If I could add to this debate, from the view point of an IAM Examiner?
It has never seemed fair that if I Test two candidates on a given day & one does “just enough” to pass, whilst the other is a “riding God”, to quote Richard Hammond, they both just get the same “Pass”.
The IAM have at last done something about it, in that the top riders, & I personally think we’d be talking less than 10%, will get recognition of that fact, by being awarded a "F1rst" pass.
It’s also always been said that “If you join RoSPA, you have to re-Test after 3 years”, which is indeed true, but any IAM member has always been able to undertake a voluntary re-Test, & many do, particularly motorcyclists, as opposed to car drivers.
To be blunt, with over 100,000 members, the IAM couldn’t cope with some 35,000 re-Tests a year, but I think the chance to aim for the F1rst pass will motivate more than a few to come back for a further Test.
