This brief publication summarizes data from the National Study of Postsecondary Faculty, 1988 and 1993, concerning the teaching workload of full-time college faculty. The following findings are highlighted: (1) In 1992, faculty members spent 54 percent of their work hours teaching, 18 percent conducting research, and 13 percent performing administrative tasks; (2) between 1987 and 1992, the percentage of time spent teaching decreased (from 57 to 54 percent) though the number of classroom and student contact hours increased; (3) generally, full professors spent a higher percentage of their time conducting research; assistant professors, instructors, and lectures spent the most time teaching; and (4) full-time faculty at 2-year institutions had substantially more student contact hours per week than did faculty at other institutions (87 percent more than those at liberal arts institutions and 67 percent more than those at research institutions). Tables and graphs present data on faculty time usage by academic rank and type of institution for 1987 and 1992. (DB)
