Data from the 1973 "Community and Junior College Directory" were analyzed to identify differences between full-time and part-time faculty. The data factors analyzed include: (1) type of control (public or private); (2) basic type of program (occupational, academic, both); (3) years in operation; (4) geographic region; (5) number of students; (6) number of faculty; (7) student/faculty ratio. Percentage of part-time faculty was fairly stable around the country at 35-40 percent. An exception to this was the Pacific Northwest, with a part-time faculty percentage of 60 percent. This suggests an insufficient supply of full-time instructors in a broad range of disciplines. Percentage of part-time faculty bears no close relationship to the functions of control, scope, student-faculty ratio, size, or years in operation. The rather high percentage of part-time faculty tends to confirm the advantages that the two-year institutions have claimed to have over the four-year institutions, including lesser cost, flexibility in course and program offerings because of the absence of tenured faculty, and the availability of highly qualified instructors in very narrow subject areas. Disadvantages to the use of part-time faculty, particularly their inaccessibility to students beyond the classroom time, would seem to be offset by the advantages. (Author/NHM)
