So in my opinion we need a test away from the shooting organisation and set by government.
Oh my Lord!! What a monumental cock-up that would be!
Doubtless they would commission a group of very expensive consultants to define the perfect shooting test, completely ignoring those with expertise and experience.
They would then engage some highly-paid KC's to evaluate potential risks, determining that there are no suitable ranges in the country that do not endanger the public so a new one will have to built. It will be commissioned to be built somewhere completely inaccessible to the vast majority of the shooting population.
They will then let a tender for constructing the necessary range and award it to the lowest bidder. After numerous problems during construction it will finally come on stream three years late and at five times the original budget (or six years late and ten times the budget for the Scottish range)
For the test itself they will insist you can use only one brand of bullets, regardless of calibre. These are prohibitively expensive, but since there is only one supplier they have you by the proverbials. Home loads will be strictly verboten.
The assessment will be run by jobsworths with an inflated sense of self-importance and zero experience of firearms. They will be given some ridiculous job title such as Primary Range Assessment Technicians or Theoretical Weapons Assessment Technicians. They will insist that they work from home, so the range will only be open on Tuesdays and Wednesdays (Bank Holidays and Religious Festivals excluded). After six months of operation they will go on strike for improved terms and conditions. When this is awarded they will depart on long-term sick leave claiming stress.
If will take you six months to book your test, and when you turn up they will ask you why you are there, and didn't you receive the letter telling you that your test had been postponed until after Christmas? Because of the backlog your current annual certificate expires before you can take the test, meaning you have to pay to lodge your firearms with a Dealer.
Once you eventually get to take the test then the award certificate will come through with someone else's name and details printed on it. No-one will ever ask to see it.
Two years later the database will be hacked, and the details of every Firearms Certificate holder will appear on the Internet.
