Carnegie Classification
Also called Carnegie Classifications · R1 · Basic Classification · Institutional Classification
The 2025 redesign split what used to be a single Basic Classification into an Institutional Classification and a Research Activity Designation.
Carnegie Classification is a typology of U.S. degree-granting colleges published by the Carnegie Foundation and ACE. It groups institutions by what they award and, separately, by research activity. It is not a ranking, not an accreditor, and not a quality score. An MBA sits inside an institution that has a classification; the MBA is not itself “R1.”
How is the 2025 version built?
The 2025 redesign split what used to be a single Basic Classification into an Institutional Classification and a Research Activity Designation.
Institutional Classification uses three dimensions on a three-year average of IPEDS data: award-level focus (what degree levels the institution actually confers, not only the highest), academic program mix, and size. Those dimensions currently yield 31 groups. Inclusion requires that the institution conferred at least one degree in 2022–23 as reported to IPEDS.
Research Activity Designations are a separate label. For 2025, Research 1 is a threshold, not a quota: at least $50 million in total R&D spending and 70 research doctorates, using the higher of a three-year average or the latest year. Spending comes from the NSF HERD survey; doctorates come from IPEDS. Research 2 remains at least $5 million in research spending and 20 research doctorates. There is no cap on how many institutions can clear either bar.
| Label | What it is | What it is not |
|---|---|---|
| Institutional Classification | 31 groups by degree mix, fields, size | A rank order of quality |
| R1 | $50M R&D and 70 research doctorates | A business-school ranking |
| R2 | $5M R&D and 20 research doctorates | Accreditation |
Example: A public university clears R1 on HERD spending and Ph.D. output. Its MBA may still be a small professional program with no doctoral research of its own. Copy that says “an R1 MBA” attaches the parent campus label to a degree the classification does not grade.
How does it differ from rankings and accreditation?
U.S. News, FT, and QS sort MBA programs with weighted indicators. Carnegie sorts institutions with IPEDS and HERD. Accreditation is a yes/no review by a recognized accreditor. A campus can be R1, institutionally accredited, and unranked in FT because it did not opt in.
Common errors
- Using R1 as a synonym for “top MBA.”
- Treating Carnegie as an accreditor.
- Comparing 2021 Basic labels with 2025 Institutional labels as if the names still mean the same thing.
- Applying R1 to a standalone business school that does not grant research doctorates.
FAQ
Is R1 a ranking?
No. It is a threshold. Every institution that meets the spending and doctorate tests is R1. There is no #1 inside the designation.
Does Carnegie classify online MBAs separately?
No. The unit is the institution, using IPEDS completions and enrollment. Modality of one master’s program does not create a Carnegie category.
Where do I look up a school?
carnegieclassifications.acenet.edu. Do not use a media ranking table as the source.
Can an unaccredited school have a Carnegie class?
The 2025 universe is institutions that reported completions to IPEDS. Absence from Carnegie is not itself the legal finding of non-accreditation; check the Department of Education.
