Creationism endorsed by UK education agency?

This article in The Guardian caught my eye this week.
The UK, in common with other countries, has an agency that attempts to assign uncommon or international educational qualifications a UK equivalence. This is obviously a useful and sensible thing - until, that is, you equate an exam which contains questions blatantly at odds with established scientific fact. Then, you give credence to the qualification and the underlying beliefs, both at home and abroad. More worryingly, this curriculum is being taught to kids in Britain, taught outside of the state system, either at private christian academies or through home schooled initiatives. This got me thinking - what controls are there on the quality and nature of education for the home schooled? We have a loophole in our educational system at present which allows for parents to withdraw them from state education and warp minds with absurd propaganda. Its time we changed this. Germany outlaws home education - we should do the same.
