I too share your worry that it's seems to trend towards the European model... reminds me of conversations I've had with
@devon deer about what it takes to be allowed to do an unguided hunt in the UK. Honestly the parallels are striking.
Firstly
@JLS I will sign up for for a Jagermeister, I quite like that drink

I think you mean the German Jagdschein
I'm not sure I can add anything really as we don't have any Public land.
But, as all our available land for hunting is privately owned, and we have the strictest gun control in the world, I can add the following.
The most important education to me was hands on, out in the field, and provided by an older wiser guy than me, a local gamekeeper.
In 1998 a new company was formed and decided they would bring out a basic exam (Deer Stalkers Certificate Level1), mainly theory and classroom based, followed by a field test and shooting exam, completely voluntary, as it is now, for the time being I suspect.
In 1999 I signed up for the weekend course, (as I was a hunting guide I thought why not) to me it was fairly easy, but I did learn a few things, but a lot of fellow hunters on the course thought it would open up doors to them with private landowners, well they got that wrong, even today it doesn't really open any doors.
However, the course attracted the attention of our authorities who issue our firearms licences, basically our police force, and since then some police forces (not all, and also not a condition of our Governments guidance on issuing a firearms licence) insist (wrongly) that new applicants must have completed the course (they basically try it on as they don't really want us to have guns!) but I can see it going that way eventually, there are some real idiots out shooting in the UK, but thankfully they are in the minority.
Then, they decided why not bring out a practical based certificate DSC Level 2, basically you are 'witnessed' stalking and culling a deer on 3 separate occasions.
This is where I get a little annoyed for my fellow hunter, I did the L2 for the same reason previously stated, I didn't do it prove anything to anyone, but in the UK we have a publicly owned area known as the Forestry Commission, I have no interest in hunting it, but there is a condition of hunting it, you must have a L2 certificate, which to some can be financially out of their means, see where this is all going?
Its when the authorities get involved that it can have implications for hunters, I'm not saying that is where the Master hunter course would go, after all you have the 2nd amendment, we don't!
What I will say is, a new hunter in the UK, who doesn't have access to an experienced guy like I did it will help them and educate them, but it has it's limitations, however if it means one less idiot running around blasting at deer willy nilly in the UK then it's fine with me.
Sorry this was a bit long winded!
Cheers
