This article from the Sunday Times suggests that they are, though my guess is that it all depends on the question you ask.
Given that we cannot individually know even a small percentage of everything, it makes no sense that everyone should know the same thing, so even by their own standards of social engineering, (the intent behind today's schooling), the National Curriculum doesn't make sense.
And a final note...it makes much more sense that variety should be introduced into the system by playing to the different strengths of different learners. How best to do this? Autonomous education.
