Carnegie Classification of Institutions of Higher Education in the US

The Carnegie Classification of Institutions of Higher Education is a framework for classifying colleges and universities in the United States. The framework primarily serves educational and research purposes, where it is often important to identify groups of roughly comparable institutions. The classification includes all accredited, degree-granting colleges and universities in the United States that are represented in the National Center for Education Statistics Integrated Postsecondary Education Data System (IPEDS).

The Carnegie Classification was created by the Carnegie Foundation for the Advancement of Teaching (hereafter referred to as The Carnegie Foundation) in 1973. They issued reports in 1973, 1976, 1987, 1994, 2000, 2005, and 2010. To ensure continuity of the classification framework and to allow comparison across years, the 2010 Classification update retains the same structure of six parallel classifications, initially adopted in 2005. The 2005 report substantially reworked the classification system, based on data from the 2002–2003 and 2003–2004 school years.

General description
Information used in these classifications comes primarily from IPEDS and the College Board. The Carnegie Foundation lists classifications for particular institutions on their Institution Lookup website.

 * Primarily residential (R): (a)—at least 25 percent of degree-seeking undergraduates live on campus and (b) at least 50 percent but fewer than 80 percent attend full-time.
 * Highly residential (HR)—at least half of degree-seeking undergraduates live on campus and at least 80 percent attend full-time.

2005 edition
In contrast to previous classifications, the 2005 classification scheme provides a "...set of multiple, parallel classifications." According to Alexander C. McCormick, Senior Scholar at The Carnegie Foundation for the Advancement of Teaching and director of the classifications project, "The five new classifications are organized around three central questions: 1) What is taught, 2) to whom, and 3) in what setting?" In addition to the new classification categories, the previously used classification scheme ("Basic classification") has been revised.

The Carnegie Foundation is also developing one or more voluntary classification schemes that rely on data submitted by institutions. The first focuses on outreach and community engagement, and the second on "...how institutions seek to analyze, understand, and improve undergraduate education."

The Carnegie Foundation has no plans to issue printed editions of the classifications. Their website has several tools that let researchers and administrators view classifications.

Revisions in the basic classification
The "basic classification" is an update of the original classification scheme. In addition to changing names of some categories, the 2005 revision differs from previous editions in that it:


 * 1) Splits Associates colleges into subcategories. This is based on the work of Stephen Katsinas, Vincent Lacey, and David Hardy at the University of Alabama and is an update of work funded in the 1990s by the Ford Foundation.
 * 2) Categorizes doctorate-granting institutions according to their level of research activity. This level is calculated using multiple measures, financial and otherwise.
 * 3) Simplifies the measurement of doctorate degrees awarded.
 * 4) Divides Master's colleges and universities into three categories based on the number of Master's degrees awarded.
 * 5) Deprecates "Liberal Arts" terminology.
 * 6) Modified the criteria separating Master's and Baccalaureate institutions. Institutions formerly classified as Master's Colleges and Universities are now classified as Baccalaureate Colleges.
 * 7) Requires institutions to have higher levels of single-field or related-field concentration for designation as special-focus institutions and utilizes more sources of information to identify special-focus institutions.
 * 8) Splits the "Schools of engineering and technology" category into two categories and eliminates the "Teacher's colleges" category.
 * 9) Measures and classifies service academies using to the same criteria as other institutions.

Previous editions
Prior to the 2000 edition, the Carnegie Foundation categorized doctorate-granting institutions according to the amount of Federal funding they received. The 2005 edition categorizes doctoral-institutions according to their research support but uses a more complex formula than used in previous editions. Despite the fact that it is no longer used by the Carnegie Foundation, the descriptor Research I is still commonly used in reference to universities with the largest research budgets, often by the institutions themselves in their promotional materials.

2005 edition
In contrast to previous classifications, the 2005 classification scheme provides a "...set of multiple, parallel classifications." According to Alexander C. McCormick, Senior Scholar at The Carnegie Foundation for the Advancement of Teaching and director of the classifications project, "The five new classifications are organized around three central questions: 1) What is taught, 2) to whom, and 3) in what setting?" In addition to the new classification categories, the previously used classification scheme ("Basic classification") has been revised.

The Carnegie Foundation is also developing one or more voluntary classification schemes that rely on data submitted by institutions. The first focuses on outreach and community engagement, and the second on "...how institutions seek to analyze, understand, and improve undergraduate education."

The Carnegie Foundation has no plans to issue printed editions of the classifications. Their website has several tools that let researchers and administrators view classifications.

Revisions in the basic classification
The "basic classification" is an update of the original classification scheme. In addition to changing names of some categories, the 2005 revision differs from previous editions in that it:


 * 1) Splits Associates colleges into subcategories. This is based on the work of Stephen Katsinas, Vincent Lacey, and David Hardy at the University of Alabama and is an update of work funded in the 1990s by the Ford Foundation.
 * 2) Categorizes doctorate-granting institutions according to their level of research activity. This level is calculated using multiple measures, financial and otherwise.
 * 3) Simplifies the measurement of doctorate degrees awarded.
 * 4) Divides Master's colleges and universities into three categories based on the number of Master's degrees awarded.
 * 5) Deprecates "Liberal Arts" terminology.
 * 6) Modified the criteria separating Master's and Baccalaureate institutions. Institutions formerly classified as Master's Colleges and Universities are now classified as Baccalaureate Colleges.
 * 7) Requires institutions to have higher levels of single-field or related-field concentration for designation as special-focus institutions and utilizes more sources of information to identify special-focus institutions.
 * 8) Splits the "Schools of engineering and technology" category into two categories and eliminates the "Teacher's colleges" category.
 * 9) Measures and classifies service academies using to the same criteria as other institutions.

Previous editions
Prior to the 2000 edition, the Carnegie Foundation categorized doctorate-granting institutions according to the amount of Federal funding they received. The 2005 edition categorizes doctoral-institutions according to their research support but uses a more complex formula than used in previous editions. Despite the fact that it is no longer used by the Carnegie Foundation, the descriptor Research I is still commonly used in reference to universities with the largest research budgets, often by the institutions themselves in their promotional materials.
