Vanilla: I do have an idea of grammar schools having attended one myself for seven years. Ditto my brother, ditto my DH, ditto DF.
But here's the caveat - I am not arguing that 'all grammar schools are bad'. The ones we attended were none of them any great shakes, but I am more than happy to admit that what schools were like 30+ years ago, (60+ in DF's time), is not necessarily how they would be now. What I am arguing against, is the stance that 'all comprehensives are bad'.
You on the contrary, have argued that:
You need to address the problem with poor results, teaching methods, culture in the comprehensive schools, not to debate about grammar schools.
of course not all of comprehensives are failing, but a very large number...
Tackle the poor education in comprehensives and address the issue of discipline, aspirations and standards for the students at the lower range of ability.
If a comprehensive has disruptive culture of low aspirations and poor quality of teaching, the bright students will suffer rather than benefit. You can't benefit from a bad school.
I don't understand why people channel all their passion to castigate pupils in selective schools instead of sorting the mess with bad comprehensive schools.
Need I give any more quotes. Forgive me if I infer from that, that you consider 'all comprehensives are bad'.
When you are asked for numbers of these dysfunctional comprehensives, you are strangely reticent to give any. When you are presented with information about successes in comprehensives, you avoid answering.
