MrHappy:
Afternoon DD.
My opinions are based on no facts, it is purely opinion. I am of this opinion because I feel that as a potential vocational licence holder, one has to accept that before any training is undertaken, there will be a practical examination at the end of any course. An instructors resonsibility is to ensure that a candidate is suitably trained to take said examination. Anybody wishing to drive a heavy goods/public service vehicle should be aware that the risk to life, limb and property is far greater whilst in control of one of these vehicles and, as such needs to demonstrate a degree of skill to an examiner for only one hour. As a car and motorcycle user too, I realise that accident/mortality rates are no doubt higher in these vehicles, but that is surely due to the fact that as professionals we are aware of our greater responsibility.
I can’t argue with that. 
MrHappy:
I fully accept that people will learn at different speeds and some will suffer terribly from test nerves, however as I stated, its not as if the test on day 5 or whatever comes as a surprise, so having known from the outset that you will have to show that you can put into practice what you have learned, surely each candidate that takes a test is in a proper position to do so.
As an ex-LGV instructor (I only did that for a couple of years though) I’ve seen candidates who were assessed as ‘ready for test’ go completely to pieces upon arrival at the test station on test day.
Yes, I agree that the test date is known in advance.
We would use various routes during training in order to get the candidate thoroughly familiar with the vehicle and traffic conditions. As part of familiarising the candidate with the situation they face, we’d even take them to the test station so they could see other candidates performing their off-road exercises. As much planning, preparation and practice as possible was utilised, but in spite of this, some candidates still failed. IMHO, this will continue to be the case due to the fact of randomness.
I’m afraid to say that learning, and the retention of learning, for practical subjects is not an exact science once the randomness of test conditions is taken into account.
MrHappy:
I’m by no means a newbie basher, but the amount of test failure excuses that you see and hear of is ridiculous. “I was going well until that stupid car driver pulled out on me.” Its our responsibility, is it not, to think for others as well as ourselves? “The weather was atrocious,” good luck finding a job that only requires you to drive in the sunshine. We all make mistakes as qualified drivers and i’m certainly no exception to that, however, my point remains that regardless of how quickly you’ve learned, if you’re taking a test, you only need to show for that one hour (is it still about an hour?) you can drive the vehicle in the manner prescribed by the DSA. Is that too much to expect?
I can agree that in extremely rare cases, there are some candidates who might not be suitable for passing a test for a vocational driving licence. Reasons for test failure can only be given on the form available to the driving test examiner, which means that mistakes/errors/inadequacies must be pigeon holed to fit the form. The real reason for a candidate’s inadequacy in a driving test might be due to a disability not yet identified in a candidate.
For example, a candidate might have minor sight defects, such as restricted peripheral vision, restricted depth of vision, poor 3D perception or simply poor coordination skills.
Then there are candidates who may not be aware that they might suffer from one of the many recognised learning difficulties.
IMHO, a one-size-fits-all approach such as limiting the number of driving test attempts would be discriminatory to those with disabilities which are insufficient to disqualify them from seeking an LGV licence.
MrHappy:
As i said, I have based my opinions purely on my own thoughts, not facts and I certainly didn’t go through any process to arrive at them. I know many people will disagree, but then hey, it wouldn’t be such a good forum if we all agreed with each other.
Of course you went through a process to arrive at an opinion, because to say otherwise would suggest that you made the whole lot up at random, which I doubt. 
IMHO, you’ve put forward some great discussion points that got my attention!! 
MrHappy:
By the way, i’m not anti training companies either, I think there are some around with questionable ethics as to putting unprepared candidates up for test and copping some re-training fees, but that was not the purpose of my OP and I hope nobody thinks for a minute that it is. The point of the post was to discuss whether a limit to the number of tests was practical.
Of course there are some training companies with questionable ethics, becase there are bad apples in every barrel. However, it’s fair to point out that (to most training companies) a day or two of retraining and a retest can be less profitable. I’ve never run a training company, so I’ll leave that question to those who could give you a better answer to it than any guess I could make.
