Replying to leobelle here since the thread got too deep.
I agree that learning to program is individual, but you don't learn to program in grad school. If a school gave you an MS and you can't do Fizzbuzz, that school isn't serving its signalling purpose (that I mentioned in my first comment). So while that school may be fine, if lax, if the employer is using education as a signal, a school that doesn't fail students doesn't provide a strong signal.
Relating to your comment about needing to see more code, education is actually perfect for that. Most companies don't let you take your source code with you, schools do. So provided you took some courses that required significant engineering projects, a student has a big pile of (hopefully) reasonably-designed code to show off to an interviewer. A person who worked for a less-than-progressive company (since some maintain open source libraries and such) does not. They both have their open source contributions.
