Pass rates on driving tests, how the DVSA uses them for quality control

It’s a rumour as old as the hills, “Driving Test Examiners have to pass & fail a certain number of people in order to control the number of people on the roads”

Now I’ve never, ever seen evidence of that in any official capacity at all as a driving instructor

I’ve also, over 21years now, seen quite a few changes to the testing process, not to mention covid and all the disruption that that caused, and I’ve never seen the average pass rate for the country change more than 1 or 2 percentage points

In my previous work as a Design Engineer / Project Manager in the automotive industry, I know for a fact, that you can’t change any aspect of a product’s manufacture without seeing a change in it’s operating statistics, not even getting the same product from a different supplier – even that sort of thing changes performance (and that’s why supplying parts into the automotive industry involves so much testing and approving)

So this idea that you can take away one of the manoeuvres for example, and go down to just one reverse exercise rather than two, and not see a change in the pass rates doesn’t sit well with me at all, the engineer within me wants to say that it’s impossible!

When the DVSA made that particular change, they were keen to tell us in their communications that the pass rates remained the same in spite of the change. They say that they use that measurement as a way of gauging whether they have done something that makes the test easier or harder

They’ve also, over the years, explained that they use it as a way of making sure driving examiners are consistently marking the tests. If you take a fictitious example of an examiner being racist to demonstrate the point, pass rates of 90% for white people and 10% for black people would highlight this to management so that they could deal with it as they saw appropriate

So pass rates remaining the same help the DVSA to ensure that learner drivers are receiving the same level of scrutiny during their driving test. They collect and analyse data for test centres, test routes, junctions, manoeuvres, individual examiners and individual instructors and compare it to other performance indicators at both local and national levels

A local driving test centre manager once told a story of being involved in a car crash on a day off one day and then having to work hard on their return to work to avoid being too harsh on the learners taking their tests. They could see clearly that this was happening when compared to other examiners that were working at the time

These are good things of course, we want consistency in marking and we don’t want outside influences, attitudes or experiences pushing results either way

Individual driving test centres have differing pass rates when compared to national level for a lot of reasons, which are mainly geographic and social

For example, a quick Google search this afternoon shows that the test centre with the lowest pass rate in the country at the moment is Wolverhampton at around 33%

Wolverhampton is a busy city, with plenty of complex junctions and heavy traffic but it’s also an area with social needs. Unemployment is high, there are a lot of people living on benefits and money is tight. These things mean that people will have limited means to invest in professional driving lessons in comparison to other areas we could look at. There is also the question of immigration, with previous experiences, language, cultural issues affecting people’s performance in lessons as well as the tests

 

On the other side of the coin, the Isles of Scilly is where you have the best chance of passing your driving test, at around 88%

The two environments are very, very different!

All of this obviously needs to be offset against the standard required to pass a driving test

To boil it down, I’d describe that as being able to demonstrate that you can drive, reasonably smoothly and without assistance or advice, for 35-40 minutes around a test route containing a mixed variety of road and traffic conditions, showing good judgement in your interactions with other road users and a complete knowledge of the Highway Code

The key points there are the words “without assistance or advice” and “a complete knowledge of the Highway Code”

If somebody demonstrates these things, then they HAVE to pass a driving test and if they don’t, they MUST fail it, it’s as simple as that

And that means that to increase Wolverhampton’s pass rate to meet national averages, you’d have to introduce lenient marking, and you’d have to be harsh in the Isles of Scilly – neither are fair on others taking the test in other parts of the country and we must never compromise the UK’s road safety record

So, the final question remaining is this “if you take everyone to test, trained to the extent that they can easily meet the requirements of the test, is it possible that 100% of the people taking a driving test could pass it?”

My answer to that is no. Firstly, the DVSA measures instructor pass rates over a 12mth period, because we can very easily have good weeks (100% pass rates) and bad weeks (0% pass rates) and secondly, if I take 50 customers to test over that 12mth period, statistically, 20% of those are living with educational needs and mental health problems and it seems fair to say that those people will always find it harder to pass a test (the only way to avoid that is to discriminate and refuse to teach such people). Finally of course, anyone can simply make a mistake

But in principle, it is an objective for anyone presenting anyone for a driving test to make sure that that person is properly prepared and is capable of passing it and the best thing that a learner driver can do is to get a Highway Code and read it repeatedly until they’re almost quoting it word for word if they are asked to, and then to invest in plenty of training involving independent driving, focussing on having conversations with their instructor about what might change about the driving plan in different circumstances (such as if it’s raining)
