5 CFR 302.102 - Method of filling positions and status of incumbent.
(a) To the extent permitted by statute and this chapter, each appointment, position change, and removal in the excepted service shall be made in accordance with any regulations or practices that the head of the agency concerned finds necessary.
(b) Except as authorized under paragraph (c) of this section, a person appointed to an excepted position does not acquire a competitive status by reason of the appointment. When an employee serving under a nontemporary appointment in the competitive service is selected for an excepted appointment, the agency must -
(1) Inform the employee that, because the position is in the excepted service, it may not be filled by a competitive appointment, and that acceptance of the proposed appointment will take him/her out of the competitive service while he/she occupies the position; and
(2) Obtain from the employee a written statement that he/she understands he/she is leaving the competitive service voluntarily to accept an appointment in the excepted service.
(c) Upon a finding by OPM that in a particular situation the action will be in the interest of good administration, OPM may authorize an agency to make appointments to specified positions in the excepted service in the same manner as to positions in the competitive service. Persons given career-conditional or career appointments pursuant to a specific authorization by OPM under this paragraph may acquire a competitive status as provided in part 315 of this chapter.
