Opinions and recommendations regarding performance evaluations of tenured professors are presented. Some of the arguments in favor of post-tenure evaluation are that it could improve performance, ensure fair treatment, increase motivation, and rid colleges of incompetent faculty. Among the arguments against such a system are that it would defeat the purpose of tenure, threaten academic freedom, increase antagonism between administrators and faculty, and force professors who have already demonstrated competence through the rigorous tenure process to perpetually prove themselves.
