Scotland’s original education system came out of the wider English/UK one, though - the grammar and secondary system pre-1965. In the sixties the whole system was upended in different forms, in not just each of NI, Wales, Scotland and England, but across different counties and cities as well (some retained the 11+ and some did not in England; NI retained grammars; Scotland abolished the Qualifying Exam which was the equivalent of the 11+, but retained some nominal grammars, and so on). They all retain some of that earlier form, and have a closer common history than elsewhere, with similar subject traditions.
In any case, why should Latin be singled out? Why not get rid of music subjects and programmes, orchestras, art and design as well? All superflous, old-fashioned and needlessly expensive.
Surely, no one who wanted to study architecture at university needs to bother with art, or design technology, at any earlier stage: they can easily learn it during their training. It’s useless in the modern world to learn to draw or paint or anything like that - it’s especially outmoded now we have AI to draw and design things for us, and anyone can learn to operate a CAD program to be honest. So I don’t see why we should teach those redundant subjects to state school students. After all, we can just get computers and AI to design buildings for us anyway these days - don’t you agree, @BlueSky2024 ?
