Definition
Plain language
The official label for America's most research-heavy universities — the big-name research schools.
As stated in the literature
The Carnegie Classification tier for US doctoral universities with the highest research activity; there are 131 such institutions.
Also called: R1 universities
Why it matters: The label signals where the most intensive research and doctoral training happen, which shapes funding, reputation, and where major studies come from.
For example, a school like Harvard or MIT falls into the R1 category because of its heavy research output.
