What does "all level and discipline" means?

Question

quality education for all levels and discipline?

Answer 1

You would need to provide a bit more info for context but "discipline" means a type of study or a type of skill. In this case it probably means a branch of instruction or learning, like "the discipline of history" or "the discipline of mathmatics." So it probably means "all skill levels and all branches of..." whatever type of thing is being educated.

Answer 2

all levels means every level of education from the very young up to adult.  all disciplines means every single subject.  in higher education (like in a school intro guide) it includes the arts, sports, majors, etc.
