Becoming an ADI

How to become a driving instructor

Updated 10 July 2026 12 min read

A qualification road passes training materials and trainee and qualified badge shapes.

To become a driving instructor in the UK you must qualify as an approved driving instructor (ADI): be at least 21, have held a full car licence for three of the last four years, pass an enhanced DBS check, then pass the DVSA’s three qualifying tests (Part 1 theory, Part 2 driving ability, Part 3 instructional ability) and register. Test fees are fixed at £81, £111 and £111, plus £300 to register.

That is the route in full. This guide walks through every stage in order, tells you what each part costs and how long it takes, and sets out a realistic timeline and total budget so you can decide whether the ADI route is right for you before you spend a penny.

What is an approved driving instructor (ADI)?

An approved driving instructor is someone the DVSA has qualified and registered to charge learners for driving lessons. Only ADIs (and trainees on a temporary licence) may legally teach car driving for payment on UK roads.

Once you qualify you go on the ADI register, receive a green certificate (the green badge), and must display it in the windscreen when teaching. You become self-employed, set your own hours and rates, and either work independently or join a franchise. There are around 40,000 registered instructors in the UK, and demand for lessons has stayed consistently high, which is part of what makes the career appealing.

What are the requirements to become a driving instructor?

Before you start the qualifying process you must meet the DVSA’s entry requirements. These are non-negotiable and worth checking first, because there is no point paying for training if you do not qualify.

  • You must be at least 21 years old.
  • You must have held a full UK or EU car (category B) driving licence for at least three of the past four years.
  • You must be able to read a number plate from 26.5 metres.
  • You must be a “fit and proper person” to have your name on the register, which means an enhanced criminal record (DBS) check. Motoring convictions, penalty points and any criminal record are all considered.
  • You must not have been banned from driving in the last four years.

The fit-and-proper requirement is assessed by the DVSA on a case-by-case basis. Having points or a past conviction does not automatically bar you, but you should be upfront about your record before investing in training.

What is the ADI qualifying process?

Qualifying as an ADI means passing three separate tests in order. You must pass each one before you can attempt the next, and there is a strict two-year window: once you pass Part 1, you have two years to pass Part 2 and Part 3, or you lose your progress and start again.

StageWhat it testsFeeAttempts
ADI Part 1Theory and hazard perception£81Unlimited
ADI Part 2Your own driving ability£1113 within the two-year window
ADI Part 3Your ability to teach£1113 within the two-year window
RegistrationJoining the ADI register£300Once you have passed all three

The two-year clock and the three-attempt limits on Part 2 and Part 3 are the main reasons people fail to qualify, so it pays to be genuinely ready before you book each test rather than rushing.

What is the ADI Part 1 test?

ADI Part 1 is the theory test, and it costs £81. It is a tougher version of the learner theory test, split into two parts that you sit in one sitting: a multiple-choice section and a hazard perception section, and you must pass both on the same day.

The multiple-choice section has 100 questions across four bands (road procedure; traffic signs and signals; car control and pedestrians; driving test, disabilities and the law; and publications and instructional techniques). You need to score well in every band, not just overall, so you cannot coast on your strong areas. The hazard perception section uses video clips scored on how early you spot developing hazards. Part 1 has unlimited attempts, but you should still prepare thoroughly, because passing well builds the knowledge you will lean on in Part 3.

What is the ADI Part 2 test?

ADI Part 2 assesses your own driving to a much higher standard than the learner test, and it costs £111. The examiner expects an expert, fault-free drive: safe, smooth, confident and to a professional standard.

The test lasts around an hour and includes an eyesight check, “show me, tell me” vehicle safety questions, general driving on a variety of roads, specific manoeuvres, and a section of independent driving. You are allowed a small number of minor faults but no serious or dangerous ones. Many trainees underestimate Part 2, assuming years of driving experience will carry them, but ingrained habits (poor mirror use, rolling stops, imprecise positioning) trip people up. You get three attempts within the two-year window. Professional training before Part 2 is a sensible investment even for confident drivers.

What is the ADI Part 3 test?

ADI Part 3 is the instructional ability test, the hardest and most important part, and it costs £111. It assesses whether you can actually teach: an examiner observes you delivering a real lesson and grades you against a structured competency framework.

You are marked on 17 competencies grouped under three headings (lesson planning, risk management, and teaching and learning strategies), each scored from 0 to 3, for a total out of 51. You need at least 31 to pass (Grade B), with 43 or above earning a Grade A. Crucially, if you score 7 or fewer on the risk management section, you fail automatically regardless of your total. Part 3 uses exactly the same framework as the standards check that qualified instructors sit throughout their careers, so learning it well sets you up for the long term. For a full breakdown of the format and every competency, read our guide to the ADI Part 3 test, and you can rehearse the marking with our standards check grader tool, which uses the same competencies.

Do you have to pay to join the ADI register?

Yes. Once you have passed all three parts, you pay £300 to register as an ADI. Registration lasts four years, after which you renew for another £300, and you must maintain your standards through periodic standards checks.

Only when you are on the register and displaying your green badge can you legally charge learners for lessons in your own right. At this point you are a self-employed business owner, responsible for your own tax, insurance and diary. Passly’s instructor tools are built for exactly this moment: a digital diary, online booking, pupil records and finance tracking so the admin side of going solo does not swallow your evenings.

Can you get paid while you train? The trainee licence

Yes. After you pass Part 1 and Part 2, you can apply for a trainee licence (the “pink badge”) that lets you charge for lessons for up to six months while you prepare for Part 3. It is optional and comes with conditions: you must be sponsored by a training establishment, receive a set amount of ongoing training, and display the pink badge in your windscreen.

The trainee route lets you earn and gain real teaching experience before you qualify, which can sharpen your Part 3 performance. The trade-off is the cost and commitment of a sponsoring franchise, and the pressure of teaching for money before you are fully qualified. Many trainees prefer to wait, pass Part 3 first, and start clean. We weigh up both sides in detail in our guide to the PDI trainee licence.

How long does it take to become a driving instructor?

Most people take nine to eighteen months from starting study to joining the register. The variables are how much time you can commit, test waiting times in your area, and whether you pass each part first time.

StageTypical time
Preparing for and passing Part 11 to 3 months
Preparing for and passing Part 22 to 4 months
Preparing for and passing Part 33 to 8 months
Registering and setting up your business2 to 4 weeks
Total9 to 18 months

Part 3 is where most of the time goes, because teaching is a genuine skill that takes practice to build. Studying alongside full-time work naturally lengthens the whole process, so be realistic about the hours you can give it.

How much does it cost to become a driving instructor?

Budget for the fixed DVSA fees plus training, checks and a car. The fees are the same for everyone; the big variable is how much training you buy and whether you already have a suitable car.

ItemTypical costNotes
Enhanced DBS check~£50Required for the register
ADI Part 1 test£81Unlimited attempts
ADI Part 2 test£111Up to 3 attempts
ADI Part 3 test£111Up to 3 attempts
Registration fee£300Every 4 years
Training course£1,500 to £3,500Varies widely; pay-as-you-go or full package
Dual-controlled carVariesBuy, lease or franchise
Approximate total£2,500 to £5,000+Excluding ongoing car costs

Training is the biggest and most variable cost. Some trainees study largely independently for Part 1 and buy targeted in-car training for Parts 2 and 3; others buy a full package from a franchise. Cheaper is not always better: good Part 3 coaching genuinely improves your pass chances, and failing tests costs both money and attempts.

Should you go independent or join a franchise?

You can qualify and work through a franchise or set up entirely independently, and many instructors switch between the two over a career. A franchise provides a car, branding, insurance and often a stream of pupils in exchange for a weekly fee; going independent means lower overheads but you find your own pupils and sort your own car and admin.

There is no single right answer. New instructors often value the pupil supply and support of a franchise while they build up; experienced ones frequently go independent to keep more of what they earn. We cover the full trade-off, with a cost comparison, in our franchise versus independent guide, and you can model the numbers with our franchise cost calculator.

What comes after you qualify?

Once you are on the register, becoming an instructor turns into running a business. The teaching is only half of it; the rest is filling your diary, keeping pupils, chasing payments and staying on top of tax.

Your earliest priorities are usually getting pupils, setting your rates and getting your admin in order. It helps to understand realistic instructor earnings before you set prices, and to get your tax and expenses sorted from day one.

Frequently asked questions

What qualifications do you need to become a driving instructor?

You do not need formal academic qualifications. To become an approved driving instructor (ADI) you must have held a full UK or EU car driving licence for at least three of the last four years, be at least 21, be a fit and proper person (an enhanced DBS check), and pass the three-part DVSA qualifying process covering theory, driving ability and instructional ability.

How long does it take to become a driving instructor?

Most people take between nine and eighteen months from starting study to joining the ADI register. The three qualifying tests have waiting times and you can only attempt Part 2 and Part 3 a limited number of times, so pacing your preparation matters. Studying alongside a full-time job typically pushes the timeline towards the longer end.

How much does it cost to become a driving instructor?

The DVSA test fees are fixed: ADI Part 1 costs £81, Part 2 costs £111 and Part 3 costs £111, and registration on the ADI register costs £300. On top of these you should budget for training, an enhanced DBS check, and a suitable dual-controlled car. In total, most trainees spend somewhere between £2,500 and £5,000 depending on how much training they buy.

Can you earn money while training to be a driving instructor?

Yes, through a trainee licence, often called a pink badge. Once you have passed Part 1 and Part 2, you can apply for a six-month trainee licence that lets you charge for lessons while you prepare for Part 3, provided you meet sponsorship and training conditions. It is optional; many trainees choose to wait until they fully qualify instead.

How many times can you take the ADI tests?

You have unlimited attempts at the ADI Part 1 theory test. For both Part 2 (driving ability) and Part 3 (instructional ability) you get a maximum of three attempts each within the two-year qualifying period that starts when you pass Part 1. If you use all three attempts or the two years run out, you must start the whole process again from Part 1.

Do you need a special car to be a driving instructor?

Yes. To teach learners you need a car fitted with dual controls (a second brake and clutch for the instructor), and it must meet the DVSA's requirements for the Part 3 test and for tuition. Many new instructors lease or franchise a ready-equipped tuition car rather than buying and converting one, which spreads the cost and includes insurance.
