Are there feasible alternatives to the present up-or-out policy for U.S. military officers? Most military officers are subject to a policy known as 0up-or-out, which requires separation from service if they are not promoted or selectively continued within a certain period of time or when they encounters established grade/tenure limits. RAND considered a range of potential substitutes for, or modifications of, the existing policy and recommends that the Department of Defense implement four demonstration projects to establish the relative value of specific policy alternatives and requirements.
