I think we’re in the minority around here, but I’d like to see something like a bar exam for professional developers, too. The immediate benefit is that I don’t have to waste time proving that I know how to program a computer over and over again and you don’t have to waste time checking, but it would also be incredibly helpful to know that my coworkers have also passed it, so I know what I can assume they already understand, and what I might need to explain. Of course, I've always been a good test-taker, so maybe I'm biased.
