This glossary includes terms used in the Integrated Postsecondary Education Data System (IPEDS). IPEDS is the core postsecondary education data collection program in the U.S. Department of Education's National Center for Education Statistics. It is a single, comprehensive data collection system developed to encompass all institutions and organizations whose primary purpose is to provide postsecondary education. The IPEDS system is built around a series of interrelated surveys to collect institution-level data in such areas as enrollment, program completions, faculty and staff, and financing. The glossary includes a list of the IPEDS forms that are coded for quick identification and broken down by four- and two-year public and private, nonprofit/profit institutions. Also noted are on which specific forms some terms appear. (GLR)
