Just asking a leading question here, but what if there was a website where people who have attended survival schools could post reviews?
You're asking for a reviewing process. Naturally there is value to something like that, but we'll need people who can evaluate the knowledge being taught, the quality of instruction, and the cost of the course compared to other similar courses. Alas, people who can do this are usually not students who might take the course, and this is the problem with consumer reviews.
Consumers tend to evaluate based on their experience: did they *feel like* they learned something useful, did they *feel like* the course was worth their money. When they're complete beginners, it's hard for them judge: did they learn good stuff, and did they get enough of it for the money. They could potentially be mislead by instructors who can give them a good experience without giving them good knowledge.
I think we keep running into the problem of industry standard.
