Don’t get much Chaucer in most “high schools” (i.e. their equivalents) here. At least I didn’t. Dickens and Shakespeare was mostly it.
Apart from the fact that English teaching isn’t great in the UK, it’s a product of the different system. I believe we get Chaucer at A-Level (which is what your high schools go to I think), but you only study a few A-Levels, if at all. Mine were all science or maths.
We got a bit of Chaucer at around age 14 or 15 in the school I went to, and it was by no means a school of excellence. We got the rated X Chaucer material in college. What clued me in on this story was I remember all of us 15 year olds giggling when we came to the line about the horse not being gay.
