Adding to Loudmouth's opinions, I can report what my younger daughter experienced in AP biology here in Podunk: the teacher told the class, "These three chapters {in Campbell's text} are on evolution, and you may read them if you want. They won't be on the test."
The teacher is a smart, pleasant guy who goes to the Primitive Baptist church, but I don't know his personal evo/cre leanings with any certainty. But I am quite sure that a genuine shitstorm would erupt if he actually required students to regurgitate anything about ape ancestors on a test. And yes, Texas high-school biology standards do require mastery of some evolutionary concepts. I don't know if questions about evolution actually get included on the exit-level statewide tests, though.
