This seems to be the first (or so it says).
There are a lot of opinions about the value of a course like this.
I dont know if I would want to go on a course run by:
a) someone who had little "actual" experience, but had been taught to teach
or
b) someone with worlds of experience, but who may struggle on the teaching side.
These are the extremes, and I am happy to say that most of the people that I have learnt from (not just in Bushcraft but my other passions) have been truly inspiring.
I think that some of the course contents would be very suited to people wanting to take groups outdoors - and the prospectus makes no secret of this. If you are taking kids on nature walks, or adults, think of the reaction you will get from others when you light a fire by friction, or demonstrate another of the amazing skills/arts that go with this subject.
The current system of "Bushcraft School owner interviews and checks out prospective job applicants" will not change - I hope. But the knowledge of the legal and other aspects - such as Risk Assessment - may well aid a candidate to rise above another if there are two on the short list.
As for a "Controlling Body", that is something that the current generation of teachers must decide on, as that is how these things usually start. I hope they decide on inaction. The thought of an "Institute of Bushcraft Teachers" makes my skin crawl, as my experience of these "clubs" in other industries and fields has often not been as positive as it could have been. Sometimes the level you reach has no bearing on your usefulness to the field.
The other end of the stick - I hope to do a Fisheries management qualification next year - I like fishing. Maybe I would consider a course like the one at Plumpton if it felt right and taught me more about one of the subjects that I love.
My opinion - hope I haven't offended.
