29 CFR 38.63: Authority and procedures for conducting post-approval compliance reviews.

(a) The Director may initiate a post-approval compliance review of any recipient to determine compliance with the nondiscrimination and equal opportunity provisions of WIOA and this part. The initiation of a post-approval review may be based on, but need not be limited to, the results of routine program monitoring by other Departmental or Federal agencies, or the nature or frequency of complaints.

(b) A post-approval review must be initiated by a Notification Letter, advising the recipient of:

(1) The practices to be reviewed;

(2) The programs to be reviewed;

(3) The information, records, and/or data to be submitted by the recipient within 30 days of the receipt of the Notification Letter, unless this time frame is modified by the Director; and

(4) The opportunity, at any time before receipt of the Final Determination described in §§ 38.95 and 38.96, to make a documentary or other written submission that explains, validates or otherwise addresses the practices under review.

(c) The Director may conduct post-approval reviews using such techniques as desk audits and on-site reviews.
