Many high school Latin teachers are actually not very proficient in Latin, they are merely capable of teaching from a syllabus that is usually quite modest. Except for some elite schools, Latin is taught just to give students a taste of the language and expand their vocabulary in their native language by recognizing Latin borrowings. The pupils aren’t intended to actually master the language and read non-set texts comfortably, let alone follow Neo-Latin materials or practice spoken Latin. If the students surpass the syllabus, that makes things difficult for the teachers. If a student has taken up the language so enthusiastically, the teacher may simply demand that he/she simply test out of the course instead of continuing to come to class.
