When my daughter ‘failed’ her 11+, this was in the mid 80’s though, I was disappointed because certain boys in her year ‘passed’, and I knew she did better than them in the routine school work, weekly tests and suchlike.
However, her very wise headmaster told me that although she worked hard, was a diligent pupil, no trouble to teach, boys developed later than girls, and by the time they were in their early teens, these same boys would have matured educationally, and be much brighter, if that makes sense, than my hard working girl.
And this proved to be the case. These same boys who I had written off achieved much as they grew older.
I won a Dux medal (Scottish top of school), numbers 2 +3 were also girls, so got no prize. when no 2 was a boy, he got a runner up prize.
I won a scholarship to a convent school, but my parents decided to move, so lost out, but instead of negotiating transfer, they sent me to an experimental comp. instead of the grammar. Often you found that it was not necessarily the school, but parents who decided that the cost of uniform and extra-curricular needed for many grammars, would be better spent on brothers and girls needed cookery and needlework
A really great culture where you could be in top class for English and remedial for maths, and continuous assessment meant that late bloomers could move up. (A classmate 11+ failure went to Uni with 4 As, 2 at A* after getting help with his reading). Modern comps do not seem to run this way.
