This report analyzes the most complete data available on all types of higher education faculty. It examines the growth in part-time faculty and full-time nontenure track faculty using data from various sources, including national surveys by the National Center for Education Statistics. In this monograph, those faculty outside the traditional full-time tenure track are referred to as nontraditional faculty. The report also discusses the characteristics of nontraditional faculty. Results of the analysis suggest that in 1998 nontraditional faculty consisted mainly of higher education professionals with master's degrees. They were younger than traditional faculty and were likely to be female. Despite other income sources, the total income of nontraditional faculty was considerably lower than that of traditional faculty. Nontraditional faculty also received significantly less in nonmonetary compensation, such as health benefits and support for academic travel. Despite differences in pay and benefits, nontraditional and traditional faculty indicated similar levels of overall job satisfaction. Data indicate that nontraditional faculty, who now make up the majority in academe, can earn lower salaries and receive fewer benefits than their traditional colleagues, but they are almost as productive.
