I've just 'taken' a test from 1968 as posted by the Telegraph , it looks daunting and I think many modern school kids would struggle with it .
Walter .
It was intended to be daunting, Walter, we didn't want riff-raff blocking up our grammar schools, did we?
The 11-Plus was a mechanistic three part (in my case) examination which had no purpose other than identifying the top performing (say) 10% of the cohort. It was not criterion-based, it did not look for specific behaviour, it was norm-based - the top 10% performers, whatever their specific marks, were selected. Because girls of the same age are generally more mature physically and intellectually than boys there were frequent occasions when higher performing girls were denied grammar school places in favour of lower performing boys.
Because of its mechanistic nature, it was an examination that children could be
trained ... oops ... prepared for. I well recall the numerous ... err ... preparation sessions I
suffered underwent. A whole day was set aside for the test itself and the rest of the school had a holiday. I think you would have remembered it.
As an aside, and I stand to be corrected, the PISA assessment, which apparently allows countries to compare their secondary education systems has much in common with the old 11-Plus: it is mechanistic, trainable and rewards performance rather than creativity.
