How do I know a driving instructor is qualified? Look for the green octagonal ADI badge displayed in the windscreen during your lesson. It shows the instructor has passed the DVSA's qualifying exams, is registered, and holds an enhanced background check. You are entitled to ask to see it.
Check they are DVSA-approved
To become an ADI, an instructor must pass a series of DVSA qualifying exams, hold an enhanced DBS (criminal records) check, and stay registered with the DVSA, who grade instructors on the standard of their teaching. That registration is what the windscreen badge represents, and it's the baseline you should expect from anyone charging for lessons. If there's no badge on display, ask about it before you book.
Green badge or pink badge?
A green octagonal badge means a fully qualified Approved Driving Instructor. A pink triangular badge means a trainee - sometimes called a PDI, or potential driving instructor - who is still working towards full qualification under a licence to give lessons. A trainee can be a perfectly good teacher, but you're entitled to know which you're learning with, so it's fair to ask before your first lesson.
What else to look for
Once qualification is confirmed, the things that make a real difference day to day are: an enhanced DBS check for safeguarding, especially for younger learners; a dual-control car so the instructor can help if needed; a patient teaching style that matches your confidence level; clear pricing with no hidden deposit; and local knowledge of the roads around your test centre. Genuine reviews from past learners tell you more than any advert, and it helps if the school offers what you actually need - automatic or manual lessons, and options such as a female instructor or lessons in another language.
Questions worth asking
Before you commit, a few direct questions save time later: are you a fully qualified ADI; is the car dual-control; do you teach around my local test centre; and what are your rates, and is there a deposit? Straight answers to these tell you a lot about how an instructor works. MMS is happy to answer all of them before you book - just get in touch.
