— Not available. ‡ Reporting standards not met. 1 Institutions that awarded 20 or more doctor's degrees during the previous academic year. 2 Institutions that awarded 20 or more master's degrees, but less than 20 doctor's degrees, during the previous academic year. NOTE: The coverage of this table differs from similar tables published in editions of the Digest prior to 2003. Previous tenure tabulations included only instructional staff classified as full-time faculty; this table includes all staff with full-time instructional duties, including faculty and other instructional staff. Data for 1993–94 are for institutions of higher education, while later data are for degree-granting institutions. Degree-granting institutions grant associate's or higher degrees and participate in Title IV federal financial aid programs. The degree-granting classification is very similar to the earlier higher education classification, but it includes more 2-year colleges and excludes a few higher education institutions that did not grant degrees. (See Guide to Sources for details.) Data are for degree-granting institutions with 15 or more full-time employees; institu-tions with fewer than 15 employees did not report staff data prior to 2007. Some data have been revised from previously published figures.
