Many people have asked where RCD programs typically report in the university hierarchy. We have data from about 140 institutions using the RCD Capabilities model including a mix of different Carnegie Classifications but dominated by R1 and R2 institutions (about 2/3 of the total). Here’s how they described their reporting relationship:
While the dominant model is within central or campus IT, quite a few programs are run out of a college, department, or institute, and nearly one in six are organized under the campus research office.
These data may not represent the entire community, but are at least one source on this question.
