This glossary is designed to promote awareness and use of a common language of terms, definitions, and procedures concerning postsecondary education at the institutional, state, and national levels. It may be especially useful to those who deal with data in institutions, governmental agencies, and educational associations. The alphabetically arranged entries are restricted to those that reflect established standards for data exchange and communication among the various components of postsecondary education. Standard classification structures have been established to achieve comparability in reporting, and some standards have been established and required for federal reporting. Standard definitions are required when institutions exchange information among themselves and when they report to state agencies, the federal government, and other organizations. There are 360 entries and subentries, and an appendix groups all substantive entries according to the following categories: academic, facilities, financial, general, personnel/employees, and students.
