Every journalist and educator in the US seems to have replaced “English” class with “English Language Arts.” Why? I can’t find a decent explanation online. Some websites claim that “Language Arts” consist of many different aspects of language: reading, composition, grammar, etc. But so does “English.”
Maybe teachers of English wanted a longer title. Or maybe referring to English as an “art” allows the teachers to assess students’ abilities subjectively, giving higher grades to everyone.
