11 Plus Tutor: How to Choose One That Actually Prepares Your Child

Choose an 11-plus tutor on evidence of how they deliver and whether they are verified to work with children — not on how good their profile looks. The 11-plus is high-stakes and time-boxed: your child sits it once, usually in Year 6, and the preparation window is roughly a year. A tutor who reads well but teaches poorly costs you that window and the fee, and you rarely find out until it is too late to change course. So the sensible way to choose is to ground the decision in two things a marketing profile cannot fake: a track record of real delivery, and verified safeguarding.

Why the 11-plus makes tutor choice unforgiving

Most tutoring decisions are reversible. If a weekly maths tutor is a poor fit, you notice over a term and swap them out with little lost. The 11-plus removes that safety net. The exam is sat on a fixed date, competition for places is real — England has around 163 state grammar schools, according to the Grammar School Heads Association, and popular ones are heavily oversubscribed — and there is no retake in the same admissions round. Every week of preparation with the wrong tutor is a week you cannot get back.

That changes what "good" means. For a long-running subject tutor, likeability and availability carry a lot of weight. For the 11-plus, the tutor's ability to prepare a child for a specific format, on a specific timeline, is the whole job. The cost of a mismatch is not just the hourly fee — it is the opportunity cost of the one preparation window your family gets.

What a polished profile hides

A tutor's own profile is a marketing document. It tells you what they want you to know: qualifications listed, a warm photo, a paragraph of confident copy, perhaps a five-star average from a handful of reviews. None of that is dishonest, but none of it answers the questions that actually predict a good outcome. Does this person reliably show up and deliver? Have they prepared children for the exam board your target school uses? Are they verified to work with children, or are they simply asserting that they are?

Presentation and delivery are only loosely correlated. The best-written profile in a marketplace is often not the best teacher; it is the best copywriter. Choosing on presentation is how families end up three months into preparation with a tutor who is pleasant, punctual and quietly ineffective.

Ground the choice in delivery, not presentation

This is the problem Tutorwise's Credibility as a Service (CaaS) score is built to solve. Instead of asking a tutor to describe how good they are, CaaS scores a profile on evidence the platform can see — completed sessions, verified credentials, real connections, and confirmed safeguarding checks. It is a credibility signal you can read at a glance, and it is far harder to game than a self-written bio.

The score is event-driven: it updates in under a second as a tutor completes sessions, adds a verified credential, or passes a check. A tutor cannot inflate it by rewriting their profile. They raise it by delivering, over time, the things that actually matter to a parent.

For an 11-plus decision, that is the right foundation. You are not trying to find the tutor who sounds most reassuring on a Sunday evening. You are trying to find the one with a demonstrated record of preparing children well.

The six things a credibility score actually measures

CaaS is built on a six-part model, drawn from real platform data and weighted towards the parts that predict a good outcome:

• Delivery and Quality (40%) — the largest share, and rightly so. This is the tutor's actual record of completed, well-rated sessions. It is the closest signal to "will they teach my child well".
• Credentials and Expertise (20%) — verified qualifications and subject experience recorded as platform data, not just claimed ones.
• Network and Connections (15%) — the strength of a tutor's real, confirmed relationships, tracked as connection data on the platform.
• Trust and Verification (10%) — identity, DBS and onboarding checks, scored from verification data as a tutor earns them.
• Digital Integration (10%) — how completely and actively the tutor maintains their presence and tools, measured from usage data.
• Community Impact (5%) — contribution beyond their own bookings, drawn from engagement data.

Notice that delivery is worth four times as much as raw credentials. A stack of certificates does not lift a tutor far if there is no record of teaching well behind it. That weighting is deliberate: it rewards the tutors who do the job, not the ones who merely describe it.

There is also a hard floor. A tutor gets no CaaS score at all until they are either identity-verified or have completed onboarding. An unverified profile does not score low — it does not score. That single rule filters out the profiles you should not be considering in the first place.

Verified safeguarding is a floor, not a feature

For any adult working with children, an enhanced DBS check is the baseline, not a bonus. The distinction that matters is between a tutor who says they hold a DBS check and one whose check has been verified by the platform. On Tutorwise, verification lives inside the Trust bucket, so a confirmed DBS check is part of the credibility score itself rather than an unchecked claim in a bio.

Ask directly, before you book: is this tutor's DBS check verified, and when was it issued? A tutor who prepares children for a life-shaping exam should meet the safeguarding bar without hesitation. If verifying it is awkward, that is your answer. Our guide to what a DBS check actually tells you about a tutor walks through exactly what to confirm.

A practical checklist for choosing an 11-plus tutor

Use the profile as a starting point, then test it against evidence:

1. Check the credibility score first, not the bio. A strong delivery record tells you more than any paragraph the tutor wrote about themselves.
2. Confirm verified safeguarding. Verified DBS and identity — not a claim. This is non-negotiable for the 11-plus.
3. Match the tutor to the exam. The 11-plus is not one exam. Grammar schools use tests from GL Assessment, CEM, or the ISEB Common Pre-Test, and the format varies by region and school. Ask which boards the tutor has prepared children for, and whether it matches your target schools.
4. Ask about method, not just results. How do they build exam technique and timing under pressure? A good 11-plus tutor teaches the format and the pacing, not only the content.
5. Agree how you will see progress. Regular, honest feedback on where your child stands beats a reassuring monthly "all going well".
6. Start early enough to change course. Begin the search with enough runway that if the first tutor is not right, you can switch without losing the window.

Match the tutor to the exam board

This is the step families most often skip. A tutor who is excellent at GL Assessment-style papers may be a weaker fit for a school using the ISEB Common Pre-Test, which is adaptive and sat on screen. The content overlaps, but the technique, timing and question style differ. Find out which test your target schools use — most publish this on their admissions pages — and choose a tutor with a genuine track record on that format. A credibility score built on real delivery makes that easier to judge, because it reflects work done rather than breadth claimed.

The same discipline applies across the wider tutoring decision. If you are weighing tutors for GCSE or A-level alongside the 11-plus, our guides on choosing a tutor you can trust and finding a GCSE or A-level maths tutor apply the same evidence-first approach.

Frequently asked questions

How early should we start 11-plus tutoring? Most families begin in Year 5, giving roughly a year of steady preparation before the exam in Year 6. Starting earlier can help build core skills without pressure; starting much later compresses the window and leaves little room to change tutors if the first is not the right fit.

Is a high hourly rate a sign of a better 11-plus tutor? No. Rate reflects what a tutor chooses to charge, not their record of delivery. A verified track record of preparing children well is a far better signal than price. Judge on evidence of results and safeguarding, then consider whether the rate fits your budget.

What is a CaaS score and why should I look at it? Credibility as a Service (CaaS) is a Tutorwise score that rates a tutor on evidence the platform can verify — completed sessions, confirmed credentials, real connections and safeguarding checks — rather than on self-description. It is weighted towards actual teaching delivery, so it is harder to inflate than a written profile.

Does every tutor have a verified DBS check? Not automatically — which is why you should confirm it. On Tutorwise, a verified DBS check contributes to the tutor's Trust and Verification score, and a profile does not receive a credibility score at all until the tutor is identity-verified or has completed onboarding. Always ask to confirm the check before booking.

All the grammar schools near us use different tests. Does that matter for choosing a tutor? Yes. Grammar schools use different exam boards — GL Assessment, CEM or the ISEB Common Pre-Test — and the formats differ. Check which test your target schools use, then choose a tutor with a real track record preparing children for that specific board.
