Standardized testing will quickly get subverted, with people "studying for the test." It's almost a theorem that any proxy for assessment will become subverted, with people passing the test without actually possessing the necessary underlying skill. In math people keep complaining about "teaching to the test" and that people pass the tests, and yet don't have the skills. Same will happen if you try to standardize computer recruitment. Hasn't the industry effectively done that already? Doesn't the fact that almost anyone of reasonable ability[1] can pass an interview after studying something like Cracking the Code Interview indicate that you can successfully "study for the test"? [1] I am assuming that, even when "teaching to the test", a certain amount of baseline ability is still required to actually pass.
