I'm with Sapper on this. I can see it more in the Civil discipline, but cars, computers and space shuttles aren't designed by PE's, so why should the person teaching you how to design cars, computers and space shuttles have to be licensed?
Something to keep in mind: even though a state might not have a specific exemption for industry, a de facto one exists. I'm not a lawyer, but the way I understand it is interstate commerce is regulated (under the Constitution) by the federal government. So a state cannot regulate a product you make in that state if you sell it in other states. A state may regulate what is sold within it's borders, but not what is sold in other states. So, for instance, Michigan could say "Any car sold in Michigan has to be designed by a PE", but not "Any car designed or built in Michigan has to be designed by a PE"--only the federal government has the power to do that, and they haven't. Before I get flak for this, I'm not saying I agree with it, it's just the way it is.
And, BTW, I took the EE PhD. qualifier exam at Michigan Tech and it was a helluva lot harded than the PE exam. OTOH, the qual is not a standardized test.
