5 CFR § 213.102 - Identification of positions in Schedule A, B, C, or D.
(a) As provided in 5 U.S.C. 3302, the President may prescribe rules governing the competitive service. The rules shall provide, as nearly as conditions of good administration warrant, for -
(1) Necessary exceptions of positions from the competitive service; and
(b) The President delegated authority to the Office of Personnel Management (OPM) in Civil Service Rule VI to except positions from the competitive service when OPM determines that:
(1) Appointments thereto through competitive examination are not practicable; or
(2) Recruitment from among students attending qualifying educational institutions or individuals who have recently completed qualifying educational programs can better be achieved by devising additional means for recruiting and assessing candidates that diverge from the processes generally applicable to the competitive service.
(i) Upon determining that any position or group of positions, as defined in § 302.101(c), should be excepted indefinitely or temporarily from the competitive service, the Office of Personnel Management will authorize placement of the position or group of positions into Schedule A, B, C, or D, as applicable. Unless otherwise specified in a particular appointing authority, an agency may make Schedule A, B, C, or D appointments on either a permanent or nonpermanent basis, with any appropriate work schedule (i.e., full-time, part-time, seasonal, on-call, or intermittent).
(ii) When OPM establishes eligibility requirements (e.g., residence, family income) for appointment under particular Schedule A, B, or D exceptions, an individual's eligibility for appointment must be determined before appointment and without regard to any conditions that will result from the appointment.
(c) For purposes of making any such determinations, positions includes:
(1) Those that are intended to be removed indefinitely from the competitive service because the nature of the position itself precludes it from being in the competitive service (e.g., because it is impracticable to examine for the knowledge, skills, and abilities required for the job); and
(2) Those that are intended to be removed temporarily from the competitive service to allow for targeted recruiting and hiring from among a particular class of persons, as defined by the Office of Personnel Management, with the opportunity for the persons selected for those positions to convert to the competitive service at a later date.
