It all depends on the bias of the teacher... in america, something like 40% believe in a litteral 6 day creation less than 10,000 years ago. Those numbers aren't significantly different in grade school or high school teachers. There are schools in america right now that flat out don't teach evolution... They skim by it on the day... say "ok class, if you want to read up on evolution it's on page x-y on your text book... I will not test you on it just check the box saying you read it and you are golden.
I myself was raised creationist.... when you actually hear the creationist arguements etc... as a 4th grader, they actually sound pretty logical. They really take about a high school level education to see through, and I never really confronted the facts again after 4th grade, it wasn't until I was in my 20's that I looked back and realized how much bull it was.
