The 1999 National Study of Postsecondary Faculty (NSOPF:99) was sponsored by the U.S. Department of Education's National Center for Education Statistics (NCES). The Gallup Organization conducted the third cycle of NSOPF, which included 960 degree-granting postsecondary institutions and an initial sample of 28,700 faculty and instructional staff from these institutions. NSOPF:99 was designed to provide a national profile of faculty, including their professional backgrounds, responsibilities, workloads, salaries, benefits, and attitudes. This third cycle followed the first NSOPFconducted in 198788 with a sample of 480 institutions (including 2-year, 4-year, doctorate-granting, and other colleges and universities), more than 3,000 department chairpersons, and more than 11,000 facultyand the 1993 NSOPF, with a sample of 974 public and private not-for-profit degree-granting postsecondary institutions and 31,400 faculty and instructional staff. Additional information on the first two cycles of NSOPF is available at the NCES website.
A two-stage stratified, clustered probability design was used to select the NSOPF:99 sample. The institution universe for the survey was defined by the following criteria: Title IV degree-granting institutions;1 public and private not-for-profit institutions;2 institutions that conferred associate's, bachelor's, or advanced degrees; and institutions that were located in the United States. This definition covered most colleges (including junior and community colleges), universities, and graduate and professional schools. It excluded institutions that either offered only less-than-2-year programs; were private for-profit; or were located outside the United States (e.g., in U.S. territories). In addition, it excluded institutions that offered instruction only to employees of the institutions, tribal colleges, and institutions that offered only correspondence courses. According to the NCES Integrated Postsecondary Education Data System (IPEDS), 3,396 institutions met these criteria and were eligible for the NSOPF:99 sample. The first-stage sampling frame consisted of this group of institutions, stratified based on the highest degrees offered and the amount of federal research dollars received. The strata distinguished public and private institutions, as well as several types of institutions based on the Carnegie Foundation's classification system.3
Each institution was asked to complete an Institution Questionnaire and to provide a list of all faculty and instructional staff at their institution. Unlike NSOPF:88, which was limited to faculty whose assignment included instruction, the faculty universes for NSOPF:93 and NSOPF:99 were expanded to include all those who were designated as faculty, whether their responsibilities included instruction, and other (nonfaculty) personnel with instructional responsibilities. Teaching assistants were not included in any cycle of NSOPF. Institution coordinators were asked to provide a list of these full- and part-time faculty and instructional staff who had faculty status or instructional responsibilities during the 1998 fall term (i.e., the term that included November 1, 1998).
Of the 960 institutions in the sample, one was ineligible because it had merged with another institution. A total of 818 institutions provided lists of faculty and instructional staff, for a weighted list participation rate of 88.4 percent. A total of 865 institutions returned the institution questionnaire, for a weighted response rate of 92.8 percent. Initially, 28,600 faculty and instructional staff were selected from institutions that provided a list of their faculty and instructional staff. A subsample of 19,800 faculty and instructional staff was drawn for intensive follow-up. Approximately 18,000 faculty and instructional staff questionnaires were completed, for a weighted response rate of 83.0 percent. The overall weighted faculty response rate (institution list participation rate multiplied by the faculty questionnaire response rate) was 73.4 percent.
Faculty nonresponse bias analyses did not detect any bias. Item nonresponse occurred when a respondent did not answer one or more survey questions. The item nonresponse rates were generally low for the faculty questionnaire. For more information about NSOPF:99, including a full description of faculty and item nonresponse, see the 1999 National Study of Postsecondary Faculty: Methodology Report (NCES 2002154).
As described in the section of the text on "Data and Measurement Issues," the race/ethnicity data available in NSOPF:99 were combined into collapsed categories for comparison purposes with the NSOPF:93 survey. However, additional information about the more detailed race categories, and about respondents with more than one race, is available. Respondents who indicated in the ethnicity question on the survey that they were Hispanic or Latino were grouped together, regardless of the race categories they selected. Then, those who selected more than one race category were grouped together. Finally, remaining respondents were placed in the race category they selected. Both the distribution of the full NSOPF:99 sample and the distribution of the subsample used for analyses in this report, full-time faculty and staff with instructional duties for credit, are shown.
