What does teaching assistant mean? Recently, many people recruit teaching assistants! Do you have any experience? Does the teaching assistant tell the teacher directly?

Teaching assistant is the lowest rank of university teachers' titles, and it is the junior title of university teachers and teachers below lecturers. In principle, teaching assistants can't teach alone, or they can't teach all the courses of a subject. They should follow the lecturer or professor to revise their homework and assist them in teaching. Teachers' professional titles rank from low to high as teaching assistant, lecturer, associate professor and professor.
