To award new funds to grantees through a revision application for a significant expansion of a project's scope.
Revision applications request funding to expand the scope of an existing grant. They do not restore funds that were part of standard grant reductions.
*Note: Revision applications are not allowed for funding opportunity announcements with a single due date unless the FOA specifically states they are. However, revisions are allowed for most investigator-initiated program announcements with multiple due dates.
Grantees who want to expand their project's scope and are allowed a revision (also known as a competing supplement), must apply for one and undergo peer review. For more information on expanding scope, see What Constitutes a Change in Scope? in the Strategy for NIH Funding.
Investigators apply to the parent announcement, but must wait until their application has been funded. Revisions may not extend beyond that grant's project period.
See the Administrative Supplements to Grants and Cooperative Agreements SOP for adding funds to a grant or cooperative agreement for purposes that do not significantly expand a project's scope.
Grantees with questions should contact the appropriate program officer or grants management specialist. For more information, read Communicating With NIAID—How to Get Help.
