I went to a girls' secondary modern school in Romford - a fairly working class area of outer London. I count myself as fortunate that our headmistress, who was Swedish, had some interesting and innovative ways of giving all pupils a chance to be creative, even though we had limited opportunities to succeed academically.
Each year there was a week-long arts festival/competition, which included solo singing, choirs, solo verse speaking, verse speaking choirs, dance, musical instruments, etc. etc. Professional adjudicators were brought in, and it was a most wonderful experience which everybody looked forward to and enjoyed. There were many after-school clubs, junior and senior choirs and a French choir - and we produced a school magazine (and this was in the early 60's). We also put on very polished drama and musical productions.
Despite my very happy memories of this school (we moved when I was 13 so I went to another - less enjoyable - school), I will never forget how much of a failure I felt when I did not pass the 11+. This was not helped by the school's limited curriculum which clearly sent a message that we were not really expected to be much more than shorthand typists, clerks or shop assistants. I would not wish this very real feeling of inferiority and this closing down of aspiration and choice to be placed on any 11 year old.
Theresa May has said she is so grateful that she went to a grammar school, and that is the reason she wishes to encourage more of them to be opened. This seems to indicate a very self-centred way of looking at things. As a vicar's daughter, it is likely she came from a fairly conventional, reasonably comfortable and well educated household. No doubt that type of "middle class" background was prevalent in her grammar school - research has shown it was in most grammar schools. To cite her own experience as a reason for bringing back a system that many learned people feel was detrimental to the vast majority of children seems to me to be putting her own misty-eyed emotions above research findings.
