Under a DoD memo putting in place the general increase in the probationary period from one year to two, the longer period affects those hired by DoD into permanent positions in the competitive service or into the career SES on or after November 26, 2015. Those hired before that date will continue to complete a one-year period, if they haven’t already. The change doesn’t apply to those hired into the excepted service or to a supervisory probationary period, unless the individual is required to serve both that type of period and a regular period–in that case the two will run concurrently. Also: an employee transferring from another agency who has already completed a probationary period in the competitive service does not have to serve another probationary period; an employee transferring from another agency who receives a career appointment in the SES in the DoD must serve a two-year probationary period; and an employee transferring from another agency who has not completed a probationary period and is appointed to a position in DoD may be required to complete a new probationary period, with service toward completion of a prior period potentially being creditable toward the new period.
