Requirements Continued...

• You may be required to travel overnight away from home on occasion. You must obtain a government charge card for travel purposes.
• You may be required to complete training and obtain/maintain a government charge card with travel and/or purchase authority.
• Applicants must be at least 21 years old.

As a condition of employment for accepting this position, you will be required to serve a 1 year probationary period during which your fitness and whether your continued employment advances the public interest will be evaluated.
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.

• Prior to appointment, you must be determined physically fit by an authorized government physician to perform strenuous and physically demanding duties; and also pass a medical examination (which includes vision, hearing, cardiovascular, and mobility of extremities) given by an authorized government physician. You will also be required to undergo periodic medical examinations throughout employment.
• Prior to appointment, the people selected for these positions must be determined physically fit by an authorized physician to perform strenuous and physically demanding duties, pass a medical examination, and pass the Physical Efficiency Battery (PEB). The PEB is a fitness test consisting of five different components: 1) agility run - measures the ability to get up from the ground and sprint while changing directions; 2) bench press - measures upper body strength for one repetition; 3) 1.5 mile run - measures cardio/respiratory fitness; 4) sit and reach - measures flexibility in the lower back, legs and shoulders; and 5) body composition - measures body fat. Prior to appointment, selectees will be tested in all five components, and must pass the agility run, bench press and 1.5 mile run in the 25th percentile.

All qualifications must be met by the closing date of this announcement-02/11/2026-unless otherwise stated in this vacancy announcement.

Credit will be given for all appropriate qualifying experience. 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 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.
