11+ Maths Tutor: How to Find One Your Child Can Rely On

The short answer: the fastest way to find an 11+ maths tutor you can rely on is to stop trusting the bio and start checking the evidence — a verified identity and DBS, real familiarity with the 11+ maths format your target schools use, and a track record you can actually see rather than one the tutor has written about themselves. On Tutorwise, that evidence is turned into a single computed credibility score, so you are comparing what a tutor has earned, not how well they market. This guide explains what a good 11+ maths tutor really does, why the usual search leaves parents guessing, and how to pick with confidence.

What an 11+ maths tutor actually teaches

The 11+ is not a harder version of the Year 5 maths lesson. It tests whether a child can apply number, ratio, geometry and problem-solving quickly and accurately, often under time pressure, and usually alongside a maths-heavy numerical reasoning paper. A strong 11+ maths tutor works on three things at once:

• The maths itself — securing the number work, fractions, percentages, ratio, area and the multi-step word problems that carry the marks.
• Reasoning under the format — numerical and quantitative reasoning questions that dress familiar maths up in unfamiliar clothes, so the child has to spot the maths before they can do it.
• Exam technique — pace, when to skip and return, checking, and staying calm when a question looks strange. A capable Year 5 mathematician can still lose marks purely on timing.

Which of those three matters most depends on the schools you are aiming for. A GL Assessment paper, a CEM-style paper and an individual grammar or independent school's own paper reward different things. So the first useful question about any tutor is not "are you good at maths" — it is "do you know the specific 11+ maths format my child is sitting, and can you show me you have prepared children for it before?"

The real problem: anyone can call themselves an "11+ specialist"

Here is the honest difficulty. On an ordinary tutor directory or a local noticeboard, "11+ maths specialist" is a phrase a tutor types about themselves. There is no check behind it. Two tutors can write the identical line, charge the identical rate, and be completely different in practice — one a former prep-school teacher who has walked many children through Sutton and Kent grammar papers, the other a capable graduate who has never seen an 11+ paper.

As a parent you are usually deciding in the dark, on the strength of a friendly message and a confident profile. That matters more for the 11+ than for almost any other tutoring, because the exam happens once, the timing is fixed years in advance, and you often cannot tell whether the preparation worked until the results arrive. A weak choice is not a wasted lesson — it can be a wasted year.

How Tutorwise turns credibility into something you can check

This is the gap Tutorwise is built to close, and it is worth understanding how, because it changes how you choose.

On Tutorwise, a tutor's credibility is not a self-written bio. It is a computed score — the platform calls it Credibility as a Service (CaaS) — built from real, checkable signals rather than claims. The score weighs several things, and it weighs delivered outcomes most heavily: the sessions a tutor has actually taught and how the families they taught rated them. On top of that it factors in credentials and qualifications, verified trust signals such as a checked identity and DBS, the tutor's network and reviews, and how completely and openly they have set up their profile.

Two design choices make this useful to a parent rather than just a number:

1. There is a hard gate. A tutor does not get a public credibility score at all until they have verified their identity or completed onboarding. A blank, unverified profile cannot hide behind confident wording — it simply has nothing to show.
2. Verification adds points; it is not a badge a tutor awards themselves. A passed DBS check and a confirmed identity lift the score because the platform confirmed them, not because the tutor ticked a box.

So when you compare two 11+ maths tutors on Tutorwise, you are not comparing two paragraphs of self-description. You are comparing two scores that were earned from real teaching, real reviews and real verification — and you can see what each one is made of. That is the difference between trusting a listing and trusting an audited record.

A worked example

Picture a parent in the spring of Year 5, aiming at two local grammar schools that use different maths formats. Two tutors reply to the same enquiry.

The first has a warm, well-written profile and says he specialises in the 11+. There is no way to know how many children he has prepared, whether his DBS is current, or how past families found him.

The second has a Tutorwise profile showing a high, computed credibility score. You can see it is built mostly from delivered sessions and reviews from parents whose children sat the same style of paper, a verified identity, a current DBS, and clearly listed experience with both formats you care about. Nothing there is a claim you have to take on faith — each part was checked or earned.

The maths of the decision changes completely. You are no longer picking on charm. You are picking the tutor whose record answers the one question that actually matters: has this person reliably prepared children like mine, for the exam mine is sitting?

What to check before you book

Whether you use Tutorwise or not, the same short checklist protects you:

• Verified identity and a current DBS. Non-negotiable for anyone teaching a child, in person or online. On Tutorwise this is part of the score; elsewhere, ask to see it.
• Format-specific experience. Not "the 11+" in general — the specific maths and reasoning papers your target schools set.
• Evidence you can see, rather than testimonials the tutor chose. Reviews tied to real, completed sessions are worth far more than hand-picked quotes.
• A clear plan. A good tutor will describe how they diagnose gaps first, then build maths and timing together, rather than promising a fixed 11+ course that ignores your child's actual weak spots.
• A trial that tells you something. One session should leave you with a genuine read on how your child responds to the tutor, rather than only a friendly hour.

If you want the longer version of this thinking, our guide on how to choose a tutor you can actually trust walks through the same principles for tutoring generally.

Online or in person for 11+ maths?

Both work well, and the honest answer is that the tutor matters far more than the medium. In-person lessons suit some younger children who focus better sitting beside an adult at the kitchen table, and they remove any question of the technology getting in the way. Online lessons open up a much wider pool of tutors who genuinely know your target papers, which for a format as specific as the 11+ is often the deciding factor — the right specialist may not live within driving distance.

For 11+ maths in particular, a shared online whiteboard handles the diagrams, working and step-by-step method well, and lessons are easy to fit around a busy Year 5 or Year 6 week. Whichever you choose, judge it on the same evidence: the tutor's real experience with your papers and a track record you can check. On Tutorwise you can compare online and in-person tutors side by side on exactly that basis, rather than defaulting to whoever happens to live nearby.

When to start

There is no single right answer, and honest advice depends on your child, not a fixed rule. As a general shape: many families begin structured 11+ maths preparation around a year out — commonly in Year 5 — leaving time to secure the underlying maths first and then layer in reasoning and timed practice, without cramming. Starting later is not hopeless; it simply narrows what you can realistically cover, so the tutor's job shifts towards the highest-value gaps and exam technique. A good tutor will tell you straight where the time can and cannot stretch, rather than selling you a longer programme than your child needs.

The value, honestly

Good 11+ maths tutoring is an investment, and it is fair to weigh it. The point is not to buy the most hours — it is to buy the right preparation from someone whose record you can trust, so the money and, more importantly, your child's year of effort are not wasted on guesswork. That is exactly why a checkable credibility score is worth more to you than a lower rate attached to an unverifiable profile. The cheapest tutor is expensive if the year does not count.

The aim is a calm, prepared child who walks into the exam knowing the maths and the format — confident because they were genuinely ready, not because anyone told them to be.
