Qualifications
Requirements Continued...
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 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.
All qualifications must be met by the closing date of this announcement-09/04/2026-unless otherwise stated in this vacancy announcement.
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. For periods of time that reflect military service, the DD-214 or Statement of Service is sufficient to meet the work schedule requirement as the service dates will be reflected. For all other applicants who are not current federal employees, your resume must state either "full-time" (or "40 hours a week") or "part-time" with the number of hours worked per week to ensure proper crediting of specialized experience.
To qualify for this position, you must have sufficient knowledge and ability in the following job-related factors:
- Ability to Do the Work of the position without More than Normal Supervision (SCREEN OUT)
If your knowledge and ability in the SCREEN OUT factor above is not sufficient, you will receive no further consideration.
