you should be able to measure a need for a training course
You can! For some training courses the need is demand, pure and simple. I don't "need" to go on a training course on how to do stick-making, but I want to and I'm willing to pay, hence the training courses exist. For other training courses, the "need" is to ensure a minimum standard is met. That is what the DSC1 is designed for. Forget, for the moment, whether it is voluntary or compulsory, free or paid. I doubt, if you look at the syllabus, you'd find much fault with the content of DSC1, given it's stated aim.
DSC1 isn't a metric - it is a training course.
I know I'll be criticised for being a pedant (and not for the first time) but DSC1 isn't a metric
or a training course - it is a qualification, delivered via a training course and assessed via examination. It is, in DMQ's own words:
"DSC1 is a basic qualification for deer stalkers and managers. It is a largely knowledge based qualification which enables candidates to demonstrate their understanding of basic deer management principles and meat hygiene, and to show competence in shooting at simulated targets."
It doesn't claim to make people better stalkers, it enables them to demonstrate their understanding of what they've been taught. Again, looking at the syllabus, I'd hope we'd all agree that what is taught matches these aims.
As such, it provides a standard, rather than a metric, in that anyone who has passed a DSC1 has proven their ability to meet the required standard/pass rate to gain the qualification.
I've never seen any metric, or attempts to produce them, for deer stalking
Oh, I'm sure you have!

I know I'm taking part of a sentence in isolation, but......a metric is an analytical measure, so deer shot per outing would be a handy sort of metric for deer stalkers....and one often used by professional stalkers to express the likely level of success when taking out a client. A cull plan is full of metrics for deer stalkers - population density and age profile, fecundity, etc.
I think we also both agree that more knowledge and improved standards are a good thing and it is worth promoting that within the stalking community.
But isn't this exactly what DSC1 is designed to do - increase knowledge and improve standards? So is the argument really about whether DSC1, DSC2, etc are fit for purpose, whether they are necessary, what they cost, or whether they should be made compulsory?
Taking the DSC1, I would suggest that it is fit for purpose. I also think it is necessary because (a) there are laws relating to deer that should be adhered to, for deer welfare reasons if nothing else, (b) a lot of venison is put into the food chain, and (c) for the health & safety of the stalker and others. I agree that they shouldn't be compulsory, or at least not to the point that they are a pre-requisite to granting an FAC. As to cost, well that argument will never be settled
we don't know what we need
Which, again, is why DMQ exists! In their words, to maintain the standard of the DSC qualifications (i.e. to make sure they are fit for purpose), to quality assure the assessment process (i.e. to make sure all training courses are delivered the same way and meet the same criteria) and to administer the awards. The organisations they work with provide input to the standard, i.e. together they define "what we need". Who out there is better qualified??
I've said in the past that it is much better that we take on our own training and take responsibility for this rather than have a whole government department, for which we would have to pay, doing it for us.
I am interested as to who, exactly, is the "we" in this, if it isn't the organisations that support DMQ? Is there really some happy, well-intentioned, collective that exists in deer stalking to do all this for nowt? If so, they're damn well hidden!! Like any industry, if deer stalking can't self-regulate then it will be regulated.
our position must be that there is no evidence of a threat to animal welfare or public safety and, therefore, there is no justification for interference
I disagree with that statement. Every time someone goes out stalking there is - at least theoretically - a threat to animal welfare and/or public safety. As to evidence, what about notifiable diseases? Also there are, sadly, well-documented examples of other parties being shot by people out stalking - in one well-known case a father shot his own son. Both the above are thankfully rare, but they cannot simply be discounted as "no evidence".
I don't think you, MS and I are far apart at all, our differences are minor.
