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.
