From a survey designed to determine the current practices involved in faculty tenure and contract systems at colleges and universities throughout the U.S., it is estimated that 94.7% of faculty members work in institutions that have tenure systems. It is further determined that personnel practices in most institutions with tenure systems are characterized by: (1) at least an initial period of short contracts; (2) a high rate of the award of tenure after the final review; (3) no limitations on the percentage of tenured faculty; and (4) maximum probationary period ranging from 3 to 7 years, which may be reduced by credit for prior service in about two-thirds of the universities and private 4-year colleges. Personnel practices in most institutions with contract systems only are characterized by: (1) a high rate of contract renewal; and (2) provision of written reasons for nonrenewal of contracts. (HS)
