Code of Federal Regulations Title 5. Administrative Personnel § 5.332.402 Referring candidates for appointment

OPM or a Delegated Examining Unit (DEU) will refer candidates for consideration by simultaneously listing a candidate on all certificates for which the candidate is interested, eligible, and within reach, except that, when it is deemed in the interest of good administration and candidates have been so notified, OPM or a DEU may choose to refer candidates for only one vacancy at a time. Selecting officials will receive sufficient names, when available, to allow them to consider at least 3 candidates for each vacancy.
