I went to a Technical High School early 60's under the tri=partite system, decided by the 11 plus (Grammar if you passed the 11 plus tops, Technical High School if you did OK, Sec Mod if you didnt).
it was a new purpose built school with a very progressive head and keen young teachers. I loved the variety of what we did, dance drama, music, art, cookery and sewing, sports, plus all the usual all up to 16.
We didnt get a choice though about woodwork and metal work and technical drawing being girls.
I do recall however that somehow at 14 decision was made as to whether you were academic or not, because the "non academic" cohort did typewriting for the girls and the boys plumbing/electrics. We did a second language instead.
I wanted to do Art a level but was persuaded out of it by school and parents in favour of academic subjects English History Geography. Classes of 10/12 pupils!
At Uni doing English and History I realised that I was disadvantaged by not having a grammar school background in term of depth of study of English Lit especially, but wouldn't in retrospect have given up my dance drama, music, art, sewing.
As I was leaving schools locally were all slowly turning into comprehensives.
