This standard operating procedure (SOP) includes the following sections: Purpose, Procedure, Contacts, and Links.
To provide instruction for awarding competitive revision applications, which are requests from grantees for a significant expansion of a project's scope and for additional funds.
Grantees who want to expand their project's scope may request a revision (also known as a competitive revision or a competing supplement); however, they must submit an application, which must undergo peer review and be selected for funding. For more information on expanding scope, see What Constitutes a Change in Scope? in the Strategy for NIH Funding.
Investigators may apply for revisions only in response to a revision funding opportunity announcement (FOA) and only if the parent application has been funded. Revisions may not extend beyond that grant's project period.
*Note: In general, revision applications are not allowed for awards issued under a parent FOA with a single due date unless the revision FOA specifically states they are. Revision applications are generally allowed for awards issued under an investigator-initiated program announcement with multiple due dates. The revision FOA will define eligibility.
Also, revisions do no restore funds that were part of standard grant reductions.
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.
