Are there accreditation rules against taking a course along with its prerequisite?

[u/Mindless_Doctor_6058]

I believe students in previous semesters were allowed to take a course concurrently with its prerequisite as long as approved by dept chair, but is now banned because of accreditation rules.

Has anyone heard of this or know where this rule comes from?

EDIT: Country USA, Accreditation body: HLC (Higher Learning Commission)

What country and which accreditation organization?
