So Ed Balls is going to force kids to have sex education whatever their parents think. When will these centralisers ever learn. I am not going to get into the merits or otherwise of sex education. I don’t need to. Because the truth is that you can’t and shouldn’t seek to impose your ideas from the centre. Every head teacher should have the power to run his. School as his professinal judgement dictates. And if parents want to give their own sex education or not that is their fundemental human right.
