Really? Almost all of the post-graduate CS students I've known are experienced people who went back to school because they were at the point where they needed to either move into management or become a very high-level expert.

That's only personal experience, however, and mostly out-of-date

That said, I would hope any of them would be a step up on the new programmers from the "churn 'em out" short courses many are forced to take as the only affordable way they have to get into the industry, but then are left with little knowledge beyond how to get the requirements fulfilled.
