By removing any kind of formal authority by them. They should be places to learn, not a bureaucratic machine for deciding who is "worthy" and who is not. There could be another organization that specializes in knowledge verification and certification. But that should be completely independent of learning. Of course, now the question becomes "how do we prevent a verification and certification authority from abusing their power?" - but that question is not particular to this context and can be applied to any human organization of any kind. However, in this particular case, I think that employers would be the verification authorities themselves. They are the ones that need the real-world knowledge, so they should be the ones to measure it.
