§ 6. Eligible Lists Resulting from an Open and Promotional Examination.

An examination may be given both as open and promotional, for example when an insufficient number of eligibles are available for a full certification. The list of competitors passing the promotional examination shall be prepared separately from the list of competitors passing the open examination. The promotional eligible list shall be used first. When there is an insufficient number of competitors on the list to constitute full certification, the Secretary may authorize the certification of competitors from both the promotional and open eligible lists to constitute a full certification.
