5 U.S.C. § 5105 — Standards for classification of positions

The Office of Personnel Management, after consulting the agencies, shall prepare standards for placing positions in their proper classes and grades. The Office may make such inquiries or investigations of the duties, responsibilities, and qualification requirements of positions as it considers necessary for this purpose. The agencies, on request of the Office, shall furnish information for and cooperate in the preparation of the standards. In the standards, which shall be published in such form as the Office may determine, the Office shall—

The Office, after consulting the agencies to the extent considered necessary, shall revise, supplement, or abolish existing standards, or prepare new standards, so that, as nearly as may be practicable, positions existing at any given time will be covered by current published standards.

The official class titles established under subsection (a)(2) of this section shall be used for personnel, budget, and fiscal purposes. However, this requirement does not prevent the use of organizational or other titles for internal administration, public convenience, law enforcement, or similar purposes.
