a child who finishes calmly and one who runs out of time. The second is age-standardised scoring. Providers such as GL Assessment convert a raw mark into a score adjusted for a child's exact age in months, so a summer-born child is not measured unfairly against an older classmate. It also means the pass mark is a moving target, set by how many places a school has and how many children apply — not a fixed threshold you can simply drill toward.

It helps to know which exam your area uses, because the format is not uniform. Historically two names dominated — GL Assessment and CEM — and in recent years many areas that used CEM have moved to GL Assessment. A large number of independent schools instead use the ISEB Common Pre-Test, which is sat on a computer and adapts its questions to the child as they go. That last point matters for online prep specifically: if your target school's test is itself computer-based, practising maths on a screen with a tutor is rehearsing the real medium, not working around it. A tutor who knows your local consortium's format — a separate multiple-choice answer sheet versus writing in the booklet, and the topics that board tends to lean on — is worth far more than a generalist, and online is how you reach one.

How online 11+ maths tuition actually works

A good online 11+ lesson is built around a shared interactive whiteboard where tutor and child write, sketch and work at the same time. For 11+ maths this is essential, because method matters as much as the answer: the tutor needs to see the working — the order a child tackles a problem, the point where they hesitate, the step they skip — and a shared whiteboard makes that visible in a way that is often clearer online than across a table. The tutor can screen-share a past paper, set a section under the clock, and watch pacing as it happens, which is exactly the skill the exam rewards.

The best online 11+ tutors run timed practice under something close to exam conditions, then do the more valuable half of the work: going back over the paper to find why a mark was dropped — a misread question, a slow method, a careless slip under time pressure — and fixing the pattern rather than just marking the page. What makes tuition work at this level is not more maths in general but the right maths: a tutor spotting the specific thing a specific child gets wrong under pressure — the long-division method that eats time, the ratio question they always misread, the panic that costs three marks in the last five minutes — and drilling that until it holds. That kind of targeted, one-to-one correction is precisely what a full classroom cannot give and what good 11+ prep is built to do.

Sessions tend to be longer and more structured than for a younger child, because an 11+ candidate can sustain focus and the work is genuinely exam-directed. A parent's job is to be within earshot for any technical hitch, not on the call. An 11+ child needs to learn to push through a hard problem without a grown-up stepping in, because that is exactly what the exam room will demand of them.

Why "verified" means something specific on Tutorwise

Here is the problem with an ordinary 11+ tutor listing, a directory, or a word-of-mouth recommendation: almost everything you are told is unchecked. The "fifteen years of grammar-school success", the impressive pass rate, the warm self-description — you are being asked to trust a claim, usually one the tutor wrote themselves. For the 11+, where the market runs on reputation and a child's preparation window is a single short season, that is a thin basis for a decision. Online makes it thinner still, because you cannot fall back on meeting the person face to face.

Tutorwise is built to remove that leap of faith. A tutor's credibility on the platform is not a paragraph they wrote; it is a computed score, built from real signals the platform checks and the tutor cannot fabricate. An enhanced DBS check and a verified identity sit at the centre of it — for anyone working with children, that is the floor, not a bonus. On top of that, the score reflects verified qualifications, the outcomes a tutor has actually delivered through the platform, and reviews from families who booked real lessons. Each of those is a signal Tutorwise has confirmed, weighted into a single number you can read at a glance. A tutor cannot type their way to a high score; they earn it by being who they say they are and by doing the work well.

The practical effect for an 11+ booking is direct. Instead of trusting the neighbour's "secret" tutor or the most persuasive profile, you are reading an earned, checkable score — and because it is computed the same way for every tutor, you can compare two candidates honestly rather than guessing who writes the better bio. When the whole relationship happens over video and the stakes are a school place, that verified floor — a real DBS, a real identity, a real delivered record — is the reassurance that meeting a tutor in person would once have given you at the door.

What to check before you book

A few things separate a strong online 11+ maths tutor from a merely available one. Check the verification badges first — identity and DBS should be confirmed on the platform, not asserted in the write-up. Ask whether the tutor knows your specific exam: the GL Assessment, CEM-legacy or ISEB format your target schools use, and the topics that board leans on. Look for genuine 11+ experience rather than a general "maths tutor", because preparing a ten-year-old to solve non-routine problems at speed is a different craft from teaching the school syllabus. And ask, on a short first session, how the tutor handles timed practice online — the good ones will describe running papers under the clock on a shared screen and reviewing the pattern of dropped marks, not just handing over worksheets.

There is a quiet cost to getting this wrong, and it is worth naming plainly rather than dressing it up. A term with a tutor whose record you could not actually check is not only money spent; it is part of a short, one-shot preparation window given to the wrong person — and 11+ prep does not get a second run. Starting from a verified score rather than a good story is the cheapest insurance you can buy against that, and it is the thing an online booking needs most.

Picture the outcome you actually want: your child walking into the exam able to work quickly and calmly, because the months before it were spent with a tutor who turned out to be exactly who they claimed to be. That is what a computed credibility score is for.

Frequently asked questions

Is online tuition as good as in-person for the 11+? For focused, exam-directed work — timed papers, mental arithmetic, fixing the recurring mistake — online works very well, and it is often better, because it gives you access to a genuine 11+ specialist rather than the nearest available tutor. The shared whiteboard lets the tutor see a child's working and pacing clearly. In-person can have a slight edge for a very young or easily distracted child, but a strong online tutor closes most of that gap. The bigger variable is the tutor, not the medium.

When should my child start 11+ maths tuition? Most families begin in Year 5, which gives a comfortable run of a year or so to build fluency before the exam early in Year 6. Starting earlier is rarely about drilling papers and more about making sure the Key Stage 2 foundations are solid. Leaving it very late is possible but harder, because 11+ maths depends on speed, and speed takes time to build. If you are starting late, a tutor's first job is to be honest about what is realistic.

How do I know an online 11+ tutor's success rate is real? This is exactly what Tutorwise's verification is for. Rather than trusting a self-reported pass rate, you can read a computed credibility score built from checked signals — an enhanced DBS check, a verified identity, confirmed qualifications, delivered outcomes and genuine reviews from families who booked real lessons. Because it is calculated the same way for every tutor, it lets you compare two candidates honestly instead of taking a claim on trust.

What equipment does my child need for online 11+ maths lessons? Very little. A laptop or tablet with a webcam and a reliable internet connection is enough. A stylus or a touchscreen helps a child write working on the shared whiteboard, but a mouse works too. If your target school uses a computer-based test such as the ISEB Common Pre-Test, practising on screen has the added benefit of matching the real exam format. The tutor supplies the whiteboard, papers and materials.

How is the 11+ maths exam different from what my child does at school? It covers similar Key Stage 2 topics but tests them faster and less predictably. School maths often asks a child to apply a method they have just been taught; the 11+ asks them to choose the right method inside a multi-step problem, at speed, under timed conditions. Mental arithmetic fluency and problem-solving under the clock are the parts that most separate 11+ maths from ordinary schoolwork, and they are where good tuition spends the most time.
