It's different in the US
Here in the US, schools are administered locally. Our constitution made no provision for a national educational authority and under the Tenth Amendment, the power to regulate education is left to the individual states. In fact, there are people who consider the existence of a federal department of education a violation of the federal constitution.
In the UK, it's apparently possible for a single group of sensible government ministers to put creationism and 'intelligent design" in their place...outside of the science curriculum. In the US, nationally-based lobbies are able to argue this non-issue individually and interminably in the legislatures of each of the 50 states and the thousands of local school boards. There is no one national-level authority that can settle the question, so the attack on the science curriculum will probably go on indefinitely.
