The Institutional Characteristics (IC) Survey File of the Integrated Postsecondary Education Data System (IPEDS) provides basic data describing the universe of postsecondary institutions in the United States and its outlying areas. The data from the 10,074 reporting postsecondary schools are used for sample design and selection for other IPEDS studies and other postsecondary data collection activities. Data were collected in 1986-87 using three different forms. Data elements for the file include: (1) the name, address, and telephone number of each school; (2) numeric identifiers that can link this survey to other IPEDS surveys; (3) data pertaining to the highest level of programs offered; (4) data on institutional control; (5) school calendar system; (6) admissions requirements; (7) student services; and (8) student charges. Fall enrollment data were collected for some schools. TYPE OF SURVEY: National Survey; Longitudinal Survey. POPULATION: Postsecondary Education Institutions (12,594).
