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.

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 your employment will be terminated unless you receive certification, in writing, that your continued employment advances the public interest.
