My loathing of experimental teaching methods that failed generations of children, my fear of disruptive children wrecking the education of those who want to get on and learn, my contempt for the 'all must win prizes' mentality - whether in sporting or academic endeavour - is not just political, it's personal. And that leads me to the first group of critics, who want to hear positive, constructive policies from my party. They will not be disappointed.
When I say I want 'zero tolerance of disruptive pupils', it is not some sound- bite - it is a call to action backed by specific measures. We will legislate to give head teachers the clear right to exclude disruptive pupils from school, without the fear of being overruled. We will enable heads to draw up binding home-school contracts setting out how children - and parents - should expect to behave when in school. They would be binding because if the parent won't sign, the child cannot attend.
Vitally, we will shake up the system for turning around disruptive and excluded children so that they are not just put in taxis to expensive and often poorly performing pupil referral units, or left on the streets to turn to crime. We will set out how social enterprises, such as the Amelia Farm Trust in Wales, or the Lighthouse Group in Bradford, both of which I visited recently, can access state funding to do the job properly. When I say I oppose nationwide selection by 11 between schools, that does not mean I oppose selection by academic ability altogether. Quite the reverse. I am passionate about the importance of setting by ability within schools, so that we stretch the brightest kids and help those in danger of being left behind.
With a Conservative Government this would be a motor of aspiration for the brightest kids from the poorest homes - effectively a 'grammar stream' in every subject in every school. Setting would be a focus for Ofsted and a priority for all new academies.
This is the one thing which will really help bright kids succeed in particular subjects. I remember at my school our year group was divided into three streams, but we remained in the same class for every subject. I was rubbish at all science subjects yet was still in the top stream for them. Only in Maths were we split up in the third year (13-14 yrs). I was moved down a group in Maths and it helped be hugely. Instead of being one of the worst in the class, I became one of the best in the new class which helped my confidence no end. I doubt I would have got my O Level without it.
