If you got together an "independent training consortium" of EBME departments that could provide training placements then I suppose you'd have venues to do the hands-on stuff and provide wider-ranging experience.
What you're suggesting could be supported via distance learning, i.e. training packages and web-based materials such as presentations and lectures. You'd need individuals to come up with that sort of stuff as well as mentoring I guess.
If this were supported by proper training planning plus the other training stuff, described above, and was of reasonable duration with acceptable content, in terms of depth and breadth, then it'd most likely turn out individuals with valuable skills that are in demand.
It'd probably be useful to target some academically biased individuals who are trained in adult education, for example, to give credibility to the specialist course material and theoretical stuff, in addition to the ONC in electronics, at some stage I reckon.
Giving the departments involved in the training "first-pick" of individuals coming through the scheme would be an incentive for them to get involved in training I guess.
In my view a single well-trained and motivated individual is better than pushing through lots of individuals that continue learning the basics when employed in working grades due to a lack of high-quality training.
How about offering your services as an IPEM training moderator to help oversee the vocational training that is currently going on around the country?
You could act as quality-controller and make a contribution that way, perhaps.
