This has always been the case in the UK through testing. In the 50’s, my husband has tested prior to Grade School. He went to the ‘brighter school’. His brother went to the ‘not-so-bright school’. Been going on for YEARS through the Socialist government.
Yes, and to me in the early 60’s. The secondary school you went to was by request and acceptance was based on test score in the 11+ exams.
However the Labour govt. in the late 60’s turned all of the secondary schools into “comprehensive” schools.
This was the true socialist method - you go to the nearest skool and everyone was the same - all brought down to the lowest level.
