All accredited, degree-granting colleges and universities in the United States represented in the
National Center for Education Statistics IPEDS system are
eligible for inclusion in the Carnegie Classifications (as of the year a classification is issued,
and subject to the availability of required data). Accreditation status is based on information
provided by the U.S. Department of Education Office of Postsecondary Education. For more information
on accreditation, see
The classifications and categories are documented in this section. For a detailed explanation of how the
categories were defined and the data used, refer to the Methodology.
These classifications include all eligible institutions, subject to data availability. They are derived from national data on institutional characteristics and activities from sources such as the National Center for Education Statistics, the National Science Foundation, and the College Board.
Classifications are time-specific snapshots of institutional attributes and behavior based on data
from 2008 to 2010. Institutions might be classified differently using a different time frame.
These classifications rely on voluntary participation by institutions.
