I Failed ADI Part 3. What Should I Do Next?

Q: What if my trainer says I was just unlucky?

Luck and circumstances can affect any individual test, but ‘unlucky’ is not enough on its own. Ask what evidence supports that conclusion.

Q: Should I change instructor trainers after failing Part 3?

Not automatically. An unsuccessful result does not prove your trainer is poor. First, look at how the trainer responds and whether they help you examine the lesson honestly.

Do not rush straight into another test.

Start by understanding what happened, what the result does and does not say about your teaching, and what needs to change before you use another attempt.

Failing ADI Part 3 does not erase the skills or experience you already have. It means the lesson assessed on that attempt did not meet the required standard.

Your next step is not to start again from nothing. It is to examine the evidence, identify the areas affecting your performance and decide whether to progress with your current approach or pivot to something different.

How common is it to fail ADI Part 3?

It is more common than passing.

A Freedom of Information response from the Driver and Vehicle Standards Agency showed that, in 2025, the national ADI Part 3 pass rates were:

19.8% for first attempts
27.8% for second attempts
33.9% for third attempts

This means most tests in every attempt category during 2025 did not result in a pass.

The FOI request was submitted by Craig Preedy, co-founder of Instruct IQ. It asked DVSA for the number of first, second and third attempts and the pass rate for each category between 2021 and 2025.

ADI Part 3 pass rates by attempt

DVSA provided the following figures:

ADI Part 3 pass rate by attempt and calendar year
Calendar year	First attempt	Second attempt	Third attempt
2021	31.1%	31.3%	36.5%
2022	31.2%	36.2%	40.7%
2023	25.9%	34.7%	39.6%
2024	23.1%	29.0%	37.4%
2025	19.8%	27.8%	33.9%

The number of tests also increased considerably:

ADI Part 3 number of attempts by calendar year
Calendar year	First attempts	Second attempts	Third attempts
2021	1,282	841	881
2022	2,445	1,816	1,163
2023	2,802	2,131	1,492
2024	3,401	2,479	1,581
2025	4,498	3,468	2,287

The figures provide useful context after an unsuccessful result. You are not an unusual exception and a fail does not prove you are incapable of qualifying.

They should not be used as an excuse to dismiss the result either. Each attempt is limited, and the next one should be supported by better evidence than hope or reassurance.

What does failing Part 3 actually mean?

It means your performance during the assessed lesson did not meet the standard required to pass.

It does not automatically mean:

you are a poor instructor
you have learned nothing
every part of the lesson was ineffective
your pupil learned nothing
you need to replace your entire way of teaching
you will fail the next attempt
you cannot become an ADI

It also does not mean the result should be ignored because it was only one lesson.

The test provides evidence about your performance. Your task is to understand that evidence accurately enough to act on it.

What should I do immediately after failing?

Give yourself enough time to move beyond the initial emotional response.

You might feel disappointed, embarrassed, angry or convinced that one moment ruined everything. Those reactions are understandable, but they are not yet a useful analysis of the lesson.

As soon as you can, record what you remember:

What goal did you agree with the pupil?
Why was that goal appropriate?
What did the pupil already understand?
Where did risk begin to develop?
What did you notice at the time?
How and when did you intervene?
What questions or explanations did you use?
How did the pupil respond?
What changed from your original plan?
What feedback did the examiner provide?
What did you recognise only after the lesson?

Write down events before your memory becomes shaped entirely by the result or by other people's interpretations.

The purpose is not to prepare a defence. It is to preserve enough detail to examine what happened.

How should I use my Part 3 result and examiner feedback?

Start by separating the score from the lesson.

The score identifies areas where the examiner did or did not see sufficient evidence. It can help direct your attention, but the number alone cannot explain every decision that created it.

For each area of concern, ask:

What was happening with the pupil at that point?
What did I notice?
What decision did I make?
How did that decision affect safety or learning?
Was this an isolated event or part of a wider pattern?
What could I have done differently?
Why might that alternative have been more effective?

Avoid reducing the feedback to a new rule such as:

“I need to ask more questions.”

The useful question is whether a question would have helped that pupil think, understand or take responsibility at that moment.

More questions are not automatically better. More instruction is not automatically worse. The effectiveness of your input depends on the pupil, the risk, the goal and what is happening in front of you.

Should I book another Part 3 test straight away?

Only if you understand what affected the previous result and have evidence that the relevant areas are now stronger.

Booking quickly may be reasonable where the problem was narrow, clearly understood and not part of a repeated pattern in your normal lessons.

It may be better to wait if:

you do not understand why you failed
your explanation is simply that you had the wrong pupil
the same weaknesses appear in several lessons
you are trying to memorise a better test performance
you have changed your behaviour but do not understand why
you have not tested the changes with real pupils
your trainer cannot explain what evidence shows you are ready

Another booking gives you another opportunity to take the test. It does not create development by itself.

What should change before my next attempt?

That depends on the reason for the result.

You may need to develop one particular area, such as recognising risk early enough, agreeing a meaningful goal or allowing the pupil greater responsibility.

You may instead discover a wider pattern. For example:

planning the subject before understanding the pupil
asking questions without a clear purpose
waiting too long to manage developing risk
intervening whenever silence feels uncomfortable
completing too much of the pupil's thinking
continuing with an approach after it has stopped helping
giving feedback without checking the pupil's understanding
focusing on the test criteria more than the person learning

The next step should match the problem.

Do not rebuild the entire lesson when one area needs development. Do not treat a repeated pattern as a minor test-day mistake either.

Do I need more training after failing Part 3?

Possibly, but the number of hours is not the most useful starting point.

Ask what the training needs to achieve.

Useful post-test development might involve:

reviewing the result alongside a detailed account of the lesson
observing how the same pattern appears in normal teaching
trying a different approach with a suitable pupil
watching or discussing another instructor's decisions
examining a lesson recording where lawful consent and appropriate safeguards are in place
working with a different trainer for another perspective
improving the quality of your own reflection

Five more hours repeating the same approach may add very little. One focused piece of development can be more valuable if it identifies the actual issue and helps you change it.

Training should make your decisions more informed. It should not make you more dependent on someone telling you what to say next.

What if my trainer says I was just unlucky?

Luck and circumstances can affect any individual test, but “unlucky” is not enough on its own.

Ask what evidence supports that conclusion.

Which parts of your performance were consistently effective?
Which concerns were specific to the test lesson?
Have the same concerns appeared in previous training or normal lessons?
What would your trainer expect to see before recommending another attempt?
What, if anything, should you change?

A supportive trainer does not need to agree with every part of the result. They should still help you examine it honestly.

Reassurance without analysis may feel helpful for a day, but it does not prepare you for another attempt.

What if my trainer said I was ready but I failed?

Being considered ready does not guarantee a pass. A test assesses the lesson delivered on the day, and real lessons do not follow a fixed script.

However, readiness should be supported by evidence.

Ask your trainer:

What were you seeing consistently in my lessons?
How was my readiness assessed?
Did my test result reveal anything that had appeared before?
Was something important missed during training?
What will we do differently now?
How will we decide when I am ready to try again?

The conversation should not become an argument about who was wrong.

You are trying to understand whether the preparation was sound, whether the test exposed a gap and what needs to happen next.

Should I change instructor trainers after failing Part 3?

Not automatically.

An unsuccessful result does not prove that your trainer is poor. It also does not mean you must remain with the same trainer regardless of what happens next.

First, look at how the trainer responds.

Do they:

help you examine the lesson rather than blame you or the pupil?
connect the result to evidence from your previous development?
explain their reasoning?
adapt the training to what the result revealed?
acknowledge anything they may have missed?
encourage you to develop your own judgement?

You may benefit from another trainer's perspective even if you continue working with your existing trainer.

Different feedback is not automatically conflicting feedback. Two trainers may describe the same underlying issue in different ways or suggest different approaches that could both be appropriate.

Ask why. Understanding the reasoning is more useful than searching for the trainer who gives you the simplest answer.

If you are teaching on a trainee licence, check the DVSA rules, your training agreement and any franchise or sponsorship commitments before changing training establishment.

What should I do after failing my first Part 3 attempt?

You still have two permitted attempts within your qualifying period, but that does not mean the first result should be treated as a practice run.

After a first fail:

record the lesson while it is fresh
examine the result with your trainer
identify whether the concerns were isolated or repeated
agree specific development priorities
apply them during normal lessons
gather evidence before deciding to rebook

Do not respond by trying to fix every competency at once. Find the decisions and behaviours that had the greatest effect on the lesson.

What should I do after failing my second Part 3 attempt?

Pause before using your final permitted attempt.

The stakes are now different, but panic will not improve the quality of your preparation.

Review both test results together. Look for patterns:

Are the same competency areas appearing?
Are different scores being caused by the same underlying decision-making?
Is your teaching effective in normal lessons but changing under test pressure?
Are you relying too heavily on one pupil, route or planned subject?
Has the training approach genuinely changed between attempts?

This is a sensible point to seek a second opinion if you have not already done so.

Another trainer should not simply give you a new script. They should help you test the assumptions behind your current approach and identify what the existing evidence may be telling you.

Use the third attempt when you can explain what has changed and demonstrate it consistently, not simply because time is passing.

What happens if I fail Part 3 three times?

You cannot take another Part 3 attempt within the same qualifying period.

The ADI qualification process operates within two years of passing Part 1. If you do not complete the required tests within that period, you must start the qualification process again.

Failing a third attempt is a serious setback. It does not remove the teaching experience, knowledge or development you have gained.

If you decide to begin again, do not simply repeat the same journey.

Examine:

what the three results have in common
whether your training addressed the underlying issues
how your normal teaching compares with your test performance
what a different development plan would need to include
whether becoming an ADI remains the right goal for you

Starting the process again should be an informed decision, not an automatic reaction made while disappointed.

Does a higher pass rate on later attempts mean I am more likely to pass next time?

Not necessarily.

The FOI data shows that second and third attempts had higher pass rates than first attempts in every year provided. It does not prove that taking another test causes a candidate to improve.

Candidates reaching later attempts may have gained more experience, completed further training or changed their approach. The groups may also differ in other ways.

The figures cannot predict your individual result.

What matters is what changes between your attempts and whether those changes improve the pupil's learning and safety.

Do the figures show how many PDIs eventually qualify?

No.

DVSA was asked for the proportion of candidates who eventually passed within their permitted attempts and the average number of attempts taken by successful candidates.

It declined to provide that information under section 12 of the Freedom of Information Act because producing it would exceed the statutory cost limit.

DVSA explained that candidates can reapply and begin the process again. It would need to examine individual records manually to identify each person's qualifying period and eventual outcome.

It estimated that reviewing one year's applications alone would require more than 700 hours of work. The applicable FOI limit equates to 24 hours of staff time.

This means the first, second and third-attempt percentages cannot be added or multiplied to calculate an overall qualification rate.

They are calendar-year test figures, not one group of candidates tracked through the entire process.

How can I rebuild confidence after failing Part 3?

Do not make confidence the only goal.

You can feel confident without being ready, and you can be capable while feeling shaken by a result.

Build confidence through evidence:

identify something you already do effectively
choose one specific area to develop
practise it in an appropriate lesson
examine what changed for the pupil
repeat it in different situations
ask for focused feedback
record the evidence of improvement

Replace “I am not good enough” with questions you can answer:

What happened?
What did I understand correctly?
What did I miss?
What pattern can I see?
What can I try next?
How will I know whether it worked?

Confidence built from understanding is more useful than trying to persuade yourself the result did not matter.

How do I know when I am ready to try Part 3 again?

You should be able to see evidence in your normal teaching, not only during rehearsed test preparation.

You do not need perfect lessons. You should be able to:

identify the pupil's needs and agree an appropriate goal
adjust the plan when new information appears
recognise and manage developing risk
select a suitable level of instruction or support
give the pupil space to think where appropriate
intervene when they need you
help the pupil understand their progress
reflect accurately on your own decisions

Most importantly, you should understand why you are making those decisions.

Readiness is not memorising what an examiner wants to see. It is being able to work effectively with the pupil you have, in the lesson that actually develops.

What should I take from the national pass rates?

Part 3 is difficult, and failing is common.

In 2025, most first, second and third attempts did not result in a pass. That should challenge any suggestion that qualification is automatic or that one fixed teaching method can reliably get everyone through.

The figures should not be used to frighten you, sell unnecessary training or suggest your attempt number determines your future.

Use them as context.

Then return to the evidence that matters most: what happened in your lesson, what you understand now and what you will do differently next time.
