Factors that have led to post-tenure evaluation of faculty are considered, along with concerns that should be examined before designing a post-tenure review process. Post-tenure evaluation is not in opposition to the principle of tenure and to policy statements about tenure issued by the American Association of University Professors, provided that the evaluation is not used as grounds for dismissal and that any recommended dismissal is subject to normal academic due process. Those who support the process view it as a formative way to reinforce faculty growth and improve instruction. Some proponents also suggest its usefulness in decisions about merit pay, promotion, and dismissal for cause. Criticisms of the process include the view that it will devalue rigorous pretenure evaluation and will erode collegial relationships. Before starting a post-tenure review process, colleges should: clearly articulate the purpose of the evaluation; involve faculty in the design of the plan and make sure faculty and administrators agree about specifics; emphasize flexibility and individualization; and link faculty development and rewards and post-tenure evaluation.
