Under 1919.4(a), who decides whether to approve or deny an accreditation application?
The Assistant Secretary is the official who approves or denies an accreditation application. The regulation states the Assistant Secretary shall approve or deny applications and may conduct an investigation (including a hearing) before reaching a decision; the applicant should therefore expect the decision to come from that office. See 1919.4(a) and the general 1919 rule for context.
