I was a little confused between the training materials and the quiz that I took. The section on Library or Learning Resources Center states: MOST schools are required to have some kind of library or learning resources center. Etc. Then the question on the quiz states: A Learning Resource Center (library) is required for ALL schools. Is it a requirement for ALL schools to have a Learning Resources Center (Library) or MOST schools? I did not take it to mean that ALL schools need one when the training said MOST...to me, that would mean that some are not required. Why is it required to have one?
