Using data from the National Study of Postsecondary Faculty (NSOPF:93 and NSOPF:99), this report examines changes in the tenure status of full-time instructional faculty and staff at 2- and 4-year institutions between the fall of 1992 and 1998. It explores changes in tenure status by institutional level and control, program area, and the faculty's academic rank, gender, and race/ethnicity.
