Worse, some school systems require teachers to accept student work at any time. I have teacher friends who tell me stories about students who don't do anything all semester. Then in the last week, somehow all the work gets done and submitted, and it's all passing. Obviously what's happening is the parents are doing all the student's work, and the teacher is forced to pretend it's genuine.

Then there are the systems which only teach "theoretical" work. I had a student who said he could program, passed a bunch of classes called "programming in C++" and such, only to learn he hadn't written a program ever -- he had just been taught the theory of writing a program. It's like taking calculus but never doing an integral.
