In fall 1998, U.S. colleges and universities employed about 1.1 million faculty and instructional staff. Of these, about 976,000 (91 percent) were identified as instructional faculty and staff who had some for-credit instructional responsibilities, including teaching classes for credit or advising or supervising students about academic activities for credit. These individuals were the core sample for this report. Throughout this report, faculty and staff who had some for-credit instructional responsibilities are called "instructional faculty and staff" or simply "faculty".
