The National Study of Postsecondary Faculty, 2004 (NSOPF:04), is the last iteration in a series of studies that form the National Study of Postsecondary Faculty (NSOPF) program. NSOPF:04 (https://nces.ed.gov/surveys/nsopf/) is a cross-sectional survey that provides a national profile of postsecondary faculty and instructional staff: their professional backgrounds, responsibilities, workloads, salaries, benefits, and attitudes. The study was conducted using self-administered web-based questionnaires and a computer-assisted telephone interview (CATI) of postsecondary faculty and instructional staff. Postsecondary faculty and instructional staff in the academic term of Fall 2003 were sampled. The study�s weighted response rate was 76 percent for postsecondary faculty and 84 percent for institutions. Key statistics produced from NSOPF:04 are counts of faculty, faculty hires and departures, tenure of faculty, tenure policies, retirement and other benefits of faculty, faculty characteristics, employment history, current employment status including rank and tenure, workload, courses taught, publications, job satisfaction and attitudes, career and retirement plans, and benefits and compensation.
