Additional information

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.

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.
