Requirements Continued...

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-01/05/2027-unless otherwise stated in this vacancy announcement.

To receive credit for experience, 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. Failure to adequately provide information needed to determine number of hours worked in each position may result in that time not being credited when evaluating qualifying experience. For periods of time that reflect military service, the DD-214 or Statement of Service is sufficient to meet the full and/or part-time hours requirement as the service dates will be reflected.

Minimum Qualification Requirements: To qualify for this position, you must meet the following minimum qualifications:

Basic Educational Requirement AND/OR Specialized Experience for the series to which you are applying.
