David Cameron doesn't believe in grammar schools. You may have heard something on the news recently, as I understand it has been mentioned. David says there should be a 'grammar stream' in every comprehensive, removing the need for separate schools.
Grammars, are, I suppose, in their own way, special schools with special lessons for those with special needs, such as being bright or having extra potential. But David thinks all children should be educated at the same school. Usually.
Because, oddly, David does think there should be more special schools for those with what are more usually termed 'special needs' (ie the educationally subnormal, although I'm sure one isn't allowed to put it quite like that). He doesn't think there should be a 'special needs stream' in every school, though, which would have seemed the logical conclusion to draw.
Coincidentally, David doesn't have a child who may be eligible for a grammar school (at the moment, anyway), but does have one who needs a special needs school. I wonder why that is? Personally, I would simply put it down to the fact that he has experience of special needs schools, but knows nothing of comprehensives. Perhaps they should ask someone who does. Like me, for instance. My Consultancy fees are very reasonable.
