(a) The first year of service of an employee who is given a career or career-conditional appointment in the competitive service under the Civil Service Regulations is a probationary period when the employee:

(1) Was appointed from a competitive list of eligibles.

(2) Was reinstated (including reinstatement from a Reinstatement Priority List), unless during any period of service that affords a current basis for reinstatement the employee completed a probationary period of at least 1 year or served with competitive status under an appointment that did not require a probationary period; provided that the date of reinstatement begins a new 12-month probationary period if one is required under paragraph (a) of this section.

(b) A person who is required to go through a probationary period and then is transferred, promoted, demoted, or reassigned in accordance with the Civil Service Regulations before he or she completes such period is required to complete the remainder of the probationary period in the new position.

(c) Upon noncompetitive appointment to the competitive service under the Postal Reorganization Act (39 U.S.C. 101 et seq.), an employee of the Postal Career Service (including a substitute or part-time flexible employee) who has not completed 1 year of Postal service must serve the remainder of a 1-year probationary period in the new agency.

(d) A person who is appointed to the competitive service either by a special appointing authority or by conversion to a career or career-conditional appointment under the Civil Service Regulations must serve a 1-year probationary period unless specifically exempt from such period by the special appointing authority itself.

(e) Employees promoted, transferred, or otherwise assigned, for the first time, to supervisory or managerial positions shall be required to serve a probationary period under terms and conditions prescribed by the Office of Personnel Management (OPM). If an employee is required to concurrently serve both a probationary period in a supervisory or managerial position under 5 CFR part 315, subpart I, and a probationary or trial period following initial appointment or reinstatement under this Civil Service Rule, the latter takes precedence and fulfills the requirements of this paragraph.
