I see lots of schools around different states and countries that teach wilderness skills and they seem to vary a lot in their basis (that is, what qualifies them to do what they do). Some are led by an organization with a handful or more paid staff, some are volunteer individuals, and everything in between. Some are qualified based on certifications, some are qualified based on 'I can do this well' and the latter often goes with X amount of time doing it as a qualification.
Looking at certifications, there are dozens of relevant courses that vary in time requirements, intensity, and geography. Some are just courses to certify you've learned certain skills, whereas others are geared toward pedagogy and not just learning skills but also teaching them. There are also separate certifications which make sense but aren't part of other 'wilderness skill instructor certifications', from wilderness first responder to forest therapy guiding. As a customer of a wilderness skills center, it wouldn't hurt for teachers to have those kinds of certifications, but certainly they aren't necessary.
Is there a standard or commonly accepted expectation in the wilderness skills community of what it takes to be an instructor? For example is it taboo to offer guided trips and courses on wilderness skills, having nothing but one's own experience as credentials? Is there a certain amount of years or specific skills that one is expected to have before teaching others in an organized and even for-money capacity? Or is it purely case by case, up to the opinion of customers whether an instructor is qualified enough or not? Mainly asking in the context of USA and Canadian wilderness skills schools and culture, trying to get a sense of how the wilderness skills community views qualification for people trying to lead a new thread in the community.
