The Center for Scientific Review (CSR) is the gateway for NIH grant applications and their review for scientific merit. We organize the peer review groups or study sections that evaluate the majority (75%) of the research grant applications sent to NIH. We also receive all grant applications for NIH, as well as for some other components of the U.S. Department of Health and Human Services (DHHS). Our Mission Since 1946, we have worked to see that NIH grant applications receive fair, independent, expert, and timely reviews—free from inappropriate influences—so NIH can fund the most promising research.
