34 C.F.R. § 602.28 – Regard for decisions of States and other accrediting agencies.

(a) If the agency is an institutional accrediting agency, it may not accredit or preaccredit institutions that lack legal authorization under applicable State law to provide a program of education beyond the secondary level.
(b) Except as provided in paragraph (c) of this section, the agency may not grant initial or renewed accreditation or preaccreditation to an institution, or a program offered by an institution, if the agency knows, or has reasonable cause to know, that the institution is the subject of—
1. (1) A pending or final action brought by a State agency to suspend, revoke, withdraw, or terminate the institution's legal authority to provide postsecondary education in the State;
2. (2) A decision by a recognized agency to deny accreditation or preaccreditation;
3. (3) A pending or final action brought by a recognized accrediting agency to suspend, revoke, withdraw, or terminate the institution's accreditation or preaccreditation; or
4. (4) Probation or an equivalent status imposed by a recognized agency.
(c) The agency may grant accreditation or preaccreditation to an institution or program described in paragraph (b) of this section only if it provides to the Secretary, within 30 days of its action, a thorough and reasonable explanation, consistent with its standards, why the action of the other body does not preclude the agency's grant of accreditation or preaccreditation.
(d) If the agency learns that an institution it accredits or preaccredits, or an institution that offers a program it accredits or preaccredits, is the subject of an adverse action by another recognized accrediting agency or has been placed on probation or an equivalent status by another recognized agency, the agency must promptly review its accreditation or preaccreditation of the institution or program to determine if it should also take adverse action or place the institution or program on probation or show cause.
(e) The agency must, upon request, share with other appropriate recognized accrediting agencies and recognized State approval agencies information about the accreditation or preaccreditation status of an institution or program and any adverse actions it has taken against an accredited or preaccredited institution or program.
