How to Choose a Driving Instructor in 2026: ADI Grades, Pass Rates and Red Flags

Your instructor has more influence over whether you pass than your test centre, your car or your nerves. Yet most learners choose one on price alone, or because a friend used them. In 2026, with test slots scarce and lesson costs rising, picking badly is expensive twice over — you pay for the extra lessons and you wait months for another test.

Here is what the badges and grades actually mean, and the questions worth asking before you book.

ADI vs PDI: Green Badge or Pink Badge

Every legal paid driving instructor in Great Britain displays a badge in the windscreen. There are two colours and the difference matters.

• Green badge — Approved Driving Instructor (ADI). Fully qualified. They have passed three demanding exams: a theory and hazard perception test, a driving ability test, and an instructional ability test. They are on the DVSA’s ADI register and are subject to regular standards checks.
• Pink badge — Potential Driving Instructor (PDI). A trainee. They hold a trainee licence allowing them to charge for lessons while they finish qualifying. Some are excellent and enthusiastic; some are still learning to teach.

A pink badge is not automatically a problem, and trainees often charge less. But you should know which you are getting, and you are entitled to ask to see the badge. An instructor charging for lessons with no badge at all is operating illegally — walk away.

Standards Check Grades: A, B or Fail

Qualified ADIs are assessed periodically by a DVSA examiner who observes a real lesson. The result is a grade:

• Grade A — a high standard of instruction. Roughly the top tier of instructors.
• Grade B — a sufficient standard. Perfectly competent; the majority of instructors sit here.
• Fail — the instructor must be reassessed and risks removal from the register.

Instructors are not obliged to publish their grade, but a good one will tell you if you ask. If someone becomes evasive when asked a straightforward professional question, that itself is information.

Questions to Ask Before You Book

1. Are you a fully qualified ADI, and can I see your badge? A straight answer takes two seconds.
2. What is your standards check grade? Grade A or B are both fine. Hesitation is not.
3. What do you charge, and do you offer block booking discounts? Get the per-hour figure and any package terms in writing.
4. What is your cancellation policy? Twenty-four or forty-eight hours is normal. Anything harsher is worth questioning.
5. Will you take me to my test in your car? Confirm this, and confirm the cost of the test-day hire.
6. Which test centre do you normally use, and do you know its routes? Local route knowledge is one of the biggest practical advantages an instructor can offer.
7. Do you teach manual, automatic, or both? Automatic demand has risen sharply; make sure they suit your choice.
8. How do you structure lessons? You want a clear plan, not “we’ll see how you get on”.
9. Will I always have the same instructor? Large schools sometimes rotate. Continuity matters.
10. What happens if the car breaks down on my test day? Agree who covers the rebooking fee before you need the answer.

Red Flags

• No badge in the windscreen. Non-negotiable.
• Large upfront payments. Paying for forty hours before your first lesson leaves you exposed if the relationship does not work. A block of ten is reasonable.
• Regularly cutting lessons short or arriving late while charging the full hour.
• Shouting, sarcasm or belittling. Learning to drive is stressful enough. A good instructor stays calm.
• Pushing you to book a test before you are ready — or, equally, endlessly delaying it to keep selling lessons.
• Refusing to explain a fault. “Just do it my way” is not teaching.
• No written terms. You should know the price, the cancellation policy and the test-day arrangement in advance.

Signs You Have Found a Good One

A good instructor tells you at the end of every lesson what went well, what needs work, and what the plan is for next time. They give you things to practise privately if you have access to a car. They are honest about whether you are test-ready rather than telling you what you want to hear. And they know the local test routes well enough to explain why a particular junction catches people out.

When to Change Instructor

Changing is not disloyal, and it is not a failure. If after several lessons you dread getting in the car, if you are not progressing, or if you feel talked down to, find someone else. Ask for your progress record, settle any outstanding balance, and move on. Most learners who switch wish they had done it sooner.

How the Exam Routes App Can Help

A good instructor plus real route practice is a strong combination. Use your lessons for technique and the app for building familiarity with the roads around your test centre.

• Real test routes recorded around the centre, not guesswork.
• Turn-by-turn navigation so a supervising driver can focus on your driving.
• Offline access for rural stretches where signal drops out.
• Route notes flagging the junctions and roundabouts that catch learners out.
