2025 Carnegie R1 threshold — $50M R&D and 70 doctorates; 187 institutions designated

The American Council on Education and Carnegie Foundation's 2025 Carnegie Classifications of Institutions of Higher Education — Research Activity Designations (February 2025) sets the R1 ("Very High Spending and Doctorate Production") threshold at $50 million in annual total research expenditures and 70 research doctorates awarded annually, determined over three-year rolling HERD averages. 187 U.S. institutions are designated R1 in 2025, 28% more than under the 2022 methodology.

Two implications:

• For C-0005, the representative R1 profile in E-0086 (~$200M R&D) sits four times above the threshold floor, which is consistent with a mid-distribution institution. Expanding the analysis from a representative case to the full population multiplies the per-institution exposure by 187 to give a sector-wide first-order estimate.
• For C-0031, infrastructure investment is inseparable from R1 status: the threshold formalizes a quantity (R&D expenditure) that the ROI evidence in C-0031 is calibrated against. Institutions that fall below the threshold lose R1 designation; institutions that fail to invest in research infrastructure underperform on the R&D and doctorate metrics that determine the designation.
