It's very touchy when you get into those areas. More than likely, where I taught I could have taught ID if I had wanted to and never gotten in trouble (because we were in a pretty fundamentalist area). However, I could also have gotten into big trouble. My personal feeling is that, I am a teacher, not their parent, and it's not my job to teach them what to believe. But, it could actually be quite the teachable moment, because the kids were keenly interested, but wanted to talk about GOD and the Bible.

You are correct not to bring the Bible into a high school science class. Those who want a "critical analysis" of evolution in high school have no idea what this would mean.
Among other things it would involve explaining how the age of the earth is determined, and how geologic strata are analyzed. There is no branch of science compatible with a strict, literal reading of genesis.
I do think, however, that it is cowardly for teachers not to provide a bibliography to students who are interested.
