What is Revision?
Revision meaning As defined in the Federalwide SF424 (R&R): An application that proposes a change in 1) the Federal Government’s financial obligations or contingent liability from an existing obligation, or 2) any other change in the terms and conditions of the existing award. Note in general for NIH applicants, #2 would not require the submission of another application. NIH grantees use revision applications to request an increase in support in a current budget period for expansion of the project’s approved scope or research protocol. Applicants must apply and undergo peer review. The previous NIH term was “competing supplemental.” NOTE: The former NIH term “revision,” is now “resubmission”. A revision has a suffix in its application identification number; e.g., S1.
