This is kind of how I feel too. I agree that a college degree may not be a good indicator of skills. But is the solution really more standardized testing? The data on standardized testing is pretty clear: It leads to teaching and learning to the test. Which is great if the test encompasses absolutely all skills and knowledge that people are supposed to have, but that's not the case.

People need to give up the idea that it's easy to evaluate people. It's not, you can't just look at some one-dimensional number. (Be it GPA or some certification score.) If you want to really know their strengths and weaknesses, you need to get to know people.
