About this role

Requirements Continued... Probationary Period: As a condition of employment for accepting this position, you may be required to serve a 1-year probationary period to evaluate your fitness and whether your continuation of employment advances the public interest. This probationary period is an extension of the appointment process and therefore requires the agency to determine if continued employment would advance the public interest, meet the organization goals and mission of the agency, and/or otherwise promote the efficiency of the service.

In determining if your employment advances the public interest, the agency will consider: your performance and conduct; the needs and interests of the agency; whether your continued employment would advance organizational goals of the agency or the Government; and whether your continued employment would advance the efficiency of the Federal service. Under applicable law, the employment of an individual serving a probationary or trial period automatically terminates when that period ends unless the agency affirmatively certifies, in writing, that the individual's employment should continue and that their appointment should be finalized.

In the absence of agency action to affirmatively certify continued employment beyond the probationary or trial period, such appointments are terminated. Upon completion of your probationary period your employment will be terminated unless you receive certification, in writing, that your continued employment advances the public interest. Qualifications: All qualifications must be met by the closing date of this announcement - 11/09/2026-unless otherwise stated in this vacancy announcement.

Competitive candidates must also meet Time-in-Grade requirements as defined in 5 CFR 300, Subpart F. For current Federal employees, if hours worked per week are not included on your resume, you must submit a non-award SF-50 as part of your application to be used to validate your work schedule and determine the amount of specialized experience that you will be granted. An award SF-50 will not be acceptable documentation for which to consider your amount of qualifying experience.
