> To read and speak English? Ok, then why can't kids test out of it most of the time? Is the purpose to be knowledgeable about a canon of literature? Why can't people test against that?
Because people VASTLY overestimate their ability with their native language or their command of native language literature.
The SAT English Achievement tests used to absolutely obliterate even students who got good AP English scores. This isn't limited to English--even native Japanese speakers struggle with the advanced JLPT levels, for example. Grammar is hard, yo.
If you don't actively study your native language, your working vocabulary is quite small and your grammatical constructs are excessively simple.
As for shared literature, we were in front of what was claimed to be the house of Jonathan Swift with a bus full of tourists from various English-speaking countries, and the tour guide cracked a joke about "A Modest Proposal". I snickered a bit but didn't think much else. The tour guide pulled me aside later that I was the first person to get the joke and it was almost the end of the year--we're talking hundreds to thousands of people from the US, Australia, India, etc.
I mean, just ask someone to name three main characters and what they did in the last book they read. Most people will struggle. You need to spend some discussion time in order to affix a book into your memory.
