The tenure system is a ubiquitous feature of American higher education. Of the roughly 1,400 four-year institutions that the Carnegie Classification system categorizes as bachelor's, master's, or doctoral institutions, 87 percent reported that they have a tenure system. The present study provides information about the prevalence of general tenure practices and policies, including accommodations related to family obligations, as well as considerations of diversity, equity, and inclusion as they relate to the tenure process. Some of the survey questions were taken from the National Study of Postsecondary Faculty (NSOPF), administered four times between 1988 and 2004, in order to allow comparisons of how these features have developed over time. Other questions were included to capture recent developments in the tenure system. Yet another set of results provides information about the extent to which tenure continues to be threatened by institutional policies and practices, such as post-tenure review programs and replacements of tenure lines by faculty on contingent appointments. The results of this study can inform discussions on individual campuses about potential changes to prevailing tenure policies, practices, and standards.
