ADI part 3 test: teach the pupil, not a rehearsed performance

The ADI part 3 test assesses your ability to teach. In Great Britain, an examiner observes a client-centred lesson after you have passed part 2. The official benchmark is the national standard for driver and rider training. Part 3 overview.

A polished speech is not enough. Preparation should help you understand the pupil's needs, choose useful goals, manage risk and adjust your teaching when the lesson unfolds differently from your plan.

Know the observed-lesson format

DVSA describes a lesson lasting about 45 minutes, with the pupil driving for around 40. Initial discussion of goals and risk management should take no more than three minutes, with no more than three minutes for reflection at the end. Seventeen competencies are assessed across lesson planning, risk management and teaching and learning strategies. Official test format.

Those timings encourage a focused lesson; they do not justify rushing a pupil or continuing an unsafe situation. You may stop safely to give immediate feedback. The assessment is not an invitation to ignore a problem so that a planned route can be completed on schedule.

Use timed practice to notice whether explanations are proportionate. If an opening discussion consumes a large part of a lesson, ask what the pupil actually needs to know before starting and what can be explored more effectively through suitable practice.

Choose an appropriate pupil

The pupil may be a partly trained learner, fully trained learner or full licence holder. They cannot be an ADI or someone preparing for part 3. A partly trained learner should be able to drive for 40 minutes without frequent stops. The official what-to-take guidance also specifies the car and identification requirements.

Choose someone whose current learning needs you understand. Do not select a person solely because you expect a fault-free drive, then struggle to identify anything useful to teach. Equally, do not put an unsuitable pupil into a demanding setting just to display your intervention skills.

Discuss the arrangement with them honestly. Explain the examiner's presence and the intended lesson without asking them to perform a scripted sequence. A learner who feels responsible for securing your qualification may be distracted from their own driving.

Agree a meaningful goal

“Do roundabouts” describes an activity, not necessarily a learning goal. A more useful discussion identifies what the pupil finds difficult and what improvement might look like: recognising information earlier, choosing a safe opportunity or explaining a decision independently.

Match the planned route and task to that need. If a pupil requires time to understand approach observations, an unnecessarily complex environment may create overload instead of productive practice. If the task is already secure, repeating it without a new purpose may reveal little about teaching.

The national training standard is the official reference. Use it with your trainer to evaluate practice lessons; the examples here are planning suggestions, not a substitute scoring scheme.

Plan a lesson that can change

Prepare alternatives for traffic, roadworks or a pupil progressing differently than expected. A flexible plan has a clear aim but does not depend on one exact junction being available at one exact minute.

For example, suppose a pupil's difficulty initially appears to be judging gaps, but discussion reveals they are unsure which direction they are turning. The next useful action may be clarifying information and reducing task complexity, not repeatedly instructing them to choose a gap faster.

Notice whether your adaptation solves the actual problem. Changing locations without changing the explanation may simply move the misunderstanding elsewhere. Conversely, a brief safe stop and focused discussion may make the remaining practice much more useful.

For planning discussions, our Shrewsbury guide shows why a destination's access arrangements may change, while the Derby guide distinguishes bus-lane access from lawful stopping. An instructor can use these as examples of different learning needs without taking a pupil into an unsuitable environment or treating visitor parking as an authorised practice site.

Keep risk management active

Agree how support will work and remain alert to what is happening, rather than assuming a confident pupil will manage everything. Questions and coaching should fit the driving situation; an interesting discussion is not worth distracting somebody at a critical moment.

In practice debriefs, ask when you first recognised a risk, what information you used and whether your response was timely. Do not evaluate an intervention solely by whether the final outcome happened to be harmless. The aim is reliable judgement, not luck.

The result rules make risk management especially important: a score of seven or less in that category means failure, as does the examiner stopping the lesson because of danger. Official result guidance.

Make feedback specific and usable

Compare “That was poor” with a discussion identifying what the pupil noticed, what they missed and what they could try next. The latter creates a practice task. Ask for their understanding rather than assuming a nod means the explanation has been absorbed.

Avoid turning every exchange into a question when a concise explanation or immediate safety instruction is needed. Equally, do not answer every question yourself before the pupil has had a reasonable chance to think. Work with your trainer on choosing a suitable approach for the person and situation.

At the end, invite a brief reflection tied to the goal. A useful summary identifies evidence of progress and one next step. It need not claim that a skill is fully mastered because one attempt went well.

Use the result responsibly

The official grade bands are 31–42 for B and 43–51 for A; 0–30 is a fail, subject also to the risk rules. A third failure has consequences for the qualification process and invalidates trainee paid-teaching permission. Read the complete result requirements, rather than relying on a score alone.

If further preparation is needed, turn the report into specific work with a trainer. If you pass, complete the required registration stage before presenting yourself as an authorised ADI. Our qualification timeline explains the distinction.

Keep the jurisdiction and business steps separate

This is the GB assessment. Northern Ireland candidates should follow DVA guidance. For the earlier practical stage, see ADI part 2.
