About NIH Peer Review

Understanding the peer review process may improve your application. Funding applications undergo a peer review process by outside scientific experts, typically in a study section organized by NIH’s Center for Scientific Review (CSR) or NIDDK. For information about which types of applications are reviewed by NIH and NIDDK, view NIDDK’s Grant Review page. Specific criteria for review can be found in the funding announcement.
