Driving Instructor Pass Rates in the UK 2026: What ADI Grades and Data Really Tell You Before You Book

Every learner asks the same question before booking lessons: is this instructor any good? The honest answer is that the UK does not publish a per-instructor pass rate you can look up. What it does publish is a set of related figures — ADI qualifying pass rates, Standards Check grades and centre-level test data — and if you know how to read them, they tell you a surprising amount.

Here is what the 2026 data actually shows, what it does not show, and how to use it when choosing who teaches you to drive.

There Is No Official Instructor Pass Rate League Table

This is the first thing to understand. The DVSA does not publish the percentage of pupils each approved driving instructor gets through the test. Any website claiming to rank individual instructors by pass rate is using self-reported figures or estimates, not official data.

What the DVSA does publish is the grade an instructor received at their most recent Standards Check — and instructors can choose whether to display that publicly on the official Find a Driving Instructor service.

ADI Grades: What A, B and Fail Actually Mean

Every approved driving instructor is periodically observed teaching a real lesson by a DVSA examiner. They are scored across 17 competencies and given a grade:

Grade	Score	What it means
Grade A	43–51	A high standard of instruction
Grade B	31–42	A sufficient level of competence — meets the national standard
Fail	0–30	Below standard; the instructor must be reassessed and risks removal from the register

Two things worth knowing. First, a Grade B is a pass — it is not a warning sign. The large majority of working instructors are Grade B. Second, an instructor who has not published a grade has not necessarily done badly; disclosure is voluntary and plenty of excellent instructors simply have not opted in.

The Qualifying Tests: Why Instructors Are Harder to Become Than You Think

Becoming an ADI means passing three tests, and the third is brutal.

• Part 1 — theory and hazard perception, at a much higher standard than the learner theory test
• Part 2 — an advanced driving ability test, with a far tighter fault allowance than the learner practical
• Part 3 — the instructional ability test, assessed on the same 17 competencies as the Standards Check

DVSA figures for the 2025–26 reporting year put the Part 3 national pass rate at roughly 28–30%, making it the hardest of the three by a wide margin. Roughly seven in ten candidates fail at the first attempt. That statistic is useful context: the person teaching you has cleared a genuinely demanding bar.

What the Data Says About Instructor Numbers in 2026

The wider picture matters too. The ADI register has been under pressure, with industry analysis pointing to a substantial net loss of instructors over the past five years while learner demand has risen. Fewer instructors, combined with driving test waiting times still averaging around 20 weeks nationally, means good instructors get booked up months ahead.

The practical consequence for you: the instructor with immediate availability may simply be the one nobody has recommended. Being willing to wait a few weeks for a well-regarded instructor is often the better decision.

Centre Pass Rates Are Not Instructor Pass Rates

It is tempting to judge an instructor by the pass rate of the test centre they use. Resist it. Centre pass rates reflect the local road network far more than the local teaching quality — which is why remote rural centres sit above 60% while dense city centres sit in the thirties.

An instructor working in central London with a 40% pupil pass rate may well be a better teacher than one working in a quiet market town with a 65% rate. Read centre data as information about the roads, not about the people.

How to Actually Judge an Instructor

1. Check they are on the DVSA register. An approved instructor displays a green octagonal badge in the windscreen. A pink triangular badge means a trainee (PDI) — legal, but still qualifying.
2. Use the official Find a Driving Instructor service to confirm registration, see any disclosed grade, and check whether they have signed the ADI Code of Practice and committed to continuing professional development.
3. Ask directly about their grade and pass rate. A confident instructor will tell you. Be wary of anyone who reacts defensively.
4. Ask how they structure lessons. Good instructors work to a plan, review progress and tell you honestly when you are not test-ready.
5. Ask about test-readiness policy. An instructor who will let you take a test you are not ready for is costing you money.
6. Take one lesson before committing to a block. Rapport matters enormously, and a discounted ten-hour block with the wrong instructor is a false economy.
7. Check what the lesson price includes — door-to-door pick-up, use of the car for the test, and whether time is deducted for driving to the practice area.

What Really Moves Your Odds

The uncomfortable truth in the data is that instructor quality is only one variable. The national car practical pass rate has hovered around 50%, and the biggest differences between candidates who pass and those who do not are hours of varied practice, familiarity with the local test routes, and honest self-assessment about readiness.

A good instructor accelerates all three. But the private practice you do between lessons — on the actual roads your examiner uses — is what turns competent driving into a pass.
