The taxidermy industry is no different than any other. Does a painter orcarpet cleaner or landscaper have to "certified"? The market takes care of itself. A customer that got a crappy mount would have the same recourse as any other customer of any other industry. If you are unsatisfied with it, you could refuse to pay and even sue for damages and loss. A bad taxidermist would gain a bad reputation and suffer for it. Just because a guy would be "certified" means nothing as far as a guarantee. I bet there were many people who took the exam and presented mounts that they did not do. I bet there are many mounts in any given year from "certified" taxidermists that have the hair fall out. As a matter of fact, hair slip is usually the fault of the hunter in not properly caring for it before the taxidermist even sees it. As in any other transaction, a hunter should research his purchase before committing to it. (ie, seeing samples of work, references, reputation etc.)
