In the US, in the public schools, they teach evolution. That doesn't stop local school board from trying to slip Intelligent Design into the schools disguised as science. These cases lose when pressed in court. They are insidious and always looking for trickly ways to introduce the ideas into the science class. I think some Texas schools put a sticker inside their text books claiming that there are alternative theories (no valid alternative theories at the point). I would have to look it up, to give better details though.
As far as those faith-based schools here, apparently freedom of speech means parents have the right to keep there children in pure ignorance. A family member was very proud that she found a Christian school that does not even have the word Evolution in the text books. It made her glow with happiness. What a tragedy.
