Why does the National Institutes of Health (NIH) have a limit of a single resubmission and set a time limit for the single resubmission allowed?
In general, it was noted that the likelihood of subsequent success decreased with an increasing number of amendments. To ensure that the largest number of high-quality and meritorious applications receive funding earlier and to improve system efficiency, NIH has decreased the number of allowed grant application resubmissions (amendments) to two (NOT-OD-09-003 and NOT-OD-09-016). This policy applies to all NIH extramural funding mechanisms that allow resubmissions whether reviewed in CSR or another NIH Institute/Center. Because of the pace of scientific discovery, NIH has chosen to limit the time for the resubmission.
